LASIK eye surgery provides a path to clear vision at any age. You can achieve freedom from glasses, contact lenses and endless prescriptions with a procedure that permanently improves the vision.
LASIK is a surgical procedure intended to reduce a person's dependency on glasses or contact lenses. LASIK stands for Laser-Assisted In Situ Keratomileusis and is a procedure that permanently changes the shape of the cornea, the clear covering of the front of the eye, using an excimer laser. A mechanical microkeratome (a blade device) which we use in Saluja Eye Care Center or a laser keratome, currently we are not using this in Saluja Eye Care Center, (a laser device) is used to cut a flap in the cornea. A hinge is left at one end of this flap. The flap is folded back revealing the stroma, the middle section of the cornea. Pulses from a computer-controlled laser vaporize a portion of the stroma and the flap is replaced. There are other techniques and many new terms related to LASIK that you may hear about.
Below is a video that summarizes some risks of LASIK surgery and other important information.
LASIK is applied for the treatment of:
This laser vision correction technique is performed on the cornea so that light entering the eye can be focused on the retina for clear vision.
We at Saluja Eye Care Center provide personalized LASIK treatment such as HD procedure takes both lower (myopia, hyperopia and astigmatism) and higher-order aberrations (halos, starbursts and glare) into consideration and delivers a treatment based on each eyes unique visual fingerprint. This procedure is the most advanced form of laser vision correction.
We also offer the LASIK based treatment of Presbyopia.
We can treat one or both eyes and provides good vision at all distances (near, intermediate and far). It does not differ from a normal LASIK treatment.
Six month after surgery, the vast majority of patients treated by us achieved the following:
Presbyopia LASIK :
Any surgical procedure that you elect can occur only after a careful evaluation of your eye and the type of refractive error that presently obscures your vision. The exact price is determined after a thorough examination of both the eyes and understanding your health history.
The complexity of your refractive error can affect the cost of your surgery, but you may expect to pay in the range of Rs 16,000 to 1,00,000 (approx.) for both eyes to achieve the most positive outcomes.

When glasses or contact lenses become a trouble in your life, LASIK surgery offers an alternative that can give you a clear vision again. The innovative technology treats the most common types of refractive errors that you may know as nearsightedness (myopia), farsightedness (hyperopia) and astigmatism. Changes in the structure of your eye that alter your vision may relate to age or to coping with the challenges that result from the way that you use your eyes. LASIK surgery offers a highly successful approach to permanently improving your vision without ever having to use glasses or contact lenses ever again.
How does wavefront LASIK (Zyoptix HD etc.) compared to conventional LASIK?
A: Wavefront adds an automatic measurement of more subtle distortions (called higher order aberrations) than just nearsightedness, farsightedness, and astigmatism corrected by conventional LASIK. However, these “higher order aberrations” account for only a small amount (probably no more than 10%) of the total refractive error of the average person’s eye. Conventional LASIK increases higher order aberrations. Although wavefront-guided treatments attempt to eliminate higher order aberrations, results from the clinical studies have shown that the average aberrations still increase, but less than they do after conventional LASIK. In a few studies comparing wavefront-guided LASIK to conventional LASIK, a slightly larger percentage of subjects treated with wavefront LASIK achieved 20/20 vision without glasses or contact lenses compared to subjects treated with conventional LASIK.
The safety and effectiveness of refractive procedures has not been determined in patients with some diseases. Discuss with your doctor if you have a history of any of the following:
Most patients are very pleased with the results of their refractive surgery. However, like any other medical procedure, there are risks involved. That's why it is important for you to understand the limitations and possible complications of refractive surgery.
Before undergoing a refractive procedure, you should carefully weigh the risks and benefits based on your own personal value system, and try to avoid being influenced by friends that have had the procedure or doctors encouraging you to do so.
Additional Risks if you are Considering the Following:
Monovision is one clinical technique used to deal with the correction of presbyopia, the gradual loss of the ability of the eye to change focus for close-up tasks that progresses with age. The intent of monovision is for the presbyopic patient to use one eye for distance viewing and one eye for near viewing. This practice was first applied to fit contact lens wearers and more recently to LASIK and other refractive surgeries. With contact lenses, a presbyopic patient has one eye fit with a contact lens to correct distance vision, and the other eye fit with a contact lens to correct near vision. In the same way, with LASIK, a presbyopic patient has one eye operated on to correct the distance vision, and the other operated on to correct the near vision. In other words, the goal of the surgery is for one eye to have vision worse than 20/20, the commonly referred to goal for LASIK surgical correction of distance vision. Since one eye is corrected for distance viewing and the other eye is corrected for near viewing, the two eyes no longer work together. This results in poorer quality vision and a decrease in depth perception. These effects of monovision are most noticeable in low lighting conditions and when performing tasks requiring very sharp vision. Therefore, you may need to wear glasses or contact lenses to fully correct both eyes for distance or near when performing visually demanding tasks, such as driving at night, operating dangerous equipment, or performing occupational tasks requiring very sharp close vision (e.g., reading small print for long periods of time).
Many patients cannot get used to having one eye blurred at all times. Therefore, if you are considering monovision with LASIK, make sure you go through a trial period with contact lenses to see if you can tolerate monovision, before having the surgery performed on your eyes. Find out if you pass your state's driver's license requirements with monovision.
In addition, you should consider how much your presbyopia is expected to increase in the future. Ask your doctor when you should expect the results of your monovision surgery to no longer be enough for you to see near-by objects clearly without the aid of glasses or contacts, or when a second surgery might be required to further correct your near vision.
You may choose to have LASIK surgery on both eyes at the same time or to have surgery on one eye at a time. Although the convenience of having surgery on both eyes on the same day is attractive, this practice is riskier than having two separate surgeries.
If you decide to have one eye done at a time, you and your doctor will decide how long to wait before having surgery on the other eye. If both eyes are treated at the same time or before one eye has a chance to fully heal, you and your doctor do not have the advantage of being able to see how the first eye responds to surgery before the second eye is treated.
Another disadvantage to having surgery on both eyes at the same time is that the vision in both eyes may be blurred after surgery until the initial healing process is over, rather than being able to rely on clear vision in at least one eye at all times.
Your doctor should screen you for the following conditions or indicators of risk:
If you are considering refractive surgery, make sure you:
Even the best screened patients under the care of most skilled surgeons can experience serious complications.
Under the care of an experienced doctor, carefully screened candidates with reasonable expectations and a clear understanding of the risks and alternatives are likely to be happy with the results of their refractive procedure.
Be cautious about "slick" advertising and/or deals that sound "too good to be true." Remember, they usually are. There is a lot of competition resulting in a great deal of advertising and bidding for your business. Do your homework.

What to expect before, during, and after surgery will vary from doctor to doctor and patient to patient. This section is a compilation of patient information developed by manufacturers and healthcare professionals, but cannot replace the dialogue you should have with your doctor. Read this information carefully, discuss your expectations with your doctor.
If you decide to go ahead with LASIK surgery, you will need an initial or baseline evaluation by your eye doctor to determine if you are a good candidate. This is what you need to know to prepare for the exam and what you should expect:
If you wear contact lenses, it is a good idea to stop wearing them before your baseline evaluation and switch to wearing your glasses full-time. Contact lenses change the shape of your cornea for up to several weeks after you have stopped using them depending on the type of contact lenses you wear. Not leaving your contact lenses out long enough for your cornea to assume its natural shape before surgery can have negative consequences. These consequences include inaccurate measurements and a poor surgical plan, resulting in poor vision after surgery. These measurements, which determine how much corneal tissue to remove, may need to be repeated at least a week after your initial evaluation and before surgery to make sure they have not changed, especially if you wear RGP or hard lenses. If you wear:
You should tell your doctor:
Your doctor should perform a thorough eye exam and discuss:
You should have the opportunity to ask your doctor questions during this discussion. Give yourself plenty of time to think about the risk/benefit discussion, to review any informational literature provided by your doctor, and to have any additional questions answered by your doctor before deciding to go through with surgery and before signing the informed consent form.
You should not feel pressured by your doctor, family, friends, or anyone else to make a decision about having surgery. Carefully consider the pros and cons.
The day before surgery, you should stop using:
These products as well as debris along the eyelashes may increase the risk of infection during and after surgery. Your doctor may ask you to scrub your eyelashes for a period of time before surgery to get rid of residues and debris along the lashes.
Also before surgery, arrange for transportation to and from your surgery and your first follow-up visit. On the day of surgery, your doctor may give you some medicine to make you relax. Because this medicine impairs your ability to drive and because your vision may be blurry, even if you don't drive make sure someone can bring you home after surgery.
The surgery should take less than 30 minutes. You will lie on your back in a reclining chair in an exam room containing the laser system. The laser system includes a large machine with a microscope attached to it and a computer screen.
A numbing drop will be placed in your eye, the area around your eye will be cleaned, and an instrument called a lid speculum will be used to hold your eyelids open.
Your doctor may use a mechanical microkeratome (a blade device) to cut a flap in the cornea
If a mechanical microkeratome is used, a ring will be placed on your eye and very high pressures will be applied to create suction to the cornea. Your vision will dim while the suction ring is on and you may feel the pressure and experience some discomfort during this part of the procedure. The microkeratome, a cutting instrument, is attached to the suction ring. Your doctor will use the blade of the microkeratome to cut a flap in your cornea. Microkeratome blades are meant to be used only once and then thrown out. The microkeratome and the suction ring are then removed.
Your doctor may use a laser keratome (a laser device), instead of a mechanical microkeratome to cut a flap on the cornea.
If a laser keratome is used, the cornea is flattened with a clear plastic plate. Your vision will dim and you may feel the pressure and experience some discomfort during this part of the procedure. Laser energy is focused inside the cornea tissue, creating thousands of small bubbles of gas and water that expand and connect to separate the tissue underneath the cornea surface, creating a flap. The plate is then removed.
You will be able to see, but you will experience fluctuating degrees of blurred vision during the rest of the procedure. The doctor will then lift the flap and fold it back on its hinge, and dry the exposed tissue.
The laser will be positioned over your eye and you will be asked to stare at a light. This is not the laser used to remove tissue from the cornea. This light is to help you keep your eye fixed on one spot once the laser comes on. NOTE: If you cannot stare at a fixed object for at least 60 seconds, you may not be a good candidate for this surgery.
When your eye is in the correct position, your doctor will start the laser. At this point in the surgery, you may become aware of new sounds and smells. The pulse of the laser makes a ticking sound. As the laser removes corneal tissue, some people have reported a smell similar to burning hair. A computer controls the amount of laser energy delivered to your eye. Before the start of surgery, your doctor will have programmed the computer to vaporize a particular amount of tissue based on the measurements taken at your initial evaluation. After the pulses of laser energy vaporize the corneal tissue, the flap is put back into position.
A shield should be placed over your eye at the end of the procedure as protection, since no stitches are used to hold the flap in place. It is important for you to wear this shield to prevent you from rubbing your eye and putting pressure on your eye while you sleep, and to protect your eye from accidentally being hit or poked until the flap has healed.
Immediately after the procedure, your eye may burn, itch, or feel like there is something in it. You may experience some discomfort, or in some cases, mild pain and your doctor may suggest you take a mild pain reliever. Both your eyes may tear or water. Your vision will probably be hazy or blurry. You will instinctively want to rub your eye, but don't! Rubbing your eye could dislodge the flap, requiring further treatment. In addition, you may experience sensitivity to light, glare, starbursts or haloes around lights, or the whites of your eye may look red or bloodshot. These symptoms should improve considerably within the first few days after surgery. You should plan on taking a few days off from work until these symptoms subside. You should contact your doctor immediately and not wait for your scheduled visit, if you experience severe pain, or if your vision or other symptoms get worse instead of better.
You should see your doctor within the first 24 to 48 hours after surgery and at regular intervals after that for at least the first six months. At the first postoperative visit, your doctor will remove the eye shield, test your vision, and examine your eye. Your doctor may give you one or more types of eye drops to take at home to help prevent infection and/or inflammation. You may also be advised to use artificial tears to help lubricate the eye. Do not resume wearing a contact lens in the operated eye, even if your vision is blurry.
You should wait one to three days following surgery before beginning any non-contact sports, depending on the amount of activity required, how you feel, and your doctor's instructions.
To help prevent infection, you may need to wait for up to two weeks after surgery or until your doctor advises you otherwise before using lotions, creams, or make-up around the eye. Your doctor may advise you to continue scrubbing your eyelashes for a period of time after surgery. You should also avoid swimming and using hot tubs or whirlpools for 1-2 months.
Strenuous contact sports such as boxing, football, karate, etc. should not be attempted for at least four weeks after surgery. It is important to protect your eyes from anything that might get in them and from being hit or bumped.
During the first few months after surgery, your vision may fluctuate.
Contact your eye doctor immediately if you develop any new, unusual or worsening symptoms at any point after surgery. Such symptoms could signal a problem that, if not treated early enough, may lead to a loss of vision.
What percentage of patients attain 20/20 vision or better without glasses or contacts?
A: Data in the Approval Orders and related documents summarizes the outcomes from the clinical trials submitted to the FDA for each approved device. Links to these documents are included on the FDA-Approved Lasers, page.
A. LASIK is a type of surgical procedure used to reshape the cornea to treat nearsightedness,farsightedness and astigmatism.
A. The surgeon makes a small ,hinged flap in the cornea and folds it back. Then a laser reshapes the cornea, which is located at the front of the eye. This improves the way the eye focuses light rays onto the retina,at the back of the eye,allowing for better vision.
A. Those who are-
A. Our aim is to make patient free from eye glasses but in spite of doing our best and taken all predictable objectives, we still cannot predict wound healing. It sometimes can heal leaving behind a small number. Success rates vary from patient to patient.
A. At least 18 years of age is the minimum requirement for the Lasik surgery.
A. As we age, the lens of the eye becomes more rigid and does not flex easily. As a result, for most people aged 40 and onwards it becomes more difficult to read close distance or in low light. It may be possible that you are suffering from presbiopia. If you are undergoing LASIK over the age of 40 and are interested in correcting your presbiopia, there are two options available for treatment-
A. Most patients see clearly within 24 hours after vision correction surgery but other take 2-5 days to recover. Some patients may experience some blurred vision and fluctuation in their vision for several weeks after LASIK.
A. Yes LASIK is safe for the patients who fulfills the eligibility criteria for the surgery.
A. In general, the success rate of LASIK is exceptionally high, especially for an elective surgery. Success is typically defined by quality of vision and patient satisfaction. According to journal of Cataract and Refractive surgery LASIK weighs in at 96% satisfaction.
A. With LASIK to correct your distance vision, you are likely to need reading glasses in your mid 40s. As it cannot prevent presbyopia, which is an age related loss of focusing power for seeing near objects.
A. Overall rate of severe complication is low,most LASIK complications can be treated without any loss of vision,but vision may rarely occur.
A. Most cases LASIK can fully correct astigmatism, the effect is permanent.
A. No the cornea is cut with the help of microkeratome contain a blade to create a flap in the cornea for LASIK procedure.
A. No LASIK will not make eyes prone to allergies from dust, despite the contact lens makes the eye more sensitive to dust and allergies and can make eyes itchy.
A. While lasik can greatly reduce the use of glasses or contact lenses throughout the day,it does not claim to eliminate the need fully. Everyone respond to the surgery slightly differently. Depending on the age and other vision condition, glasses may still be needed after LASIK surgery especially for reading.
A. The surgery usually takes place for 10-20 mins but the patient need to stay for 4-5 hours in total as the discharge is done after sometime of the surgery.
A. Lasik is typically a bilateral procedure, meaning it is performed on both eyes during the same surgical session. It is very safe and procedure takes only about 10 min per eye.
A. Once your consultation is done,you can go for the workup of LASIK and can book your surgery on the same day, then you have to come for the surgery on the allotted date and further for the followup.
A. LASIK cannot be done in person below 18 year of age. It is done only in adults above 18 years of age.
A. Basically, LASIK surgery treats the cornea and cataract surgery treats the lens of the eye. Treating one doesn’t inhibit treating the other. Which of course not only means that you can have cataract surgery after LASIK, but also that you can have LASIK after cataract surgery. However, the latter is becoming more of an unlikely scenario given the advancement in IOL technology. Premium IOLs can be fully customized to correct any refractive errors and potentially eliminate the need for a procedure like LASIK after cataract surgery.
A. Monovision- this technique corrects your vision to allow for near and intermediate vision in one eye and distance vision in the other eye.
A. Typically LASIK cannot help to correct a lazy eye,but there might be an exception. It is important to understand the risk of LASIK if you already have amblyopia. However, most doctors will not perform refractive surgery on the strong eye if the best corrected vision for amblyopic eye is 20/40 or less.
A. In most cases the improved vision LASIK surgery provide is permanent,but in a limited cases usually due to changes that can occur in the lens inside eye the refractive errors can return over time, causing blurry vision
A. In most cases LASIK dont hurt during or immediately after procedure. Before LASIK numbing eye drops are used to alleviate the pain or discomfort to the eye during the procedure. However after surgery patient may feel some pressure in eyes,but with medication that can be controlled.
A. Before LASIK surgery it is essential that you have a comprehensive eye checkup and consultation. During the examination, your eyes need to dilated to check the accurate measurements. If you have your LASIK consultation on the same day of your surgery, its important to realise that your eyes will not be dilated on that day because the dilation of pupil affect the positioning of the laser beam over the cornea. If dilation is necessary than surgery can be done on other day after your consultation.
A. There's no such systemic effect of LASIK surgery on the patient. It is a safe surgery with minimal complications related to the eyes.
A. Your consultant will prescribe you eye drops to prevent infection and inflammation and to keep your eyes moist. Do not use any eye drops not approved by your doctor. Healing after LASIK eye surgery usually occurs very rapidly and vision improved within a few days of surgery. Specific followup after surgery varies from one surgeon to another. You will revisit the doctor for evaluation 24 to 48 hours after LASIK as well as at regular intervals within the first 6 months.
A. While you can go for a swim two weeks following your surgery. Most importantly be sure to ask your eye doctor before going for a swim. After LASIK they will check your vision and eyes regularly to make sure they are recovering properly.
A. You may start driving as soon as you see well enough typically 2 to 3 days after the procedure. Driving at night should be avoided for 2 to 3 weeks as you might experience glare initially.
A. You can go to work after 2 to 3 days of your eye surgery as this much time will be require for the healing and clearing of the vision.
A. After LASIK eye surgery, your doctor will give you detailed instructions on how to properly care for your eyes during recovery. And it includes not wearing eye makeup for at least a week after surgery as it leads to infection and inflammation.
A. Certain risk factors involved in it are-
A. In most cases the improved vision LASIK surgery provides is permanent.But in a limited number of cases, usually due to changes that can occur in the lens inside the eye, with or without LASIK surgery some nearsightedness, farsightedness and/or astigmatism can return over time, causing blurry vision. If a regression of this sort occurs and becomes bothersome, a follow-up procedure called LASIK enhancement usually can be performed to restore clear vision.
A. Laser Eye surgery is one of the safest medical procedures carried out. there is an incredibly small chance of going blind as a result of Laser Eye Surgery. The bottom line is only 1 in 5 million may lose sight in one eye.
A. If you are not a good candidate for LASIK, then you may be eligible for one of these alternatives-
A. It is a LASIK surgery to treat presbyopia after the age of 40.
It is a unique , clinically proven laser procedure designed to help patients see objects close up again while maintaining your distance vision. It treats one or both eyes and provides acceptable vision at all distances( near, intermediate, far)
A. In proscan LASIK your vision get treated whereas in Zyoptix HD along with vision, the higher order aberrations also get treated like glare, starbursts, halos, vision at night get improved.
A. As per the doctors advise patient need to rest for 2-3 days before starting there routine normal activity of work.
A. LASIK- Lasik laser vision correction is a great procedure in which tissue is precisely ablated (burned/ vaporized) using excimer laser to reshape the cornea and thus remove the spectacle power. However Lasik entails making a flap with a mechanical blade called microkeratome.
FEMTO LASIK- And FemtoLasik compared to Lasik, corneal flap is created with the help of another cutting laser called Femtosecond laser. The introduction of Femtosecond laser increased the precision and accuracy of flap making as compared to the microkeratome blade. Hence Femto-lasik was also called bladeless LASIK. The overall outcome of LASIK AND FEMTO LASIK are similar.
SMILE-SMILE was developed to make two lamellar planes in the cornea with the help of a Femto laser, carving out a corneal lenticule. The thickness of the lenticule determines the amount of specs power correction. The lenticule is removed from the eye through a small incision of 2 to 4 mm. The technology was conceived to reduce chances of dry eyes and chances of compromising the strength of the cornea.
A. The results wanted after the surgery is. +/- 0,50. After the operation, it is necessary to do check-ups every 6 months. If the results aren’t good enough, there can be another surgery applied if the conditions of the eye and cornea is in good shape.
A. The UV lights from the sun may damage your eyes and cause some pain. It is recommended to avoid sun and use sunglasses if needed for a few weeks.
This procedure is recommended to correct the spectacle power in people over the age of 40 years. After the age of 40 years, the natural lens of the eye becomes hard and non-flexible and therefore loses its ability to change focus from distance to reading.
An eye is like a camera with a lens focusing light on the retina. Glasses are required if the image is out of focus. In RLE the natural lens is replaced by an artificial lens of suitable power to bring the image to focus on the retina without the need of glasses.
A simple way to understand is that the natural lens of the eye has the power of +21 Diopters. If a person has a spectacle power of -8 Diopters, then by exchanging the natural lens with an artificial lens of the power of +13, the spectacle power of -8 Diopters would stand corrected. However, practically calculations are not this simple. Ultrasound, biometry or costly optical biometers like the Lenstar have to be used to accurately determine the power of a lens which is to be implanted in the eye.
i) Monofocal Lens
It is a single power lens ,this lens would enable the person to see clearly without glasses. Since this lens is a hard, non-flexible artificial lens, it would not change its power to focus for near distances, therefore for reading purposes, a spectacle power of approx. +2.5 is required.
Since an average person’s activity involves 95% of distant viewing and only 5% of near viewing, a person tends to be very comfortable from this newly formed freedom of glasses, and he does not mind using glasses occasionally for reading.
ii) Multifocal Lens
For people desirous of having an excellent functional vision for distance and reading, the multifocal lens provides one such option. The lens has rings of Fresnel prisms that divide the incoming light into two bundles, one focused for distance and one for near, thereby giving the person the advantage of seeing both for distance and near without glasses. However multi-focal lenses can sometimes be associated with halos and glare around light and slight loss of contrast. Most of the people can adapt to these problems over a period without losing out on the advantages of spectacle free distance and near vision.
Presbyopia or decrease in near vision with age. In a young individual, the natural lens of the eye is soft and flexible and works like an auto-focus lens. By contraction of the internal eye muscles, it can change its power from a distance to near.
Around the age of 45, the natural lens of the eye undergoes age changes and tends to become hard and non-flexible. Even with contraction of internal eye muscles, it is unable to change its power from a distance to near therefore additional spectacle power is required for reading purposes.
In the elderly, the eye requires a distance and a near spectacle power. The laser can correct only one power either for distance or near. In mono-vision, one eye is corrected fully to focus it for distance, and other, partially for near. Thus with both eyes open, the person can do most of his routine activities without glasses and only for very fine work does a person need glasses.
