We commonly encounter a lot of questions asked by interested parties about LASIK and the LASIK surgery procedure. So we try to make it easy for you to do some research about LASIK surgery and have compiled a FAQ list about LASIK for you. What are my reasons for considering Vision Correction Surgery?There are many types of vision correction surgery, and LASIK is one of them. Your surgeon will need to understand why you wish to have corrective surgery. Is it for Career reasons Lifestyle reasons (sports, leisure activities, etc) Cosmetic reasons Reduce dependence on glasses and/or contact lenses Based on the reasons given, your surgeon will be in better position to recommend you the appropriate type of vision correction surgery. Am I a good candidate for Vision Correction Surgery?You will need to go through a comprehensive pre-procedure assessment, where the Optometrists and Ophthalmologist will check your eyes thoroughly in order to determine your suitability for LASIK. Here are some factors to determine your suitability: Has your vision been stable long enough to have Vision Correction Surgery? If your spectacle power is still increasing, it would be advisable to wait till it stabilises. Do you participate actively in contact sports? Activities which increase the risk of trauma to the eyes, for e.g. martial arts, or even football, would increase the risk of LASIK flap dislocations. Fortunately, the PRK (advanced surface ablation) techniques avoid this risk and may be more suitable under these circumstances. What is your corneal shape and corneal thickness? Patients that have evidence of Keratoconus (coned-shaped cornea) are not suitable for LASIK. This is a condition where the cornea becomes thinned out and weakened causing unusual astigmatism and poor vision. in these cases, implantable collamer lens (ICL) would be a better/safer option. Are you currently pregnant or breastfeeding? Hormonal changes and corneal pressure due to fluid retention can cause vision fluctuations of a woman who is pregnant or currently nursing. To have the best PRK, LASIK and other types of vision correction surgery results, it is advisable to undergo the procedure at a time when women are neither pregnant or breastfeeding. Do you have dry eyes? If you have an existing condition of dry eyes, you may be advised to have that treated prior to vision correction surgery (e.g. PRK, LASIK etc.) – since the quality and the quantity of tears you produce are factors in the development of dry eyes and can also affect healing after eye surgery. In addition, good LASIK outcomes may depend on controlling dry eyes. What are the things I should note before LASIK surgery?You will be advised on the following before you come in for your pre-LASK assessment for suitability and before the actual day of the LASIK surgery. Do not wear soft contact lenses 7 days before your first pre-LASIK assessment and before surgery. Do not wear hard contact lenses (RGPs) 14 days before your first pre-LASIK assessment and before surgery. Do not apply any eye makeup 2 days before surgery. Do not apply any perfume on the day of surgery. Do not apply any products on your eyes or face on the day of surgery. Bring your sunglasses on the day of LASIK surgery as you may experience glare after LASIK surgery. You do not need to fast before the LASIK surgery, there is no food restriction. Do not drive on the day of LASIK surgery. Expect to stay for about 2 hours, even though the LASIK procedure will only take about 30 minutes. What happens during a LASIK Surgery procedure?The LASIK procedure typically takes about 25 minutes for both eyes. Improved vision (without corrective eyewear) is achieved very soon after surgery, usually within a few hours. Your eyelids will be cleaned and anaesthetic eye drops will be administered into your eyes to prevent pain. You will be guided into the laser room where a laser is used to create a protective flap in the cornea. You will rest for a while in order to allow the bubbles under the flap to clear. Next, the cornea flap is gently lifted back and laser treatment is used to correct the degree of the eye. The laser beam reshapes the cornea based on an individual’s required vision correction. During this your eyelids will be held open by a springy device during the laser treatment and you will be asked to fixate your vision on a light. (Note: The surgery is painless and does not take long) The protective flap is then repositioned into place and allowed to heal. You will rest your eyes at our recovery area for around 30 mins before a final check is done. After the surgery, it is advised that you go home and rest. Lasik Procedure What to note after LASIK Surgery?You should rest at home after surgery, observe good hygiene and adhere to the following. For one week: NO exercise which gets sweat in your eyes (you can use a sweat band and exercise in a clean indoor gym environment) NO water & soap in contact with your eyes NO makeup and eye products DO NOT rub or scratch your eyes Wear sunglasses outdoor Eyeshield to be worn sleeping/nap time Eye drops should be instilled regularly Should I be worried about Vision Correction Surgery complications?With advancing technology, sophisticated surgical skill and optimal patient selection today, the safety and effectiveness of vision correction surgery continue to improve. Laser eye surgery has successfully treated millions of patients and has high patient satisfaction rates. However, as with any surgery, it has potential complications. It is important for you to weigh the benefits and risks before choosing to go ahead with surgery. PRK and LASIK Surgery has a very good safety profile and a very high success rate. However, like any other surgery, there are potential side effects that one should be aware of and must be able to accept a small amount of risk. Proper testing before the procedure can identify patients who are at a high risk for long-term risk for long-term complications. There maybe some visual aberrations such as – glare, double vision, ghosting, halos, starbursts, and problems with low-light or night vision, and experience dryness of the eyes. These are the more common side effects of PRK and LASIK. Most patients experience some of these symptoms immediately after the surgery but they improve as they recover, so most require no treatment. Dry eyes This is fairly common and almost all LASIK patients experience some degree of dry and gritty feeling during the recovering period following LASIK. This can be eased with the frequent use of lubricating eye drops. Night Vision Problems During the first few weeks or months, one might experience halos, glare and starbursts at night. This condition usually improves with time. Under-correction, over-correction, or astigmatism In some cases, corrective eyewear or contact lenses may still be required for the few activities which are more visually demanding. This can be due to the laser removing too little or too much tissue, or can be caused by variance in the way each eye heals after surgery. An enhancement procedure may be done in such cases.
