We commonly encounter a lot of questions asked by interested parties about Laser Vision Correction Surgery (e.g. PRK, LASIK, ICL etc.) So we try to make it easy for you to do some research about the surgery and have compiled a FAQ list for you. What are my reasons for considering Vision Correction Surgery?There are many types of vision correction surgery. 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 Laser Vision Surgery. 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 abalation) 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 is 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 to expect after PRK?Some patients may encounter blurry vision for the first few weeks and may need glasses for night driving or reading until their vision stablises. Your eyes may feel sensitive and some might experience side effect such as haze due to ‘over-healing’. However, these risks can be much reduced with the prescription eyes drops and medication. 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 · Eye shield 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 continues 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. Any side effects and/or complications of Vision Correction 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.
