LASIK is a surgical procedure using lasers that aim to correct common vision-related problems. This is an extremely safe out-patient procedure with about 98% success rate. If you are considering LASIK surgery, read ahead to know if this effective procedure is right for you.
What vision problems does LASIK solve?
LASIK is an example of refractive surgery. It corrects common vision problems such as astigmatism, myopia, and hyperopia.
Using lasers, the eye surgeon will make an incision on the tissue that surrounds the cornea. Once the cornea is exposed, the surgeon proceeds to alter the cornea, depending on the vision problem of the patient. For myopic individuals, the precise amount of corneal tissue is removed in order to flatten it and focus the light accurately on the retina. For hyperopic individuals, a steeper angle of the cornea is desired, and the cornea is altered accordingly. For patients with astigmatism, the irregular shape of their cornea is smoothened to correct their vision problem.
LASIK is a highly effective procedure in which most patients achieve 20/20 vision after the surgery. In some cases where 20/20 vision is not achieved, the visual acuity of the patient has still drastically improved compared to their condition before the surgery. These patients are still recommended to wear corrective eyeglasses or contact lenses, but with prescriptions that are much lower than their old one.
When is LASIK not for you?
To know if you are not eligible for LASIK procedures, it is best to visit eye specialists in Singapore and have your eyes checked.
People who changed their eyeglasses prescription in the past year are not qualified for LASIK because the cornea may still be undergoing changes and the resulting shape after the procedure may be inaccurate.
Pregnant and breastfeeding women who want to undergo LASIK procedure are asked to wait until after their pregnancy and nursing period.
Also, people with a lowered ability to heal may experience risks from LASIK surgery. This includes people suffering from rheumatoid arthritis, lupus, diabetes, and HIV. People who are taking medication such as retinoic acid and steroids are also ineligible for this procedure because these chemicals may affect proper wound healing.
