LASIK is most widely known laser surgery for the 2nd generation. It is part of one of those 3 types of cornea laser treatment that is surgical on the refractive errors. It had gained popularity for which it corrected myopia or nearsightedness, astigmatism and hyperopia or farsightedness. The correction is made for the visual errors by making a flap that is thin and by folding back gently that surface of cornea to undergo second laser. The second laser can reshape cornea. After which post operation care is required like eye drops and goggles.
Risks & Complications – Here comes the real problem of few risks and complications involved in LASIK if not taken proper care in post surgery. One important thing a patient should always remember is that LASIK is one of those treatments to correct the refractive errors with respect to vision of the eye and it is not an assurance of permanent solution. So there needs to be taken a lot of care to maintain the correction made.
Risks – Few people have the habit of using contact lens and most doctors say a big NO to contact lens before getting operated under LASIK. The reason is it has the power of causing infection and chances are there with few contact lens, vision can be at risk. So, when doctor says NO to contact lens before surgery and after that – It is simply a NO! Aberrations can occur at higher order and those cannot be rectified by using spectacles or any kinds of glasses. For many people, this type of problem occurs if their reshaped cornea and the original one. All this states to select a right patient! Not everyone can undergo smile LASIK.
Dry eyes are very common for many patients after surgery and last only temporary, say for couple of weeks to 2 months. But, for few it can turn into a syndrome called dry eye. It can be treated by prescribing artificial tears and through a method of punctal occlusion. Even after all these treatments if it lasts, it means one have to live with it. Halos is another risk after the surgery when few say that they are seeing ghosts, starburst etc but that is only during night because pupil size expands at night and contracts during the day.
Complications – The complications related to flap can occur like slipping, displacement, folding of flap, retinal detachment, Uveitis are to name a few. All these complications and risks can start at any stage like pre operation, during, after and later operation too.
