Given below are the risks which are involved in LASIK eye surgery:
Under corrections – If too little tissue is removed from the eye by the laser then the vision will not be as clear as you were wishing for. This problem is more common with nearsighted people and another refractive surgery may be needed within a year to rectify the problem and remove more tissues.
Over corrections – There is always a possibility that the laser will remove extra tissue from the eye. It is more difficult to rectify over corrections than under corrections.
Astigmatism – This condition can be caused due to uneven removal of tissue and additional surgery may be required.
Loss of vision – It is rare but you may lose vision due to complications in the surgery. Sometimes it may happen that the patient will not be able to see as clearly and sharply as before.
Returning to pre-surgery vision – Over a period of time, the eyes may revert to the previous level of vision due to hormonal imbalance, abnormal wound healing or pregnancy.
Double vision, halos and glare – You may experience difficulty in seeing objects in the night as you may notice double vision, glare or halos around bright lights.
Dry eyes – There is temporary decrease in the production of tears after Lasik due to which the eyes feel dry and it can reduce the quality of your vision.
Flap problems – Complications such as excess tears, infections and inflammations are caused because of removing or folding back the flap during the surgery from the front of the eye.
