Dry Eyes:

In some cases, individuals have complained of decreased tear production resulting in eye irritation and vision blurring. Nearly half of laser eye surgery patients experience dry eye syndrome of varying levels. Dry eye syndrome is majorly corrected by application of lubricating eye drops to the surface of the eyes.

Eye Infection:

Although rare, laser eye surgery may lead to eye infections. This risk can be reduced by creating more sterile conditions by using a natural bandage after surgery.
