Detachment of the retina is another rare major complication. Retinal detachment is when the inner layer of the retina separates from its outer layer. This is usually the result of a hole or break in the inner layer that allows fluid in between the two layers. It is estimated for retinal detachments to occur in less than 1 out of 1000 patients.
A less severe complication is a retinal tear, or break. However, a retinal tear often results in eventual retinal detachment.
If you are at high risk for a retinal detachment prior to the procedure, your doctor may recommend special retinal examinations or may recommend treating your eye with a laser prior to LASIK to reduce this risk.
If a retinal detachment does develop, the method used to treat a detachment depends on its severity and location. Most will involve a surgery to attempt to repair the damage. The effects of this problem will also range from no vision loss to total vision loss.
If this rare complication does occur, you doctor will discuss the treatment options in your particular situation and the possible consequences of this complication.
