Side effects of laser treatment for a retinal tear

Updated April 08, 2017

Lasers have been used to repair retinal tears and other eye conditions for more than 25 years. Since their inception, the technology has been enhanced to make laser retinal surgery an out-patient procedure with minimal side effects.


After undergoing laser eye surgery to repair a retinal tear, patients have reported blurry vision caused by the calcification of the tissue around the tear.

Light Sensitivity

The laser surgery aftermath includes sensitivity to bright light; due to the trauma of the surgery, the pupil is not able to contract or dilate.

Perception Problems

Using a laser to repair a retinal tear can cause colour-perception errors. While in recovery, the eye will not be able to code correctly the data collected by the pupil and transport it to the brain.

Blind Spot

Even afterwards, some patients who undergo laser eye surgery will have a permanent blind spot.

Decreased Perphirial Vison

While recovering after surgery, the eye's decreased mobility can result in a lessening of both peripheral and side vision.

Decreased Night Vision

Because of lack of pupil expansion, sensitivity to light and decreased night vision can both be side effects of the surgery.
