I had a cataract surgery on both eyes. I have severe flashes on one eye during night time driving.
What is the cause and what is the cure?
Thanks for your Question
Eye flashes after cataract surgery can occur especially if the cataract surgery was complicated one with vitreous loss during the surgery.
The barrier between the cataract and the vitreous body in the eye is called the capsule. Sometimes during cataract surgery, this capsule is ruptured and vitreous starts to move from the back of the eye to the front part of the eye through this rupture.
This vitreous should be removed during the surgery. Any remnants of the vitreous in the front part of the eye can cause several complications. Vitreous is attached to the interior surface of the retina.When the vitreous is moved it can pull the retina with it which is manifested as flashes of light.
Sometimes, complete detachment of the vitreous from the retina can occur, which is a good thing but sometimes, this traction on the retina can cause retinal tears or holes or retinal detachment which is a bad thing.
I would recommend that you visit your eye doctor to have a full ocular and fundus exam and to rule out any vitreous in the anterior chamber and any traction on the retina.
