What it is
Laser retinopexy is a laser treatment for selected retinal tears or breaks. Laser spots are placed around the tear, creating an adhesion that holds the retina firmly to the tissue beneath it. This helps seal the tear and reduces the risk of it progressing to a retinal detachment.
Who it's for
People with a retinal tear or break found on examination — often after sudden new floaters or flashes of light — usually before the retina has detached, as advised by the doctor. Seek care the same day if you notice these symptoms.
What to expect
Your pupil is dilated with drops and the eye is numbed. The laser is applied through a special contact lens at the slit-lamp, or with an indirect ophthalmoscope (LIO) for tears at the far edges of the retina. You will see bright flashes of light, and the treatment takes a few minutes.
Recovery
Vision may be blurred for a few hours, so come with someone who can take you home. The laser adhesion takes about two weeks to become firm, so your doctor may advise avoiding strenuous activity during this time. Seek care the same day if you notice more floaters, new flashes or a shadow in your vision.
Frequently asked questions
Does laser retinopexy prevent retinal detachment?
It lowers the risk by sealing the tear, but it cannot remove the risk completely. Report any new floaters, flashes or a shadow in your vision straight away.
Is it done the same day?
Often yes. A retinal tear is usually treated promptly, frequently on the day it is found.
