Sealing Tears Before They Detach
['\nWhen examination finds a retinal tear (usually after a posterior vitreous detachment), a ring of laser burns is placed around it. The treated area scars over one to two weeks, sticking the retina down and walling off the tear so vitreous fluid cannot seep behind the retina. The procedure is done in clinic: dilated eye, anaesthetic drop, contact lens, and a series of bright flashes over a few minutes.
\nUntil the scar matures, the tear can still leak — so activity limits are advised for the first week or two, and any new shower of floaters, flashes or shadow means immediate re-examination. Not every finding needs laser; small at-risk lesions are sometimes observed. The judgement call — treat versus watch — is exactly what a dilated retinal examination provides, and it should happen promptly after new symptoms.
\n']Common questions
Does laser retinopexy hurt?
Most feel flashes and mild awareness; pain is uncommon and brief.
How long does the scar take to form?
About one to two weeks — the reason for short-term activity caution and awareness of warning signs.
Can I exercise after?
Light activity is fine quickly; strenuous exercise is limited for roughly two weeks or as your specialist advises.
Will I still have floaters?
Existing floaters may persist; new symptoms, however, always warrant review.
Is one session always enough?
Usually, but extensive or new tears can need supplementary treatment at follow-up.
