Is blurry vision normal after retinal detachment surgery?

What's normal

AAO's retinal detachment guidance says vision improvement typically begins 4 to 6 weeks after surgery, though complete stabilization may take months. Blurriness through that stretch is the norm, not a sign that something failed.

If a gas bubble was used, the bubble itself blurs everything until it absorbs. StatPearls reports air lasting about 5 to 7 days, SF6 about 1 to 2 weeks, and C3F8 about 6 to 8 weeks, so the clearing schedule depends on which gas you received.

After a scleral buckle, the shape of the eye changes slightly and your glasses may simply be wrong. StatPearls describes surgery-induced myopic shift and astigmatism as documented effects of buckling, with astigmatism linked mainly to radial elements and myopic shift to circumferential elements. New glasses usually wait until the eye is stable.

StatPearls also notes that after buckle surgery, fluid under the retina can persist for up to 3 months even when all breaks are closed, and such cases can be observed safely. That can keep vision hazy longer than expected.

Typically blurry through the first month, with improvement often beginning around week 4 to 6 and months to settle.

When it stops being normal

Steady, gradual improvement is the pattern to expect. Vision that suddenly worsens after improving, a new gray curtain or shadow, or blurring alongside increasing pain needs an urgent call. AAO lists a gray curtain over the vision and a shadow in peripheral vision as reasons to seek immediate care.
