Are floaters normal after YAG laser capsulotomy?

What's normal

The laser breaks up the cloudy capsule, and small fragments can drift into the clear gel that fills the eye. Those fragments cast shadows on the retina, which you see as specks, threads, or cobwebs. An AAO ophthalmologist answering this exact question writes that you may notice some floaters in the first week after the procedure and that this is also normal, and that a capsulotomy rarely leaves you with long-term significant floaters.

Typical post-YAG floaters are a handful of drifting shapes that move when you move your eye, are worst against a bright white page or a blank wall, and gradually stop registering. There is no fixed timetable for them to go away, and many people simply stop noticing them. They should not come with pain, and they should not block a section of your vision.

Usually noticed within the first day or two and less bothersome over the following weeks, per AAO patient guidance.

When it stops being normal

The pattern that matters is different from a few drifting specks. Call your ophthalmologist the same day if you suddenly notice many new floaters at once, see flashing lights, notice a shadow in your peripheral vision, or see a gray curtain covering part of your field of vision. The AAO lists exactly those as signs of a detached retina and says a detached retina has to be examined by an ophthalmologist right away or you could lose vision in that eye.

Retinal detachment after this laser is uncommon. The AAO's clinical guidance for the procedure gives a reported range of roughly 0.08 to 3.6 percent of eyes, and a large Finnish study of 17,688 eyes published in Acta Ophthalmologica found no association between YAG capsulotomy and later detachment. Uncommon still means worth a same-day exam, because detachment is treatable when it is caught early.
