Floaters in Eyes After PRK, Why is This?

If you are having new floaters then you should see your ophthalmologist as soon as possible for a full dilated retinal exam. Floaters can be a symptom of retinal tear or detachment and thus should be diagnosed and treated quickly. Nearsightedness, which is the most common indication for laser vision correction, is also a common risk factor for floaters.

Anything is possible but floaters are not expected to change for the better or the worse with PRK. However most PRK is done for myopia (nearsightedness) and nearsighted individuals get more floaters. Your experience may be due more to your nearsightedness. Recent studies have reconfirmed that LASIK and PRK does not result in increased vitreo-retinal events such as retinal detachments.

While the PRK wasn't the cause of your floaters (that is caused by a degeneration in the jelly of the eye called the vitreous), it is frequently noted by patients after both PRK (and LASIK) that they seem to see their floaters more commonly.   More intensely noticing everything about the eyes after surgery is normal and common, it is the most likely reason for your symptoms.  Floaters are noticed most frequently while looking at a distance, in the sky or at a light background. 

Having said that, it is important to note that if a large increase in floaters occurs, or you see flashes of light or a curtain/vail appearing in the visual field, that could be a coincident problem of a retinal tear requiring an urgent visit to the Retinal specialist.

In very rare cases after LASIK, the retina may develop a tear and the vitreous can become more filled with floaters, but not after PRK...     if this were to occur after LASIK, an emergent visit to a Retina specialst would be warranted.
