|Risks of complications for iridotomy are low, but some individuals may experience increased intraocular pressure immediately after surgery. Usually, the high IOP resolves within a few weeks. Rarely, individuals will develop cataracts as a result of laser surgery. Other complications include inflammation (iritis), abnormal growth of vessels (neovascularization), bleeding (hyphema), or infection.|
A primary complication of iridectomy is failure of the incision to close properly. Other possible complications common to most eye surgeries include bleeding (hyphema), inflammation, infection of the iris (iritis), abnormal vessel growth (neovascularization), loss of too much fluid causing flattening of the eye, worsening of cataracts, swelling of the clear, outer layer of the eye (cornea), and permanent worsening of underlying glaucoma. These complications can result in permanent vision loss.
With both types of procedures, individuals who have had previous eye surgery have a higher risk of failure.
