Treatment of a retained lens fragment depends on the location of the fragment, the presence of corneal edema, the degree of inflammation, and the effect on intraocular pressure (IOP).
Dislocated or decentered intraocular lenses (IOLs) have various surgical options for correction.
Opacification of the posterior capsule occurs frequently after cataract surgery; it can appear months to years after cataract surgery and is commonly treated with Nd:YAG capsulotomy.
Toxic anterior segment syndrome is a sterile inflammation that is caused by toxic substances such as residue on instruments and may mimic endophthalmitis.
Despite numerous studies showing a reduced incidence of endophthalmitis with the use of intracameral antibiotics at the completion of cataract surgery, no antibiotics are currently approved by the US Food and Drug Administration for this indication.
Cystoid macular edema (CME) is a common cause of decreased vision that occurs weeks to months following cataract extraction. It is associated with increased perifoveal capillary permeability and accumulation of fluid in the inner nuclear and outer plexiform layers of the retina.
