The largest single problem in cataract surgery today is related to complications induced by postoperative morphologic changes in the vitreous. These include persistent corneal edema, macular disturbance, pupillary block, and detachment of the retina.
To obtain a better picture of the changes which occur in the vitreous body following cataract surgery, a careful postoperative study of 1,058 eyes was undertaken. All patients were from our private practice.
After intracapsular lens extraction, the anterior hyaloid membrane, at the level of the patellar fossa, loses its support (lens and zonule). Previously concave, it is now convex. However, there are cases where the membrane remains behind the level of the iris retaining a posterior chamber of sorts.
The membrane has the appearance of an opalescent sheet on whose surface are found pigment deposits and small white spots derived from organization of exudate. The latter are the residues of the slight inflammatory reactions accompanying
