Antibodies to lens crystallins after endocapsular cataract surgery

ABSTRACT

Levels of serum antibodies against lens alpha, beta H and beta L crystallins were determined in 15 patients before and after endocapsular cataract extraction. The most abundant antibody at the time of surgery was anti-beta L, followed by anti-beta H and anti-alpha. An increase in the basal levels of these antibodies was seen after surgery in 93 percent of the cases. Relative increase was highest for anti-alpha, followed by anti-beta H and anti-beta L. There were individual variations both in the shape of the time-dependent antibody response after surgery and in the relative intensity of the response to the different antigens. The endocapsular technique therefore leads to the release of crystallins into the anterior chamber in sufficient amounts to provoke in many patients a humoral immune response
