To the Editor.  —We have analyzed 1122 surgically removed intraocular lenses (IOLs) from complicated cases and enucleated globes containing IOLs that were submitted to the Center for Intraocular Lens Research, University of Utah Health Sciences Center, Salt Lake City, over a period of nearly four years (late 1982 to October 1986). These specimens were obtained from ophthalmologists nationwide and were sent to us without solicitation. Therefore, our series does not have any known geographic bias that might have skewed the random nature of the study. Only 8% of the lenses were submitted by the implant surgeon; 92% were removed by a consulting physician and were either sent directly to us or were forwarded to us by the American Society of Cataract and Refractive Surgery, Fairfax, Va.See also p 52.Most of these IOLs were removed because of such ocular complications as uveitis, pseudophakic bullous keratopathy, cystoid macular edema, secondary
