Expansile loops for anterior chamber lens implants.

Twenty eyes undergoing pars plana lensectomy with insertion of expansile loop anterior chamber lens implants were followed for 4-11 months. Sixteen eyes received a Simcoe lens, and all achieved a visual acuity of 20/20-20/40 without complications. Two of three eyes with Shearing implants developed uveitis an cystoid maculopathy. The one Sinsky implant tilted and required replacement. Highly flexible expansile implants (i.e., Simcoe lens) appear to be well tolerated in the anterior chamber and achieved excellent stability. The observation period was too short to draw definite conclusions. This study will be continued.
