Abstract

PURPOSE. To report an exchange technique for opacified hydrophilic acrylic intraocular lenses (IOLs). METHODS. Twenty patients with two different types of opacified hydrophilic acrylic IOLs underwent IOL exchange by a single surgeon. Circumferential enlargement of the pre-existing capsulorrhexis was a critical step of the procedure, and resulted in expression of the IOL with minimal traction to the capsule. Implantation of an in-the-sulcus IOL followed. Surgical technique, complications, and visual outcome are discussed. RESULTS. Time from the initial cataract operation varied from 15 to 61 months (mean 30.5), and in all cases marked fibrosis was encountered. Eighteen patients had uncomplicated IOL exchange. Posterior capsule rupture occurred in two cases. Vision improved in 16 cases, remained unchanged in 3 cases, and deteriorated in 1 case. CONCLUSIONS. IOL exchange of opacified hydrophilic acrylic IOLs is a particularly challenging procedure due to extensive fibrosis. Circumferential enlargement of the pre-existing capsulorrhexis significantly facilitates the mobilization of the IOL from its fibrous pocket, with the use of minimal forces. Thus, the risk of zonular dehiscence or posterior capsule rupture is minimized.
