Capsulorhexis, phacoemulsification, and posterior chamber lens placement following iridocyclectomy.
Two patients developed cataract following iridocyclectomy for iris melanoma invading the angle. Although several clock hours of zonular fibers had been surgically resected, the use of a continuous, circular capsulorhexis followed by phacoemulsification maintained the integrity of the anterior capsular margin and allowed for stable "in-the-bag" placement of a posterior chamber intraocular lens (PC-IOL). Continuous, circular capsulorhexis is the optimal anterior capsulectomy procedure, minimizing the incidence of radial tears and the risk of subsequent PC-IOL decentration.
