Opacification of the posterior capsule occurs most commonly from Elschnig pearl migration or fibrosis. The physical contact of a posterior chamber lens, particularly one with a reverse optic, has been postulated to decrease the rate of capsular opacification by creating a barrier to Elschnig pearl migration. This randomized prospective clinical study comparing the 3M style 34S convex-plano optic and style 34R plano-convex (reverse) optic posterior chamber lens demonstrated a statistically significant reduction in capsular opacification by Elschnig pearls at one year in the reverse optic lenses (18.2% versus 7.6%, P = .03). No statistically significant difference in capsular fibrosis rates was noted (2.5% versus 4.5%, P = .48). The reverse optic implant also demonstrated greater iris to implant optic clearance.

Neodymium:YAG laser intraocular lens damage results in opacities in the pseudophakos. When located in the visual axis, these opacities may cause glare and image degradation. In this paper, we report a patient who experienced disabling glare sufficient to require the explanation of the YAG-damaged intraocular lens. The patient, her management and clinical course, and the pathology of the explanted lens are discussed.

Excimer laser PARK successfully corrected low and moderate myopia combined with up to 4.0 D of astigmatism with a low mean angle of error. To increase the accuracy of toric ablation, specific algorithms for the cylinder component are needed.
