Pigment dispersion with elevated intraocular pressure after AcrySof intraocular lens implantation in the ciliary sulcus
Wintle R; Austin MJournal of Cataract and Refractive Surgery 2001; 27: 642-644
A 45-year-old white woman had phacoemulsification with intraocular lens (IOL) implantation. The surgery was routine except for a linear tear in the posterior capsule; there was no disruption of the anterior vitreous face. After residual soft lens matter was removed, an AcrySol® IOL was placed in the ciliary sulcus. One month postoperatively, the patient presented with an intraocular pressure (IOP) of 30 mmHg and signs of pigment dispersion with 360° of heavy pigmentation of the trabecular meshwork and iris transillumination defects. IOP was controlled with a topical beta-blocker. The optic disc appearance and visual field remained normal, but the uniocular hyperpigmentation of the trabecular meshwork was still present. The authors hypothesize that the sharp square edge of the ArcySof IOL increases the risk of a chafing effect on the posterior iris pigment, and advocate that this IOL be placed in the capsular bag and ideally have 360° of protective overlapping of the anterior capsule over the edge of the optic.
