Sharp-edged intraocular lens design as a cause of permanent glare.

摘要

PURPOSE: To evaluate patients who had implantation of an acrylic intraocular lens (IOL) and reported edge glare that did not lessen with time. SETTING: Hawthorn Eye Clinic, Kew, Victoria, Australia. METHOD: This retrospective study comprised patients who had uneventful phacoemulsification and then reported glare that did not abate after 12 months. RESULTS: Five patients (7 of 322 eyes; 2.2%) who received an AcrySof MA30BA IOL with a 5.5 mm optic and 1 patient (1 of 221 eyes; 0.5%) who received an AcrySof MA60BM IOL with a 6.0 mm optic reported permanent edge glare. Extensive retinal and neurological evaluations in 2 patients showed no deficits in 1 and an abnormal photopic red electroretinogram in the other. Pilocarpine 1% was used in 3 patients and gave no relief of symptoms. Two patients (3 eyes) had IOL explantation with complete resolution of glare symptoms. There was no statistical significance between the 2 types of IOLs. CONCLUSION: Sharp-edged IOL designs can cause permanent intractable glare.
