PURPOSE: To assess the incidence of pigment precipitates and potential association with glaucoma, diabetes, and/or intraocular lens (IOL) optic center thickness in patients having small incision cataract surgery and foldable IOL implantation.
SETTING: Eye Care Physicians of Michigan, Jackson, Michigan, USA.
METHODS: A retrospective data analysis was conducted of patients with a preoperative diagnosis of glaucoma or diabetes or in whom pigment precipitates had been reported after cataract surgery. Group 1 consisted of 23 patients in whom pigment precipitates had been reported and Group 2, 92 patients in whom no precipitates were reported. Two statistical models were used to analyze preoperative, demographic, surgical, and postoperative variables and determine potential correlations. An overall incidence of the occurrence of pigment precipitates was calculated based on the total number of patients with foldable IOLs.
RESULTS: The incidence of pigment precipitates was 0.35% (n = 23/6519). Mean time to occurrence was 5.5 months. No between-group differences were found in pathologies or other demographics or postoperative variables. Intraocular lens size and implantation correlated with the occurrence of pigment precipitates.
CONCLUSION: The development of pigment precipitates after foldable IOL implantation did not appear to be affected by the presence of glaucoma or diabetes. Newer, slimmer IOL styles and refined insertion techniques were associated with a lower occurrence of precipitates.
