Abstract

PURPOSE
We studied the clinical products of sulcus fixation of Black-diaphragm intraocular lens and transscleral fixation of Black-diaphragm intraocular lens in congenital and acquired aniridia patients. METHODS: We retrospectively analyzed the records of 12 aniridic eyes in 20 patients who underwent Black-diaphragm intraocular lens implantation from December 2001 to December 2003 at our hospital. We divided the aniridia eyes into sulcus fixation (group 1, 3 eyes of 3 patients) and transscleral fixation (group 2, 8 eyes of 8 patients) groups, and congenital aniridia (group A, 3 eyes of 3 patients) and acquired anirida (group B, 9 eyes of 9 patients) groups. We compared results between groups 1 and 2, and between groups A and B. RESULTS: The differences (in diopter) between preoperatively expected refractive error and postoperative refractive error were -1.27 +/- 1.06 in group 1 and -1.06 +/- 1.06 in group 2, and this difference between groups 1 and 2 was not significant. Postoperative visual acuity results in group A (0.18 +/- 0.03) were significantly better than those in group B (0.61 +/- 0.29). CONCLUSIONS: In Black-diaphragm intraocular lens implantation of aniridia patients, the differences between preoperatively expected refractive error and postoperative refractive error were not different between sulcus fixation and transscleral fixation. Better postoperative visual acuity results are anticipated in acquired aniridia patients than in congenital aniridia patients.
