Abstract
PurposeTo find the incidence, contributing factors, outcomes, and clinical impact of intraoperative posterior capsule striae. SettingIladevi Cataract & IOL Research Centre, Ahmedabad, India. MethodsIn a prospective study, 100 consecutive eyes had phacoemulsification and intraocular lens (IOL) (AcrySof® MA30BA) implantation. The presence of striae was noted at the end of the operation, and factors contributing to their development were identified. Follow-up was done at regular intervals, and the clinical impact of striae on patients’ vision was evaluated. ResultsStriae were observed in 56 eyes (Group 1) but were absent in 44 (Group 2). Mean age in Group 1 was 65.96 years ± 9.15 (SD) and in Group 2, 59.20 ± 10.36 years (P = .0012). Mean axial lengths were 23.47 ± 1.63 and 24.12 ± 1.49 mm, respectively (P = .0419). Average lens thickness was greater in Group 1 (4.50 ± 0.43 mm) than in Group 2 (4.13 ± 0.41 mm) (P = .0001). The sex of patient, capsulorhexis size and centration, grade of cataract hardness, scleral rigidity, and IOL centration were not found to contribute to striae development. The striae disappeared by 5 months postoperatively and did not show a positive Maddox rod phenomenon. ConclusionIntraoperative striae observed in many patients were associated with relatively older age, greater lens thickness, and shorter axial length. The striae eventually disappeared and had no effect on vision.
