- W2039203400 abstract "In Brief Purpose: To develop a technique for documenting and quantifying capsule bend formation in pseudophakic eyes, evaluate when the anterior and posterior lens capsules become completely apposed to the optic, and determine how soon a capsule bend is created at the optic edge of an intraocular lens (IOL) after cataract surgery. Setting: Medical University of Vienna, Department of Ophthalmology, Vienna, Austria. Methods: This prospective study comprised 33 eyes of 33 patients with age-related cataract who were scheduled to have cataract surgery. All eyes had phacoemulsification with implantation of 1 of 3 types of open-loop IOLs: 1-piece acrylic (SA60AT, Alcon), 3-piece acrylic (AcrySof MA60BM, Alcon), or 3-piece silicone (911A, AMO). Each group included 11 eyes. One and 3 days and 1, 2, 3, and 4 weeks after surgery, contact between the lens capsule and IOL optic as well as capsule bend formation were evaluated using optical coherence tomography (OCT). The postoperative times at which the capsule came into contact with the IOL optic and when the capsule bend formed were determined. Results: One day postoperatively, the mean distance between the anterior capsule and the IOL was 197 μm in the 1-piece acrylic IOL group, 161 μm in the 3-piece acrylic IOL group, and 220 μm in the 3-piece silicone IOL group. The posterior capsule was in contact with the IOL on the same day or earlier than the anterior capsule in 28 patients (85%). Postoperatively, the capsule bend formed at a mean of 10 days in the 1-piece acrylic group, 13 days in the 3-piece acrylic group, and 15 days in the 3-piece silicone group. The short-term reproducibility of the OCT technique was excellent (r = 0.99). Conclusions: Optical coherence tomography produced cross-sectional tomograms of capsule–IOL contact in the early postoperative period. There was no significant difference in the time to capsule bend formation between the 3 IOLs. However, capsule bend formation at the optic edge occurred earlier with the 1-piece acrylic IOL than with the 3-piece silicone IOL. Assessment by OCT technology showed that capsule closure and capsule bend formation at the IOL optic edge were similar with 3 types of open-loop IOLs." @default.
