Three-piece intraocular lens in the sulcus with optic capture in patients with mild to moderate zonular weakness in exfoliation.

PURPOSE

To study the use of sulcus placement of a 3-piece intraocular lens (IOL) with optic capture in patients with exfoliation with zonular weakness.

METHODS

Data on all exfoliation patients who had direct or indirect evidence of zonular weakness and had a 3-piece IOL implanted in the sulcus with optic capture over a 5-year period between January 2017 and January 2022 were included in this retrospective case series.

RESULTS

The study comprised of 35 eyes of 35 patients. The mean age at surgery of the 20 male and 13 female patients was 75.21 years ± 5.74 (standard deviation (SD)). The mean pupillary diameter was 5.77 ± 2.23 mm (range: 10 to 3 mm). A capsular tension ring (CTR) was used in 17 cases and iris hooks as a pupil-expanding device were used in 15 cases. No patients had an increase in inflammation after surgery and there were no late subluxation or dislocation of "in the bag" posterior chamber IOL or major complications. There was a significant improvement in visual acuity.

CONCLUSION

The sulcus placement of 3-piece IOL with optic capture is the ideal technique in patients with clinical or intraoperative evidence of mild to moderate zonular weakness. It may also be more appropriate in relatively younger patients (in the fifties or sixties) with exfoliation with no overt zonulopathy to prevent late subluxation or dislocation of "in the bag" IOL.
