Second-generation capsular anchor for subluxated lenses: first clinical results.

PURPOSE: To evaluate the use of the second-generation capsular anchor in the treatment of subluxated crystalline and synthetic intraocular lenses.

SETTING

Department of Ophthalmology, Meir Medical Center, Kfar Saba, Israel.

DESIGN

Prospective interventional study.

METHODS

This study evaluated the second-generation capsular anchor, a 3D poly(methyl methacrylate) intraocular implant designed to anchor the lens capsule to the sclera. All surgeries were performed by a single surgeon. Intraoperative and postoperative complications were recorded. Corrected distance visual acuity, lens centration, and lens tilt were assessed at the final follow-up of 3 months.

RESULTS

10 eyes of 10 patients were included in this study. Mean age was 56.2 (22 to 87) years. The reasons for the lack of zonular support were pseudoexfoliation in 3 cases, trauma in 3 cases, and Marfan, ectopia lentis, and pathologic myopia (1 case each). In 1 case, pseudoexfoliation and a history of recent trauma coexisted. 8 of the 10 surgeries were due to subluxation of crystalline lenses and 2 due to subluxation of intraocular lenses. Vision improved in all patients after surgery. Centration of the IOLs was excellent in all patients at the third postoperative month. One patient developed a retinal detachment at the third postoperative week and underwent successful surgery, and 1 patient developed macular edema at the fifth postoperative month, which resolved with topical medication.

CONCLUSIONS

The second-generation capsular anchor, designed to provide significant improvements over the first-generation device, is effective in fixating the capsular bag to the scleral wall in cases with inadequate capsular support.
