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.
