Comprehensive approach for capsular bag fixation in subluxated crystalline lens: preserving the anterior/posterior anatomical segment barrier.

PURPOSE: To report the intraoperative performance and postoperative outcomes of crystalline lens removal and in-the-bag intraocular lens (IOL) implantation with scleral-bag fixation by means of capsular tension segments (CTSs) and a capsular tension ring (CTR) in patients with a subluxated lens.

SETTING

Department of Ophthalmology, Shaare-Zedek Medical Center, Jerusalem, Israel.

DESIGN

Retrospective, consecutive case series.

METHODS

This study included patients with subluxated crystalline lens who underwent lensectomy or cataract extraction using an anterior chamber maintainer (ACM), a CTR, transscleral capsular-bag fixation by polytetrafluoroethylene suture with 2 CTSs, and in-the-bag IOL implantation. Outcome measures included intra- and postoperative complications, corrected distance visual acuity (CDVA), target and postoperative refraction, and IOL tilt.

RESULTS

17 eyes (9 patients) were included, with a mean follow-up of 22.06 ± 14.88 months. There was a significant improvement in mean logMAR CDVA ( P < .001), with 15 eyes (88.24%) achieving a Snellen CDVA of 20/30 or better and all eyes achieving 20/40 or better. The mean refractive spherical-equivalent prediction error was 0.07 ± 1.10 diopters (D), with 10 (58.82%) and 15 (88.24%) of eyes within ±0.50 D and 1.00 D, respectively, from the intended refraction. The mean horizontal and vertical tilts were 1.9 ± 2.6 degrees and 2.6 ± 2.1 degrees, respectively. No complications were observed except for 1 case of an intraoperative posterior-capsular tear.

CONCLUSIONS

A comprehensive surgical approach for scleral-bag fixation that combines the use of an ACM, CTR, polytetrafluoroethylene sutures, 2 CTSs with in-the-bag IOL implantation, offers an effective strategy for achieving favorable visual outcomes and a low incidence of complications in patients with subluxated crystalline lenses.
