Subluxated cataract lens surgery using sutured segments or rings and implantation of toric intraocular lenses.

PURPOSE: To evaluate the intraoperative performance and postoperative outcomes of toric intraocular lens (IOL) with suture ring implantation in adult patients with subluxated lenses.

SETTING: Department of Ophthalmology, Kaiser Permanente, Santa Clara, California, and the Eye Institute of Utah, Salt Lake City, Utah, USA.

DESIGN: Retrospective case review.

METHODS: Eyes with subluxated cataractous lenses and preoperative corneal astigmatism having toric IOL implantation with a sutured ring or segment were studied. Preoperative and postoperative analyses included uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and cylindrical power postoperatively and 3, 6, and 12 months postoperatively.

RESULTS: Twenty-one eyes of 15 patients were studied. The median follow-up was 14.6 months. The mean CDVA at the final follow-up (0.10 logMAR ± 0.15 [SD]) was significantly improved from the mean preoperative CDVA (0.73 ± 0.40 logMAR). Postoperative cylindrical power was significantly improved in all patients (mean reduction in astigmatism 2.37 ± 1.46 diopters). Patients who required postoperative enhancement had anterior laser capsulotomy for bilateral capsule phimosis (2 eyes), photorefractive keratectomy (1 eye), pupilloplasty (1 eye), and posterior laser capsulotomy (2 eyes).

CONCLUSION: Cataract removal and implantation of a toric IOL combined with a sutured ring or segment capsule stabilizing device was a safe and efficacious long-term solution for patients with subluxated cataract lenses and corneal astigmatism.
