Cataract extraction significantly improved vision and function in a majority of patients with retinitis pigmentosa, according to a study.

The retrospective, observational case series included 80 eyes of 47 patients with retinitis pigmentosa (RP) who underwent cataract surgery. Mean patient age was 48.9 years. Patients were followed for a mean 23.3 months.

Posterior subcapsular cataracts were reported in 97.5% of patients, the study authors said.

By 3 months postoperative, mean best corrected visual acuity improved from 20/340 to 20/129; the gain was statistically significant (P < .0001).

Preoperative vision improved from a mean of 20/81 to 20/43 postoperatively, which was also statistically significant (P < .0001).

Sixty-six eyes experienced posterior capsule opacificationm, and 42 eyes underwent YAG laser capsulotomy at a mean of 10.8 months following surgery.

Fifteen eyes of 10 patients showed signs of phacodonesis. Bilateral dislocated in-the-bag IOLs occurred in one patient at 5.5 years and 6 years postoperatively.
