Results of a retrospective, comparative case study showed similar outcomes for same-day pars plana vitrectomy compared with delayed pars plana vitrectomy.
"The risks and benefits related to the timing of vitrectomy after a complicated cataract surgery should be carefully discussed with each patient," the study authors said.
Researchers evaluated the visual outcomes and ocular morbidity of 172 eyes of 171 patients with retained lens fragments after complicated cataract surgery. Average age was 75 years. The mean time to vitrectomy for the delayed group was 15 days, according to the study.
Patients underwent three-port (20-, 23-, or 25-gauge instrumentation) pars plana vitrectomy between 2005 and 2008.
Of 59 eyes that had immediate vitrectomy, 17 experienced postoperative complications; 38 of 113 eyes undergoing delayed vitrectomy experienced complications. The difference was not statistically significant (P = .61). Cystoid macular edema, the most common complication, occurred in 25 patients.
Results showed that preop logMAR best corrected visual acuity for immediate vitrectomy was 0.73 compared with 0.72 for delayed vitrectomy. Six-month logMAR visual acuity was 0.44 for same-day vitrectomy, compared with 0.44 for delayed vitrectomy.
Additional research is needed to help establish the best time for surgical planning, the researchers concluded.
