Phaco, phacotrabeculectomy have similar long-term PCO rates
DETROIT No significant differences were found in the incidence of long-term posterior capsular opacification between phacoemulsification and phacotrabeculectomy, a study here found. Use of mitomycin C adjunctively was a protective factor against PCO in the phacotrabeculectomy group, as was the presence of diabetes mellitus in the overall patient group, the study authors said.
Researchers here retrospectively studied 100 eyes of 100 patients with cataracts who underwent phaco and posterior chamber IOL implantation and 100 eyes of 100 primary open-angle glaucoma patients with cataract who underwent phacotrabeculectomy and posterior chamber IOL implantation.
No significant difference in the rate of PCO requiring Nd:YAG capsulotomy was found between the phaco and phacotrabeculectomy groups. However, a significant difference in the rate of PCO was found between patients without diabetes mellitus and those diagnosed with the disease preoperatively (P = .016). A survival analysis showed patients in the phacotrab group who received mitomycin C had a higher survival rate than those who did not (P = .03).
The study is published in the American Journal of Ophthalmology.
