PURPOSE: To estimate the cumulative incidence of postoperative retinal detachment (RD), rhegmatogenous retinal lesions requiring argon laser treatments, anterior (ACO) and posterior (PCO) capsule opacification, and neodymium:YAG (Nd:YAG) laser capsulotomy in patients with high myopia who had phacoemulsification without intraocular lens (IOL) implantation.
SETTING: Department of Ophthalmology and Neurosurgery, University of Siena, Siena, Italy.
METHODS: Seventy-three eyes of 57 patients with high myopia who had phacoemulsification without IOL implantation from 1993 to 1996 were retrospectively reviewed. The mean postoperative follow-up was 62.3 months and the mean axial length, 30.22 mm (range 29.10 to 33.70 mm). The incidence of RD and preoperative and postoperative prophylactic argon laser photocoagulation for rhegmatogenous retinal lesions were assessed. Between 1997 and 2000, ACO was evaluated subjectively and PCO was evaluated using the EPCO photographic image-analysis system. The incidence of Nd:YAG laser capsulotomy was noted.
RESULTS: Argon laser photocoagulation was performed in 8 eyes (10.9%) preoperatively and 3 eyes (4.1%) postoperatively. One RD (1.3%) was observed 26 months after surgery; no preoperative or postoperative prophylactic argon laser photocoagulation or Nd:YAG laser capsulotomy was performed in this eye. At 1 year, 49 eyes (67.1%) had mild ACO and 24 (32.8%) had anterior capsule fibrosis. The data did not change during subsequent follow-up visits. At 6 years, the mean PCO grade was 1.109 (range 0.972 to 2.931); an Nd:YAG laser capsulotomy was performed in 12 eyes (16.4%).
CONCLUSIONS: Compared with other studies that evaluated the outcomes of highly myopic patients who had cataract surgery with posterior chamber IOL implantation, our patients, who did not have IOL implantation, had a lower incidence of postoperative rhegmatogenous retinal lesions requiring argon laser treatments and a similar incidence of postoperative RD and visually significant PCO.
