Relative factor analysis of macula hole retinal detachment after phacoemulsification cataract extraction combined with intraocular lens implantation

Abstract

Objective To observe the incidence and related factors of macula hole retinal detachment (MHRD)after phacoemulsification cataract extraction and intraocular lens(IOL) implantation. Methods The clinical data of 10 076 patients (13 625 eyes) who underwent phacoemulsification cataract extraction and intraocular lens implantation were retrospectively analyzed. There are 1228 patients (1853 eyes) with high myopia. All the patients were examined by routine slit-lamp microscopy, ophthalmoscopy as well as A-or B-scan ultrasonography. The phacoemulsification cataract extraction with transparent cornea incision or scleral tunnel incision, combined with intraocular lens implantation was performed in all the patients. The follow-up was ranged from 12 to 126 months, with a mean of (48.2±31.1) months. The MHRD was confirmed by the examinations of the fundus, B-scan ultrasonography and optical coherence tomography.The incidence of postoperative MHRD and the risk factors were analyzed. Results 10/13 625 eyes (0.073%) with MHRD were observed. 7/1853 high myopia eyes (0.378%) with MHRD were observed.The occurrence time of MHRD was ranged from 9 to 74 months after surgery, with a mean of 38.5 months.The cumulative risk was estimated at 0.16% (95% confidence interval, 0.05%-0.27%). Conclusions The incidence of MHRD after phacoemulsification cataract extraction combined with intraocular lens implantation is 0.073%. The MHRD incidence of high myopia eyes is 0.378%. High myopia may be the risk factor for MHRD. Key words: Retinal detachment/etiology; Phacoemulsification; Phakic intraocular lenses
