A Clinical Study on Transscleral Fixation of Posterior Chamber Intraocular Lens in Complete Vitrectomized Eyes

ABSTRACT

PURPOSE: We studied the result and cilincal significance of transscleral fixation of posterior chamber lens in complete vitrectomized eyes without capsular support. METHODS: We evaluated 30 aphakic eyes of 30 patients and according to the cause of pars plana vitrectomy, there were 9 eyes for intraocular foreign body, 8 eyes for lens dislocation, 8 eyes for retinal detachment, 3 eyes for vitreous hemorrhage, 2 eyes for endophthalmitis. RESULTS: The postoperative best-corrected visual acuity group was intraocular foreign body group and the group of lens dislocation, vitreous hemorrhage, retinal detachment, and endophthalmitis were in the descending order of visual acuity. The most common postoperative early complication was temporary hypotony and the others were hyphema, and temporary increased IOP. The most common postoperative late complication was exposed scleral fixation suture and the others were vitreous hemorrhage, cystoid macular edema, subluxation of intraocular lenses, retinal detachment. CONCLUSIONS: We experienced many postoperative temporary hypotony patients, but all cases were improved in short term period. The complication related to scleral fixation in vitrectomized eyes was imposed to smaller than the scleral fixation in vitreous support. But, in fact the development of retinal detachment or vitreous incarceration complication in the vitrectomized eye was not different from the eyes having vitreous support.
