Clinical Study on Anterior Chamber Intraocular Lens Implantation in Completely Vitrectomized Eyes

Purpose: We studied the result and clinical significance of anterior chamber lens implantation in completely vitrectomized eyes without capsular support. Methods: We evaluated 15 aphakic eyes of 15 patients. According to the cause of pars plana vitrectomy, there were 6 eyes for lens dislocation, 5 for intraocular foreign body, and 4 for rhegmatogenous retinal detachment. Results: The final available postoperative best-corrected visual acuity was 0.5 or better in 9 eyes (60%). No statistically significant difference was noted in preoperative and postoperative IOP. The average of postoperative astigmatism was 1.14±0.79D. The most common early complication was temporary increase in IOP, but we could control IOP within normal limit with transient treatment. The postoperative late complications were glaucoma, IOL decentration and cystoid macular edema, but serious postoperative complications such as bullous keratopathy and retinal detachment were not found. Conclusions: The anterior chamber IOL implantation appears to be well tolerated and represents a simple alternative to transscleral fixation of a posterior chamber IOL in completely vitrectomized aphakic eyes.
