بررسی تأثیر اعمال جراحی پیوند ثانویه عدسی داخل چشمی

Background and purpose : Many aphahic patients have unfavorable vision either with glasses or contact lens. In this study Visual outcome of Seconary (I.O.L) was implantation in aphakic patients referred to Imam Hossein Haspital 1994 evaluated. Materials and Methods : In a clinical trial with sequential sampling , 30 aphakic patients (26 males , 4 females mean of age 24.4 ± 10.8 years) who had previous cataract surgery , were selected. The exclusion criteria were : previous lens implant visual acuity less than corneal edama intraocular inflammation or increased pressure vitreous loss or significant iridectomy during cararact surgery macular edema and vitreous opacity. Further evaluations and follow-ups were done blindly by ophthalmology residents from 24 hours after implantation upto 2 months after removal of sutures. The statistical assessment of the results was done by using Mc Memar tesr. Results : Secondary inmplantation of intraocular lens increased the number of patients with visual acuity of from 6.7% to 30% , which was statistically significant(p<0.02). Conclusion : By appropriate patient selection , secondary I.O.L. implantation is a good surgical approach in aphakic patients , to give them better binocular vision and to avoid the side effects of glasses and contact lens
