An improved method of silicone oil removal combined with intraocular lens implantation in aphakic eye

Abstract

Objective To observe the clinical effect of improved method of silicone oil removal combined with intraocular lens implantation in aphakic eyes. Methods A total of 89 aphakic eyes of 89 cases with silicone oil filling were enrolled. All cases had accepted lensectomy combined with vitrectomy and silicon oil tamponade for complicated retinal detachment and lens opacity, before surgery the corrected visual acuity were≥0.02. The laser photocoagulation on peripheral retina was done before operation. During operation, intraocular lens was implanted after silicone oil removal through a corneal limbus tunnel incision, and fixed in the ciliary sulcus by the suture was guided to the fornix with a circuitous way in the scleral layer. The patients were followed up for 3-6 months. The visual acuity, intraocular pressure, intraocular lens position and the condition of retinal redetachment were observed. Results In all 89 eyes, silicone oil removing and intraocular lens implantation were operated successfully. During operation, a small amount bleeding at the puncture site occurred in 2 eyes. Slight deviation of intraocular lens after operation occurred in 1 eyes and no diplopia, glare or other clinical symptoms.The postoperative uncorrected visual acuity was significantly improved (P<0.05). Conclusion Silicone oil removal through the corneal limbus tunnel incision combined with the lamellar scleral suture to fix intraocular lens is a safe, effective and easy surgical method for aphakic eye with silicone oil filling. The preoperative laser photocoagulation on peripheral retina may reduce the rate of recurrent retinal detachment. Key words: Aphakic eye; Silicone oil removal; Lens, intraocular; Retinal detachment
