Secondary intraocular lens implantation in aphakic eyes following vitrectomy / 中华眼底病杂志

ABSTRACT

Objective To evaluate the visual results,surgical technique and safety of secondary intraocular lens (IOL) implantation in aphakic eyes following vitrectomy and lensectomy for complicated ocular trauma or retinal detachment. [WT5”HZ]Methods The clinical records of 32 cases (32 eyes),received these surgeries during November 1996 and December 1999,were reviewed retrospectively.During the secondary operation,intraocular infusion through the pars plana was performend and the type of IOL was chosen based on the integrity of lens capsule. [WT5”HZ]Results The study included 30 eyes suffering from trauma (foreign bodies in 15 eyes,penetrating injury with traumatic endophthalmitis and with vitreous hemorrhage in 6 eyes respectively,blunt trauma with lens dislocation in 3 eyes),and 2 eyes with primary retinal detachment.Those eyes all received vitrectomy,lensectomy,and/or removal of foreign bodies and corneal suture.The interval of two operations ranged from 1 to 16 months with an average of 6.8?3.7 months.Posterior chamber IOL was implanted in the ciliary sulcus in 25 eyes with a whole or 2/3 of lens capsule,trans scleral suture fixation of IOL in 5 eyes,anterior chamber IOL and IOL with artificial iris in one eye respectively.Silicone oil was removed in 5 eyes during the secondary operation.Post operative visual improvement was achieved in 29 eyes.Main complications were corneal edema and low intraocular pressure after operation. [WT5”HZ]Conclusion Intraocular infusion and proper IOL implantation during the secondary operation following vitrectomy can provide selected aphakic eyes with better visual recovery.
