Gazi Üniversitesi Göz Hastalıkları ABD Purpose: To evaluate various surgical techniques and outcomes in eyes with lens dislocation into the vitreous.
Materials and Methods: Seventeen eyes of 17 patients with a mean age of 49.6 years(range 11-77 years) were evaluated. Lens dislocation was due to ocular trauma in 14 eyes and due to insufficient, weak zonules in 3 eyes. Retinal detachment in 5 eyes, vitreous hemorrhage in 2 eyes and choroidal neovascular membrane(CNV) in 1 eye was accompanying to lens dislocation. In all eyes, liquid perfluorocarbons were used for floating the dislocated lens. In 3 eyes, lenses were extracted through cornea scleral incision, in 5 eyes pars plana phacoemulsification and in 9 eyes pars plana lensectomy was performed. Retinal attachment was provided in 5 eyes and macular translocation via scleral imbrication was applied to the eye with CNV. Intraocular lens implantation with scleral fixation was done in 4 eyes. Mean follow-up period was 5.5 months (range 4-13 months).
Results: Retinal detachment was seen in 2 eyes within the first two weeks postoperatively and retinal attachment was provided via fluid-air,air-gas (C3F8) / silicone oil exchange and laser endophotocoagulation. Hyphema was seen in 1 eye and mild submacular hemorrhage in the macular translocation which resolved spontaneously in both eyes. Best corrected final visual acuity remained same in 1 eye(6 %), decreased in 1 eye(6 %), and increased in 15(88 %) eyes.
Conclusion: In the treatment of lens dislocation into the vitreous, accompanying posterior segment complications and the age of the patient should be considered for the appropiate surgical procedure to get successful results.
