Scleral Fixated Intraocular Lens Implantation in Patients with Luxated Lenses

Purpose: To investigate the efficacy and safety of scleral fixated intraocular lens (SFIOL) implantation in patients with luxated lenses (traumatic or developmental). Methods: We retrospectively evaluated the results of 20 eyes operated because of lens luxation and implanted with a scleral fixated intraocular lens. Eight of the cases were traumatic and unilateral; 6 of them were developmental and bilateral. Nine of the cases were male and 5 were female. The mean age was 33.9 +/- 26.4 years. We preferred intracapsular lens extraction+anterior vitrectomy+SFIOL in 4 eyes and limbal or pars plana lensectomy+anterior vitrectomy+SFIOL in 16 eyes. Results: The postoperative follow-up time was 14 +/- 9.1 months. We recorded visual increase in varying degrees in all cases except the one with traumatic lens luxation because of degenerative myopia. We experienced hyphema in 2 eyes and mild vitreal hemorrhage in 2 eyes intraoperatively. The hemorrhages in these eyes resorbed without any intervention. We saw glaucoma in 4 cases during the follow-up time and controlled with antiglaucomatous medications. The glaucoma preoperatively seen in 4 eyes with developmental glaucoma and thought to be a result of lens luxation resolved after the operation. Intraocular lens reposition was needed in one traumatic case. Suture erosion was noted in one case and we repaired with a conjunctival flap. We did not record retinal detachment or endophthalmitis in any case. Conclusion: SFIOL is an effective and safe surgical technique in the visual rehabilitation of patients with lens luxation. The timing of the lens extraction is very important to prevent the complications related to lens dislocations. The cases should be regularly followed to detect and treat the probable complications.
