3Şişli Etfal Eğitim ve Araştırma Hastanesi, 1.Göz Kliniği, İstanbul, Uz. Dr. Purpose: To evaluate the patients who underwent scleral fixated intraocular lens (SF-IOL) implantation in terms of etiology, surgical method and outcome.
Materials and Methods: Nine patients who underwent SF-IOL implantation between November 2008 to November 2010 were evaluated regarding patients' ophthalmologic backgrounds, preoperative indications, postoperative findings and prognosis.
Results: Two of the patients were female and seven were male. The mean age of the patients was 52. The mean follow up time was 5.7 months. The indications were; aphakia related with primary surgery (5 cases), posttraumatic spontaneous lens resorption (1 case), IOL dislocation after primary cataract surgery (2 cases) and subluxation of crystalline lens spontaneously (1 case). Four of the patients had a history of blunt orbital trauma, and one of them had been repaired for corneoscleral rupture due to blunt trauma following pterygium excision with mitomycine. We performed pars plana vitrectomy (PPV) and intravitreal silicone oil injection to 3 of these cases. Indications for the surgery were retinal detachment (2 cases), intravitreal hemorrhage and luxation of the crystalline lens into the vitreous (1 case). At the time of silicone oil removal, SF-IOL was implanted to two of these. The preoperative best corrected visual acuities (BCVA) ranged between finger counting at 1 meter distance and 1.0. The postoperative BCVA varied between 0.05 and 1.0.
Conclusion: Implantation of SF-IOL may be a useful method for rehabilitation of aphakia in eyes with absent zonular or capsular support. Visual outcomes depend on the etiology. Achieving an increased visual outcome or preserving preoperative BCVA could be succeeded, if SF-İOL implantation is performed as primaryly or secondaryly.
