Centration, Endothelial Cell Count and Functional Results after Implantation of Foldable Silicone Lenses

Abstract

Objective: Long-term evaluation of astigmatism, visual acuity, endothelial cell count and intraocular lens decentration after implantation of a 6.0 mm flexible silicon lens. Study Design: A prospective study with examination of the patients one day, one week, 3, 6,12,18 and 24 months post-operatively with comparison of the pre-operative status. Patients: 30 patients (aged 59 ± 12 years) were followed for 24 months. Main Outcome Measures: Visual acuity, astigmatism, endothelial cell count, decentration of the intraocular lens. Results: After 24 months visual acuity reached 1.05 (±0.24), the astigmatism was −0.35 ± 0.5), and the total endothelial cell loss was below 20%. All lenses remained centred in the capsular bag with a mean deviation from the optical axes of only 64μ ± 39μ. Conclusions: We conclude that these small scleral incisions required for flexible silicon IOL shortens the time for rehabilitation and revealed no severe dislocation of the implant after 24 months.
