Refractive outcome of silicone oil removal and intraocular lens implantation using laser interferometry.

Abstract

To evaluate the refractive outcome of silicone oil removal and intraocular lens (IOL) implantation using laser interferometry. Thirteen silicone oil-filled eyes of 12 patients were included in the study. IOL power calculation was performed using laser interferometry (IOLMaster V1.1; Carl Zeiss, Jena, Germany). All of these eyes underwent silicone oil removal and cataract extraction with IOL implantation. Post-operative refraction was evaluated. The mean deviation of the final post-operative refraction (spherical equivalent) was -0.30+/-0.91 D (range, -1.87 to +1.3) at 12 weeks. The mean axial length of the eyes was 22.99+/-0.84 mm (range, 22.07-25.24 mm). No major complications occurred intra- or post-operatively. Laser interferometry appears to be a feasible and satisfactorily accurate method to calculate IOL power in some silicone oil-filled eyes. Further studies comparing this technique to others are warranted.
