Long-term results with Iogel IOLs

Abstract

130 single piece hydrogel Iogel intraocular lenses (IOL) were implanted in the capsular bag after planned extracapsular cataract extraction. Anterior capsulotomy was performed by capsulorhexis in 59 patients while the envelope technique was used in 71 cases. The mean follow-up was 22 months and the average visual acuity was more than 8/10 in 78.5% of cases. In the capsulorhexis group a higher percentage of IOL was placed right into the capsular bag. No significant inflammatory and noninflammatory postoperative complications occurred. Lens decentration, observed in 5 cases, was due to asymmetric lens placement with one flange in the bag and the other in the ciliary sulcus. In both groups endothelial cell loss was about 7%. Results of the study indicate the safety and the efficacy of the Iogel lens as an intraocular implant. To prevent postoperative decentration and deformation of the IOL unnecessary intraocular manipulation and 'in-out' positioning should be avoided.
