Myopic anterior chamber IOL's 8 years after surgery

Purpose : The aim of this study was to analyse the tolerance of Myopic Ante rior Chamber IOL's 8 years after surgery. Material and methods : We have studied 21 eyes implanted with an anterior c hamber phakic IOL between May 1989 and lune 1990. The 21 eyes had a very hi gh myopia (mean pre-operative myopia -13,5 Dipters). Surgical technique was easy, without peroperative complications. Results: Post-operative refractive results were excellent with a mean refra ction of - 0.25 D. Post-operative complications were a pupillary ovalisatio n in 42 % of the eyes and glare in 50 % of the eyes. Specular microscopy wa s normal pre-operativly for all the eyes but at 8 years, 4 (19 %) of the ey es have had a strong loss of their endothelial cells and have to be explant ed. Decreasing of endothelial cells is the most severe complication occurin g after Phakic anterior chamber myopic IOL implantation. Conclusion: These 21 Myopic Anterior chamber IOL's have given a very good r efractive result for all the eyes. 4 (19 %) of the eyes operated on with th ese IOL's had a decreasing of their endothelial cells and the IOL had to be removed. Rigourous follow-up of the implanted eyes is required.
