[Myopic anterior chamber intraocular lens implantation: evaluation at 8 years].

PURPOSE
The aim of this study was to analyse the tolerance of Myopic Anterior Chamber IOL's 8 years after surgery.


MATERIAL AND METHODS
We have studied 21 eyes implanted with an anterior chamber phakic IOL between May 1989 and June 1990. The 21 eyes had a very high 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 refraction of -0.25 D. Post-operative complications were a pupillary ovalisation in 42% of the eyes and glare in 50% of the eyes. Specular microscopy was normal pre-operatively for all the eyes but at 8 years, 4 (19%) of the eyes have had a strong loss of their endothelial cells and have to be explanted. Decreasing of endothelial cells is the most severe complication occurring after Phakic anterior chamber myopic IOL implantation.


CONCLUSION
These 21 Myopic Anterior chamber IOL's have given a very good refractive result for all the eyes. 4 (19%) of the eyes operated on with these 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.
