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.
