[Implantation in severe myopia cataract].
Based upon biometric and statistical analysis of 163 eyes (26 mm or longer), it appears that high myopia cataract occur all the earlier as the eye is long; on average, these were operated on ten years earlier than cataracts in the general population. Extra-capsular extraction and intercapsular implantation were generally used. Pre and post-operative complications are remarkably rare for such abnormal eyes. After a mean period of 22 months, detachment of the retina was observed in 1.84% of patients and secondary capsulotomy performed in 8%. Because they prevent secondary capsular opacification and anterior vitreous propagation, it appears that such barrier-type implants should be systematically placed. Current large-diameter implants allow for vitreoretinal observation. Based upon this patient population, a formula for implant power calculation specific to high myopia has been elaborated. The desired degree of refraction varies with age and patient activity.
