[Intraocular contact lens to correct severe refractive error].
Collamer (collagen-acryl copolymer) intraocular contact lenses were implanted in the posterior chamber (sulcus) in phakic eyes to correct severe myopic patients. In addition to being myopic, they had visual problems (diminishing, contact lens coating) or direct organic eye problems (keratitis, conjunctivitis, vessel ingrowth in cornea) wearing glasses or standard contact lenses in everyday life. Seven lenses were implanted in four patients with preoperative myopia (spherical equivalents) ranging from -8.75 to -20.5 diopters (D), average myopia was -15.4, average follow up was 13.2 months. Mean postop myopia (spherical equivalent) was -1.96. Best spectacle-corrected visual acuity improved in all eyes with approximately two lines in Snellen's chart. No iritis or cataract was observed; one anterior angel closure required an additional iridotomia in one eye. The lens was well accepted, and a good functional outcome occurred within a short delay. The method holds promise as an important supplementary treatment for patients with severe refraction anomalies. It is, in fact, the only treatment for the most severe myopic and hypermetropic patients if they are to preserve their accommodative abilities.
