[Surgery for severe myopia].
High myopia is such a major visual handicap that it justifies a search for surgical corrective methods to replace contact lenses when these can no longer be worn. However, the existing techniques meet, in their principle, with physiological and anatomical constraints which explains why none of these procedures can ensure predictable and stable results without significant risk of long-term complications. The methods used to modify the surface of the cornea and its power of refraction (corneal diopter) are keratomileusis and epikeratoplasty. The methods that act on the anterior segment and modify the overall dioptric power of the eye are myopic implants and clear lens surgery. All these procedures do is modify the refraction power of the myotic eye and suppress, or alleviate, the need for glasses or contact lenses. However, surgery does not protect against the mainly retinal complications of high myopia.
