Abstract
As refractive surgery gets simpler, safer, more predictable and more effective, it becomes more popular. While cases of simple myopia are usually easy to handle and get satisfactory results when corrected with excimer laser, those with high myopia still represent some challenges.
To get the best possible outcome, the surgical plan should be tailored individually to suit each particular case with its peculiar characteristics regarding patients age, activities, visual needs, expectations and of course not the least his own eye parameters.
In an attempt to better understand this issue, this study was conducted including ninety eyes of 48 patients, 22 males (45.8 %) and 26 (54.2%) females with a mean age of 40.66±12.03 (range 20 to 63) years and mean spherical equivalent of -12.67±4.64 (range -24 to -7.5) diopters. They were divided into three equal groups.
The first group (A) underwent phakic intraocular lens implantation namely Kelman duet lens which is an angle supported anterior chamber phakic lens with rigid tripod haptic and foldable optic that can be injected through a self sealed clear corneal incision of as small size as two mm to be assembled to the previously implanted haptic.
The second group (B) under went LASIK after doing the necessary investigations to exclude keratoconus suspects and to make sure that the cornea has enough thickness to allow complete correction of the refractive error in an ablation diameter that matches the scotopic pupil size.
The third group (C) underwent clear lens extraction using micro-incision cataract surgery followed by implantation of acrylic foldable posterior chamber IOLs.
