AIMS This study aimed to evaluate stromal wound healing morphology in short term unsutured compared with sutured corneal wounds, to define regional variation in healing within radial keratotomy wounds. METHODS Stromal scar tissue orientation (fibroblast and collagen fibre orientation) was analysed in unsutured and adjacent sutured keratotomy wounds in monkeys, 2 to 9 weeks after surgery, usin...

First conceptualized by Lans, incisional keratotomy is widely used for treating astigmatism, although it is now only infrequently used for treating myopia. The current methods of refractive keratotomy derive from the work of Fyodorov in Russia in the mid-twentieth century. Radial incisions cause the peripheral cornea to bulge outward, producing central flattening. Astigmatic keratotomy (AK) and...

PURPOSE To evaluate laser in situ keratomileusis (LASIK) for induced hyperopia after radial keratotomy. METHODS Twenty eyes had LASEK for induced hyperopia after radial keratotomy. All eyes were treated using the Nidek excimer laser (EC-5000) and the Hansatome microkeratome with a 905-mm ring and 180-mm plate. Hyperopic correction was done using a 5.5 to 7.5-mm ablation zone. RESULTS Mean p...

The authors analyzed refractive results of patients who underwent radial keratotomy (RK) at sea level and high altitude and evaluated the effects of the altitude. A total of 102 eyes undergoing RK procedures performed in two clinical centers having different altitude were analyzed. The results compared between subjects who had undergone RK at sea level (Istanbul/Turkey) and at an altitude of 57...

purpose : to compare results of different methods for true corneal power determination and intraocular lens (iol) power calculation formulas in 10 eyes of 7 patients with previous radial keratotomy (rk) with or without astigmatic keratotomy methods : in this case series study, we determined the corneal power of 10 eyes of 7 patients who had undergone rk with or without astigmatic keratotomy wit...

BACKGROUND Five years ago, we presented 19 procedures employing two intrastromal purse-string sutures to treat hyperopic shift following radial keratotomy. Thirty-four additional procedures and longer follow-up are now presented detailing the task of rehabilitating these eyes. METHODS Fifty-three eyes of 53 radial keratotomy patients who were unhappy with their uncorrected vision and who were...
