Since the introduction of radial keratotomy, accurate incision depth has been difficult to achieve with any corneal knife. To assure repeatable depth of incisions and to adjust the refractive effect of these incisions after the surgery, I have developed a series of techniques that are described in this article and that I refer to as "tickles" in discussion with the patients. Seventeen eyes, fro...

BACKGROUND An understanding of physiologic age-related shifts in myopic refractive errors is important to the refractive surgeon for the interpretation of long-term results, surgical planning, and patient counseling. This study characterizes the refractive stability of adult simple myopia with a retrospective study of 413 eyes. METHODS Approximately 74,000 patient records were analyzed to ide...

IOL power calculation after keratorefractive surgery is an important applied aspect of cataract surgery. The probability refractive error especially high when calculating in patients with a history radial keratotomy. There no unified approach to the tactics and methodology for this category at moment. studies were conducted group 17 (26 eyes) RK. Haigis formula, which does not use keratometry p...
