WebMar 15, 2003 · Dr. Arbisser also thinks it's appropriate to start at "near clear" cornea rather than actual clear cornea with the cataract wounds, "in order to leave a little limbus or sclera available to make sure you don't break through the RK incisions or allow them to dehisce." She says this is particularly useful when placing the IOL inserter. When performing RK, incisions are made with a diamond knife. The incisions relax the steep central cornea in patients with myopia in order to achieve a decreased need for correction. The original technique – consisting of incisions from periphery to center – was called the "Russian technique", while the later advances of performing controlled incision from center to periphery was called the "American technique".

WebApr 12, 2011 · However, the complications associated with RK, such as glare, halos and unstable corneas, resulted from too much RK being done and cutting with small optical zones. My approach only uses two incisions and doesn’t go smaller than a 4-mm optical zone, which I feel promotes a stable result. WebFeb 11, 2013 · Radial keratotomy (RK) is a procedure in which multiple radial incisions are made in the corneal epithelium and stroma, ideally reaching a depth of 85% to 95% of the total cornea thickness for the purposes of reducing or eliminating refractive error.
