Precision standardization of radial keratotomy

Radial keratotomy is an experimental surgical procedure being performed in increasingly large numbers, often without carefully designed protocols which meet accepted methodology for clinical research. This paper presents an instrumentation system which makes it possible to have precise control of the length, depth, and spacing of radial keratotomy incisions. This is not a paper in favor of radial keratotomy. It raises the need for rigid standardization of the technique with evaluation of the results according to carefully controlled and accepted clinical trial methodology.
