Spoke keratotomy was performed on human cadaver eyes in hopes of developing an incisional refractive surgical technique to correct higher degrees of myopia compared with radial keratotomy. This new incisional refractive technique produced less than half of the total corneal flattening produced by standard four- and eight-incision radial keratotomy and was technically more difficult to perform.
