A 31-year-old man with myopia underwent bilateral radial keratotomy. Except for a microperforation of the cornea of the left eye, the operative procedures were uneventful. The postoperative uncorrected visual acuity was excellent in both eyes until a cataract suddenly developed in the left eye 3 1/2 months after the procedure. No preexisting ocular or systemic conditions existed to explain the sudden development of the cataract, and no evidence of iris or anterior capsular damage could be seen on examination. The sudden development of this cataract after radial keratotomy remains unexplained.

Because of their size and mass, weight is a major concern in the fitting of soft gel lenses. Lenticular design is necessary, and there are essentially two lens designs for aphakia: the spin-cast lens of Bausch & Lomb and the lathe-cut lenses of the other manufacturers. A solution to the problem of weight in a single cut soft contact lens is presented.
