RADIAL KERATOTOMY: RATE OF SUCCESS, SIDE EFFECTS
The rate of success averages 85 percent among all of the eye surgeons performing radial keratotomy. Some are getting as high as 92 percent successes with their formerly myopic patients, but others report a 55 percent success ratio. As with other medical procedures, the result of the operation depends on the skill of the surgeon, his technique, and the severity of the patient's nearsightedness. Some doctors are taking only more difficult cases so that their success rates are lower. Others accept just the easier myopics so as to have better success rates.
In the postoperative management period, a slit lamp follow-up examination is essential. Corneal curvatures must be measured periodically, and temporary glasses are sometimes used during the recovery period. Additionally, for those patients who don't get a full correction of their myopia (for example a minus six diopter reduced to a minus two diopter), corrective lenses either as spectacles or contacts may still be required.
Some patients complain of the side effect of glare while driving at night, but this generally resolves by the end of two or three months. If a mild infection occurs, it is readily managed with medicated eye drops. Complete healing may take up to two months, during which the surgeon follows the patient's progress closely to assure the proper amount of corneal flattening. Sometimes the operation, which remains classified by ophthalmologists as investigational, having been removed from the "experimental" category several years ago, is repeated to insure a perfect result. Other brief complications are redness and temporary sensitivity to light.
