Abstract:
Diurnal changes in visual acuity are often reported by patients undergoing radial keratotomy. Refraction, keratometry, and intraocular pressure were measured, 3 times a day, in 15 eyes 3-6 months after radial keratotomy, in 11 eyes one year after surgery, and in 5 controls. Higher myopia in the evening was found in 73% of the patients. All of the changes in refraction, keratometry, and tonometry were not statistically significant. No correlation was found between diurnal changes in intraocular pressure and corneal refractive power. The subjective sensation of diurnal refractive changes is usually milder one year after the operation.
