He noted that the refraction can change from morning until evening and there may be progressive hyperopic shift over time. Barbara Bowers, MD, in private practice, Innovative Ophthalmology, Paducah, Ky., disagrees—she'll bring these patients in at several different times throughout a day "and if the vision is fluctuating a little bit, I'll consider a multifocal. If they're fluctuating drastically between the morning and afternoon readings, I'll tell them point-blank a multifocal lens will make them miserable." Dr. Masket uses four or five devices to find the flattest Ks, and those are the readings he'll use for IOL calculation. Astigmatism is an essential component to evaluate in these eyes, said Barry Schechter, MD, in practice, Florida Eye Microsurgical Institute, Boynton Beach, Fla. "We've had some very nice results with toric IOLs in RK patients who have varying amounts of regular astigmatism," he said. "You want to look for wound gaping. If the wounds have healed nice and tight, you're more likely to get a very stable postop refraction after time, but if you see some gaping, you've got the potential for refractive surprises." If there's "very irregular astigmatism," Dr. Schechter advises against a toric—"you just have to go with a plain monofocal aspheric lens. I've been surprised with the results obtained and with the range of vision possible due to the spherical equivalent." Dr. Masket avoids toric lenses in some post-RK patients "for fear they may someday need a corneal transplant" and because it's rare to have regular astigmatism in these eyes. In general, he advises adding "about a half diopter" of measured IOL power for a patient with four incisions, between 1-1.5 D for those with eight incisions, and 2 D for those with 12 or more incisions. While intraoperative aberrometry may be very useful in eyes having prior laser vision correction, it is less accurate in the post-RK eye, as corneal curvature changes during cataract surgery in these eyes, he added. http://www.eyeworld.org/article-calcu...
