IOL Power Calculations After Keratorefractive Surgery
IOL Power Calculations After Keratorefractive Surgery How the Pentacam simplifies an increasingly important task. BY WARREN E. HILL, MD Performing IOL power calculations for eyes with prior RK and LASIK is becoming more and more of a problem for ophthalmologists; in fact, it is something of a tsunami that will wash over many practices. In the US alone, millions of patients have undergone RK and LASIK since these procedures were first introduced, and a significant portion of these individuals are nearing the age at which cataract surgery is becoming commonplace. More than ever, ophthalmologists now need a workable strategy for easily and successfully handling IOL power calculations following all forms of keratorefractive surgery. A TWO-PART PROCESS Calculating the IOL power for the postkeratorefractive surgery patient is a two-part process. First, we must estimate the central corneal power as best as we can. The problem with using standard equipment is that keratometer...
