CEDARS Debates is a monthly feature in Ocular Surgery News. CEDARS — Cornea, External Disease, and Refractive Surgery Society — is a group of cornea, cataract and refractive surgery specialists, here to discuss some of the latest hot topics in ophthalmology.

With laser refractive surgery becoming so widespread over the past 20 years, there is now an ever-increasing number of post-refractive patients who require cataract surgery. IOL calculations are much less accurate with traditional methods after refractive surgery, yet post-refractive patients seem to have a particularly high demand for the best refractive result possible. How to calculate IOL power for these patients has become a major problem for cataract surgeons. This month, David Goldman, Parag Majmudar and Tal Raviv discuss various options for IOL calculations, including the ASCRS online calculator, OCT-based corneal measurements and intraoperative aberrometry.
