162 EW MEETING REPORTER March 2013 Reporting live from Hawaiian Eye 2013, Big Island, Hawaii She also suggested using a femtosecond laser to create a new side cut at the edge of an old LASIK flap to lift the flap. Editors' note: Dr. Wu has no financial interests related to her talk. Imaging the cornea Editors' note: This Meeting Reporter contains original reporting by the EyeWorld news team from Hawaiian Eye 2013. When screening candidates for corneal refractive surgery, Placido topography remains the best way to detect keratoconus, a speaker said at Hawaiian Eye 2013. "Accurate topography is essential for keratorefractive surgery," said Stephen Klyce, Ph.D., New York. "Look for tomography to help in this aspect, and possibly very high frequency ultrasound may help in the future." He also said Placido topography for Ks and aberrations, tomography for internal cylinder and optical coherence tomography (OCT) or 3D-CSI for femtosecond cataract surgeries are helpful tools in cataract refractive procedures. Dr. Klyce said he is particularly excited about the applica- tion of high-speed swept source OCT for corneal imaging. "We get not only axial power of the front surface of the cornea, we also get the back surface of the cornea and pachymetry," he said. "This is technology you should be looking forward to in the future." For its part, very high frequency ultrasound is the only technology that gives surgeons a sulcus-to-sulcus measurement, he added.

Comparing IOLs A prospective, randomized, partially masked post-market FDA study of three presbyopia-correcting IOLs showed that the ReSTOR 3 (Alcon, Fort Worth, Texas) had the most favorable subjective response in subscales for distance, according to a study presented at Hawaiian Eye 2013. The Tecnis Multifocal (Abbott Medical Optics, AMO, Santa Ana, Calif.) and ReSTOR 3 showed the most consistent favorable responses for near vision performance, which was consistent with their acuity results, reported Jay S. Pepose, M.D., St. Louis. The Crystalens AO (Bausch + Lomb, Rochester, N.Y.) had the lowest glare, halo and scatter scores, as well as the best uncorrected and best corrected intermediate vision. "Each IOL has inherent strengths and weaknesses and has made iterative improvements in comparison to its predecessors," Dr. Pepose said. "Careful attention to patients' lifestyle and visual priorities, along with their pupil size and dynamics, angle kappa, corneal higher-order aberrations and macular status can play an important role in allowing the surgeon to select a specific lifestyle IOL for each patient and to help shape realistic expectations."
