EW SHOW DAILY 24 ASCRS Symposia Sunday, April 19, 2015 ophthalmologists need to pay great- er attention to this market segment. During the symposium, Karolinne M. Rocha, MD, PhD, Charleston, S.C., discussed the use of the iTrace (Tracey Technologies, Houston) to evaluate optical quality, and Robert Zaldivar, MD, Mendoza, Argentina, spoke about the HD Analyzer (Visiometrics, Terrassa, Spain). Ron Krueger, MD, Cleve- land, wrapped up the symposium by addressing adaptive optics, which are a way to measure a patient's tol- erance for negative spherical aberra- tion before surgically changing their vision. There is now a commercial adaptive optics visual simulator in- strument developed by Pablo Artal, MD, said Dr. Krueger. EW Editors' note: Dr. Hamilton has fi- nancial interests with Abbott Medical Optics, Alcon (Fort Worth, Texas), and other ophthalmic companies. Dr. Zaldivar has financial interests with STAAR Surgical. Drs. Durrie, Rocha, Stulting, and Waring have financial interests with Abbott Medical Optics, Alcon, Allergan (Irvine, Calif.), and other ophthalmic companies. Drs. Barnes and Krueger have no financial interests related to their comments. A segment of patients who may have 20/20 vision but who still have prob- lems with vision quality will be a growing target for treatment within ophthalmol- ogy, said the presenters at Saturday afternoon's symposium "Quality of Vision: Beyond 20/20." This group of patients has what Daniel S. Durrie, MD, Overland Park, Kan., described during the ses- sion as dysfunctional lens syndrome (DLS). In stage 1 of DLS, patients are in their mid 40s and early 50s. Their lenses are still clear, but they feel like their arms are too short and they've lost their ability to zoom in, he said. In stage 2, these patients are in their 50s and 60s, and their night vision is not as good, and they may feel they need more light to read. By stage 3, these patients have full- blown cataracts. "We know about stage 3. It's stages 1 and 2 that we need to ad- dress," Dr. Durrie said. Ophthalmology will have a growing focus on patients with DLS as the industry starts to develop treatments for this underserved population, said Dr. Durrie. A greater focus on presbyopic treatments like presbyopic IOLs can help improve patients' quality of vision, said D. Rex Hamilton, MD, Los Angeles, who noted that 75% of patients at his practice pay for premium IOLs and of those, 25% get presbyopic correction. However, the key is in overcoming bad first impressions of presbyopic IOLs, in- cluding the possibility of halos and unpredictable refractive endpoints. "The new IOLs are incredible, but we have to explain their limitations to avoid disappointment," Dr. Hamilton said. He has found that measuring pupil size can help reach the goal of assessing which patients are best served with multifocal IOLs. Col. Scott Barnes, MD, Ft. Bragg, N.C., addressed the ability of going beyond 20/20 vision with the use of phakic IOLs. "Twenty/twenty vision used to be perfect, but now patients want something more," he said. He spoke about the Visian ICL (STAAR Surgical, Monrovia, Calif.), which he has used in practice, and the Verisyse (Abbott Medical Optics, Abbott Park, Ill.), which he has not used. Doyle Stulting, MD, Atlanta, addressed the potential of extend- ed depth of focus IOLs, which can provide enhanced intermediate and near vision. The use of Scheimpflug densi- tometry to go beyond the measures of Snellen visual acuity as a way to assess patients' quality of vision can help analyze eyes best suited for presbyopic possibilities, said George Waring IV, MD, Charleston, S.C. Dr. Waring shared presbyopic market statistics, noting that there will be 2.1 billion presbyopes worldwide by 2020. Like the speakers before him, Dr. Waring said this is why by Vanessa Caceres EyeWorld Contributing Writer Going beyond 20/20 to meet patients' increasing demands Dr. Durrie describes dysfunctional lens syndrome to symposium attendees.
