The inlays are "extremely safe when placed properly," Dr. Maloney said, acknowledging there will be a small learning curve as surgeons adopt the technology. "The most difficult thing they'll face is inserting the inlay, releasing it, and centering it," he said. While h e predicts the inlays will command a large portion of the refractive mar- ket, he doubts they will become a strong add-on in cataract surgery. "Most surgeons will choose to use multifocal IOLs rather than implant- ing a monofocal lens and inlay into one eye," he said. People who are tolerant of monovision "are likely going to succeed with this technology," Dr. Slade said. "Over time as these be- come adopted into practices, I think we'll find the sweet spots in terms of t he perfect candidate." Dr. Waring concurred, noting treatments will be tailored "to the needs of the patient in terms of safety, optics, and lifestyle, in that order." Someone with a clear crys- talline lens who is not hyperopic is best served with a corneal-based solution, he said. Blended vision " works, and has worked for a long time. I envision that once available, inlays will be used much more often in the appropriate cases" as the inlays preserve distance vision in the non-dominant eye, provide full depth of focus relative to a fixed near point in blended vision, and stereovision is preserved relative to blended vision. "That's why these are so popular where they're approved outside the U.S.," Dr. Waring said. Outside the U.S. Surgeons in Asia and Europe are evaluating the inlays in combina- tion with laser vision correction, Dr. Maloney said, to simultaneously make patients emmetropic and treat presbyopia. Dr. Slade said "a few" physicians overseas are using multiple inlays, b ut that no U.S. investigator has real-world experience to be able to definitively predict which device will dominate market share (if any). "Some products we use the brand does not matter; I'm not sure if the inlays will fall into that cate- gory," he said. "I think some may do better than others, but we hope all the technologies succeed." Dr. Maloney said he's "excited about having one more tool to ad- dress refractive errors. When all you have is a hammer, everything starts t o look like a nail." E W Editors' note: Dr. Maloney is an investigator for AcuFocus and Presbia.
