![]() ![]() The inlay was initially placed under a standard LASIK flap, but the shallow implantation tended to produce dryness and other problems. “The take-home message for us was that we began implanting the inlays at 250 μm or deeper.”ĭeeper implantation was not a complete surprise, he continued. “During the first Kamra inlay user group meeting in 2015, surgeons began sharing their experience with implanting the inlay deeper,” he added. “Some patients were having a hyperopic shift in their prescriptions, usually 3 to 6 months after surgery. “We began by seeing clinical results that were similar to the FDA study,” Dr. The average preoperative spherical equivalent for the shallow-implantation group was -0.45 D compared with -0.49 D for the deep-implantation group. The retrospective case analysis study compared visual results for 75 inlays implanted less than 250 μm deep and 58 inlays implanted between 250 and 300 μm. Hoopes highlighted 12-month outcomes for the first 2 years of corneal inlay implantations performed at the Hoopes Vision Center. “Our experience shows that your patients will reap a very clear clinical reward.”ĭr. Hoopes Jr., MD, Hoopes Vision Center, Salt Lake City. “Don’t be afraid to place deeper than the labeling,” said Phillip C. (The target-depth for the intrastromal pocket should be between 200 and 250 μm.) While the inlay’s instructions for use indicate the creation of a stromal pocket with a minimum depth of 200 μm for placement, implanting the device at 250 μm or deeper produces more stable refraction and improved visual acuity. Clinical experience suggests that a corneal inlay (Kamra, AcuFocus) produces better visual and clinical results when implanted deeper than recommended by the product labeling.
