111 EW REFRACTIVE SURGERY September 2015 the cornea and allow patients' vision to return to the preoperative state, have shown that patients did recover within one line of their best corrected vision after the inlay was removed. "I think it is a comfort level for both surgeons and patients that it is removable and the patients' corneas tolerated the surgery to put it in and the surgery to take it out. The good news is that in well-selected patients, the removal rate is running 1% or less," Dr. Durrie said. KAMRA provides a long-lasting, minimally invasive option to pres- byopes who otherwise have healthy corneas. "For this procedure, you need to have clear media," Dr. Machat said. "Any sort of scarring or problem on the cornea, even a mere dry eye, any sort of irregularity or early cataract change in the lens disqualifies a patient from getting the inlay." "[Patients] need to have a good tear film, and we need to make sure that they don't have a cataract," Dr. Durrie said. "The age group for of focus of the eye using pinhole or small aperture optics." In the clinical practice, it is more well known that changing the power of the eye means changing the shape of the cornea with lasers, like LASIK and PRK, or changing the power of the eye internally with a lens implant. Corneal inlays work with a dif- ferent mechanism. "Instead of being a lens that changes the power of the eye, this is an optical principle that increases the depth of focus," said Daniel S. Durrie, MD, founder and president, Durrie Vision, Overland Park, Kan. "You will have a large range [of vision]. That's what made this popu- lar to patients and doctors," he said. Its minimally invasive charac- teristic is another reason KAMRA is gaining popularity among pa- tients and doctors. The procedure is straightforward, easy to put in and easy to remove as well. "It takes 60 seconds or less to remove," Dr. Machat said.

The surgery is faster, easier, and less traumatic compared to previous models that needed peripheral iridectomies/iridotomies. Source: Alaa El Danasoury, MD
