COPENHAGEN — The Kamra inlay treats a broad spectrum of patients and is effective in both natural and post-laser vision correction presbyopes, according to Shamik Bafna, MD, who related his center’s experience with the inlay from AcuFocus.

“Every patient who walks into our office I feel can potentially become a Kamra patient,” Bafna said at the European Society of Cataract and Refractive Surgeons meeting.

Patients treated at the Clear Choice Custom LASIK Center, Ohio, with the inlay thus far have been emmetropic presbyopic patients, patients with any degree of myopia or hyperopia, post-LASIK patients who have become presbyopic and monofocal pseudophakes, Bafna said.

Since the Kamra’s FDA approval in 2015, Bafna and colleagues have implanted 127 eyes of patients whose average age was 52 years.

A bout one-fourth of the patients were typical emmetropic patients, whereas about half of patients had undergone previous laser vision correction, Bafna said. These patients underwent previous LASIK and subsequently developed presbyopia, underwent recent LASIK or underwent LASIK on the same day as Kamra implantation.

“We find that 75% of patients are not the patients who walked in your door but are patients we have to create, what I call perfect Kamra patients. ... What I mean by that is if we have a patient who comes in who is more hyperopic or more myopic, we’ll go ahead and perform laser vision correction in order to get them between –0.75 D and –1 D,” Bafna said. Afterward, the Kamra inlay would be implanted, either sequentially after refractive stability is achieved or, in their more recent experience, on the same day. – by Patricia Nale, ELS
