With this month’s momentous approval of the Kamra inlay for the treatment of presbyopia, refractive surgeons will now turn the page on a new era in vision correction.
The Kamra inlay (AcuFocus) represents the first major advancement in the surgical correction of presbyopia in more than a decade. Making use of small aperture optics, this 5-µ thick inlay is implanted in the line of sight into a femtosecond created pocket at a minimum depth of 200 µ. The inlays’ narrow 1.6 mm aperture blocks unfocused light from entering the nondominant eye and in so doing creates an increase in depth of focus, improving both near and intermediate vision without having a quality of vision effect on uncorrected distance acuity. FDA clinical study results of 508 patients treated worldwide indicate that greater than 95% of patients implanted enjoyed long-term improvement of near acuity across all follow-up examinations without loss of distance function or depth perception.
