Presbyopia remains the last frontier for refractive surgeons. With increased demand for spectacle independence at all ages, ophthalmologists are exploring different approaches for presbyopia correction. The idea of adding synthetic material to the cornea for the management of presbyopia has come a long way since its inception.
The Raindrop® (ReVision Optics®), KAMRA™ Inlays (AcuFocus™) and the Flexivue Microlens™ (Presbia™) are three very different inlays that attempt to reverse presbyopia through different mechanisms. The Raindrop changes the curvature of the anterior cornea in the plane of the pupil, the Kamra uses the principle of the pinhole to increase depth of focus, while the Flexivue is a refractive annular add lenticule that creates a paracentral zone for near vision. The decreased incidence of complications, ease of insertion, reversibility and potential applicability to patients with various refractive statuses make inlays a powerful addition to the armamentarium in the management of presbyopia.
