Correcting Presbyopia with Intracorneal Inlays

By using a pinhole effect to enhance patients' depth of focus, the AcuFocusTM corneal inlay offers a new approach to correcting presbyopia.

Although many different types of presbyopia correction are currently available, none can give patients a full range of vision without compromise. With progressive lenses, for example, patients gain good vision at a range of distances, but they must also tolerate some degree of marginal astigmatism and deal with the hassle of glasses. Among surgical options for presbyopia, multifocal intraocular lenses (IOLs) impair contrast sensitivity and may cause glare and halos at night, while monovision treatments compromise stereopsis and depth perception.

To minimize such trade-offs, an intracorneal inlay has been developed that improves patients' near vision by enhancing depth of field. While this approach still has some drawbacks, it gives patients good vision at all distances in most lighting conditions without compromise. The AcuFocusTM inlay, currently in clinical trials with the FDA, could provide an excellent option for treating presbyopia.
