High Precision Piezomechanic Scanners Improve Laser Control In Ophthalmology

Vision defects have been successfully corrected with optical glass dating as far back as medieval times, and the first clinical studies investigating surgical methods to “shape” the cornea started in the last century. Now, a number of different laser methods are used to influence the curvature of the cornea and correct visual acuity. These systems with high laser beam control and focusing require high-precision positioning systems. This article discusses the benefits of piezo-based mechanisms that are precise, fast, reliable, and can be integrated into today’s laser systems due to different and compact designs.
