see url Patient to view a visual acuity chart through adaptive optics. The AO system automatically measures and corrects the aberrations of the patient’s eye and provides a prescription for glasses, contact lenses, or refractive surgery. The phoropter measures the eye’s wave aberration with a Shack–Hartmann wavefront sensor. Wavefront correction in the phoropter is achieved with a microelectromechanical systems (MEMS) deformable mirror. 2 Image Quality Metrics Assessed with Adaptive Optics The effective use of wavefront sensing to refract the eye depends on the ability to transform the wave aberration, which is usually defi ned by several dozen Zernike coefficients, into the values of sphere, cylinder, and axis that generate the best subjective image quality.

The best ophthalmic adaptive optics systems today already approach diffraction-limited imaging using the fully dilated pupil. Modest improvements will no doubt accrue through improved wavefront sensing, better deformable mirror technology, more careful calibration, and optimized control algorithms. Small resolution gains could be achieved by decreasing wavelength, but this approach is problematic because of the eye’s susceptibility to damage at short wavelengths [75]. The most significant gains are likely to arise by combining adaptive optics with new imaging technologies.
