Aberrometer
Definition
A high-precision clinical diagnostic device used in ophthalmology to automatically measure and record the total optical aberrations of the eye (both lower-order aberrations like myopia and astigmatism, and higher-order ones like coma or trefoil). The device operates based on wavefront analysis, projecting a harmless laser beam onto the retina and measuring light distortions as it exits the eye, providing an essential digital map for customized refractive surgery.
