Aberrometry | Measurement and correction of optical irregularities of the eye

Aberrometry is a technique that measures the way the "wavefront" of light passes through the dioptric apparatus of the eye (cornea and lens). Distortion that occurs during the passage of light is called aberration and represents specific visual errors.

Determining aberrations is an important part of the examination, and with waferfront technology they can be precisely defined. The recording takes a few seconds and when it is done, a wavefront map is obtained, on the basis of which the method of aberration correction is planned. Many aberrations can be corrected with certain glasses, contact lenses and refractive surgery.

Dry eye, keratoconus, corneal scarring, and cataracts are examples of eye conditions in which higher-order aberrations occur. Huvic's autokeratore refractometer (which is part of the equipment available in the clinics of the Dr. Raonic Ophthalmological Center) has an algorithm for wavefront analysis and goes beyond general refraction to infer very precise and reliable refractive power and corneal index.
