- Abbe surgical technique / Abbe device — The term refers to medical eponyms derived from scientific figures: in plastic surgery, the 'Abbe flap' (pioneered by Robert Abbe) is a lip reconstruction technique; in medical optics and ophthalmology, the 'Abbe number' or 'Abbe condenser' (Ernst Abbe) defines light dispersion in lenses and the illumination system of clinical microscopes.
- Abero- (combining form) — A learned combining form used as a prefixoid in modern medical and technical terminology to construct terms related to aberrations, optical deviations, or refractive measurements of the human eye. It serves as a fixed structural root for developing advanced diagnostic instrumentation in refractive laser surgery, conceptually linking physical aberration to the direct geometric analysis of the transparent media of the eyeball.
- Aerocystoscope — An endoscopic medical instrument specially designed for the direct visual examination of the inside of the urinary bladder after it has been mechanically distended by insufflating sterile air or another gas, instead of liquid. This device allows the urologist to inspect the bladder mucosa without the optical distortions sometimes caused by fluids.
- Axometer — An apparatus, measuring instrument, or precision optical device utilized to determine the exact localization, geometric orientation, and alignment of the optical or geometric axes of lenses (especially cylindrical or toric lenses designed for astigmatism correction). This structural calibration apparatus is widely used in medical optics workshops and engineering laboratories to guarantee a delicate mounting and perfect centering of transparent components.
