Aberrations and accommodation [PDF]
Clinical and Experimental Optometry, 2020 Modern methods of measuring the refractive state of the eye include wavefront sensors which make it possible to monitor both static and dynamic changes of the ocular wavefront while the eye observes a target positioned at different distances away from the eye.

Optical Correction of Keratoconus with a Scleral Gas-Permeable Lenses
Oftalʹmologiâ, 2019 The optical properties of the cornea are determined by its ability to refract and transmit light. Keratoconus changes cornea’s shape, the surface of the cornea becomes irregular, which leads to a violation of light refraction and the occurrence of ...
