Anterior Corneal, Posterior Corneal, and Lenticular Contributions to Ocular Aberrations [PDF]

Investigative Opthalmology & Visual Science, 2016
To determine the corneal surfaces and lens contributions to ocular aberrations.There were 61 healthy participants with ages ranging from 20 to 55 years and refractions -8.25 diopters (D) to +3.25 D. Anterior and posterior corneal topographies were obtained with an Oculus Pentacam, and ocular aberrations were obtained with an iTrace aberrometer ...

Optical Aberrations and Wavefront

Türk Oftalmoloji Dergisi, 2014
The deviation of light to create normal retinal image in the optical system is called aberration. Aberrations are divided two subgroup: low-order aberrations (defocus: spherical and cylindrical refractive errors) and high-order aberrations (coma ...
