Spherical aberration is a term often used in ophthalmology and optometry, especially in relation to lens surgeries and intraocular lens design. Recently, IOL manufacturers have been manipulating spherical aberration as a tool to provide a greater range of vision, but rarely explaining the mechanism. Your OATR hosts, Dr Nick Andrew and Dr Ben LaHood, as always, discuss the simple things often overlooked and the complex things often ignored in the eye world. They take a deep dive into spherical aberration of the eye to provide you with a better understanding of an increasingly important topic for ophthalmologists and optometrists.
