What's mean of Spheric Intraocular lenses?

Answer 1

Spheric intraocular lenses (IOLs) are artificial lenses implanted in the eye, typically after cataract surgery, to replace the eye's natural lens. These lenses have a uniform curvature, which helps to focus light onto the retina, providing clear vision. Unlike aspheric lenses, which are designed to reduce spherical aberration and improve contrast sensitivity, spheric IOLs offer a simpler design and are often used for patients with standard vision correction needs. They can be monofocal or multifocal, depending on the patient's visual requirements.
