accommodative IOL
Intraocular lens designed to provide focusing ability across multiple distances.
Full Definition
An accommodative IOL is a type of intraocular lens designed to provide some degree of focusing ability or accommodation after cataract surgery, potentially reducing dependence on reading glasses. These lenses utilize various mechanisms including forward movement, shape change, or dual-optic systems to alter effective power for near vision. While accommodative IOLs can provide improved intermediate and near vision compared to monofocal lenses, they typically provide less accommodation than the natural crystalline lens in young patients. Patient selection and realistic expectation setting are crucial for successful outcomes with accommodative IOL technology.
Usage
Usage note: Distinguish from multifocal IOLs which use different optical principles.
