multifocal IOL
Also written as: IOL — intraocular lens
An intraocular lens designed with multiple focal points to provide vision at various distances without glasses.
Full Definition
A multifocal intraocular lens is an advanced lens implant that incorporates multiple optical zones or diffractive patterns to create several focal points, allowing patients to see clearly at distance, intermediate, and near ranges. These lenses are designed to reduce dependence on corrective eyewear following cataract surgery. Editorial considerations include proper hyphenation of the compound modifier, consistent abbreviation usage, and accurate representation of the technology's benefits and limitations. The term encompasses various designs including refractive multifocal, diffractive multifocal, and hybrid designs, each with specific optical properties that may require precise terminology in clinical documentation.
Usage
Usage note: Hyphenate when used as a compound modifier before a noun. Consider context when abbreviating intraocular lens.
