multifocal iol

A patient sees clearly both near and far after receiving a multifocal IOL.

Definition

Noun: A multifocal intraocular lens (IOL) is an artificial lens implanted in the eye, typically after cataract removal. It is designed with multiple concentric optical zones or rings, allowing it to provide clear focus for objects at multiple distances (such as near, intermediate, and far) simultaneously. This design aims to reduce dependence on glasses after surgery.

Usage

The term is used in medical and optometric contexts to describe a specific type of surgical lens implant. - The ophthalmologist recommended a multifocal IOL to correct both my distance and reading vision after cataract surgery. - Patients considering a multifocal IOL should discuss potential side effects like glare or halos with their doctor.

Advanced Usage
  • "to be implanted with a multifocal IOL": This phrase describes the surgical procedure of receiving the lens.
    • She was successfully implanted with a multifocal IOL and now enjoys good vision for driving and using her computer.
Variants and Related Words
  • Multifocal lens (n): The general optical principle; can refer to contact lenses or eyeglass lenses with multiple focal points, not just surgical implants.
  • Monofocal IOL (n): A contrasting type of intraocular lens that provides clear vision at only one fixed distance (usually far), often requiring glasses for other tasks.
  • Accommodating IOL (n): Another type of lens implant designed to shift focus by moving within the eye, rather than using multiple static rings.
  • Pseudophakic (adj): The state of having an artificial intraocular lens (IOL) implanted in the eye.
