multifocal lens implant
A patient sees clearly both a distant clock and a book in their hands after receiving a multifocal lens implant.
Noun: A multifocal lens implant is an artificial intraocular lens (IOL) surgically placed in the eye to replace the natural lens. Its defining feature is a design containing several concentric optical rings. This design allows the lens to provide focusing power for multiple distances (typically both near and far) at the same time, reducing or eliminating the need for glasses after cataract surgery or refractive lens exchange.
This term is used specifically in medical and optometric contexts to describe a modern type of prosthetic lens used in eye surgery. * After her cataract surgery, she chose a multifocal lens implant to be less dependent on reading glasses. * The ophthalmologist explained the pros and cons of a multifocal lens implant compared to a monofocal model. * A successful multifocal lens implant can correct presbyopia in addition to cataracts.
- Technical Context: The term is often used when discussing surgical options, patient outcomes, and the trade-offs between extended range of vision and potential visual side effects like halos or glare.
- As a Modifier: The term can function attributively (like an adjective) before other nouns.
- Multifocal lens implant technology has advanced significantly in the last decade.
- The patient was a good candidate for multifocal lens implant surgery.
- Multifocal IOL: A common abbreviated form (IOL = Intraocular Lens).
- Extended Depth of Focus (EDOF) IOL: A related but distinct type of lens implant that creates a single elongated focal point, often grouped with multifocal lenses in discussions.
- Monofocal lens implant: The contrasting standard lens implant that provides clear vision at only one fixed distance (usually far).
- Accommodating lens implant: A different type of IOL designed to move or change shape within the eye to focus at different distances.
- Multifocal intraocular lens (More formal/technical synonym)
- Presbyopia-correcting IOL (Broader category that includes multifocal and accommodating lenses)
- Lens replacement surgery: The general procedure for implanting an IOL.
- Cataract surgery with premium IOL: A common phrase describing the use of a multifocal, EDOF, or toric lens implant during cataract removal.
- Full range of vision: A phrase describing the goal or outcome of a successful multifocal lens implant.
A patient sees clearly both a distant clock and a book in their hands after receiving a multifocal lens implant.
- a type of lens implant that contains several rings with a common center and adjusts for near or far vision; the eye is in focus for near and far vision simultaneously
