accommodating IOL
Noun: A type of artificial lens implanted in the eye after cataract surgery. It is designed with a flexible hinge mechanism that allows the lens to change shape slightly, enabling the eye to focus on objects at both near and far distances. This aims to mimic the natural focusing ability (accommodation) of a youthful human eye.
The term is used specifically in ophthalmology and optometry to describe this advanced intraocular lens (IOL) technology. It is a compound noun where "accommodating" describes the lens's functional property.
Examples: * After her cataract surgery, she chose an accommodating IOL to reduce her dependence on reading glasses. * The surgeon explained the benefits and risks of an accommodating IOL compared to a standard monofocal lens. * Modern accommodating IOLs represent a significant advancement in restoring a range of vision.
- The technology is often discussed in the context of presbyopia-correcting intraocular lenses, which also include multifocal and extended depth of focus (EDOF) lenses.
- Performance can be described in terms of the range of accommodation or the defocus curve it provides.
- Accommodating lens (a common shortened form in clinical settings).
- AIOL (an acronym sometimes used in medical literature).
- Intraocular lens (IOL): The general category of implanted lenses.
- Monofocal IOL: A standard IOL that provides clear vision at one fixed distance (usually far).
- Multifocal IOL: A different type of presbyopia-correcting IOL that uses concentric rings to provide multiple focal points simultaneously.
- Presbyopia-correcting IOL (a broader category that includes accommodating designs).
- Focal-shifting IOL.
- Accommodation: The eye's natural ability to change focus from distant to near objects.
- Capsular bag: The natural capsule of the eye where the IOL is implanted; its movement is essential for the function of an accommodating IOL.
- Pseudoaccommodation: A term sometimes used to describe the functional result provided by these lenses.
- a lens implant containing a hinge that allows for both near and far vision (thus mimicking the natural lens of a young person)
