Definition

Noun: A monofocal IOL is a type of intraocular lens implanted after cataract surgery. It is designed with a single, fixed focal point, typically set to provide clear vision for one specific distance, most commonly for distance vision.

Usage

This term is used in medical contexts, specifically in ophthalmology, to describe a standard type of lens replacement used in cataract surgery. * The surgeon recommended a monofocal IOL to correct his distance vision after the cataract removal. * While a monofocal IOL provides excellent clarity at one distance, patients often still require glasses for near tasks like reading.

Advanced Usage

• Contrast with other IOL types: The term is often used in contrast to "multifocal IOL" or "accommodating IOL," which are designed to provide clear vision at multiple distances.
  • The patient chose a monofocal IOL over a multifocal option due to concerns about potential visual side effects like halos.
