Clinical application progress of monofocal intraocular lens in cataract treatment

Abstract:

Cataract extraction combined with intraocular lens implantation is a standard method for treating cataracts, significantly improving patients' vision and quality of life. In this process, the personalized selection of intraocular lenses plays a crucial role in the surgical outcome. Traditional monofocal intraocular lenses provide good distance vision but often have issues with intermediate vision, requiring patients to rely on glasses for correction in daily life. In contrast, multifocal intraocular lenses can meet vision needs at different distances, but are often accompanied by adverse reactions such as halos and glare, affecting the patient's visual experience. In recent years, new types of monofocal intraocular lenses have made significant progress in improving intermediate vision, with relatively fewer side effects. This article aims to review the different types, optical characteristics, and clinical efficacy of monofocal intraocular lenses, providing a reference for ophthalmologists in selecting suitable lenses for patients.
