AIMS To calculate the diameter of halos perceived by patients with multifocal intraocular lenses (IOLs) and to stimulate halos in patients with refractive multifocal IOLs in a clinical experiment.

Celebrating 75 years of intraocular lens advancements that have improved care for millions of cataract patients. On November 29, 1949, Sir Harold Ridley performed a surgical procedure to replace a ...

The Health Insurance Corp. (PhilHealth) has increased its coverage for patients in need of cataract surgery and the insertion ...

The results suggest that this IOL model provides accurate refractive outcomes and good visual acuity at distance, intermediate and near. Other performance metrics evaluated, such as optical quality ...

Intraocular lenses are artificial lenses implanted to replace the natural lens during cataract ... Traditional monofocal lenses primarily correct vision at a single distance. However, innovations in ...

In this Healio Video Perspective from Hawaiian Eye 2025, Jeffrey Whitman, MD, of Key-Whitman Eye Center, discusses the positive impact of the Tecnis Odyssey IOL on his practice.

Intraocular Lens (IOL): An artificial lens implanted in the eye to replace the natural lens that has become cloudy due to cataracts. Corneal Incision: A surgical cut made in the cornea (the clear ...

A critical aspect of this surgery is the accurate calculation of the IOL power, which determines how well the lens will focus light onto the retina. Recent research has focused on improving the ...

The most common type of lens is called a monofocal IOL, which has one focusing distance—close, medium, or distance vision. On the other hand, multifocal IOLs provide both distance and near focus ...

Laser arcuate keratotomy is not a superior approach to refractive astigmatism correction compared with toric IOL implantation.

The majority of the lenses currently implanted in North America are monofocal with a power chosen to restore good distance vision ... not be corrected with an intraocular lens such as astigmatism.
