Initial results of trifocal diffractive IOL implantation

Graefe's Archive for Clinical and Experimental Ophthalmology, 2010
Bifocal intraocular lenses (IOL) are designed to reduce dependence on eyeglasses after surgery, but they cannot provide full range of vision, and have a drop of visual acuity in the intermediate distance. This problem may be solved with a trifocal lens, which produces three useful focal points.

Outcomes of bilateral implantation of trifocal and extended depth of focus IOLs

Vestnik oftal'mologii, 2022
In recent years, a new class of extended depth of focus (EDOF) intraocular lenses (IOLs) has become available on the market. There is only a limited number of scientific papers comparing trifocal and EDOF IOL data, and the results are often contradictory.Comparative analysis of the results of trifocal and EDOF IOL implantation in patients with ...
