Toric Intraocular Lens

LAS VEGAS — In this Healio Video Perspective from the ASCRS meeting, Seth M. Pantanelli, MD, compares astigmatism treatment outcomes when using the Barrett toric and EVO toric calculators.

LAS VEGAS — In this Healio Video Perspective from the ASCRS meeting, P. Dee G. Stephenson, MD, FACS, discusses the benefits of using a toric IOL in place of a monofocal IOL when correcting low astigmatism.

AMELIA ISLAND, Fla. — In this video from Cataract Surgery: Telling It Like It Is, Mitchell C. Shultz, MD, explains his reasons for using the enVista toric IOL (Bausch + Lomb), including uniform power and extended depth of focus.

WAILEA, Hawaii — In this video from Hawaiian Eye, Elizabeth Yeu, MD, discusses four different surgical options for managing toric IOL surprises and how to determine which to use in different circumstances.

Astigmatism is the most common and most complex of refractive errors. Management requires careful analysis of many variables and personalized strategies.

I am a firm believer in correcting astigmatism at the time of cataract surgery. Nearly 40% of patients undergoing cataract surgery in the U.S. have significant astigmatism, greater than 1 D, and the prevalence increases with age.

A prospective comparative case series of 50 patients implanted bilaterally with either the toric or non-toric version of the AcrySof IQ PanOptix aspheric quadrifocal IOL from Alcon showed comparable outcomes.

Irregular astigmatism is a term often used to refer to any type of higher-order aberration that cannot be corrected with spherocylindrical lenses.

Correcting astigmatism is an important part of cataract surgery, especially as the goals of modern cataract surgery have evolved to mirror that of refractive surgery, responding to heightened expectations of patients.

Autokeratometry and topography together can be used to validate measurements when planning toric IOL placement and alignment, according to Warren E. Hill, MD.
