Welcome to another edition of CEDARS/ASPENS Debates. CEDARS/ASPENS is a joint society of cornea, cataract and refractive surgery specialists, here to discuss some of the latest hot topics in ophthalmology.

The Artis Symbiose IOL provides sharp, continuous vision at all distances with fast adaptation, according to one specialist.

The American Society of Cataract and Refractive Surgery meeting moved to a virtual format this year due to the COVID-19 pandemic.

Currently available IOLs offer a wide range of options and increasing opportunities for personalized selection. The FDA approval in August 2019 of Alcon’s AcrySof IQ PanOptix trifocal IOL, the first of its kind in the U.S., further enriched the market. Although the perfect lens that satisfies all needs without compromise is not yet there, and careful case-by-case evaluation is still required, the chances of satisfying patients are much greater than in the past.

The first IOL was implanted by Sir Harold Ridley on Nov. 29, 1949, at St. Thomas’ Hospital in London. Amazing to me, it was a monofocal posterior chamber lens, or PCL, manufactured by Rayner and implanted after large-incision extracapsular cataract extraction. Sixty years later, the procedure of PCLs implanted after small-incision ECCE with the nucleus removed by phacoemulsification in more affluent countries and manually in less affluent countries remains dominant.

Patients who received the first FDA-approved trifocal IOL reported high satisfaction with the lens, but some can experience some contrast or quality diminution even with final 20/20 vision, according to a speaker at the virtual American Society of Cataract and Refractive Surgery meeting.

In this video perspective from the virtual American Society of Cataract and Refractive Surgery meeting, John A. Hovanesian, MD, FACS, discusses a study showing high patient satisfaction in those implanted bilaterally with the Alcon PanOptix trifocal IOL.
