In the Heritage Lecture presented at the 40th Congress of the ESCRS, noted cataract and refractive surgery pioneer Dr Lucio Buratto discussed the evolution of cataract surgery from Ridley’s first IOL to the modern foldable lenses we use today.

Bridging The Gap Between Lab And Clinic

In the editorial, Liliana Werner MD, PhD highlights JCRS’s Laboratory Science section—introduced in January 2000 as “devoted to experimental work related to cataract and refractive surgery.” The journal has since published approximately 700 articles in this section and created the Mamalis Award for the Best Laboratory Science Article, presented during the ASCRS/ESCRS annual meeting. John Zdral and associates received the first award for their article “Rotational stability of toric intraocular lenses with a newly modified capsular tension ring”, published in the April 2021 issue. Article award winners feature on a dedicated page on the JCRS website.

New Complementary Edof System

A new complementary extended depth of focus (EDOF) IOL system may yield better monocular intermediate visual acuity than the conventional trifocal lens, a new optical bench study suggests. The study compared a conventional trifocal IOL (AcrySof IQ PanOptix, Alcon) and the ARTIS Symbiose complementary IOL system (Cristalens Industrie). The patient received an ARTIS Symbiose MID with an EDOF profile favouring intermediate vision in one eye and an ARTIS Symbiose PLUS with an EDOF profile favouring near vision in the other. The MID lens produced higher MTF values than the other studied IOLs at the intermediate focus, whereas the PLUS lens outperformed the others at the near focus. The author noted the new system may yield better monocular intermediate visual acuity than the conventional lens, but further investigation is necessary.

NEW PRESSURE-SENSING PHACO HANDPIECE

The new pressure-sensing Sentry phaco handpiece for the Centurion Vision System phacoemulsification and aspiration system quickly detects IOP changes in the anterior chamber and stabilises IOP during surgery, a new study suggests. The study authors compared changes in anterior chamber depth (ACD) in freshly enucleated porcine eyes during intentional occlusion breaks with the Centurion Vision System with Active Sentry, Infiniti Vision System, and Constellation Vision System. Each group included five eyes, and the researchers observed and evaluated the ACD changes using the slit side view (SSV) method. The smallest ACD change occurred in the eyes where the Sentry phaco handpiece was used.
