Alcon Presents Comprehensive Scientific Program With 59 Abstracts at ESCRS 2022

Alcon will present extensive data during the 2022 Congress of the European Society of Cataract and Refractive Surgery (ESCRS), a hybrid event taking place both virtually and in Milan, Italy, September 16-20. The official program will feature 59 abstracts, with more than 30 focused on Alcon’s IOL technologies, notably AcrySof IQ Vivity. Additional data will be presented on Argos Biometer and Active Sentry Handpiece, which are part of the Alcon Vision Suite – Alcon’s products, digital solutions and services ecosystem. Data on one of Alcon’s latest additions, the Hydrus Microstent, will also be presented.

“Alcon is proud to have such a significant scientific presence at the ESCRS Congress in Milan that spans across our portfolio,” said Michel Letort, EMEA Head of Medical Affairs at Alcon. “The data presented continues to demonstrate that the efficiency of our equipment and implantables support surgeons in delivering brilliant patient outcomes.”

Reduced spectacle dependence and high patient satisfaction with AcrySof IQ Vivity IOL continue with the first and only presbyopia-correcting IOL with wavefront-shaping technology and a clinically proven, exceptionally low rate of visual disturbances. [1-3] Key data continues to demonstrate that Vivity delivers an extended range of vision while maintaining a visual disturbance profile comparable to the best-in-class AcrySof® IQ monofocal.[1-2]

Second interim analysis of the Vivity Registry Study, a real-world, multi-country, ambispective, non-comparative, open-label, non-interventional study/registry conducted in Europe, New Zealand and Australia, demonstrated:

• 92.9% and 88.7% of patients reported “never” or “rarely” using eyeglasses to see at distance and intermediate in bright light;*‡

• Uncorrected binocular vision was of 20/20 at distance, 20/25 at intermediate and 20/32 at near;*

• More than 91% of the patients did not report any visual disturbances, halos, glare or starbursts;*†

• 91.4% of the patients were satisfied with their sight.*§

Additional sub-group analyses per country, per site, as well as by comorbidities, in post-corneal refractive patients and mini-monovision will be presented at the scientific sessions during ESCRS congress in Milan.

Other key presentations on AcrySof IQ VivityTM IOL include:

• Clinical impact of residual astigmatism in patients with a novel presbyopia-correcting intraocular lens by Rementeria L, et al.

• Clinical performance of the extended range of vision intraocular lens Vivity TM in patients with previous corneal laser refractive surgery by Carreras H, et al.

• Comparison of near visual acuity using a non-diffractive extended depth-of-focus IOL with different target refractions by Mayer W, et al.

• Visual acuity and spectacle independence of patients implanted with three extended depth of focus IOLs or a monofocal one as the control by Del Pozo Lérida S, et al.

• Visual disturbances produced after the implantation of three extended-depth-of-focus intraocular lenses versus one monofocal lens by Guarro M, et al.

Several additional abstracts address elements of the Alcon Vision Suite offering surgeons enhanced efficiency and accuracy to help improve patient outcomes.[4-8]

In diagnostics, the Argos Biometer demonstrated a lowest refractive prediction error versus comparable Optical coherence tomography and optical low coherence reflectometry biometers and higher acquisition rate in eyes with dense cataracts when compared to an optical biometer.[11-12]. The acquisition rate in the dense cataract population for Argos was 89% compared to another biometer at 59% (P=0,0047).[11] Another study in eyes with dense cataracts shows that Argos Biometer achieves 100% acquisition rate of the axial length compared to 66.66% for a different biometer.[12]

In addition, several investigators demonstrated that the built-in fluidics pressure sensor in the Active Sentry Handpiece improved phacoemulsification efficiency by reducing the amount of energy used during the procedures (CDE 6,2 vs 6,7; P=0.0001) and shortened their duration (total ultrasound time 48.0 vs 57.0; P<0.0001) compared to traditional phacoemulsifier-based sensors.[14]

Sustained safety and efficacy of the Hydrus Microstent through 5-year follow-up of a cohort of patients enrolled in HORIZON Clinical Study. The longest, continuous follow-up of a minimally invasive glaucoma surgery (MIGS) device reveals significantly reduced medication use in the treated group compared to cataract surgery alone (66% vs 46%; p≤0.001), as well as a reduction in the frequency of further glaucoma surgeries.[15]
