Post-market Surveillance Analysis of Refractive Data in Users of Delivery Tyro^®, a Tyrosine-Releasing Contact Lens.

ABSTRACT:

Introduction

Myopia is a growing public health concern, particularly among young individuals. Several pharmacological and optical interventions exist to slow its progression, yet each has limitations. In January 2021, Safilens introduced the Delivery Tyro^® daily disposable contact lens, which releases hyaluronic acid, tamarind seed polysaccharide, and tyrosine, a dopamine precursor with antioxidative and cytoprotective properties.

Methods

This study analyzed post-market surveillance data collected by 55 optometrists from 241 myopic subjects (mean age, 14.73 years; mean initial spherical equivalent (SE) refraction, - 2.72 diopters [D]) over a 12-month period of bilateral Delivery Tyro^® lens use. The purpose of the analysis was to compare the observed myo
