The Protective Impact of TheaLoz Duo Eyedrop on the Ocular Surface in Hand-Held Console and Computer Game Users

What this Trial Is About

Digital gamers who use handheld consoles and computers often experience damage and symptoms related to dryness of the eye surface due to excessive screen time. This research evaluates whether a lubricating eyedrop called TheaLoz Duo can protect the eye surface from dryness and relieve symptoms of dry eye disease in this population. The study is a randomized, outcome assessor-masked, cross-over clinical trial conducted at Aston University to address this growing concern among gamers worldwide. Participants will use TheaLoz Duo eyedrops containing trehalose and sodium hyaluronate four times daily for one month during one treatment period, and have no eyedrops during the other month. They will be assigned randomly to start either with the eyedrop or the control (no eyedrops) for one month, then switch to the other condition for the following month. The study includes three visits spaced one month apart, during which clinical assessments will be performed. During each visit, participants will undergo routine examinations of the front of the eye to monitor symptoms and signs of dry eye disease. Measurements will include changes in Ocular Surface Disease Index scores and other eye health indicators over the two months. Participants must be able to apply the eyedrops themselves and attend all three visits. The study aims to provide valuable data to improve eye care for gamers by carefully tracking multiple eye health outcomes and symptoms throughout the study period.
