Perfluorohexyloctane Eye Drops vs. Sodium Hyaluronate for Video Display Terminal-Associated Dry Eye

29 juni 2026 bijgewerkt door: Jinyuan,MD, Beijing Tongren Hospital

A Prospective, Multicenter, Randomized Controlled Trial on the Efficacy and Safety of Perfluorohexyloctane Eye Drops Versus 0.1% Sodium Hyaluronate Eye Drops in the Treatment of Video Display Terminal-associated Dry Eye

This is a prospective, multicenter, open-label, randomized controlled trial designed to evaluate the efficacy and safety of perfluorohexyloctane (PFHO) eye drops (Hengqin®, Chengdu Shengdi Pharmaceutical Co., Ltd.) compared with 0.1% sodium hyaluronate eye drops in patients with video display terminal (VDT)-associated dry eye.

Participants aged 18-70 years with mild to moderate dry eye (confirmed by Chinese Dry Eye Expert Consensus 2020 criteria) who use video display terminal for more than 6 hours/day and at least 5 days/week for more than 1 year will be enrolled. A total of 159 subjects will be randomized in a 2:1 ratio to the experimental group (PFHO eye drops, n=106) or control group (0.1% sodium hyaluronate eye drops, n=53), both administered 1 drop/eye, 4 times daily (3-5 hour intervals), bilaterally, for 8 weeks.

The primary endpoint is the change from baseline in fluorescein tear film break-up time (FBUT) at Week 8. Secondary endpoints include FBUT changes at Weeks 2 and 4, standard patient evaluation of eye dryness(SPEED) questionnaire score changes, total corneal fluorescein staining (tCFS), partial blink rate (PBR), non-invasive tear film break-up time (NIBUT), lipid layer thickness (LLT), meibomian gland secretion quality score, and This is a prospective, multicenter, open-label, randomized controlled trial designed to evaluate the efficacy and safety of perfluorohexyloctane (PFHO) eye drops (Hengqin®, Chengdu Shengdi Pharmaceutical Co., Ltd.) compared with 0.1% sodium hyaluronate eye drops (Hialid®) in patients with video display terminal (VDT)-associated dry eye.
