Dry eye sufferers know the frustration of discomfort, irritation, and ongoing treatment routines. A new clinical study offers hope: a thermomechanical action (TMA) device known as Tixel C may be just as effective—and potentially more convenient—than traditional thermal pulsation methods. This blog explores the key findings of a recent multicentre, randomised study comparing Tixel to the established LipiFlow system, shedding light on what this could mean for Meibomian Gland Dysfunction (MGD) treatment.

Understanding Meibomian Gland Dysfunction (MGD)
- MGD affects up to 68% of people over 40, contributing to evaporative dry eye.
- It's caused by blockages in the meibomian glands, disrupting the tear film and leading to irritation.
- Traditional first-line therapy includes warm compresses and eyelid hygiene, but patient compliance is low.
Study Overview: Tixel vs LipiFlow
- Design: Randomised, evaluator-masked trial conducted across five U.S. sites.
- Participants: 106 adults with MGD symptoms and clinical indicators.
- Treatment Arms:
- Tixel: Three 2-weekly sessions applying localised heat via a non-contact thermal tip.
- LipiFlow: A single session using in-eye thermal pulsation.
Key Findings: Safety & Effectiveness
1. Tear Break-Up Time (TBUT)
- Both devices showed significant improvement at 4 and 12 weeks.
- Tixel was non-inferior to LipiFlow, meeting the primary study endpoint.
2. Symptom Relief (OSDI Scores)
- OSDI scores improved in both groups, with slightly greater gains in the Tixel group at 12 weeks.
3. Gland Function (MGS Scores)
- Both groups experienced notable improvements in meibomian gland function.
4. Drop Usage and Pain Scores
- Participants used fewer lubricant drops post-treatment, with mild discomfort reported in both groups.
- Pain scores were slightly higher for Tixel but remained low overall.
Why Tixel Stands Out
- Radiation-Free: Tixel uses brief thermal pulses with no radiation or gel required.
- No Eye Contact: The device doesn’t touch the ocular surface, enhancing comfort.
- Portable and Efficient: Each session takes just 2 minutes per eye.
- FDA Cleared: Tixel is now cleared for evaporative dry eye treatment in the US.
Conclusion
This clinical trial shows that Tixel is a safe and effective alternative to LipiFlow for treating MGD-related dry eye. With its non-contact design and efficient treatment time, it offers eye care professionals a compelling new tool for managing a widespread and often debilitating condition.
