Professor Gus Gazzard is joined by Ahmad Elsahn to delve into the use of excimer laser technology and its impact in shifting mindsets towards more interventional strategies for glaucoma patients. They provide insights into the distinct characteristics of the excimer laser, and discuss the safety and efficacy of the treatment.

Episode 2: Spotlight on Excimer Lasers
- 11 March 2024
Key Takeaways
- Characteristics of Excimer Lasers: The excimer laser differs from other optical lasers due to its formation process involving a noble gas and a halogen, resulting in ultraviolet laser emission with high precision and no thermal effect.
- High Precision: Excimer laser precision and non-thermal approach protects the integrity of adjacent tissues and collector channels with minimal scar formation and inflammatory responses.
- Cold Laser Technology: Contrary to common laser associations with heat, excimer laser is a non-thermal laser that creates controlled openings in the trabecular meshwork to facilitate aqueous outflow, thereby reducing IOP.
- Efficacy and Long-Term Safety: Excimer trabeculotomy has demonstrated effectiveness in reducing intraocular pressure and is backed by long-term follow-up data [1-4] and basic underpinning clinical research, showing promising results in terms of safety and pressure-lowering effects.
