Summary
The new semi-automated VITE function of the VISULAS 532s laser significantly reduces pain during retinal photocoagulation. This advanced laser treatment also decreases procedure time by one-third, improving patient compliance.
Area of Science:
- Ophthalmology
- Medical Devices
- Retinal Laser Therapy
Context:
- Retinopathy of various origins requires peripheral laser treatments.
- Conventional single-spot retinal coagulation can be time-consuming and painful.
- The VISULAS 532s laser offers semi-automated photocoagulation with short pulse durations.
Purpose:
- To evaluate the efficacy and patient experience of the semi-automated VITE function compared to conventional laser coagulation.
- To assess pain levels and treatment duration in patients undergoing retinal laser therapy.
Summary:
- A prospective randomized study compared conventional (Group A) and semi-automated VITE (Group B) laser treatments in 101 patients.
- Group B (VITE function, 20 ms pulse duration) reported significantly less pain (1.3% vs. 46.0%) and reduced treatment time (by one-third) compared to Group A.
- Both groups achieved similar moderate coagulation effects without complications.
Impact:
- The semi-automated VITE function enables nearly painless retinal coagulation.
- Reduced treatment times enhance patient compliance and potentially allow for more efficient clinical workflows.
- Further long-term studies are needed to confirm the regression of proliferative changes.
