Summary
This new surgical technique for pterygium removal minimizes bleeding and eye movement. It uses minimal anesthesia and a disposable device, simplifying the procedure and aiding conjunctival graft harvesting.
Area of Science:
- Ophthalmology
- Surgical Techniques
Background:
- Pterygium excision presents surgical challenges including bleeding and patient eye movement.
- Effective management requires techniques that address these common issues.
Purpose of the Study:
- To present a novel surgical technique for pterygium excision.
- To overcome the primary challenges of bleeding and eye movement during the procedure.
Main Methods:
- The technique employs minimal anesthesia (topical and subconjunctival).
- A disposable speculum and suction ring are utilized.
- The speculum design enhances exposure of the superior bulbar conjunctiva.
Main Results:
- The described method effectively controls bleeding during pterygium dissection.
- It minimizes involuntary eye movements, improving surgical precision.
- Facilitates efficient harvesting of conjunctival autografts for reconstruction.
Conclusions:
- This technique offers a solution to major challenges in pterygium surgery.
- It provides a simpler, safer, and more effective approach to pterygium excision and reconstruction.
