Trabeculectomy with a Kelly Descemet membrane punch
1Department of Ophthalmology, Yamaguchi University School of Medicine, Japan.
Summary
A modified trabeculectomy using the Kelly Descemet membrane punch and Mitomycin C (MMC) resulted in no severe shallow anterior chambers in 100 patients. This technique offers a safe alternative for glaucoma surgery.
Area of Science:
- Ophthalmology
- Glaucoma Surgery
- Surgical Innovation
Background:
- Trabeculectomy is a common glaucoma surgery.
- Severe shallow anterior chamber is a potential complication.
- Mitomycin C (MMC) is frequently used to enhance surgical outcomes.
Purpose of the Study:
- To evaluate a modified trabeculectomy technique using the Kelly Descemet membrane punch.
- To assess the safety and efficacy of this modified procedure in preventing shallow anterior chambers.
Main Methods:
- The Kelly Descemet membrane punch was used to excise small limbal tissue sections (0.25 x 0.30 mm) beneath the scleral flap.
- Mitomycin C (MMC) was applied during the procedure.
- A retrospective review of 100 consecutive cases was conducted.
Main Results:
- None of the 100 patients developed severe shallow anterior chambers within ten days post-surgery.
- The punch facilitated easy excision of limbal tissue.
Conclusions:
- The modified trabeculectomy with the Kelly Descemet membrane punch and MMC is a safe and effective technique.
- This approach may reduce the risk of severe shallow anterior chambers in glaucoma surgery.
