    Area of Science:

    • Ophthalmology
    • Surgical Techniques

    Background:

    • Glaucoma management requires effective intraocular pressure (IOP) reduction.
    • Trabeculectomy is a common surgical procedure for glaucoma, but outcomes can vary.

    Purpose of the Study:

    • To present a modified trabeculectomy technique that customizes tissue removal based on initial IOP.
    • To evaluate the efficacy and safety of this adjusted trabeculectomy in diverse glaucoma types.

    Main Methods:

    • A trabeculectomy technique was employed, adjusting the thickness of removed sclerocorneal tissue according to pre-operative IOP.
    • The procedure was performed on 35 eyes across various glaucoma types with pre-operative pressures up to 50 mmHg.

    Main Results:

    • A single operation successfully controlled IOP without additional medication in 78.3% of cases.

  • The overall success rate, including reoperations and additional medication, reached 97.3%.
  • Complications such as hyphaema and shallow anterior chamber were observed but resolved with conservative therapy.

    • Conclusions:

    • Adjusting sclerocorneal tissue thickness in trabeculectomy is an effective method for achieving target IOP in glaucoma.
    • This technique offers a high success rate and a favorable safety profile for managing various types of glaucoma.
