Summary

This study combined cataract surgery with trabeculectomy, achieving good intraocular pressure control without medication in most cases. Visual acuity improved, showing better drainage for glaucoma patients.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Glaucoma Research

Background:

  • Cataract and glaucoma are leading causes of vision loss.
  • Combined procedures aim for simultaneous treatment.
  • Trabeculectomy efficacy can be influenced by incision type.

Purpose of the Study:

  • To evaluate a combined extracapsular cataract extraction and trabeculectomy technique.
  • To assess intraocular pressure control and visual acuity outcomes.
  • To compare trabeculectomy drainage with previous methods.

Main Methods:

  • Retrospective analysis of 35 cases.
  • Extracapsular cataract extraction via corneal section.
  • Combined with posterior chamber lens implant and trabeculectomy.

  • Separate incisions for cataract and glaucoma procedures.

    • Main Results:

    • 77% of patients achieved intraocular pressure control without medication.
    • Median visual acuity improved by 3.5 lines at one year.
    • Improved trabeculectomy drainage observed compared to corneoscleral incisions.
    • Poorer visual acuity gains in patients with severe preoperative visual field loss.

    Conclusions:

    • Combined cataract extraction and trabeculectomy is effective for IOP control.
    • Corneal section technique enhances trabeculectomy drainage.
    • Visual outcomes are influenced by preoperative visual field status.
