Summary

The triple procedure for cataract and glaucoma shows initial success in lowering intraocular pressure (IOP) and improving vision. However, long-term IOP control may decrease over time, questioning the procedure

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Glaucoma Management

Background:

  • Cataract and glaucoma frequently coexist, necessitating combined surgical approaches.
  • The triple procedure, combining cataract extraction, IOL implantation, and trabeculectomy, is used for these cases.
  • Long-term efficacy of the triple procedure, particularly for intraocular pressure (IOP) control, requires further investigation.

Purpose of the Study:

  • To evaluate the long-term outcomes of the triple procedure in patients with coexisting cataract and glaucoma.
  • To assess changes in intraocular pressure (IOP), visual acuity, and medication usage post-surgery.
  • To identify factors influencing the long-term success of IOP control.

Main Methods:

  • Retrospective study of 93 eyes undergoing cataract extraction, IOL implantation, and trabeculectomy.

  • Data collected over a ten-year period with a mean follow-up of 32.4 months.
  • Analysis of pre- and postoperative intraocular pressure (IOP), best-corrected visual acuity (BCVA), and medication requirements.

    • Main Results:

    • Mean postoperative IOP was significantly lower than preoperative levels, with reduced medication use.
    • One year post-surgery, 60% of eyes achieved a BCVA of 20/40 or better, with an average visual gain of 3.8 Snellen lines.
    • Eyes operated on four or more years prior showed a higher percentage of IOP exceeding 22 mm Hg and poorer IOP control, especially without medication.

    Conclusions:

    • The triple procedure offers initial benefits in visual acuity and IOP reduction for coexisting cataract and glaucoma.
    • A decrease in IOP control effectiveness over extended postoperative periods was observed.
    • The long-term sustainability of IOP control achieved by the triple procedure warrants further study and potential re-evaluation.
