Summary

Phacoemulsification surgery in eyes with chronic angle closure glaucoma and a filtering bleb is achievable. This study shows it can be done safely with slight technique modifications, maintaining bleb function and improving vision.

Area of Science:

  • Ophthalmology
  • Glaucoma Surgery
  • Cataract Surgery

Background:

  • Chronic angle closure glaucoma (CACG) often requires surgical intervention.
  • Functional filtering blebs are crucial for managing intraocular pressure (IOP) in CACG patients.
  • Cataract surgery in these eyes presents unique challenges.

Purpose of the Study:

  • To evaluate the outcomes of phacoemulsification in eyes with CACG and a pre-existing functional filtering bleb.
  • To assess the safety and efficacy of this combined surgical approach.
  • To determine the impact on bleb function and visual acuity.

Main Methods:

  • A prospective study of 60 eyes from 44 patients with CACG and functional filtering blebs.
  • Patients had controlled IOP (

  • Phacoemulsification with in-the-bag intraocular lens implantation via a clear corneal tunnel was performed.

    • Main Results:

    • Surgical complications included iris trauma (18.33%), corneal edema (11.66%), and others, but visual acuity improved in all cases.
    • Postoperative IOP remained statistically insignificant (P > 0.05) compared to preoperative levels.
    • A statistically significant increase in central anterior chamber depth was observed (P = 0.002).

    Conclusions:

    • Phacoemulsification in eyes with CACG and a functional filtering bleb is technically demanding.
    • With specific technique modifications, the procedure can be safely performed.
    • The functioning of the filtering bleb is maintained post-surgery.
