Summary
Phacoemulsification combined with trabeculectomy surgery offers superior intraocular pressure (IOP) reduction compared to extracapsular cataract extraction (ECCE) for patients with coexisting cataract and glaucoma. This finding aids in managing glaucoma effectively.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Glaucoma Management
Background:
- Cataract and glaucoma often coexist, presenting a surgical challenge.
- Effective management requires addressing both conditions simultaneously.
- Ophthalmologists frequently encounter this combined surgical scenario.
Purpose of the Study:
- To compare the efficacy of two surgical approaches for combined cataract and glaucoma surgery.
- To evaluate intraocular pressure (IOP) reduction and bleb formation.
- To assess visual acuity and medication reduction post-surgery.
Main Methods:
- A comparative study involving 72 eyes with primary open-angle or pseudoexfoliation glaucoma.
- Eyes underwent combined cataract and filtration surgery.
- Two techniques were compared: planned extracapsular cataract extraction (ECCE) and phacoemulsification, both coupled with trabeculectomy and intraocular lens (IOL) implantation. Minimum follow-up was 1 year.
Main Results:
- Phacoemulsification/trabeculectomy resulted in a significantly greater mean IOP reduction (5.0 mmHg) compared to ECCE/trabeculectomy (2.9 mmHg).
- No significant differences were observed in visual acuity improvement between the groups.
- Glaucoma medication reduction was also comparable between the two surgical methods.
Conclusions:
- Combined cataract and filtration surgery utilizing phacoemulsification demonstrates superior intraocular pressure reduction.
- Phacoemulsification is a more effective technique for IOP control in combined cataract and glaucoma surgery than ECCE.
- Both techniques provide comparable visual outcomes and medication reduction.
