Summary
Combined phacoemulsification-trabeculectomy effectively prevents early postoperative increases in intraocular pressure (IOP) in cataract patients with glaucoma. This surgical approach offers protection against rapid IOP spikes following surgery.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Glaucoma Management
Background:
- Cataract surgery can lead to intraocular pressure (IOP) spikes.
- Patients with co-existing glaucoma are at higher risk.
- Effective IOP management is crucial post-surgery.
Purpose of the Study:
- To evaluate the efficacy of combined phacoemulsification-trabeculectomy.
- To assess the prevention of early postoperative IOP elevations.
- To compare outcomes with phacoemulsification alone.
Main Methods:
- Prospective cohort study of 80 patients.
- 36 underwent combined surgery; 44 had phacoemulsification alone.
- Standardized surgical technique by one surgeon.
Main Results:
- At 4 hours post-op, 5.5% of combined group had IOP > 30 mmHg vs. 22.7% in phacoemulsification-only group (P < .05).
- No significant IOP difference between groups at 1 and 7 days.
- Intervention rates and complications were documented.
Conclusions:
- Combined phacoemulsification-trabeculectomy demonstrates efficacy in preventing early IOP elevations.
- This approach may be beneficial for cataract patients with uncontrolled glaucoma.
- Findings may guide surgical decisions for patients with visual field or optic nerve compromise.
