Comparison of 1-site versus 2-site phacotrabeculectomy

Area of Science:

• Ophthalmology
• Surgical Innovation
• Glaucoma Management

Background:

• Glaucoma filtration and phacoemulsification surgery are common treatments for glaucoma.
• Optimizing surgical techniques is crucial for improving patient outcomes.
• Comparing single-site versus two-site approaches may reveal differences in efficacy and safety.

Purpose of the Study:

• To compare the efficacy of 1-site versus 2-site combination glaucoma filtration and phacoemulsification surgery.
• To evaluate differences in visual acuity, intraocular pressure (IOP), and medication requirements.
• To determine if surgical site number impacts glaucoma treatment outcomes.

Main Methods:

• A retrospective case-control study design was employed.
• 64 eyes (59 patients) undergoing 2-site phacotrabeculectomy were compared to 71 eyes undergoing 1-site phacotrabeculectomy.
• Minimum follow-up was 1 year, with analysis of visual acuity, IOP, and medication use.

Main Results:

• Preoperative visual acuity, IOP, and medication requirements were similar between groups.
• At 1-year postoperative, no statistically significant differences were observed in visual acuity (P = .99).
• Mean final IOP (P = .97) and glaucoma medication requirements (P = .52) were also comparable between the 1-site and 2-site groups.

Conclusions:

• There is no statistically significant difference in outcomes between 1-site and 2-site glaucoma filtration and phacoemulsification surgery.
• Both surgical approaches yield similar results regarding visual acuity, IOP control, and medication dependence.
• The number of surgical sites does not appear to influence the long-term effectiveness of this combined glaucoma procedure.
