Modified 360-degree suture trabeculotomy combined with phacoemulsification and intraocular lens implantation for glaucoma and coexisting cataract.

PURPOSE

To assess the efficacy and safety of a modified 360-degree suture trabeculotomy combined with a cataract surgery technique in patients with glaucoma and coexisting cataract.

SETTING

Hokkaido University Hospital, Sapporo, Japan.

DESIGN

Retrospective case series.

METHODS

Medical records of patients with glaucoma having a modified 360-degree trabeculotomy combined with cataract surgery (Group 1) were reviewed. Another group of patients who had the modified 360-degree suture trabeculotomy alone served as controls (Group 2).

RESULTS

Both groups comprised 46 patients. In each group, eyes were diagnosed with primary angle-closure glaucoma in 2 eyes, primary open-angle glaucoma in 24 eyes, exfoliation glaucoma in 4 eyes, uveitic glaucoma in 15 eyes, and steroid glaucoma in 1 eye. The mean preoperative intraocular pressure (IOP) values were 27.2 mm Hg ± 7.3 (SD) on 3.0 ± 0.5 medications in Group 1 and 27.7 ± 10.7 mm Hg on 2.9 ± 0.6 medications in Group 2. Twelve months after surgery, the mean IOPs were 13.4 ± 3.7 mm Hg on 0.8 ± 1.1 medications in Group 1 and 13.9 ± 4.1 mm Hg on 0.6 ± 0.9 medications in Group 2. The success rate (<18 mm Hg) at 12 months was 89.1% and 93.5%, respectively. Major complications included transient IOP spikes (30.4% and 37.0%) and prolonged hyphema (10.9% and 6.5%) in Group 1 and Group 2, respectively.

CONCLUSION

The data showed the equivalent effects of suture trabeculotomy combined with cataract surgery and suture trabeculotomy surgery alone on postoperative safety and efficacy.
