Short-term outcomes of Tanito microhook ab interno trabeculotomy combined with phacoemulsification in primary open-angle glaucoma - A pilot study
Abstract
Purpose: The aim of the study was to assess the early postoperative efficacy and safety of Tanito microhook (TMH) ab interno trabeculotomy combined with phacoemulsification in patients with primary open-angle glaucoma (POAG).
Methods: This prospective interventional study was conducted on consecutive patients with visually significant cataract and mild-moderate POAG. All patients underwent a temporal clear corneal phacoemulsification combined with TMH ab interno trabeculotomy. Postoperative evaluation was done on day 1, 1 month, and 3 months. The outcome measures included intraocular pressure (IOP) at different follow-ups and postoperative complications.
Results: In total, 30 eyes of 30 patients were included in the study. There were 16 (53.3%) females and 14 (46.7%) males with a mean age of 62.63 ± 6.7 years. The mean IOP reduced from 23.57 ± 1.65 to 17.33 ± 2.84 at 3 months ( P < 0.001). All eyes had a corrected distance visual acuity ≥6/9 at 1 month postoperatively. Postoperative complications included corneal stromal edema in eight (26.7%) eyes, hyphema in four (13.3%) eyes, and IOP spike in one (3.3%) eye.
Conclusion: TMH ab interno trabeculotomy combined with phacoemulsification in patients with mild-moderate POAG is an effective and safe procedure with fewer complications.
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 30 participants or records.
