Long-term Effectiveness of Trabectome (Ab-interno Trabeculectomy) Surgery

J Curr Glaucoma Pract. 2018 Sep-Dec;12(3):119-124. doi: 10.5005/jp-journals-10028-1256.

Abstract

Aim: To evaluate the long-term safety and efficacy of ab-interno trabeculectomy with trabectome for the treatment of glaucoma.

Materials and methods: Data collected for 339 eyes which included demographics, intraocular pressure (IOP) measurements using Goldmann applanation tonometry, best-corrected visual acuity (BCVA), visual field results, optic nerve status, gonioscopic findings, prior glaucoma procedures, number of glaucoma medications and pain level. The main data points of interest were preoperative IOP vs. postoperative IOP and BCVA, medication use, pain status, and complications.

Results: Of the 339 eyes that underwent trabectome, we found a statistically significant reduction in IOP (p < 0.01) at final follow-up (average = 18.35 months) of nearly 23%, with a complication rate of 5.86%. Furthermore, this reduction was maintained up to 8 years post procedure. LogMAR visual acuity was significantly improved in 69% of eyes at the final visit (p < 0.05), while only 1.77% of cases saw a significant reduction. Based on these findings, we determined a success rate of around 80% to 100 months following trabectome.

Conclusion: Trabectome is a safe and effective long term for most forms and severities of glaucoma.
