Abstract Details

Purpose:

To report the first results of the single-knot sewing-machine suture, an approach to the correction of iridodialysis presented by our group in the Journal of Cataract and Refractive Surgery in 2016.

Setting:

Department of Ophthalmology, Centro Hospitalar e Universitário de Coimbra - CHUC, Coimbra, Portugal

Methods:

Consecutive case series of patients with traumatic iridodialysis who underwent single-knot sewing-machine suture, a new technique with single-thread single-knot suture in the managing of iridodialysis. All patients were evaluated for surgical indications, pre- and postoperative refractive status (visual acuity and corneal astigmatism), postoperative stability for implantation of an iris-fixated IOL and endothelial cell density. Visual acuity and intra ocular pressure were registered in clinical visits on 1st week, 1st month and biannually.

Results:

We included ten eyes from ten patients with post-traumatic iridodialysis of more than 30º. The included subjects underwent a surgical procedure using the single-knot sewing-machine suture. Some patients required secondary implantation of an iris-fixated IOL for correction of the refractive error. All patients presented an improvement of best corrected visual acuity with a reduction of endothelial cell density of less than 10%, in the last follow-up visit. A stable satisfactory aesthetic result was achieved in all cases, and no major complications were observed. The minimum follow-up period was 3 months and the maximum was 2 years.

Conclusions:

Single-knot sewing-machine suture is a safe and effective technique for iridodialysis’ repair, being a simple and innovative substitute to the methods currently described in the medical literature.
