INTRODUCTION: The aim of this prospective study is to verify, in terms of both early postoperative complications and intraocular pressure (IOP) outcomes, the performance of a scleral flap removable suture. MATERIALS AND METHODS: Sixty-six patients that underwent trabeculectomy were randomly divided into two groups: in the first group (group A, 33 eyes) a standard fornix-based trabeculectomy was performed by using a conjunctival chain suture. In the second group (group B, 33 eyes) the same technique was performed with the additional employment of a new removable suture to the scleral flap. The patients were followed-up for 12 months. RESULTS: After 1 year the mean IOP was 16.58 mmHg (+/-3.73 mmHg) in group A, and 16.12 mmHg (+/-4.21 mmHg) in group B; statistical analysis did not show significant differences between the two groups (P = 0.19). Early postoperative hypotony and shallowing of the anterior chamber were significantly more frequent after standard trabeculectomy than after trabeculectomy using the removable suture (P < 0.02). CONCLUSIONS: The employment of a fornix-based conjunctival chain suture for the flap allows the use of the removable scleral flap suture, which has proved very effective in preventing insufficient flap resistance with aqueous overdrainage and hypotony, and which is also easy to apply and to remove. Compared with standard trabeculectomy, this device has proved to have similar IOP-lowering efficacy, together with a lower rate of early postoperative complications.

MATERIALS AND METHODS: Sixty-six patients that underwent trabeculectomy were randomly divided into two groups: in the first group (group A, 33 eyes) a standard fornix-based trabeculectomy was performed by using a conjunctival chain suture. In the second group (group B, 33 eyes) the same technique was performed with the additional employment of a new removable suture to the scleral flap. The patients were followed-up for 12 months. RESULTS: After 1 year the mean IOP was 16.58 mmHg (+/-3.73 mmHg) in group A, and 16.12 mmHg (+/-4.21 mmHg) in group B; statistical analysis did not show significant differences between the two groups (P = 0.19). Early postoperative hypotony and shallowing of the anterior chamber were significantly more frequent after standard trabeculectomy than after trabeculectomy using the removable suture (P < 0.02).
