Prevention of suture exposure in transscleral intraocular lens fixation: an original technique.

BACKGROUND

In this retrospective study, we evaluated our surgical outcomes of transscleral intraocular lens (IOL) fixation and introduced a simple, quick, and effective method to fixate and bury the sutures in the sclera to avoid suture exposure.

METHODS

Eyes were divided into 3 groups according to surgical technique. Half-thickness scleral flaps were prepared, and polypropylene suture ends were cut short in group 1 (12 eyes). Suture ends were left long without flaps in group 2 (47 eyes) and were buried into the scleral tunnel in group 3 (21 eyes).

RESULTS

The suture exposure rate was significantly lower in group 3 (0%) compared with group 2 (p = 0.006) and group 1 (p = 0.040). There was no significant difference in group 1 (25%) compared with group 2 (27.6%) (p = 1.000).

INTERPRETATION: Burying the suture ends into the scleral tunnel is a simple, safe, and effective technique for avoiding suture exposure in scleral-fixated IOL implantation.
