Flapless Intrascleral Knotting Technique for Suture Fixation of Intraocular Implants.

PURPOSE: We will describe a flapless/grooveless/pocketless and minimally invasive technique for scleral suture fixation of intraocular implants.

METHODS

After introducing the suture into the eye, the two ends of the suture were left exterior to the globe, the free end and the end connected to a curved needle (the needle side). A back-and-forth intrascleral suture passage was performed with the aid of a curved needle. The suture was thus supported by adequate scleral tissue. The suture was fixated to the sclera by knotting it into the sclerotomy. The ends of the suture were finally anchored intrasclerally with the aid of a 30-gauge needle.

RESULTS

The technique was used in 15 eyes of 15 patients. The mean postoperative follow-up period was 9.1 ± 4.6 months. Postoperatively, the intraoperative lenses of all the eyes remained well-positioned and stable. The postoperative visual acuities for all of the eyes were also improved. No suture erosion, suture loosening, hypotony, scleral atrophy, chronic inflammation, retinal tears, and/or detachments were observed within the follow-up period.

CONCLUSION

The present technique provides minimal surgical invasion for the scleral suture fixation of intraocular implants.
