Outline

Text

Purpose: To develop an efficient and minimally invasive traction suture method for trabeculotomy.

Method: A continuous suture was placed near the corneal limbus at the 9- or 3-o’clock position and the 12-o’clock position as a traction suture. A scleral flap was created, inverted and sandwiched between the continuous suture and the cornea, and secured in place.

Result: The traction force was distributed, making the traction suture less likely to dislodge, and a wide, flat surgical field was established. By sandwiching the scleral flap between the continuous suture and the cornea, noninvasive flap fixation and traction became possible. The corneal limbus was compressed by the continuous suture, blocking aqueous humor outflow and minimizing intraoperative aqueous humor outflow even after the ostomy. This made it possible to perform iridectomy and scleral flap suturing while maintaining the anterior chamber.

Conclusion: By performing the continuous two-point traction suture technique, trabeculotomy can be performed more easily and with less invasion.
