Single wound, in situ tying technique for iris repair

Area of Science:

• Ophthalmology
• Surgical Techniques
• Iris Repair

Background:

• Iris suturing is crucial for managing various ocular conditions.
• Existing methods may involve multiple incisions or cause iris distortion.
• A need exists for a minimally invasive and precise iris suturing technique.

Purpose of the Study:

• To present a novel technique for placing and tying interrupted iris sutures.
• To demonstrate the feasibility of using a single limbal paracentesis wound for iris repair.
• To achieve precise suture placement and controlled tension without distorting the iris.

Main Methods:

• A single limbal paracentesis wound is utilized for all surgical steps.
• Interrupted sutures are placed in various iris locations.
• Sutures are tied externally using conventional knot-tying techniques.
• Suture throws are then advanced into the anterior chamber and tightened to 180 degrees.

Main Results:

• The technique allows iris suturing in virtually any iris location.
• Sutures are tied externally, preventing intraocular manipulation during knot tying.
• The iris remains in situ, avoiding stretching and distortion.
• Controlled 180-degree tension is achieved on suture ends.

Conclusions:

• This technique offers a versatile and minimally invasive approach to iris suturing.
• It preserves iris anatomy and function by avoiding distortion.
• The method simplifies iris repair through a single limbal access point.
