The quadrate suture. A new technique for temporary intraoperative mydriasis

Area of Science:

• Ophthalmology
• Surgical Techniques
• Ophthalmic Devices

Background:

• Maintaining adequate pupillary dilation is crucial for safe and effective intraocular surgeries.
• Traditional methods for pupillary dilation may involve pharmacological agents or specialized surgical equipment.
• Minimally invasive and atraumatic techniques are continuously sought to improve patient outcomes.

Purpose of the Study:

• To describe a novel, simple, and atraumatic closed suturing technique for achieving and sustaining intraoperative pupillary dilation.
• To present a method that utilizes readily available surgical materials, eliminating the need for specialized instruments.

Main Methods:

• A closed suturing technique is detailed, employing standard sutures, needles, and syringes.
• The technique is designed to be performed without the necessity of paracentesis or sclerotomy incisions.
• The method focuses on creating and maintaining pupillary aperture throughout the surgical procedure.

Main Results:

• The described technique provides a simple, quick, and effective means of intraoperative pupillary dilation.
• The method is atraumatic, minimizing potential damage to ocular tissues.
• The use of common surgical supplies simplifies the procedure and reduces costs.

Conclusions:

• This closed suturing technique presents a valuable alternative for achieving and maintaining pupillary dilation in ophthalmic surgery.
• The technique's simplicity, effectiveness, and atraumatic nature make it a practical option for surgeons.
• Elimination of specialized equipment and invasive incisions enhances surgical safety and efficiency.
