    Argon laser intraocular photocoagulation during vitreous surgery is safe and effective for treating retinal breaks and performing panretinal photocoagulation. This new technique simplifies treatment, avoiding complications associated with postoperative eye conditions.

    Area of Science:

    • Ophthalmology
    • Surgical Technology
    • Laser Medicine

    Background:

    • Argon laser photocoagulation is crucial for treating retinal conditions.
    • Traditional methods face challenges with intraoperative application and media opacity.

    Purpose of the Study:

    • To evaluate the safety and efficacy of intraocular argon laser photocoagulation during vitreous surgery.
    • To assess a novel operative contact lens for this procedure.
    • To examine the histopathologic effects of laser lesions in a primate model.

    Main Methods:

    • Twenty patients underwent intraocular argon laser photocoagulation using a new operative contact lens during vitreous surgery.
    • Phakic patients with gas-filled eyes were included.
    • Five rhesus monkeys were used for histopathologic assessment at various power settings.

    Main Results:

    • The intraoperative technique was performed without complications in all twenty patients.
    • The new contact lens facilitated controlled, rapid laser application at a safe distance.
    • Histopathologic evaluation in monkeys provided insights into laser lesion characteristics.

    Conclusions:

    • Intraoperative argon laser photocoagulation during vitreous surgery is a safe and effective technique.
    • The novel contact lens enhances precision and safety.
    • This approach overcomes limitations of treating through hazy postoperative media.
