An ocular fixation device for freehand pars plana vitrectomy

Area of Science:

• Ophthalmology
• Surgical Instrumentation
• Microsurgery

Background:

• Freehand vitrectomy requires stable ocular support.
• Existing methods may lack adequate control over ocular movement during surgery.

Purpose of the Study:

• To describe an adapted stereotaxic micromanipulator for ocular support and stabilization during vitrectomy.
• To provide surgeons with adjustable ocular mobility and stability.

Main Methods:

• Adaptation of a stereotaxic micromanipulator.
• Incorporation of a head immobilization baseplate.
• Development of an ocular fixation arm assembly using a Flieringa ring for scleral attachment.

Main Results:

• The device provides both flexible and rigid ocular support.
• Allows for surgeon-controlled ocular mobility or stabilization as needed.
• Facilitates enhanced precision during freehand vitrectomy.

Conclusions:

• The adapted micromanipulator effectively supports and stabilizes the eye during vitrectomy.
• Offers a valuable tool for improving surgical control and potentially patient outcomes.
