A Frag Bag for Efficient Removal of Dislocated Nuclear Material

Area of Science:

• Ophthalmology
• Surgical Innovation
• Retinal Surgery

Background:

• Retained nuclear material in the vitreous cavity is a complication of cataract surgery, ocular trauma, or lens dislocation.
• Current methods for removal can pose risks to the retinal surface.

Purpose of the Study:

• To introduce a novel instrument, the "Frag Bag", for the safe and efficient removal of dislocated nuclear material during vitrectomy.
• To evaluate the potential benefits of the Frag Bag in pars plana lensectomy procedures.

Main Methods:

• A retractable nitinol basket, the "Frag Bag", originally designed for urology, was adapted for ophthalmic use.
• The instrument was utilized during vitrectomy surgery to retrieve larger pieces of retained nuclear material through a 23-gauge port.

Main Results:

• The Frag Bag facilitated stabilization and softening of nuclear material in the mid-vitreous.
• This allowed for safer and more efficient removal by the vitreous cutter, minimizing proximity to the retina.

Conclusions:

• The Frag Bag offers a potentially safer and more efficient method for managing retained nuclear material during vitrectomy.
• Its use may reduce the need for a phacofragmatome and decrease intraoperative risks to the retina.
