AB interno iridectomy combined with pars plicata lensectomy

Area of Science:

• Ophthalmology
• Surgical Techniques

Background:

• Cataract surgery, including pars plicata lensectomy and membranectomy, carries risks.
• Angle closure glaucoma is a potential complication in certain ophthalmic procedures.
• Existing surgical methods may involve risks of excessive vitrectomy.

Purpose of the Study:

• To enhance the safety of pars plicata lensectomy and membranectomy during cataract surgery.
• To develop a novel combined ab interno iridectomy and cataract surgery technique.
• To prevent angle closure glaucoma without compromising surgical outcomes.

Main Methods:

• Applied a pressure cuff to the Peyman's miniphage's soft bag to increase infusion pressure.
• Developed and utilized an ab interno iridectomy combined with pars plicata cataract surgery.
• Employed the miniphage or wide-angle cutter vitrophage for the surgical procedures.

Main Results:

• Increased infusion pressure improved the safety of lensectomy and membranectomy.
• The combined ab interno iridectomy and cataract surgery technique successfully prevented angle closure glaucoma.
• No major intraoperative or postoperative complications were observed.

Conclusions:

• The modified Peyman's miniphage technique offers enhanced safety for specific cataract surgeries.
• The novel combined surgical approach effectively prevents angle closure glaucoma.
• This technique represents a safe advancement in ophthalmic surgical procedures.
