Vacuum rhexis - A novel capsulorhexis technique for white cataracts

Area of Science:

• Ophthalmology
• Surgical Techniques

Background:

• White and intumescent cataracts pose challenges during capsulorhexis.
• Standard capsulorhexis techniques risk radial tears and the "Argentinian flag sign".

Purpose of the Study:

• To describe a novel vacuum rhexis technique for managing white and intumescent cataracts.
• To demonstrate the efficacy of vacuum rhexis in achieving successful continuous curvilinear capsulorhexis (CCC).

Main Methods:

• A 24-gauge bent cannula attached to a 10-ml syringe was used for vacuum rhexis.
• The technique involves lifting and catching the capsular flap with the cannula.
• Manual suction control and circumferential movement complete the capsulorhexis.

Main Results:

• The vacuum rhexis technique maintained excellent anterior chamber stability.
• No leakage was observed, and the bent cannula provided a good fulcrum for movement.
• The technique successfully created adequate-sized CCC in challenging cataracts.

Conclusions:

• Vacuum rhexis is a novel, effective technique for performing CCC in white and intumescent cataracts.
• This method offers consistent and predictable outcomes with a single port.
• It requires no specialized surgical instruments, simplifying the procedure.
