Open ring-shaped guider for circular continuous curvilinear capsulorhexis during cataract surgery

Area of Science:

• Ophthalmology
• Surgical Instrumentation

Background:

• A new poly(methyl methacrylate) open-loop caliper for capsulorhexis is presented.
• This tool aims to improve capsulorhexis characteristics during cataract surgery.

Purpose of the Study:

• To introduce and evaluate a novel open-loop caliper for optimizing capsulorhexis.
• To assess the ease of use and effectiveness of the caliper in achieving ideal capsulorhexis.

Main Methods:

• The open-loop caliper, made of poly(methyl methacrylate), is used during cataract surgery.
• It is inserted onto the anterior capsule after filling the anterior chamber with an ophthalmic viscosurgical device.
• The caliper is removed after the continuous curvilinear capsulorhexis is created.

Main Results:

• The caliper optimizes capsulorhexis shape, size, and centration.
• The open-loop design facilitates easy insertion and removal through small incisions.
• It enables surgeons to achieve ideal and consistently circular capsulorhexis.

Conclusions:

• The described open-loop caliper is an effective tool for improving capsulorhexis during cataract surgery.
• Its design offers advantages in terms of ease of use and achieving superior capsulorhexis outcomes.
