Area of Science:

Ophthalmology
Surgical Devices
Cataract Surgery

Background:

Small pupils pose challenges during cataract surgery, potentially complicating procedures and increasing risks.
Existing pupil expansion devices may require specialized injectors, adding complexity to the surgical workflow.

Purpose of the Study:

To introduce and describe the B-HEX® Pupil Expander, a novel disposable device for pupil expansion.
To highlight the device's unique features for simplified insertion, removal, and intraoperative maneuverability.

Main Methods:

The B-HEX® Pupil Expander is a disposable, 6.5 mm flexible hexagonal device designed for pupil dilation.
It features notches and flanges that engage the iris, expanding the pupil to 5.5 mm.
The device is inserted and removed using a manipulator or micro-forceps through incisions as small as 1 mm, without requiring an injector.

Main Results:

The B-HEX® offers a thin, uniplanar design that ensures unhindered instrument movement during various stages of cataract surgery.
Its design allows for safe use even after capsulorhexis, with visible notches to avoid capsular tears.
The device is compatible with multiple cataract surgery techniques, including micro-incision cataract surgery (MICS) and femtosecond laser-assisted cataract surgery (FLACS).

Conclusions:

The B-HEX® Pupil Expander provides a safe, efficient, and versatile option for managing small pupils during cataract surgery.
Its ease of use and compatibility with minimally invasive techniques make it a valuable tool for ophthalmic surgeons.
