A new aspiration tip and suction distributor enhance cataract surgery by enabling two-handed removal of residual lens cortex. This device improves aspiration, particularly at the challenging 12 o'clock position.

Area of Science:

Ophthalmology
Surgical Instrumentation

Background:

Cataract surgery often requires efficient removal of residual lens cortex.
Accessing and aspirating cortex at the 12 o'clock position can be challenging with standard irrigation-aspiration tips.

Purpose of the Study:

To introduce and evaluate a novel aspiration tip and suction distributor for cataract surgery.
To assess the device's efficacy in two-handed aspiration of residual lens cortex, especially at the 12 o'clock position.

Main Methods:

Development of a new aspiration tip and suction distributor.
Utilizing the device in two-handed phacoemulsification procedures.
Comparing aspiration effectiveness with standard irrigation-aspiration tips.

Main Results:

Related Experiment Videos

The new instruments facilitate two-handed aspiration of residual lens cortex through existing incisions.
Effective removal of cortex lentis at the 12 o'clock position was achieved.
The device offers an advantage over irrigation-aspiration tips alone for specific cortex removal tasks.

Conclusions:

The developed aspiration tip and suction distributor improve residual cortex removal during cataract surgery.
This innovation enhances surgical efficiency and addresses challenges in aspirating cortex at difficult locations.
