[Performance evaluation of NeoSoniX technology in cataract surgery]

Area of Science:

• Ophthalmology
• Surgical Technology
• Medical Devices

Background:

• Cataract surgery techniques have advanced significantly.
• Phacoemulsification devices with reduced ultrasound usage contribute to improved surgical outcomes.
• The NeoSoniX handpiece represents an innovation in phacoemulsification technology.

Purpose of the Study:

• To evaluate the theoretical advantages of the NeoSoniX handpiece in cataract surgery.
• To compare the performance of the NeoSoniX handpiece against a conventional ultrasound handpiece.

Main Methods:

• A retrospective analysis of 400 cataract surgeries (300 conventional, 100 NeoSoniX).
• Comparison of ultrasound time, balanced saline solution volume, and ultrasound energy percentage.
• All surgeries performed by the same surgeon using consistent techniques, with random handpiece selection.
• Analysis stratified by cataract hardness grade.

Main Results:

• NeoSoniX handpiece use resulted in significantly lower ultrasound time (p<0.000001).
• Significantly reduced balanced saline solution volume was observed with NeoSoniX (p<0.000001).
• Lower percentage of ultrasound energy was utilized with the NeoSoniX handpiece (p<0.000001).

Conclusions:

• The NeoSoniX handpiece demonstrates significant superiority over the conventional Legacy machine handpiece in cataract surgery.
• These benefits are consistent across all cataract hardness grades.
• NeoSoniX technology offers improved efficiency and reduced energy usage in phacoemulsification.
