OUR EXPERIENCE WITH ACTIVE SENTRY AND CENTURION OZIL HANDPIECES

Area of Science:

• Ophthalmology
• Surgical Technology

Background:

• Phacoemulsification is a common cataract surgery technique.
• Intraocular pressure (IOP) fluctuations and post-occlusion surge are potential complications.

Purpose of the Study:

• To compare the performance of Active Sentry and Centurion Ozil phacoemulsification handpieces.
• To evaluate the impact on intraocular pressure, energy consumption, and fluid usage.

Main Methods:

• A comparative study involving 200 eyes (100 with Active Sentry, 100 with Centurion Ozil).
• Evaluation of intraoperative IOP, cumulative dissipated energy (CDE), ultrasound time, and balanced salt solution (BSS) consumption.
• All surgeries performed by a single surgeon.

Main Results:

• Active Sentry significantly reduced intraoperative IOP (46 mmHg) compared to Centurion Ozil (65 mmHg).
• Mean CDE and ultrasound time were significantly lower with Active Sentry.
• No significant difference in BSS consumption was observed.

Conclusions:

• Active Sentry handpiece effectively lowers IOP and eliminates post-occlusion surge during phacoemulsification.
• This leads to improved patient comfort and a more surgeon-friendly procedure, especially in complex cases.
