Aim: To compare parameters of phacoemulsification using handpiece Active Sentry and Centurion Ozil.
Methods: We have evaluated results of 200 eyes of 129 patients that were operated for cataract at the Department of Ophthalmology. All surgeries were performed by one surgeon (NJ). In 100 eyes handpiece Active Sentry was used and in 100 eyes handpiece Centurion Ozil was used. The intraocular pressure during surgery (IOP), cumulative dissipated energy (CDE), ultrasound time (U/S time) and estimated consumption of balanced salt solution (BSS) were evaluated.
Results: Using handpiece Ozil Centurion the IOP was 65 mmHg, use handpiece Active Sentry enabled decrease safely peroperative IOP to 46 mm Hg withouth increase of fluctuation or declension of stability of the anterior chamber. The mean CDE a U/S time were significantly statistically decreased using Active Sentry versus Centurion Ozil handpieces. Difference in estimated consumption of balanced salt solution was not statistically significant.
Conclusion: Our results proved that using handpiece Active Sentry enabled statistically significantly decrease IOP during phacoemulsification and eliminated post-occlusion surge. This brings several advantages: more painless surgery for patients and more user-friendly procedure for surgeon especially in challenging cases (intraoperative floppy iris syndrome or severe myopia).
