To compare parameters of phacoemulsification using handpiece Active Sentry and Centurion Ozil.
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.
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.
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).
比较使用 Active Sentry 和 Centurion Ozil 手柄的超声乳化参数。
我们评估了在眼科部门接受白内障手术的 129 名患者的 200 只眼的结果。所有手术均由一名外科医生（NJ）进行。在 100 只眼中使用了 Active Sentry 手柄，在 100 只眼中使用了 Centurion Ozil 手柄。评估了手术期间的眼内压（IOP）、累积耗散能量（CDE）、超声时间（U/S 时间）和平衡盐溶液（BSS）的估计消耗量。
使用 Centurion Ozil 手柄时，IOP 为 65mmHg，使用 Active Sentry 手柄可将术中 IOP 安全降低至 46mmHg，而不会增加波动或前房稳定性下降。与 Centurion Ozil 手柄相比，使用 Active Sentry 手柄时 CDE 和 U/S 时间的平均值显着降低。平衡盐溶液估计消耗量的差异无统计学意义。
我们的结果证明，在超声乳化过程中使用 Active Sentry 手柄可显着降低 IOP，并消除后阻塞浪涌。这带来了几个优势：为患者提供更无痛的手术，为外科医生提供更用户友好的程序，特别是在具有挑战性的情况下（术中虹膜松软综合征或严重近视）。
