To compare the intra-operative surgical performance of Quatera 700 with Centurion and Signature Pro phacoemulsification systems.
Nethradhama Superspeciality Eye Hospital, Bangalore, India.
Prospective, interventional, 3-arm, randomized comparison study.
A total of 180 non-consecutive eyes satisfying the eligibility criteria were recruited. N = 60 eyes were operated using each of the above systems, of which n = 30 eyes had LOCS III grade 1-2, and n = 30 eyes had grade 3-4 nuclear density. Phacoemulsification with foldable IOL implantation was performed by a single experienced surgeon. Chamber stability scores (1-4, 4 being the worst), fluid turnover per case, surge incidence and intra-operative complications were assessed.
Intra-operatively, the mean chamber stability score was significantly better for the Quatera 700 in both the soft and dense cataract groups compared to the other two machines (p < 0.001). Total Phaco Time (TPT) with Quatera 700 was significantly lower compared to Signature Pro, while it was comparable with Centurion for both the soft and dense cataract groups. The mean fluid turnover was significantly lower for the Quatera 700 in the dense cataract group (p = 0.04) and so was the combined phaco and I/A time (p = 0.01) when compared with Signature Pro. One eye operated with Signature Pro and 2 eyes operated with Centurion had PCR due to surge. The mean corneal clarity scores on POD-1 and specular counts at 2 weeks and 6 months were comparable.
The new Quatera 700 system resulted in lesser TPT, fluid turnover and phaco + I/A time than Signature Pro, while its performance was comparable to Centurion for these parameters. Moreover, the surgeon graded intra-operative chamber stability scoring was highest, when compared to the other two systems.

比较Quatera 700与Centurion及Signature Pro超声乳化系统的术中手术表现。
印度班加罗尔的Nethradhama超级专科医院。
前瞻性、干预性、三臂随机对照研究。
共招募了180只符合入选标准的非连续眼睛。使用上述每种系统对N = 60只眼睛进行手术，其中n = 30只眼睛的晶状体混浊分级系统（LOCS）III为1 - 2级，n = 30只眼睛的核密度为3 - 4级。由一位经验丰富的外科医生进行超声乳化联合折叠式人工晶状体植入手术。评估前房稳定性评分（1 - 4分，4分为最差）、每例的液体周转率、浪涌发生率及术中并发症。
术中，在软性和致密性白内障组中，与其他两台机器相比，Quatera 700的平均前房稳定性评分均显著更好（p < 0.001）。Quatera 700的总超声乳化时间（TPT）显著低于Signature Pro，而在软性和致密性白内障组中，其与Centurion相当。与Signature Pro相比，Quatera 700在致密性白内障组中的平均液体周转率显著更低（p = 0.04），超声乳化和灌吸时间总和也更低（p = 0.01）。使用Signature Pro手术治疗的1只眼睛和使用Centurion手术治疗的2只眼睛因浪涌发生后囊破裂。术后第1天的平均角膜清晰度评分以及术后2周和6个月的内皮细胞计数相当。
新型Quatera 700系统的TPT、液体周转率和超声乳化 + 灌吸时间均低于Signature Pro，而在这些参数方面其表现与Centurion相当。此外，与其他两个系统相比，外科医生对术中前房稳定性的评分最高。
