A Comparison of Intraoperative Metrics between the Infiniti with and the Centurion without Intelligent Phacoemulsification Systems
摘要： Purpose: To compare the efficiency and safety of two phacoemulsification systems, the Infiniti with intelligent phacoemulsification (IP) and the Centurion without IP, in terms of intraoperative metrics of phacoemulsification and the occurrences of adverse events and intraoperative tip obstruction. Design: Comparative case series. Methods: A consecutive series of 340 eyes (151 eyes with the Infiniti, 189 eyes with the Centurion) was evaluated. A 2.4 mm sclerocorneal incision was used with the Infiniti, and a 2.0 mm incision was used with the Centurion. Phacoemulsification of the nucleus was performed using the phaco chop technique, with the IP function of the Infiniti turned on and the IP mode of the Centurion turned off. From among the parameters displayed on the panels of both devices, ultrasound (US) time, cumulative dissipated energy (CDE), aspiration time, and estimated balanced salt solution (BSS) aspiration volume were investigated and compared between the devices. Results: A comparison of all subjects found significant differences between the two devices in mean CDE (p=0.02) and mean aspiration time (p=0.003), but not in mean US time (p=0.43) or mean estimated BSS aspiration volume (p=0.07). For grade 3 nuclei, all parameters of mean US time (p=0.0044), mean CDE (p ≤ 0.001), mean aspiration time (p<0.001), and mean estimated BSS aspiration volume (p=0.001) showed significant differences favoring the Centurion. Conclusions: Compared to the Infiniti with IP mode, cataract surgery with the Centurion without IP mode is likely to be performed with less phacoemulsification energy and higher efficiency.

Effectiveness of intraoperative intraocular lens use on improving surgical safety for dense cataract phacoemulsification: a randomized controlled trial
摘要： We designed this study to assess if surgical safety can be improved by intraoperative use of intraocular lens (IOL) for cataract phacoemulsification. We performed phacoemulsification cataract removal on 401 patients. We randomly assigned these patients into three groups: the standard setting (Group I, n = 134), with reduced vacuum and flow rate (Group II, n = 137), and with IOL insertion before the last quadrant was emulsified with standard setting (Group III, n = 130). The primary outcomes included the risk of posterior capsular rupture (PCR), ultrasound time, energy, and complications. The secondary outcomes included central corneal thickness (CCT), CCT changes, endothelial cells (ETC) counting, ETC loss, and the best corrected distance visual acuity (BCVA) measured on day 1, day 7 and day 30. If PCR occurred, we emulsified the residual lens materials after insertion of IOL and clean of the prolapsed vitreous. We found that the risk of PCR in Group III (0/130) was lower than Group I (9/134, corrected relative risk (RR) = 18.44, 95% CI: 1.08–313.56) and Group II (3/137, corrected RR = 6.64, 95% CI: 0.35–27.41). Group III showed better BCVA on day 1 and 7, less ECC loss on day 7 and 30, and less CCT increase on day 1 and 7. No cases converted to extracapsular cataract extraction. No residual lens materials misdirected into vitreous cavity. Intraoperative use of IOL can improve surgical safety for dense cataract phacoemulsification.
