“…This study compared U/S time between the iChopper and control groups in each institution because U/S time was recorded differently by each phacoemulsification machine (effective phacoemulsification time [EPT], total U/S time, and EFX [U/S % and time used during phacoemulsification]). 20,21 This study conducted a chi-square test to compare laterality. A repeated-measures analysis of variance (ANOVA) was conducted to compare UDVA, CDVA, corneal ECD, hexagonality, CoV, central macular thickness, CCC size, and ACO and PCO scores during the follow-up periods between the 2 groups.…”

Purpose: To compare patient experiences and cooperation and the clinical outcomes illuminated chopper versus conventional chopper during cataract surgery. Setting: Four tertiary institutions in Korea Design: Prospective, randomized, paired-eye, controlled pilot study. Methods: This study enrolled 152 eyes of 76 patients who underwent bilateral cataract surgeries. The surgical method was randomly assigned to each patient's eye (one eye using the illuminated chopper with a light source and the other using the conventional chopper under the microscope light). Patient suffering scores (the degree of strong light perception, glare, inability to fixate, anxiety, discomfort, and fear) from 0 to 10 (10 being the most severe level); cooperation score from 0 to 3 (3 being the best cooperation); operating time; and corneal endothelial cell density (ECD) pre- and postoperatively were compared between the two groups. Results: The mean patient suffering score of all six parameters in the iChopper group was significantly smaller than those in the control group (all P<0.05). The mean patient cooperation score of the iChopper group (2.3 ± 0.8) was significantly greater than that of the control (1.6 ± 0.9; P<0.001). There was no significant difference in the mean operating time and corneal ECD at each visit between the groups, albeit the mean corneal ECD was significantly decreased from baseline to one month after cataract surgery in both groups. Conclusions: Phacoemulsification using the illuminated chopper provides less glare and anxiety and better cooperation during cataract surgery without increasing the operating time and damaging corneal endothelium compared to the conventional chopper.

“…The presumed possible reason is that the phacoemulsi cation technology on the capsule utilizes the relatively large operating space on the capsule, which makes it easier to fragment the nucleus, greatly shortens the ultrasonic time and ultrasonic energy, and also reduces the di culty of operation. Similarly, in the process of supracapsular phacoemulsi cation, the distance from the posterior capsule, the protection of the lens cortex, and the clear visual eld signi cantly reduce the incidence of posterior capsule rupture [13,14] .Although the phacoemulsi cation needle is closer to the corneal endothelium than the inside of the capsular bag during supracapsular ultrasound, the distance between the phacoemulsi cation needle and the corneal endothelial cells is still safe because the anterior chamber of high myopia is signi cantly deepened during perfusion.…”

Purpose：To compare and evaluate the differences in the therapeutic effects of different surgical methods for treating high myopia cataracts using supracapsular phacoemulsification technology and intracapsular phacoemulsification respectively, and to provide a basis for choosing the best surgical method. Methods: A total of 240 patients (268 eyes) with high myopia and cataract who underwent cataract surgery in our hospital from December 2020 to May 2022 were enrolled,of which 120 patients (136 eyes) were selected as the supracapsular phacoemulsification group, and 120 patients (132 eyes) as the intracapsular phacoemulsification group.The intraoperative average ultrasonic energy (AVE), effective phacoemulsification time (EPT), intraoperative complications, postoperative 1d, 1mo visual acuity and the corneal endothelial cell counts were recorded and compared. Results:Comparing the subgroups with the same nuclear hardness between the two groups, the AVE and EPT of the supracapsular group were lower than those of the intracapsular group, and the difference was significant(P＜0.05). Postoperative 1 mo UCVA and BCVA between two groups were significantly higher than those of postoperative 1d, and the difference was statistically significant (P<0.05). Posterior capsular rupture occurred in 0 eyes in the supracapsular group and6 eyes in the intracapsular group.There were no other serious surgical complications. Conclusion:The supracapsular method is simpler than the intracapsular phacoemulsification technique, uses less energy, takes less time, and has fewer complications.Therefore, Therefore, the results of this study support the use of supracapsular method for phacoemulsification cataract surgery in myopes.
