Purpose
To compare the efficacy of the Centrion handpiece anti-surge system (Active Sentry®) and main body, and evaluate the frequency of the anti-surge system in the Centrion handpiece in cataract surgery according to the grade of nucleosclerosis.
Setting
600 eyes of 418 patients who underwent cataract surgery by the same surgeon using the same technique were selected for the retrospective study.
Methods
Intraoperative parameters included ultrasound time (UST), mean cumulative dissipated ultrasound energy (CDE), and balanced salt solution (BSS) use. Clinical measurements were made preoperatively, and at one day, one month and two months postoperatively, including the best corrected visual acuity (BCVA), the central corneal thickness (CCT), and the endothelial cell count (ECC) in anti-surge group(handpiece, N=300) and control group(main body, N=300). Within the anti-surge group, number of anti-surge system activated were collected. Data were analyzed using Mann-Whitney test.
Results
No significant differences in BCVA and ECC were shown between the two groups in all nucleosclerosis grades. UST of the anti-surge group was lower in nucleosclerosis grade 3(N3), but higher in N4 than that of the control group(P<0.001). In all cataract grades except N6, more BSS was used in the control group than in the anti-surge group(P<0.001, 0.002, 0.018 each). In the anti-surge group, anti-surge activation frequency, UST, and BSS amount increased significantly with increasing nucleosclerosis grades(P<0.001). In cataracts with zonulysis and poor mydriasis, the anti-surge system was activated more, and more UST and BSS were used compared to the cataracts in the normal situation(P = 0.003, 0.011, <0.001 and 0.001, 0.001, <0.001 each).
Conclusions
Because of the fast-reacting anti-surge, more UST was used to emulsify hard nuclei in the handpiece anti-surge system than in the body. UST The anti-surge system in the Centrion handpiece is active more frequently with increasing nucleosclerosis grades and in cataract surgery with zonule weakness and poor mydriasis. Therefore, the anti-surge system in the Centrion handpiece helps the surgeon perform safer cataract surgery in higher nucleosclerosis grade, zonule weakness, or poor mydriasis.
