Purpose: To compare the clinical outcomes following phacoemulsification in Ellips (Signatureⓡ) and Ozil (Infinitiⓡ) modes.
Methods: Phacoemulsification was performed using Ellips and Ozil modes in 30 eyes each.The phacoemulsification parameters such as the maximum phaco power, vacuum power, and aspiration rates were consistent between the two modes. Nuclear sclerosis grade, average phaco power, and the total phaco energy were recorded. The best-corrected visual acuity, central corneal thickness, and endothelial cell counts were measured preoperatively and on postoperative day 1 and on week 1, 2, 4, and 8.
Results: The average phaco power and total phaco energy were significantly lower in patients with nuclear sclerosis grades 1 and 2 in the Ellips group compared with those in the Ozil group (p < 0.05). However, when these parameters were measured in patients with nuclear sclerosis grades 3 and 4, the difference was not significant between the 2 groups (p > 0.05). Two months postoperatively, the changes in central corneal thickness were 8.73 ± 17.62 and 5.19 ± 14.42 μm in the Ellips and Ozil groups, and the changes in endothelial cell count were 100.4 ± 196.5 and 145.7 ± 323.8 cells/mm2 (p > 0.05), respectively. The differences did not reach statistical significance.
Conclusions: Although the ultrasound energy used in the surgical procedure was significantly lower in the Ellips group compared with that in the Ozil group, especially in patients with nuclear sclerosis grades 1 and 2, there were no significant differences in the best-corrected visual acuity, central corneal thickness, and endothelial cell count between the 2 groups.
