Evaluation on the clinical effects of the soft-shell technique with domestic materials during the cataract phacoemulsification / 中国医师进修杂志

ABSTRACT

Objective To evaluate the efficacy of the soft-shell technique with domestic materials during the cataract phacoemulsification. Methods Eighty-two eyes of 76 patients with the mature cataract phacoemulsification were divided into 3 groups randomly, including 28 eyes using the soft-shell technique with sodium tvlose and sodium hyaluronate (the domestic group),and 28 eyes using DuoVisc (Viscoat+ProVisc) (the import group), and 26 eyes using sodium hyaluronate (the common group). Results The average naked vision was 0.50 ± 0.22,0.51 ± 0.27,0.27 ± 0.21 respectively on the first day after operation.There was no signiticant difference between the domestic group and the import group (P＞0.05 ), while the first two groups and the common group had significant difference (P ＜ 0.05). The average naked vision was 0.61 ± 0.17,0.63 ± 0.18,0.58 ± 0.18 respectively 7 days after operation. There was no statistical difference among the three groups (P ＞ 0.05 ). The rate of corneal endothelial cells 1 month after operation was 7.1% in the domestic group,7.0% in the import group and 15.9% in the common group. It was clear that the rate in the domestic group and the import group was much lower than that in the common group. Meanwhile, the difference existed statistically between the two groups and the common group (P ＜ 0.01 ). However, the difference between the domestic group and the import group had no statistical significance. Conclusion The soft-shell technique with domestic materials is as safe and effective as that with the import materials in protecting the corneal endothelial cells during the cataract surgery in patients with the mature cataract.
