Effect of ICL-V4c Implantation in Treatment of Ultra-High Myopia

Objective: To observe the safety and effectiveness of ICL-V4c implantation in the treatment of ultra-high myopia over -10 D, and to explore the relationship and rules between the improvement of vision (△LogMAR) and preoperative spherical diopter (SD). Methods: This was a retrospective study. Eight hundred and two patients (1 380 eyes) with ultra-high myopia were treated by ICL-V4c implantation in Beijing Tongren Hospital from December 2016 to January 2020. The preoperative SD was -23.50 D≤SD≤-6.00 D (mean -11.54±3.59 D). The patients were divided into group A (-10 D1. There was a significant correlation between △LogMAR and group (P<0.001). △LogMAR in the B3 and B4 groups was significantly higher than that in A, B1 and B2 groups (adjusted, P<0.001). The intraocular pressure (IOP) in group B was higher than that in group A (P<0.001), and the proportion of postoperative high IOP was higher (P=0.008). Conclusions: ICL implantation is safe and effective for patients with ultra-high myopia over -10 D, but the long-term effect needs further explorations. The improvement of BCVA in patients with -22 D≤SD≤-16 D was higher than that of patients with -16 D
