Abstract:
PURPOSE: To evaluate the parameters affecting vaulting and correlation between preoperative crystalline lens rise and vaulting after implantable collamer lense (ICL) implantation. METHODS: A total of 53 eyes of 34 patients who underwent ICL implantation were examined retrospectively. White-to-white (WTW) and anterior chamber depth (ACD) were obtained from scanning topography (ORB scan) before surgery. Preoperative crystalline lens rise (CLR) and vaulting at 6 months after ICL implantation were measured using anterior segment optic coherence tomography (AS-OCT). Multiple regression analysis was performed to evaluate the factors affecting central vaulting. RESULTS: The mean preoperative crystalline lens rise was -120 +/- 219 microm, and mean central vaulting 6 months after surgery was 544 +/- 175 microm. Preoperative SE, WTW, ACD, and CLR were significantly correlated with vaulting at 6 months after surgery. With the use of meaningful variables, multiple regression analysis showed that CLR, WTW, ACD and SE, in that order of influence, had significant effects on vaulting and the multiple regression equation was obtained as follows: Vaulting (microm) = (160.913 x ACD (mm)) + (170.134 x WTW (mm)) + (-0.338 x CLR (microm)) + (-23.783 x SE (D)) - 2250.184. CONCLUSIONS: CLR had a stronger influence on vaulting after ICL implantation than the previously proven parameters: WTW, ACD, and SE. In addition to WTW, ACD and SE, CLR should also be considered a new criterion for estimating vaulting after ICL implantation.
