Characteristics of biological parameters and implantable collamer lens (ICL) size selection in moderate, high, and super-high myopia eyes.

Objective: To analyze the characteristics of anterior segment biometric parameters in moderate, high, and super-high myopia eyes for ICL size selection.

Methods: A total of 246 eyes of 131 patients were included in this prospective observational cohort study. Preoperative axis length (AL), central keratometry (Kc), central corneal thickness (CCT), white-to-white (WTW), internal anterior chamber depth (ACD), trabecular iris angle (TIA), anterior chamber width (ACW), angle-to-angle distance (ATA), crystalline lens rise (CLR), lens thickness (LT), sulcus-to-sulcus (STS), ICL size, and postoperative vault at 1 month were recorded and compared among the different degrees of myopia groups.
