Ocular biometric differences between long and not long-axial length eyes

This is the authors' abstract. We don't add key points for this paper.

This retrospective cross-sectional study aimed to measure parameters of preoperative cataract patients and examines the correlations between each parameter. The 210 subjects had their ocular axial lengths measured with OA-2000. The endpoints were ocular axial length (AL), central corneal thickness (CCT), average corneal radii (CR), white-to-white(WTW), anterior chamber depth(ACD), and lens thickness(LT). AL was mainly employed for each person. Each parameter was analyzed for correlations in a round-robin manner. Regression analyses were performed on parameters correlated with AL. The parameters correlated with AL were CR (r = 0.33, p < 0.0001), WTW (r = 0.29, p < 0.0001), ACD (r = 0.59, p < 0.0001), and LT (r = −0.30, p < 0.0001). These parameters affected AL in all single regression equations (CR (P < 0.0001), WTW (P = 0.0002), ACD (P < 0.0001), LT (P = 0.0001)). In multiple regression analyses, CR, ACD, and LT might affect AL (CR (P = 0.0002), ACD (P < 0.0001), LT (P = 0.018)). LT tended to be thinner as AL increased, while CR, WTW, and ACD tended to increase. This information will be useful in developing strategies for ophthalmic surgery.
