Abstract：
PURPOSE:To characterize crystalline lens dimensions derived from in-vivo spectral-domain optical coherence tomography (SD-OCT) and identify associations between these parameters, ocular biometry and age. METHODS:In this retrospective study, lens thickness (LT), lens diameter (LD) and lens volume (LV) were measured intraoperatively with SD-OCT in 293 eyes undergoing lens surgery. Correlations among LT, LD, LV, age, axial length (AL) and anterior chamber depth (ACD) were analyzed. Multiple regression analysis was performed to determine whether a combination of biometric data could predict LD and LV. RESULTS:Wide variation was observed in LT (3.6 to 5.7mm), LD (7.5 to 11.9mm) and LV (119.9 to 312.4 mm3) of aging eyes. Correlations among the 3 lens dimensions were statistically significant (LV-LT: r=0.785; P<.001; LV-LD: r=0.696; P<.001; LT-LD: r=0.121; P=.039). With age, the correlation coefficients of LT, LD and LV were 0.526, 0.326 and 0.573 respectively (P<.001). While there was significant correlation of AL with LT (r=-0.137; P=.002) and LD (r=0.268; P<.001), it was not significant with LV (r=0.084; P=.15). Subgroup analysis revealed that 19.8% of the long eyes had LD >1 standard deviation (SD) above and 5.2% had LD <1 SD below the mean LD. CONCLUSION:The dimensions of the aging lens vary considerably, and are most accurately characterized by direct measurement of LT, LD, and LV rather than assumptions based on AL. These findings challenge historically proposed relationships between LD and AL, and represent a normative dataset of contemporary geometric features of the aging lens, possibly aiding in surgical decision making and future developments in lens surgery.
