Abstract :
Purpose: To evaluate the biometric indices and keratometry values in 250 subjects with. Methods: An observational study where keratometry and biometric indices of 250 subjects with cataract were taken. These included axial length (AL), anterior chamber depth (ACD) and keratometry readings (K). The mean value and range for each parameter was assessed. In addition, the measurements for AL and ACD were evaluated in relation to age and sex of the participants. Results: Our study included 250 eyes of 250 patients who presented with cataract. Out of these, 148 were women (59.2%) and 102 were men (40.8%). Also, females presented for cataract surgery at a slightly older age than males (P=0.5). The mean AL and ACD were 22.76±2.08 and 2.49±0.75 mm respectively. The mean corneal astigmatism was 1.0 ± 0.50D, with 91 (36.4%) eyes showing astigmatism ≥ 1 D. Men had significantly longer AL, higher ACD in comparison to women (P < 0.001). With advancing age, the mean AL (r = 0.12; P<0.001) and the mean ACD (r = 0.23; P<0.001) were found to decrease. Conclusion; Our study provides the normative biometric indices and their relationship with age and gender in Indian subjects with cataract. We encourage ophthalmologists to personalize the formulas’ keeping in consideration the variations in biometric and keratometric indices encountered in the Indian population.
