Cataract blindness presents an enormous problem in terms of public health burden, economic loss and social burden. A hospital based retrospective study reviewed the medical data of 520 patients (mean age 68.42±11.77 years) to detect gender based comparison of axial length, corneal curvature and power of intraocular lens that was implanted in patients undergoing cataract surgery in Western Nepal. A significant inter-gender differences was seen in age, axial length, keratometric values and intraocular lens power between the two groups (p<0.05). Females had shorter axial length (22.85±0.86 mm) and steeper corneal curvature (K1: 43.79±1.51 D, K2: 44.46±1.54 D) compared to males (23.04±1.01 mm, K1: 43.51±1.40 D, K2: 44.16±1.40 D). The axial length had a decreasing trend with increasing age in both the sexes. The average power of the intraocular lens was 21.28±1.91 D. In conclusion, the axial length of Nepalese population was comparable to Indian and Pakistani population. However, it was slightly shorter than Whites, Middle-Eastern and some Asian population. The keratometric value ranges from 38.75-50.00 D. Maximum number of patients required intraocular lens of power between 20.00-22.99 D
