Abstract
BACKGROUND: This study was conducted to measure the distribution of white to white (WTW) corneal diameter and anterior chamber depth (ACD) in the study population by using optical biometry. METHODS: It was a cross-sectional observational study conducted at an Ophthalmology Out Patient Department of a Tertiary Care Centre. Optical biometry was performed in 650 eyes of the 325 patients using IOL Master and WTW and ACD were recorded. Differences in gender, and age-related alterations were analysed statistically. RESULTS: 195 (60%) subjects were males and 130 (40%) were females. Age of the study population ranged from 13 to 82 years and the mean age was 36.79 years. The mean WTW in the study population was 11.79 mm ± 0.05 mm and the mean ACD was 2.74 mm ± 0.03 mm. Mean WTW and ACD in male subjects was significantly greater than that of female subjects (p value < 0.001). No significant difference in WTW or ACD was seen between the various age groups. No correlation was seen between WTW and ACD in the study population. CONCLUSION: Mean WTW and ACD were smaller as compared to other population studies using intraocular lens (IOL) Master. This distribution has paved the way for a population based nomogram for our country which will help us plan surgeries in a better way.
