Study of distribution of white-to-white corneal diameter and anterior chamber depth in study population obtained with optical biometry using intraocular lens (IOL) master

Abstract

BackgroundThis 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. MethodsIt 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. Results195 (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 11.79mm±0.05mm and the mean ACD was 2.74mm±0.03mm. 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. ConclusionMean 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.
