In summary, we found significant differences in the lens position and relative lens position among various ethnic groups, with Whites having the greatest LP and RLP. In addition, Hispanics followed by Asians had the smallest LP and RLP. These findings may have relevance as to the relative risk for ACG in these groups and potentially in the IOP outcome after cataract surgery. Our results can serve as a starting point for designing future prospective observational studies which have larger populations and a variety of ethnicities.
