Study Summary
This study will evaluate the utility of TrueTear™ to improve anterior corneal surface imaging quality before cataract surgery, refractive lens exchange, or laser refractive surgery.
Primary Outcome
Surface asymmetry index (SAI) is an index that indicates an average value of the corneal power differences between the points spatially located at 180° from 128 equidistant meridians. A radially symmetrical surface has a value of zero, and this value increases as the degree of asymmetry is greater. Higher values are worse, but there is no set maximum value and no unit of measure.
