Corneal refractive surgery can cause, at least in some subjects, significant degradation or retinal image quality as a result of increased aberrations and / or scattered light. Measurement of retinal image degradation is not easy to carry out and its effect on visual performance is difficult to quantify. A new test based on contrast acuity assessment (CAA) has been developed. The test is simple, easy to use and identifies those subjects that fall outside the "normal range".
