13 Advantages of Tracey-VFA for screening refractive candidates
Accurate Refraction ~ 0.01 D (vs 0.25D) Manifest and Cycloplegia comparison Identification of high risk cases for night vision problems after conventional ablations (HOA and Total Aberrations) Integrated analysis with Corneal Topography (CTView V.5 software) R.Ambrósio Jr, M.D.
