Clinical Experience with the Tracey VFA in Brazil Renato Ambrósio Jr. Universidade de São Paulo Oftalmologia Instituto Benjamin Constant Rio de Janeiro
Why should I buy a wavefront analyzer?
Goals of the Preop exam in refractive surgery Screening refractive candidates n Patient education n Surgical Planning n R. Ambrósio Jr, M. D.
Screening refractive candidates Complete eye exam n Complementary exams n Interview with the patient n R. Ambrósio Jr, M. D.
Preop exam in refractive surgery Which exams should we do? R. Ambrósio Jr, M. D.
UW Refractive Clinic Study n 0. 9% of the candidates had keratoconus or pellucid marginal degeneration R. Ambrósio Jr, M. D.

CT View – Scales for Corneal Topography R. Ambrósio Jr, M. D.
KERATOMETRY CORNEAL TOPOGRAPHY REFRACTION WAVEFRONT R. Ambrósio Jr, M. D.
Advantages of Tracey-VFA for screening refractive candidates Accurate Refraction ~ 0. 01 D (vs 0. 25 D) n Manifest and Cycloplegia comparison n Identification of high risk cases for night vision problems after conventional ablations (HOA and Total Aberrations) n Integrated analysis with Corneal Topography (CTView V. 5 software) n R. Ambrósio Jr, M. D.
Screening refractive candidates with the Tracey VFA – Bad candidate (BSCVA 20/15 -2)
PSF Simulation for Patient education Bad candidate (BSCVA 20/15 -2) All Aberrations Only HOA
Screening refractive candidates with the Tracey VFA Instituto de Olhos Renato Ambrósio Rio de Janeiro
PSF Simulation for Patient education All Aberrations Only HOA
Qualidade da Visão R. Ambrósio Jr, M. D.
Integrated Analysis with the CT View WF – Topo = Intraocular Optics
Clinical Applications: Monocular Diplopia – Poor CL Fit after PKP
