Topography Guided LASIK by Different Protocols for Treatment of Astigmatism

using the data obtained from the topolyzer for correction of refractive errors specially astigmatism we use 3 different treatment protocols

using for ablation the exact manifest refraction

full topography modified refraction means changing both sphere and cylinder power in the ablation profile

partial topography modified refraction means changing only cylinder power and axis in the ablation profile
