Purpose: To refine and develop systems for classifying the topography of myopic comeas
using axial, instantaneous, refractive, and profile difference maps.
Setting: Baylor College of Medicine, Cullen Eye Institute Houston, Texas, USA.
Methods: Using the EyeSys Corneal Analysis System'TM, computerized videokeratographs
of 153 corneas of 78 myopic patients were retrospectively analyzed. Patterns
were defined with respect to the mid-diopttic green color. Relationships among pattern
types, refractive power, corneal power, corneal uniformity index (CU index), and predicted
corneal visual acuity (PC acuity) were calculated. |
