The purpose of this study is to determine surgery effect on patients operated on visual quality, to suggest the use of the test FACT (Functional Acuity Contrast Test) as a routine test for these patients. It was a descriptive study with previous transversal measurements, a month and two months to the surgery. 32 eyes were evaluated in 17 patients, finding out differences in sensitivity to contrast between initial and a month later measurements, in the space frequency of 12.0 (p 0.00) y 18.0 (p 0.0104). the curve constructed with statiscal averages proved the improvement effect to sensitivity within high space frequencies. The results controvert the findings of sensitivity compromise to contrast, and indicate the need to apply FACT for a better evaluation of patients subjected to refractive surgery. |
