I have short-sightedness and astigmatism with -1.50 D sphere and -3,50 D cylinder, axis 150 in the right eye, -4.50 D sphere and -3.75 D cylinder, axis 10 in the left eye. Do I have a chance for vision improvement?

Yes, you do. Your refractive error is possible to be corrected provided the preliminary qualifying examination confirms your eligibility for laser vision correction. During the examination a number of tests are conducted to verify your eligibility for the procedure and choose the most suitable surgical method.
