Comparison of soft contact lens and rigid gas permeable lens fitting after laser in situ keratomileusis (LASIK)

Despite the accuracy of laser in situ keratomileusis (LASIK), a portion of patients will remain partially under-corrected or over-corrected following the surgery. For these patients, contact lenses maybe the best conservative option for visual rehabilitation and sustainability of minimum level of the binocular vision post operation. Due to the fact that cornea contour has been changed after Lasik surgery, fitting lenses on these corneas can be one of the most difficult challenges in the art of contact lens fitting. In general, patients with minor regular astigmatism may be fitted successfully with spherical or toric soft contact lenses. Patients with corneal irregularities should be fitted with rigid gas permeable lenses of traditional 3 or 4 curves or special designs such as keratoconus lens or reverse geometry lens.
