摘要

The article presents a case report of patient B., 28 years old, with the diagnosis of simple myopic astigmatism, refractive amblyopia of the right eye and compound myopic astigmatism of the left eye. Taking into consideration a combination of astigmatism and thin cornea the surgeries were performed in the right eye: the first stage a?? femtosecond astigmatic keratotomy (Femto-AK), the second stage six months later a?? photorefractive keratectomy (PRK). After the Femto-AK there occurred a planned reduction in the cylindrical refractive component by 4.5D and a predicted increase in the spherical refractive component by 1.5D (6 months after the Femto-AK a?? after a stabilization of the refractive effect). Changes of corneal thickness in the postoperative period were not observed. The corneal topography showed a significant decrease of the surface irregularities. After the stabilization of the refractive effect, the second stage was carried out (6 months after the Femto-AK) in order to re-correct a residual refractive spherical component by the custom PRK. As a result of the performed operations the uncorrected visual acuity (UCVA) corresponding to the best corrected visual acuity (BCVA) in the preoperative period was achieved. This case confirms the safety and efficiency of the two-stage surgical treatment of corneal astigmatism for patients with a thin cornea. ?? ??
