We report a case in which significant anisometropia and astigmatism after an autograft by rotation was treated by a 2-step laser in situ keratomileusis (LASIK) procedure. Six weeks after the lamellar keratotomy, photoablation was performed using the LADARVision 4000 excimer laser. The ablation depth was 87.2 mum on a 6.0 mm optical zone. One day postoperatively, the uncorrected visual acuity (UCVA) was 7/10 and the refractive error was -0.25 -0.25 x 67. Two months later, the UCVA was 5/10 and the best corrected visual acuity, 8/10 Parinaud 2 with a refractive error of +1.75 -1.25 x 16. The case demonstrates the effectiveness of 2-step LASIK for the correction of astigmatism induced by a corneal autograft. The significant reduction in autograft-induced astigmatism, together with stabilization of the higher-order aberrations, resulted in restoration of satisfactory functional vision.
