Preoperative corneal anterior surface wavefront error, RMS map (over a 6 mm diameter optical zone), right eye (A) and left eye (B). The RMS value was 2.1 in both eyes. After 24 months from the Descemet stripping automated endothelial keratoplasty, right eye (C) and left eye (D); the RMS value was, respectively, 1.7 in and 1.4.. Note: The patterns showed a slight improvement in corneal profile with a mild reduction of higher-order aberrations.. Abbreviation: RMS, root mean square.

The RMS was 2.1 in the right and in the left eye (Figure 1A, B). The RMS was 1.7 in the right eye and 1.4 in the left eye (Figure 1C, D).
Biomicroscopic image of the patient's eye after 24 months from Descemet stripping automated endothelial keratoplasty surgery (A, right eye; B, left eye). Both corneas are clear assessing the success of the transplant. Anterior segment optical coherence tomography images of right eye (C) and left eye (D) evidenced the different corneal thickness between the two eyes, 24 months post surgery.

The grafts resulted of uniform thickness with no clinically significant interface haze (Figure 2A, B). CDVA was 20/25 in both eyes (right eye -0.50=-1.25x170 ; left eye -0.50=-1.00x10 ). Corneal thickness detected with AS-OCT was 633 microm, with a lenticule thickness of 206 and 439 microm, with a lenticule thickness of 48 microm, respectively, in the right and in the left eye (Figure 2C, D).
