The procedure resulted in complete resolution of corneal oedema within the first postoperative month (Fig 1a). In the first postoperative month, anterior corneal fibrosis resolved (Fig 1b) and the patient's corrected distance visual acuity reached 20/32, with a manifest refraction of -1.50 sph -2.00 cyl x 120 .

Anterior segment optical coherence tomography (AS-OCT) was performed in order to establish the extension of fibrosis in the anterior stroma; in fact, the depth of the scar was estimated at 112 mum from the corneal surface centrally and at 120 mum in the mid-periphery (Fig 2a). A variety of other parameters were also calculated with the use of AS-OCT; central corneal thickness (involving both the scar and the graft) was measured 665 mum and graft thickness was measured 117 mum at its thinnest point (Fig 2a), Thus, the residual corneal tissue of the recipient was estimated at 548 mum. Postoperative AS-OCT was performed depicting the resolution of the scar (Fig 2b).
