Individualized Corneal Patching for Treatment of Corneal Trauma Combined with Tissue Defects

Figure 4

Penetrating corneal patching with an irregular wedge-shaped patch for pencil pricking. (a) The sutured cornea is packed with the amniotic membrane in the wound, with secretions accumulating on the central cornea, and the UCVA is 1.0 log MAR. (b) Morphology of tissue defects after removing the sutures and amniotic membrane. (c) A photograph at 1 week after surgery. (d–f) Examination at 4 years after surgery. (d) The graft opacity is decreased, and the UCVA is 0.1 logMAR. (e) AS-OCT shows that the longitudinal of the anterior surface of the patch is 1.93 mm, while the width of the posterior surface is 144 μm. (f) The curvature of the front cornea is 40.0/41.0.
