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

Figure 6

Penetrating keratoplasty and corneal patching for corneal perforation. (a–c) Penetrating keratoplasty with a cylindrical graft of 3.5 mm in diameter. (a) Half of the cornea is covered by a conjunctival flap, and the anterior chamber disappears, with UCVA being hand movement. (b–c) Eight months after surgery, corneal edema is alleviated greatly, the UCVA is 1.0 logMAR, and the curvature of the front cornea is 47.3/47.7. (d–f) Penetrating corneal patching with a conical graft. (d) Corneal perforation at the central cornea, with no anterior chamber, and the UCVA being 1.22 logMAR. (e–f) 12 months after surgery, the corneal patch is transparent, the UCVA is 0.40 logMAR, and the curvature of the front cornea is 38.7/44.5.
