Tectonic Keratoplasty to Restore the Bulbar Wall after Block Excision of Benign and Malignant Intraocular Tumors

Figure 4

Patient 3 before and after surgery. (a) Large epithelial cysts of the iris involving the upper nasal quadrant of the right eye. Cysts stretch the pupil foramen and cause circumscribed corneal failure. (b) Block excision of the cysts, iris, cornea, and limbal sclera after Hanna trephination. (c) Eccentric corneal graft is clear one-year postoperatively, and sutures are still in situ; a large iris coloboma is observable. (d) Two months after penetrating keratoplasty and cataract surgery. Photo shows that the graft is clear and the cosmetic IOL is well positioned in the sulcus; double continuous Nylon 10.0 suture is in situ.
