(A) Visual acuity HM of the right eye, central corneal ulcer about 6 mm, feathery edge, moss formation. (B) 2 days after surgery, visual acuity HM, implant edema, no interlaminar effusion, bubble injection during anterior chamber partially absorbed. Tacrolimus eye fluid, bromfenac sodium eye fluid, sodium hyaluronate eye fluid, itraconazole 0.2 g, once a day, for 3 weeks. (C, D) 10 days after surgery, visual acuity was counting fingers (CF), edema was relieved, the epithelium was repaired, and there was no interlaminar effusion. The treatment was continued as before. (E) One month after surgery, visual acuity was 3.7, transparency was good, and no loosening of sutures was observed. 5:30 o’clock location of the limbus cornea Limbal neovascularization invades intercorneal layer. Stop bromfenac sodium eye fluid, add loteprednol eye fluid. (F) 3 months after surgery, visual acuity was 4.0 and corrected visual acuity was 4.4. The central area of the implant was transparent and some sutures were removed. The pupil is 3 mm in diameter and slightly insensitive to light reflex. Remove all sutures and continue anti-rejection therapy. (G) 18 months after surgery, visual acuity was 4.5 and corrected visual acuity was
4.7. The pupil area implant has good transparency. 5:30 o’clock location of the limbus cornea, the neovascularization became thinner and some atrophy. Continue tacrolimus eye fluid, 2 times per day.
Figure 3 Case 3: The patient is a 67-year-old male, with the left eye eyesight decline in 2 d, pseudomonas aeruginosa ulcer, biological engineering corneal andante layer corneal transplantation, postoperative systemic intravenous drip 3 days amikacin therapy, local tobramycin eye drops 1 time per hour, tacrolimus eyedrops eye 4 times per day, bromfenac sodium eye drops eye for 2 times per day, the sodium hyaluronate drops eye 4 times per day
(A) Preoperative vision HM, the conjunctiva of the left eye was highly hyperemic and edema, the gray and white ulcerated surface of the central cornea was about 6 mm in diameter, the matrix was dissolved and thin, and purulent secretions were attached. (B) 3 days after the operation, the visual acuity was CF, the implant was gray and white with edema, and no interlayer effffusion was observed. Continue treatment as before. (C, D) 14 days after surgery, visual acuity was 4.1, the graft was transparent, and the epithelium was well repaired. The sutures did not come loose. Antibiotics were stopped and anti-rejection therapy continued. (E) 1 month after surgery, visual acuity was 4.2, corrected visual acuity was 4.5, and no loosening of sutures was observed. Continue anti-rejection therapy. (F) 3 months after surgery, visual acuity was 4.2, corrected visual acuity was 4.5, and no loosening of sutures was observed. The sutures were removed and anti-rejection therapy continued. (G) 14 months after surgery, visual acuity was 4.4 and corrected visual acuity was 4.6. The phytophilic margin is pale and slightly cloudy. Tacrolimus eye drops were recommended for 2 times per day and outpatient follow-up.

Figure 4 Case 4: A 39-year-old female patient with right eye viral keratitis underwent bioengineered lamellar keratoplasty
(A) Preoperative visual acuity was CF, and the diameter of the corneal pupil area was about 3.5 mm. (B) 2 days after the operation, the visual acuity was HM, the implant was gray and white with edema, and no interlayer effffusion was observed. Tacrolimus eye infusion 4 times per day, prednisolone eye infusion 2 times per day, sodium hyaluronate eye infusion 4 times per day. (C, D) 10 days after surgery, the visual acuity was CF, the graft edema was reduced, and most of the epithelium was not repaired. The sutures did not come loose. Calf serum eye gel was applied 4 times per day. (E, F) 1 month after surgery, visual acuity HM, extensive loss of graft epithelium, partial dissolution and thinning of matrix. Remove loose sutures and resuture. The treatment is the same. (G) 2 months after surgery, the visual acuity was CF, no loosening of the suture was observed, the graft epithelium was repaired, the matrix was partially dissolved and thinned, and gray pall was formed. Bioengineered corneal grafts were removed and allogeneic human grafts replaced. Continue anti-rejection therapy. (H) One month after the second operation, visual acuity was 4.2 and corrected visual acuity was 4.4. Continue anti-rejection therapy. (I) 3 months after the second operation, visual acuity was 4.5 and corrected visual acuity was 4.8. The graft was transparent and some sutures were removed.
