The long-term surgical outcomes of conjunctival-limbal autograft procedure with or without penetrating keratoplasty in eyes with unilateral limbal stem cell deficiency: Muhammet Derda Ozer, Emre Altinkurt, Nilufer Alparslan
Taiwan Journal of Ophthalmology 2020 10(1):22-28
AIM: The aim of the study is to report the results of conjunctival-limbal autograft (CLAU) transplantation and penetrating keratoplasty (PK) in eyes with limbal stem cell deficiency (LSCD) due to chemical or thermal injury.
METHODS: Thirty-one eyes of the 31 patients, who had unilateral LSCD due to chemical or thermal injury, were included in the study. Bilaterally affected cases and LSCD due to Steven-Johnson syndrome and mucous membrane pemphigoid were excluded from the study. All patients underwent a complete ophthalmologic examination. The surgical procedures, postoperative complications, ocular surface status, and visual outcomes were noted.
RESULTS: In the CLAU group, regular corneal epithelium and ambulatory vision (≤1.0 logarithm of the minimum angle of resolution [20/200]) were achieved in 81% of eyes, including 22 eyes (71%) that were assessed after a mean follow-up period of 58 months, respectively. The 5-year survival rate of corneal allograft was 33%, 4 ± 13.9 in the CLAU applied eyes. In addition, the corneal graft clarity maintenance rate was found to be higher in patients having ≥12 months duration between CLAU and PK, which is statistically significant (62% vs. 23%,P = 0.046).
CONCLUSION: Waiting at least 1 year after CLAU transplantation to perform PK increases corneal clarity. Eyelid problems, even if the eyelids were reconstructed properly, remain a major risk factor for the development of the epithelial disorder in the early and late postoperative period in CLAU applied eyes.
