Limbal Transplantation for Unilateral Chemical Injuries - Lo
Purpose: To evaluate the long term results of limbal transplantation (LT) in patients with unilateral total limbal stem cell deficiency (LSCD) after chemical injury.

Methods: The study includes 22 eyes of 22 consecutive patients (20 males and 2 females) who presented with total LSCD after unilateral chemical burns and underwent Limbal transplantation (LT) in the Cornea Service of the Department of Ophthalmology at the Heraklion University Hospital in Crete during the period from 1997 to 2014. All 22 cases underwent Conjunctival Limbal autogaft (CLAU) while in 14 surgeries it was combined with amniotic membrane transplantation (AMT). A second stage penetrating keratoplasty (PKP) was performed in 11 cases for visual rehabilitation. The healing time, the changes in VA and the stability of epithelial ocular surface integrity were looked for.

Results: One case failed within 3 months of surgery, while the rest 21 eyes after CLAU maintained ocular surface epithelial integrity during the follow up period (7.8 ± 3.5 years), and showed improvement partially or totally in corneal neovascularization, symblepharon and ocular motility. The mean corneal healing time was 17 days, while visual acuity either showed statistically significant improvement in 18 eyes, with CLAU alone or followed by PKP. No significant difference in the surgical outcome was observed between AMT and none AMT cases.

Conclusions: Conjunctival limbal autografts for limbal deficiency after unilateral chemical burn showed long term success and stability, in 21 out of 22 eyes, whether combined or not with amniotic membrane transplantation
