Case selection for simple limbal epithelial transplantation (SLET). Ideal cases for SLET are those of unilateral total limbal stem cell deficiency (LSCD) with wet ocular surface, without eyelid pathologies, with minimal symblepharon, and with relatively clear underlying corneal stroma (a to d). Cases satisfying all the above criteria but with advanced symblephara will need both SLET and conjunctival autografting (CAG) from the healthy eye (e to h). Cases of pterygium, partial LSCD, or pseudopterygium are best treated with ipsilateral or contralateral CAG without SLET (i to l). Cases of total LSCD associated with dry ocular surface, keratinization, entropion, adherent leukoma, and anterior staphyloma are not amenable to SLET or CAG and will need more complex procedures like keratoprosthesis (m to p)
