Optical coherence tomography features of the graft–host junctions after deep anterior lamellar keratoplasty: Long-term changes [PDF]

open access: yesIndian Journal of Ophthalmology
Purpose: The wound healing process in the graft–host junction (GHJ) after deep anterior lamellar keratoplasty (DALK) can affect the outcome. We studied the anterior segment optical coherence tomography (OCT) features of the GHJ in the early and late ...
