Rational:~SLT has known transient effect on corneal endothelial cell (CEC) counts yet no data is yet available with DSLT.~This study is relevant as the DSLT treatment area is at the limbus: CEC progenitor site
The objective of this study is to compare the long-term (6 months) effects of Direct Selective Laser Trabeculoplasty (DSLT) treatment and SLT (Selective Laser Trabeculoplasty) treatment on corneal endothelial cell counts and corneal thickness.
