Graft asymmetry index was calculated in four semimeridians (0°, 90°, 180° and 270°) using anterior segment optical coherence tomography (AS-OCT): (a) in the axis of 0 and 180 degree, (b) in the axis of 90 and 270 degree

Purpose
To compare the visual outcomes, postoperative complications, and graft asymmetry between precut and manually dissected donor tissues for Descemet stripping automated endothelial keratoplasty (DSAEK) and Descemet stripping endothelial keratoplasty (DSEK) procedures, respectively.
Methods
Seventy eyes of 70 patients undergoing DSEK/DSAEK at...

... were performed in four semimeridians (0°, 90°, 180°, and 270°) to account for graft asymmetry. An estimate of graft asymmetry was obtained by calculating a graft asymmetry index, given by the maximal peripheral graft thickness divided by minimum peripheral graft thickness. the peripheral thickness was determined as 1 mm from the graft edge [ Fig. 1] to minimize the influence of edema at the edge of the lamellar graft. [7] The graft asymmetry index was measured at each follow-up visit at postoperative day 1, 1 week, 1 month, 3 months, and 6 months. The lenticule thickness was measured using Visante OCT (Carl ...
