“…Since DLEK requires additional recipient stromal dissection, we expected that the DSEK group would experience less interface opacity and have better contrast sensitivity. In a previous study, the mean contrast sensitivity was found to be similar between candidates undergoing penetrating keratoplasty and deep anterior lamellar keratoplasty [22]. Due to the dearth of other studies directly comparing the postoperative interface opacity and contrast sensitivity after DLEK and DSEK, further studies are required if definitive conclusions are to be reached.…”

PurposeTo compare clinical outcomes after deep lamellar endothelial keratoplasty (DLEK) with Descemet stripping endothelial keratoplasty (DSEK) performed as initial cases by a single surgeon.MethodsSixteen patients with corneal endothelial were enrolled. Eight patients (8 eyes) underwent DLEK and 8 patients (8 eyes) DSEK. We measured uncorrected visual acuity, best corrected visual acuity (BCVA), manifest refraction, corneal endothelial count, interface opacity via Schiempflug imaging, and contrast sensitivity, as well as tracked postoperative complications over the first postoperative year.ResultsPrimary graft failure occurred in two DLEK cases and one DSEK case, all of which were excluded for further analysis. The average 12-month postoperative BCVA was 20/70 in the DLEK group and 20/50 in the DSEK group, with the difference not statistically significant. No significant differences were identified between the 2 groups in terms of mean spherical equivalent and refractive astigmatism, although individuals in the DSEK group tended toward hyperopia. The average endothelial cell count at postoperative month 12 was 1849±494 in the DLEK group and 1643±417 cells/mm2 in the DSEK group, representing cell losses of 26.2% and 31.9%, respectively. No significant differences in endothelial cell count or endothelial cell loss were observed between groups. Early postoperative donor disc dislocation occurred in two eyes after DLEK and one eye after DSEK. Interface opacities and contrast sensitivities were similarly not significantly different between groups.ConclusionsNo significant differences in any assessed clinical outcome were observed between individuals undergoing DLEK and DSEK, when performed as initial cases by a single surgeon.

“…Keratoconus was the main indication for corneal transplantation (36.09%), similar to a study conducted in the city of Florianópolis where 28.7% of transplants had this indication (5) . Keratoconus is a bilateral corneal ectasia typically affecting older teens and young adults (26) , which corresponds to the mean age for the disease found in our study (31 ± 10.73 years) and also in Garcia et al (27.2 years) (5) , Al-Yousuf et al (32.5 ± 11.70 years) (7) , Maeno et al (34.43 years) (17) , and Edwards et al (31.8 years) (21) .…”
