Preoperative Corneal Thickness and Postoperative Visual Outcomes After Posterior Lamellar Corneal Transplant

Relationship Between Preoperative Corneal Thickness and Postoperative

To evaluate the impact of preoperative corneal thickness on visual outcomes following Descemet's stripping endothelial keratoplasty (DSAEK) or Descemet membrane endothelial keratoplasty (DMEK)

Patients underwent DSAEK or DMEK for endothelial dysfunction, from October 2013 to November 2016. Patients aged > 18 years and with an indication for posterior lamellar graft surgery, such as Fuchs dystrophy, were included. Exclusion criteria included a history of penetrating keratoplasty in the study eye and a need for a penetrating keratoplasty following endothelial graft failure. Visual acuity, central corneal thickness (CCT) and graft thickness were measured preoperatively, and at postoperative day 7 and months 1, 3 and 6.

Inclusion Criteria:

• Clinically indicated need for posterior lamellar graft surgery (DSAEK or DMEK) such as:

  • Fuchs dystrophy,
  • pseudophakic bullous decompensation
  • or other endothelial dysfunction corneal

Exclusion Criteria:

• were a history of penetrating keratoplasty in the indicated eye
• the technical inability of preoperative CCT measurement
• the need for a penetrating keratoplasty following endothelial graft failure
• severe postoperative complications resulting in unquantifiable visual acuity
