Thinning of donor graft after conventional Descemets stripping automated endothelial keratoplasty

Purpose: Purpose of this study is to evaluate postoperative deturgescence of lamellar donor graft after conventional Descemet’s stripping automated endothelial keratoplasty (DSAEK). Setting: All patients were operated and evaluated at Department of ophthalmology, University Hospital Center Zagreb, Croatia. Methods: It was prospective study that included 55 eyes of patients (mean age 70, 9 ± 9, 4 years ; female 61, 8%, male 38, 2%) who undergone DSAEK keratoplasty. Preoperative thickness of lamella measured by pachimetry in eye bank was compared with postoperative thickness measured with anterior ocular coherence tomography (a-OCT) six months after surgery. Results: Central lamellar graft thickness decreased from 142 ± 27 µm preoperatively to 124 ± 20 µm 6 months postoperatively (p<0, 01). After performing conventional DSAEK corneal transplantation, surgeons should expect deturgescence of corneal graft and reduction in thickness of lamellae about 12% of initial thickness according to our results. Conclusion: It is important to know value of postoperative thinning of lamellae for better planning of surgical procedures and knowing what to expect after surgery, and also for better cooperation with eye banks when ordering precut corneal tissue.
