[Patient satisfaction after posterior lamellar keratoplasty (DSAEK)].
BACKGROUND
The advantages of posterior lamellar keratoplasty (DSAEK) compared to conventional full thickness keratoplasty are faster visual rehabilitation, little change in astigmatism and the absence of suture-associated complications. The current study evaluated the satisfaction of the first 15 patients who underwent DSAEK at our clinic.


METHODS
Evaluation of patient satisfaction was conducted via a telephone survey and by means of a written patient questionnaire. The patients were asked to answer questions on a scale from 1 (very bad) to 10 (very good) about their overall satisfaction with this procedure, their satisfaction with the achieved postoperative visual acuity, their satisfaction with the progress of the healing process and the extent of the perceived burden. The patients were also asked whether they would opt again for the operation. Pre- and postoperative visual acuity, IOP, topographic astigmatism and corneal pachymetry were analysed.


RESULTS
15 eyes of 15 patients were analysed (12 women and 3 men). Average age at the time of operation was 75 +/- 7 years. Visual acuity increased and corneal thickness decreased primarily within the first three months. During that time there was an increase in overall patient satisfaction which finally reached 6.9 +/- 1.8 on the scale. Postoperative visual acuity was awarded with 7.2 +/- 2.0, progress of the healing process with 7.4 +/- 2.3. The procedure was not perceived as a big burden (8.0 +/- 1.9) and most patients would have decided again for the operation (8.2 +/- 2.0). There was no pre- and postoperative difference in IOP and corneal astigmatism.


CONCLUSIONS
Like in our group patients with diseases of the corneal endothelium are of higher age and therefore benefit from a fast restitution of visual acuity and a low burden of operation. DSAEK represents a secure and practical procedure to rehabilitate elderly patients with diseases of the corneal endothelium.
