2. Purpose
To report the long term results of Descemet Stripping and Automated Endothelial Keratoplasty (DSAEK) in patients with failed penetrating keratoplasty (PKP)

3. Patients & methods
A retrospective, consecutive, non-randomized cohort study, IRB approved
Undertaken in the cornea clinic at the Toronto Western Hospital, Toronto, Ontario, Canada
All records of all patients who had failed PKP and underwent DSAEK were reviewed

4. Results Study group, 10 pts
M / F: 6 / 4
Mean Age: 71.6 y/o (Range 53-89)
OD / OD: 3 / 7
All patients had PKP 6.92 years prior to DSAEK (Range )
One patient underwent cataract extraction with IOL implantation at the same time with DSAEK
Mean follow-up: 18.4 month (Range 3-29) .

5. Results Study group, 10 pts
Reasons for original PKP
Number of Pts.
PBK / ABK 4
Fuch's dystrophy 2
Glaucoma with shunt in A/C
ICE syndrome 1
Trachoma scars .

6. Results Post. Operative period
Descemet membrane was stripped in all cases, no complication during surgery
IOP rise in the postoperative period was noted in three cases

7. Results At the end of F/U.

8. Results
2 years post DSAEK .

9. Results Best Spectacle Corrected Visual Acuity (BSCVA)
Log MAR (Range)
Preoperative
2.22 ( 1.5 – 3 )
Three month after surgery
1.38 ( 0.3 – 3 )
End of follow-up
1.63 ( 0.3 – 3 )
Vision is limited in some patients by:
Advanced glaucoma
Macular scar

10. Conclusions
Doing a DSAEK operation for failed PKP is not more complicated then regular DSAEK operation
The rate of postoperative detachment and complication is higher
