To report anterior segment Optical Coherence Tomography (AS OCT) findings and results of Descement Stripping with Automated Endothelial Keratoplasty (DSAEK) combined with phacoemulsification in cataract patients with Fuchs’ endothelial dystrophy
Twelve eyes of eleven patients (one after bilateral procedures) with at least one year follow-up were reviewed. Measured parameters included best spectacle corrected visual acuity (BSCVA), refractive spherical equivalent (SE) and predictability, anterior corneal keratometric values, complications, and AS OCT findings.
Mean follow up was 14.33 months (range, from 12 to 18 months). BSCVA was unchanged (8%) or improved (92%) in all eyes compared with the preoperative levels. A discrepancy between the targeted postoperative refraction and the actual postoperative spherical equivalent (SE) refraction (hyperopic shift) of +1.46 D+ 0.76 D (range, -0.05 to +3.14) was observed. There was a significant correlation between the ratio of central versus the average peripheral donor corneal lenticule thickness (described as Central/Peripheral ratio at 3mm zone) and induced hyperopic shift (r=-0.81, p=0.001).
DSAEK combined with phacoemulsification and IOL implantation in patients with coexisting Fuchs’ endothelial dystrophy and cataracts improved BSCVA without progressive time-dependent complications. There is a correlation between donor corneal lenticule shape and induced hyperopic shift.
