One-year results and anterior segment optical coherence tomography findings of descemet stripping automated endothelial keratoplasty combined with phacoemulsification

Objective: To report 1-year results and anterior segment optical coherence tomography findings of Descemet stripping automated endothelial keratoplasty combined with phacoemulsification in patients with cataract and Fuchs endothelial dystrophy. Methods: Twelve eyes of 11 patients with at least 1-year follow-up were retrospectively reviewed. Measured variables included best spectacle-corrected visual acuity, refractive spherical equivalent and predictability, anterior corneal keratometric values, complications, and anterior segment optical coherence tomography findings. Results: The mean follow-up was 14.33 months (range, 12-18 months). The best spectacle-corrected visual acuity was unchanged (8%) or improved (92%) in all eyes compared with the preoperative levels. A mean (SD) discrepancy between the targeted postoperative refraction and the actual postoperative spherical equivalent refraction (hyperopic shift) of 1.46 (0.76) diopters (D) (range, -0.05 to 3.14 D) was observed. A significant correlation existed between the ratio of central graft thickness to mean peripheral donor corneal lenticule thickness at 3mm and induced hyperopic shift (R²=0.65, P<.001). Conclusions: Descemet stripping automated endothelial keratoplasty combined with phacoemulsification and intraocular lens implantation in patients with coexisting Fuchs endothelial dystrophy and cataract improved best spectacle-corrected visual acuity without progressive time-dependent complications. A correlation exists between donor corneal lenticule shape and induced hyperopic shift.
