Purpose: While endothelial keratoplasty has become the standard treatment for Fuchs dystrophy, the strategy for first-line surgery in patients with associated cataract is still debated. The purpose of this study was to evaluate the surgical outcomes of eyes with Fuchs endothelial corneal dystrophy (FECD) undergoing phacoemulsification alone, to ascertain preoperative factors that predict the need for endothelial keratoplasty (EK)., Methods: Single-center retrospective study. Cataract surgery alone was performed in 64 eyes of 50 patients with FECD. This decision was made if the patient did not have morning blur, the central corneal thickness (CCT) was below 630 microns, and endothelial cells were visible in the periphery., Results: Mean follow-up was 21 months (range 5-55 months). The mean preoperative CCT was 571±43μm. 6 months after surgery, it was 584±52μm (P=0.12). During follow-up, 14 eyes (22%) required an EK because of poor visual outcome after cataract surgery alone. Mean pre-operative CCT of these eyes (595±23μm) was significantly higher than eyes that did not require EK during follow-up (564±45μm, P=0.022). Over 570 microns, 34% of eyes required an endothelial keratoplasty after the cataract surgery alone., Conclusions: CCT below 630μm associated with the absence of morning blur are preoperative criteria allowing 78.1% eyes with FECD to obtain good visual outcomes after cataract surgery alone. In these eyes, EK can therefore be avoided while ensuring good results., (Copyright © 2021. Published by Elsevier Masson SAS.)

Purpose: Descemet membrane endothelial keratoplasty (DMEK) combined with cataract extraction and intraocular lens insertion (new triple procedure) limits postoperative refractive errors. The objective of this study was to assess refractive accuracy after DMEK combined with cataract extraction and intraocular lens implantation., Setting: Four university hospitals (Rouen, Paris, Reims, Grenoble)., Design: This retrospective multicenter study included patients with symptomatic corneal endothelial decompensation and cataract., Methods: The primary outcome was the difference between the target spherical equivalent and postoperative refraction at months 2 and 6. Secondary outcomes were visual acuity, keratometry, pachymetry and endothelial cell density., Results: A total of 130 eyes of 111 patients (mean age 66.2 years) were included (94% with Fuchs' endothelial dystrophy). For a mean refractive target set at -0.50 (±0.57) D, the mean (95% CI) refractive error was hyperopia of +0.49 (0.314; 0.664) D at 2 months and +0.46 (0.299; 0.619) D at 6 months. Best corrected distance visual acuity was improved in all patients: from 0.49 (±0.3) logMAR to 0.14 (±0.14) logMAR at 2 months and 0.05 (±0.1) logMAR at 6 months. Mean corneal thickness decreased from 621.6 (±37.6) μm to 515.2 (±42.6) μm at 2 months and 539.0 (±39.0) μm at 6 months., Conclusions: Good refractive accuracy was obtained after the new triple procedure with DMEK. Hyperopic shift is common after triple procedures, and its persistence should be evaluated in future studies in order to anticipate a change in its value to optimize intraocular lens power calculation., (Copyright © 2021 Elsevier Masson SAS.
