Comparison of Femtosecond Laser-Enabled Descemetorhexis and Manual Descemetorhexis in Descemet Membrane Endothelial Keratoplasty

Conclusions: FE-DMEK shows efficacy similar to that of M-DMEK with apparently less graft detachment and reduced need for rebubbling.

Conclusions: DWEK induces an increased central posterior float localized to the site of Descemet membrane stripping, confirming the need for centralized stripping. Irregular astigmatism can occur after DWEK but is typically minimal and occurs more commonly in the setting of preoperative irregular astigmatism. DWEK induces about a 0.5 D hyperopic shift, which should be considered when determining intraocular lens power with simultaneous surgery.

This study prospectively evaluated the use of ripasudil in patients undergoing DSO for FD. Methods: Enrolled patients underwent DSO with or without cataract surgery, performed by 1 surgeon. On the first postoperative day, patients were assigned to topical ripasudil 0.4% (Glanatec) 4 times a day for 2 months or no ripasudil and followed up monthly for the first 6 months and then at 9 and 12 months after surgery. Endothelial cell density (ECD) and pachymetry were evaluated at each postoperative visit. Results: Eighteen patients were enrolled, including 8 women and 1 man in each group. Overall, patients who underwent DS...

Conclusions: Our study demonstrates no difference in DMEK outcome with regard to rebubble rate whether the procedure is performed in combination with cataract surgery, in pseudophakia, or in phakia. Furthermore, donor age, initial graft cell count, and graft preparation technique did not impact rebubble rate. BCVA was also not affected by the need for rebubbling.

Conclusions: Increased IOP at 2 hours is common after DMEK, but does not seem to influence early endothelial cell survival. One-month ECD was influenced by donor counts and combined cataract surgery.

In this study, postoperative intraocular pressure (IOP) is investigated in this regard. Methods: In total, 1047 DMEK procedures in patients with Fuchs endothelial dystrophy or bullous keratopathy were reviewed. All rebubbling procedures were recorded as well as postoperative IOP values (first measure 2 hours postoperatively and highest and lowest value within 3 days after surgery), donor factors (donor age, organ culture time, and endothelial cell count), and whether DMEK surgery had been combined with cataract surgery (triple-DMEK). Incidence rates were estimated with the Kaplan–Meier method. Cox regression was u...

Conclusion: Descemet membrane endothelial keratoplasty is a safe and effective procedure in several types of endothelial diseases among Indian patients with encouraging surgical and visual outcomes. Complications are less and endothelial cell loss percentage is acceptable. PMID: 30123378 [PubMed]
