Preliminary outcomes show that DMEK-S may be used in the treatment of corneal endothelial dysfunction. As this approach is entirely manual, and no special surgical equipment is needed, it has the potential to become widely adopted.

Purpose. To evaluate antiangiogenic effect of local use of bevacizumab (anti-VEGF antibody) in patients with corneal neovascularization. Methods. Patients were divided into two groups. All patients suffered from some form of corneal neovascularization (NV). Patients in group A received 0.2–0.5 mL of bevacizumab solution subconjunctivally (concentration 25 mg/mL) in a single dose. Group A included 28 eyes from 27. Patients in group B applied bevacizumab eye drops twice daily (concentration 2.5 mg/mL) for two weeks. Group B included 38 eyes from 35 patients. We evaluated the number of corneal segments affected by NV, CDVA, and the incidence of complications and subjective complaints related to the treatment. The minimum follow-up period was six months. Results. By the 6-month follow-up, in group A the percentage reduction of the affected peripheral segments was 21.6% and of the central segments was 9.6%; in group B the percentage reduction of the central segments was 22.7% and of the central segments was 38.04%. In both groups we noticed a statistically significant reduction in the extent of NV. Conclusion. The use of bevacizumab seems to be an effective and safe method in the treatment of corneal neovascularization, either in the subconjunctival or topical application form.

Purpose: To evaluate the outcomes of the hybrid technique of posterior lamellar keratoplasty (DMEK-S). Materials and Methods: 71 eyes of 55 patients enrolled in a single-center study underwent posterior lamellar keratoplasty with a hybrid lamella DMEK-S implanted using a solution implantation technique, owing to endothelial dysfunction. The outcome measures studied were visual acuity and endothelial cell density. Results: The rate of endothelial cell loss caused by surgery was 43.8%. During followups, we observed the stabilization of postoperative findings, or at minimum a very low rate of corneal endothelial cell loss. The UCDVA and BCDVA dramatically improved postoperatively. The rebubbling rate in our group of patients was 61.9%. We replaced the lamella due to its failure or malfunction in 17 patients (23.9%). Conclusion: In summary, DMEK-S combines the advantages of DSEK/DSAEK and DMEK. The central zone of bare Descemet's membrane and endothelium allows for very good visual outcomes, and the peripheral rim allows for better manipulation of the lamella during implantation. It is an effective method of treating the endothelial dysfunction of various etiologies, but the high complication rate needs to be addressed before widespread implementation of the technique in the future.

PURPOSE: To analyze clinical outcomes of cataract surgery with implantation of a toric intraocular lens (IOL) and to evaluate the effect of capsular tension ring (CTR) presence or absence on the rotational stability of implanted IOLs and postoperative refraction. METHODS: This cohort study included 64 eyes of 41 patients who underwent uneventful cataract surgery with implantation of a toric IOL (enVista toric MX60T; Bausch & Lomb, Rochester, NY) to correct preoperative corneal astigmatism. In 30 eyes, a CTR (11 SR model; Videris s.r.o., Prague, Czech Republic) was co-implanted. Analyzed parameters were refraction, visual acuity, and misalignment of toric lenses. RESULTS: The mean patient age was 67 years (range: 42 to 89 years) and the mean follow-up period was 5 months. Mean manifest astigmatism improved from −1.53 ± 1.15 diopters (D) preoperatively to −0.40 ± 0.61 D postoperatively ( P < .001). Postoperative uncorrected distance visual acuity was 0.10 ± 0.13 logMAR (20/25 Snellen). Mean absolute IOL misalignment was 3.70° with CTR and 3.85° without CTR ( P = .683). In eyes with an axial length of 24 mm or greater, IOL axis matched the planned axis in 90.5% of eyes with CTR and 81.8% of eyes without CTR ( P = .964). Four eyes (6.25%) needed additional surgical IOL rotation. CONCLUSIONS: In eyes after cataract surgery with implantation of a toric IOL, there were no significant differences in the rotational stability of the lens with respect to the presence or absence of CTR. In eyes with an axial length of 24 mm or greater, better IOL alignment was observed in the group with CTR. [ J Refract Surg . 2020;36(3):186–192.]
