In patients with unilateral cataract, monofocal, accommodating and partially diffractive multifocal IOL provided higher CS scores when compared with refractive multifocal IOL and in multifocal IOL groups binocular CSs were better than monocular CSs when compared with other groups.
Purpose To compare the short-term changes in corneal endothelial cells after trabeculectomy or XEN Gel Stent implantation. Design Prospective, interventional, comparative study. Methods Changes in corneal endothelium in patients that underwent XEN Gel Stent implantation or trabeculectomy were prospectively evaluated. Eighty eyes of 62 diagnosed with open-angle glaucoma were divided into two the trabeculectomy and XEN Gel Stent groups. Corneal specular microscopy was performed at the central cornea using a noncontact specular microscope preoperatively and 3 months after surgery. Results The baseline mean corneal endothelial cell density in the trabeculectomy group was 2390.3 ± 324.8 cells/mm2, and this was significantly reduced to 2148 ± 352.5 cells/mm2 3 months after surgery, representing a cell loss of 10.0% (p < 0.001). The baseline mean corneal endothelial cell density in the XEN Gel Stent group was 2156.2 ±559.7 cells/mm2, and this was significantly reduced to 2098.4 ± 556.2 cells/mm2 3 months after surgery, representing a cell loss of 2.1% (p = 0.002). The corneal endothelial cell density change rate of the trabeculectomy group (−10.0% ± 9.7%) was statistically higher than the XEN Gel Stent group (−2.1% ± 13.8%) (p = 0.002). A statistically significant difference was observed in the trabeculectomy group between the baseline and postoperative values in the coefficient of variation (p = 0.029). Conclusion Trabeculectomy caused more endothelial cell damage than XEN Gel Stent implantation in the short-term follow-up period. The XEN Gel Stent may be the treatment of choice in patients with a significantly low preoperative corneal endothelial cell density.
Herein, we report 2 cases of endophthalmitis after XEN Gel Stent implantation. A 68-year-old woman and an 80-year-old man had previously undergone uncomplicated XEN Gel Stent implantation for primary open-angle glaucoma 4 and 5 months prior, respectively. Both patients had presented with pain, redness, loss of vision, and sensitivity to light. For both patients, the best-corrected visual acuity was hand motion, eyelids and conjunctiva were hyperemic and edematous, anterior chamber had +3 cells and exhibited hypopyon, and B-scan ultrasonography revealed vitreous condensation. Blebitis was absent; the bleb height was medium, bleb width was 1 to 2 hours, and the bleb was avascular in the first case. In the second case, ∼2 mm of the XEN Gel Stent implant protruded from the conjunctiva; therefore, bleb formation was not observed. On a previous visit, the bleb height was medium, bleb width was 2 to 3 hours, and the bleb was mildly vascular. Both patients had undergone vitrectomy with silicone oil injection, but only the female patient had received intravitreal and topical antibiotics preoperatively. After surgery, both patients received topical antibiotic therapy. After 2 to 3 months, the silicone oil was removed; the final visual acuity remained low for the female patient (hand motion level). Despite immediate treatment, the final visual acuity may remain poor, similar to the outcome of patients with other types of endophthalmitis. It is important to provide the patients scheduled for XEN Gel Stent implantation information on the risk of infection and the other risk factors involved.
Purpose. To evaluate of functional and cosmetic effectiveness of lower eyelid sling technique with fascia lata graft in patients with lagophthalmos due to facial paralysis. Material and Method. Ten patients with a mean age of 55.1 ± 19.77 years who underwent lower eyelid sling surgery with a fascia lata graft between September 2011 and January 2014 were included in this prospective study. Preoperatively and postoperatively patients were evaluated in terms of corneal epithelial defects, Schirmer's test, and tear break-up time (TBUT). Cosmetically, vertical eyelid aperture, margin reflex distances 1 and 2 (MRD1 and MRD2) and scleral show were evaluated preoperatively and postoperatively. Results. One patient had facial paralysis on the right side whereas the other 9 patients had facial paralysis on the left side. Preoperatively, 3 patients were detected with corneal ulcer, whereas 7 patients were detected with persistent corneal epithelial defects localized in the lower half of the cornea. In the 3 patients with preoperative corneal ulcer, the ulcer recovered with corneal opacity, whereas in the 7 patients with punctate epitheliopathy, postoperative corneal transparency was obtained. Discussion. Lower eyelid sling technique with fascia lata graft is an effective technique for the repositioning of the lower eyelid and preventing the corneal complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
