Intracameral air bubble tamponade in routine cataract surgery

Abstract

Purpose: To evaluate the efficiency, safety, and postoperative outcomes of intracameral air bubble tamponade (IABT) following phacoemulsification cataract surgery.Methods: We retrospectively reviewed all patients receiving phacoemulsification from 2016 to 2017 performed by one ophthalmic surgeon HCC. Incisions were closed with either non-IABT or IABT. In IABT group, air bubble was injected into the anterior chamber until its size reached 80% of the corneal diameter. Operation time, visual acuity (VA), and intraocular pressure (IOP) were evaluated pre- and post- operatively. Patients with intraoperative complications or with ocular diseases that may affect VA or IOP were excluded. Results: A total of 434 eyes of 331 patients were enrolled, with 201 cases in the IABT group and 233 cases in the non-IABT group. The operation time was significantly shorter in the IABT group (1365 vs. 1514 seconds, P= .005). There was no significant difference in logMAR VA (P=0.639) and IOP (P=0.860) between two groups in preoperative, postoperative 3 days, 10 days, 1 month, and 3 months. In 168 cases that had complete data of pre- and post-operative specular microscope examination, secondary analysis showed no significant difference in pre- and post-operative endothelial cell density, coefficient of variance, and hexagonal cells between both groups. Conclusion: IABT is a safe and effective method for sealing clear corneal incision in phacoemulsification cataract surgery.

Probiotic effects of Lacticaseibacillus rhamnosus 1155 and Limosilactobacillus fermentum 2644 on hyperuricemic rats

“…Although this disease afflicts humans for years, the clinical drugs currently use for urate-lowering therapies are limited and most of them are considered to be associated with various adverse effects (13,15). Probiotic treatment might be a promising strategy for anti-hyperuricemia intervention (22)(23)(24)(25). In this study, we revealed that LR1155 and LF2644 isolated from Chinese traditional fermented dairy food exhibited an antihyperuricemia effect, and the underlying mechanism for each strain was testified.…”

“…Gut microbiota dysbiosis caused by hyperuricemia was regulated by supplementation of L.brevis DM9218 or L. fermentum JL-3 (23,24). Moreover, microbial fermented extracts of Lactobacillus were reported to prevent the UA elevation by inhibiting the XOD activity (25). However, whether the LAB strains may play a role in the aspect of UA excretion effects has not been clarified.…”
