To evaluate the results of using and removing silicone oil in the management of giant retinal tears, 24 cases of vitrectomy with fluid-silicone oil exchange were reviewed. We did not use cryotherapy in any case. For chorioretinal adherence, we used either endolaser or postoperative external laser and a narrow buckle. The retina was reattached successfully in 22 (91.6%) of the 24 eyes. Of these, visual acuity was 20/200 or better in 18 (75%) eyes. This was significantly better than the preoperative visual acuity (P = .02). After removing the silicone oil in 15 cases, 13 (92.8%) had visual acuities of 20/200 or better, which was considerably better than that of the group in which the silicone oil was not removed (P = .006). We recommend removing the silicone oil and additional peeling of membranes an average of six months postoperatively when the eye is stable.

Surface Fluorination of Silicone Rubber with Enhanced Stain Resistance and Slip Properties.

Silicone rubber (SR) holds significant potential for everyday wearable devices due to its inherent sweat resistance and flexibility. However, its broader applicability is constrained by poor oil resistance and a suboptimal slip performance. In this study, we developed an SR with durable oil resistance and enhanced slip properties by forming a covalently bonded barrier layer on its surface through a one-step in situ fluorination reaction using F/N.

The effectiveness of ultraviolet-C light-emitting diodes (UVC LEDs) is currently limited by the lack of suitable encapsulation materials, restricting their use in sterilization, communication, and in vivo cancer tumor inhibition. This study evaluates various silicone oils for UVC LED encapsulation. A material aging experiment was conducted on CF1040 (octamethylcyclotetrasiloxane), HF2020 (methyl hydro polysiloxanes), and MF2020-1000 (polydimethylsiloxane) under UVC radiation for 1000 h.

This study evaluates the performance of continuous flow and drop-based microfluidic devices for the synthesis of silver nanoparticles (AgNPs) under identical hydrodynamic and chemical conditions. Flows at low values of Dean number (De < 1) were investigated, where the contribution of the vortices forming inside the drop to the additional mixing inside the reactor should be most noticeable. In the drop-based microfluidic device, discrete aqueous drops serving as reactors were generated by flow focusing using silicone oil as the continuous phase.

Purpose: To characterize the anterior segment (AS) morphology of patients with long-term silicone oil (SiO) in situ (> 12 months) following pars plana vitrectomy (PPV).
Methods: This prospective, comparative characterization study was conducted between January 2022 and July 2023. Patients were included and sorted based on if they had undergone PPV without long-term SiO or had SiO in situ for at least 12 months at the time of review and image collection.
