Objective: To report opacification of hydrophilic acrylic and silicone foldable intraocular lenses (IOL). Designs: Case series. Participants: Five patients with IOL opacification. Results: We report five eyes of five patients with late opacification of the intraocular lens (IOL). Three patients had hydrophilic acrylic (SC60B-OUV-MDR, Inc), two had silicone IOL (Allergan SI30NB). Two out of the ...

QuickSite (St Jude Medical, Sylmar, CA, USA) is a silicone and polyurethane-insulated coronary sinus pacing lead. Riata lead (St Jude Medical, Sylmar, CA, USA) is a silicone insulated right ventricular shock lead. Recently, insulation breach of silicone based leads raised a huge concern. Fluoroscopic examination of these two leads in the same patient revealed externalization of these two leads....

Silicone oil use as an adjunct to complicated vitreoretinal surgery is becoming more frequent. Refractory glaucoma in these patients is common. Isolated reports have mentioned the possibility of silicone oil migrating and/or obstructing the tube in the anterior chamber of Molteno implants (IOP, Costa Mesa, Calif). This report describes a case of intraocular silicone oil egressing through an Ahm...

L'hypopion inverse se voit parfois après une vitrectomie postérieure avec tamponnement par de l'huile de silicone, quand l'huile s'émulsifie, il passe dans la chambre antérieure et s'installe au sommet de la chambre antérieure. Comparer à l'hypopion où les leucocytes se précipitent au fond de la chambre antérieure ; et ceci est dû à l'effet de gravité, d'où le nom d'hypopion inverse. Le traitem...

BACKGROUND AND PURPOSE As part of a multicenter cooperation (Aneurysm-Like Synthetic bodies for Testing Endovascular devices in 3D Reality) with focus on implementation of additive manufacturing in neuroradiologic practice, we systematically assessed the technical feasibility and accuracy of several additive manufacturing techniques. We evaluated the method of fused deposition modeling for the ...

OBJECTIVES To investigate the activities of two newer triazoles and two echinocandins combined with human phagocytes against Candida parapsilosis biofilms. METHODS An in vitro model of C. parapsilosis biofilms was used. Biofilms were grown on silicone elastomer discs in 96-well plates at 37°C for 72 h. Biofilms or planktonic cells were incubated with voriconazole, posaconazole, caspofungin or...

A dissolved methane sensor based on silicone tube was designed, constructed and optimized.The silicone tube diameter, silicone tube length and helium flow rate (as the carrier gas(were considered as process parameters to be optimized.A continuous stream of helium (50 mL/min) was directed through the tubing, sweeping out the...

AIM To investigate whether the emulsification of conventional silicone oils can be reduced by adding small amounts of silicone molecules of a very long chain length. METHODS Siluron 1000, Siluron 2000, Siluron 5000, Acri.Sil-Ol 5000, Oxane 5700, Densiron 68 LV, Densiron 68 and Densiron 68 HV (0.5 ml) were each tested along with either plasma or serum (0.5 ml) in a glass cuvette. Emulsificatio...

AIM To examine the histology of preserved anterior lens capsule in vitrectomised and lensectomised rabbit eyes with and without silicone oil tamponade. METHODS Forty adult Japanese albino rabbits received two port vitrectomy and lensectomy with or without silicone oil tamponade in one eye under both general and topical anaesthesia. Anterior lens capsule was preserved during operation. After h...

OBJECTIVE To quantitatively compare the extent of posterior capsule opacification (PCO) after polymethylmethacrylate (PMMA), silicone, and soft acrylic intraocular lens implantation. PATIENTS AND METHODS A total of 240 eyes from 240 patients undergoing implant surgery were randomized into 3 groups based on the type of lens implanted: PMMA, silicone, and soft acrylic. The density value of PCO ...
