Synthesis of Soft Polysiloxane-urea Elastomers for Intraocular Lens Application

This study describes synthetic routes for aminopropyl-terminated polydimethylsiloxanes and polydimethyl-methyl-phenyl-siloxane-block copolymers and for soft polysiloxane-based urea (PSU) elastomers. It presents the application of PSUs as accommodating an intraocular lens. An evaluation method for in vitro cytotoxicity is also...

Induction of Elevated Intraocular Pressure in a Rat Model

Source: Lani-Louzada, R., et al., Full-Circle Cauterization of Limbal Vascular Plexus for Surgically Induced Glaucoma in Rodents. J. Vis. Exp. (2022)This video demonstrates the induction and monitoring of elevated intraocular pressure (IOP) in a rat model. The process involves cauterizing the limbal blood vessels, resulting in vessel occlusion and elevated IOP. The rat is then allowed to recover, and IOP is regularly monitored in both the experimental and control eyes for...

Subretinal Implantation of RPE on a Carrier in Minipigs: Guidelines for Preoperative Preparations, Surgical Techniques, and Postoperative Care

The subretinal implantation of retinal pigmented epithelium (RPE) is one of the most promising approaches for the treatment of degenerative retinal diseases. However, the performance of preclinical studies on large-eye animal models remains challenging. This report presents guidelines for the subretinal transplantation of RPE on a cell carrier into...
