Title: Innovations by Walter J. Stark: Pioneering Patents in Ophthalmology
Introduction
Walter J. Stark, based in Baltimore, MD, is a notable inventor recognized for his significant contributions to ophthalmology. With two patents to his name, Stark has developed groundbreaking solutions aimed at improving eye health and surgical precision.
Latest Patents
Stark's latest innovations include:
1. **Glucocorticoid-loaded nanoparticles for prevention of corneal allograft rejection and neovascularization**: This invention involves the creation of nanoparticles that encapsulate a glucocorticoid, such as dexamethasone sodium phosphate (DSP), within a biodegradable matrix made of poly(lactic-coglycolic acid) (PLGA). These nanoparticles are coated with hydrophilic polymers like PEG or PLURONIC® F127 and are designed to release DSP sustainably for up to seven days in vitro. This technology has the potential to significantly reduce corneal graft rejection and neovascularization.
2. **Surgical refractive laser calibration device**: In this innovation, a phantom cornea is utilized to calibrate surgical lasers through the superimposition of thin films of alternating colors. The ablation by the laser beam creates a spherical cavity that results in concentric circle patterns, allowing for visual or instrumental analysis to ensure accurate laser settings. The calibration cornea is designed to mimic natural corneas, and can be mounted in a phantom eyeball for enhanced precision during laser alignment.
