Engineered for Ocular Innovation

Key Attributes of the Hydrogel Platform

Our hydrogel technology is a versatile platform employed to create sustained-release therapies that may expand treatment options across multiple ocular conditions.

The hydrogel delivery technology enables creation of sustained release dosage forms of drugs that have been previously approved by the FDA when formulated as drops or injections.


Low Potential for Inflammation
90% water, biocompatible. No presevatives
Steady state or tapered delivery. Release in days or months.
Small molecules or large proteins. Usable in several locations within the body.
Fully absorbs when drug is delivered. Remains visible for monitoring. Delivered with small-gauge needle or forcepts.
Robust portfolio of patents. Proprietary. Non-standard dosage forms.


Sustained Release Drug Delivery

Our proprietary hydrogel platform is engineered to create soft, biocompatible therapeutics that provide sustained and localized drug delivery.1-4 The goals of localized drug delivery are to facilitate targeted delivery of a drug and minimize systemic exposure.2,5

The hydrogel is a biodegradable polyethylene glycol (PEG)1 network and is preservative free. This hydrogel network is a meshwork that entraps the drug particles.1 When administered, the PEG network hydrates with water, then the drug particles begin to dissolve, diffusing the drug outward from the hydrogel into the surrounding local tissues.1 Following the completion of drug delivery, the hydrogel biodegrades and is cleared from the body.1,6,7

The company’s novel technology can be formulated to provide sustained release from days6,7 to months3,4 depending on the treatment required. The versatile hydrogel platform can be used to deliver both small molecules7 and large proteins at both small and large molecular weights.6,7
