Optimized Ocular Models Focused on Improving Outcomes

Our nonclinical ocular models include in vivo and ex vivo options for implants, small and large molecules. Absorption Systems provides specialized tissue-based ADME ocular models that can provide a comprehensive study from design to testing to endpoint analysis using conditions optimized for your compound.

All animal studies are performed in our 50,000 sq. ft. AAALAC-accredited, GLP-compliant and NIH-assured vivarium located in San Diego, CA. We have experience with species such as rabbit, pig, dog, and sheep plus disease models including glaucoma, AMD, KCS, CNV and more. Learn more about our ophthalmic research programs below.
