1. Ophthalmic drugs are able to bind to melanin and accumulate in ocular tissues, causing ocular toxicity. On the other hand, the binding of ophthalmic drugs to melanin can also increase drug targeting for the delivery system of ophthalmic drugs. Therefore, studies evaluating the ability of new ophthalmic drugs to bind to melanin are essential in the development of new ophthalmic drugs.

2. In ophthalmic drug administration, the cornea acts as a barrier and can limit the absorption of topically administered drugs. Therefore, studies to evaluate the permeability of new drugs in the cornea are essential in the development of new ophthalmic drugs.
