In Vivo	Right eyes of the rabbits (male grey chinchilla rabbits aged 3-4 months weighing 2-3 k) are instilled with 80 μL of formulation A containing 1 % N-Acetylcarnosine. The N-Acetylcarnosine prodrug eye drops optimize the clinical effects for the treatment of ophthalmic disorders (such as prevention and reversal of cataracts in human and animal eyes)[1].
