PetVision NAC Formula Pet Cataract Eye Drops, (10ml x 2)

An eye drop for canine cataracts featuring a highly effective corneal penetration formula. Utilizing optimized N-acetylcysteine (NAC) special molecular technology, it quickly penetrates the corneal barrier to reach the lens, performing a dual action of antioxidation + protein repair. This effectively slows down cataract deterioration and improves lens transparency.

Mechanism of action of N-Acetylcysteine:

Protein dissolution: Breaks disulfide bonds in denatured lens proteins, reversing protein aggregation caused by oxidative stress.
Free radical scavenging: Inhibits lipid peroxidation, reducing damage to lens epithelial cells by reactive oxygen species.
Mucin regulation: Improves tear film stability, alleviating dry eye discomfort in dogs.

Mechanism of action of Lanosterol:

Dissolves aggregated denatured proteins: Destroys the cross-linked structure of abnormal proteins, particularly the aggregation of α-crystallin, restoring transparency to the cloudy lens. Studies show that Lanosterol can reduce light scattering in cataractous lenses by 40-60% (Nature, 2015).

Inhibits protein denaturation: Lanosterol stabilizes lens proteins, reducing denaturation caused by oxidative stress, enhancing antioxidant capacity within the lens, and minimizing free radical damage.

Promotes self-repair of the lens: Stimulates lens epithelial cells to repair damaged proteins and maintain normal metabolic function.

In canine experiments conducted by the Department of Veterinary Medicine at the University of Cambridge, daily use of the NAC formula three times a day resulted in a significant reduction in immature cataracts and nuclear sclerosis opacity index after eight weeks.
