Kinostat is described as which type of treatment?

• A. Aldose reductase inhibitor
• B. Laser therapy
• C. Drops that dissolve cataracts
• D. Antibiotic drops

Answer: (D)

Kinostat is described as an aldose reductase inhibitor. It works by blocking the enzyme that converts excess glucose into sorbitol in the lens. In diabetes, sorbitol builds up in the lens, creating osmotic stress that contributes to cataract formation. By inhibiting aldose reductase, Kinostat reduces sorbitol accumulation, helping to preserve lens clarity and slow the progression of cataracts.

It isn’t a laser therapy, so it doesn’t remove or reshape cataracts with light energy. It doesn’t dissolve existing cataracts. It isn’t an antibiotic, so it has no antimicrobial effect.
