"Recently, a study of lanosterol, a precursor to cholesterol , and a closely related sterol  can reverse lens vibration in vivo in drip application. The effect is believed to be due to the activation of protective proteins in the lens that counteract aggregation of water-soluble proteins. The find is very exciting even though more work remains."
