I have keratoconus in my both eyes. Will I see better after c3r operation?

Perhaps. Depending on the severity of the keratoconus, you may see a small improvement in your uncorrected vision after corneal crosslinking. However, the main purpose of the treatment is not to improve vision but to slow progression of the disease by strengthening the cornea.
Crosslinking. C3r is another name for crosslinking. At our center - we find that 50% of patients achieve 1 or more lines of improvement in vision after crosslinking. Not all patients achieve improvement, but some do. More importantly, crosslinking stops the progression of keratoconus.
