Success rate of transprk is good. A generalised statement saying perfect vision is not guaranteed would be wrong. Yes it might take few days for the vision to get to perfect 6/6. But case selection and proper planning plays a role. So in all transprk is a safe and effective refractive procedure which I would recommend after evaluating the patient.
Next Steps
Consult a refractive surgeon to get properly evaluated before going in for any procedure.
Health Tips
Getting evaluated by a refractive surgeon is must. Donot make decisions on other patients experience. Every patient is different.
