Dear Candidate though it is very hard to admit but if you have already dreamt of becoming an IPS/IAS officer then you have to pass both physical and mental health checkups. However if your keratoconus is under curable condition then you can opt for both the jobs unless your vision is blurred. But if the condition is too severe to degenerate the corneal tissues then you may not achieve the fitness certificate for selection.

Hope you get well and fulfill your dream

Good luck!!!
