There are certain guidelines for reservation under physically handicapped quota given by the government and MCI, which are as follows:

3% horizontal reservation for 15% AIQ

This reservation is mainly for candidates for lower limb (motor) disability of 50-70 % (PH1)

If these reserved seats remain vacant then candidates with lower limb disability between 40 and 50% are considered (PH2)

PH reservation does not include visual or forelimb (arms and hands) impairment. I'm afraid you can not avail this quota.
