You get a new save every day to remove the curse :)
Evil Eye (Su) Three times per day, a sea hag can cast her dire gaze upon any single creature within 30 feet. The target must succeed on a DC 14 Will save or be staggered as strange nebulous distress and a gnawing sense of impending doom plagues the victim. If a sea hag uses her evil eye on someone already afflicted by this curse, the victim must make a DC 14 Fortitude save or be overwhelmed with fright and collapse into a comatose state for 3 days. Each day that passes, the comatose victim must make a DC 14 Fortitude save or perish. The evil eye is a mind-affecting fear effect. The save DCs are Charisma-based.Evil Eye Curse: Gaze—failed save; save Will DC 14; frequency1/day; effect staggered (or fall comatose if already under the effects of the evil eye).
Actually, now I'm not sure you get a new save each day to cure the effect since the affliction entry doesn't list a cure entry. The victim might be stuck staggered forever until they get uncursed.
I just looked this up because I have decided 3 hags in a coven worshipping Treerazer have jailed the dryad Arlantia in her huge old tree. One is a sea hag, the other a green hag and they are led by an Annis Hag. I decided it is permanent until you get a remove curse. The main worrying thing for me is if one of them gets killed by her evil eye.
