| Research Abstract |
Intraocular pressure (IOP), aging, gender were selected as a factor that affect the amount of central corneal deformation during tonometry by non-contact tonometer. The aging effect appears more clearly at the late phase of tonometry than the early phase. Female cornea is more susceptible to aging than male. The differences in amount of deformation between ageing groups is more prominent at central cornea, and the difference of corneal deformation at mid-peripheral cornea represented the difference of gender. We also got the result that indicated the IOP reading at low IOP level is lower than actual IOP.
