20 years old with current spectacle's prescription (2 years ago) of -3.00DS both eyes. Recently, went for eye examination and found out she is having uncorrected low astigmatism ( -1.00DC X180 ) both eyes. With keratometry, it can be seen that the corneal astigmatism having power of -1.00DC. What causes increase in corneal astigmatism over the last 2 years? thank you =)
