A procedure called Corneal Collagen Cross Linking was performed on the left eye.
The glasses prescriptions then was:
Right Eye: -1.25DS/-3.00DC*170 and
Left Eye: -2.50DS/-3.50DC*150
I was diagnosed to have a condition called KERATOCONUS in 2011, which is more severe in the left eye and very mild in the right eye.
Due to the fact that my prescriptions has a wide range of difference between the two eyes as:
Old Prescription: Right Eye: -1.25DS/-3.00DC*170 & Left Eye: -2.50DS/-3.50DC*150 and
New Prescription: Right Eye: -3.5D & Left Eye: -4.00/-1.00*90.
Please, kindly advice if it is safe for me to go ahead and use the new prescribed glasses? and also to know if there is any improvement in my eyes based on comparison between the old and the new prescriptions?
Thanks for your Question
There are significant differences between the old and the new prescription. You have to re-check that with your optometrist again.
You shouldn't wear this new eyeglass unless you double check that with your optometrist. Wearing eyeglass with wrong prescription can cause headache and eye strain.
