Hi doctor, what is the best way to reduce intra-occular pressure and treating corneal arcus?

Separate issues: If your intraocular pressure (iop) is elevated you must have had an evaluation since you cannot measure this except with equipment in an ophthalmologists office. If elevated it will respond to anti-glaucoma drops and laser or surgery if these don't work. Corneal arcus is in the substance of the peripheral cornea and there is no known treatment although it usually will not affect vision.
