Glaucoma is an eye disease that a person can have but not know until their vision is severely affected. If untreated, the condition progresses steadily, causing vision loss and irreversible blindness. Glaucoma has no cure but catching it early can preserve your vision. So, acting early before the disease causes lasting damage is paramount.

Orthokeratology, also called ortho-k, is transforming the treatment of nearsightedness and other refractive errors. Patients no longer must wear glasses and contact lenses or undergo corrective eye surgery. With ortho-k, optometrists can help patients correct their vision using only specialty contact lenses.
