If your eye pressure is higher than average or your optic nerve looks unusual, your doctor might use a pachymeter, which uses sound waves to measure the thickness of your cornea. The most common way of measuring corneal thickness is to put an anesthetic drop in your eye, then place a small probe in contact with the front surface of the eye. The measurement takes seconds.

You might need more-specialized tests, depending on your age, medical history and risk of developing eye disease.

Results from an eye exam include:

Whether you need vision correction, either through glasses, contact lenses or surgery
Whether your eyes are healthy, or you have cataracts, glaucoma or retinal disorders, such as macular degeneration or diabetic retinopathy
If you need corrective lenses, your doctor will give you a prescription. If your eye exam yields other abnormal results, your doctor will discuss with you the next steps for further testing or for treating an underlying condition.
