Cataract Examination and Diagnosis

If you notice any changes in your vision, particularly if you are over 40, it is best to consult an eye care professional as soon as you notice the change. This is because there are several eye conditions that have better outcomes if there is early intervention. Cataracts are only one of several eye diseases that can affect us as we age.

What Happens at Your Appointment

You have probably had eye examinations before. There are several different levels of examination, but a complete eye examination that includes dilation can be long. In addition, if you and your doctor decide it is time to schedule cataract surgery, a number of tests and measurements will need to be performed in addition to your complete examination. This can make for a long visit with your doctor, so keep that in mind when you go for your appointment and plan accordingly.

Eye Examination

When you present for your eye examination, your initial evaluation will be performed by a technician. The technician gathers information for your doctor, who will then examine your eyes and determine if additional tests are needed. Be sure to tell the technician what types of symptoms and problems you are having. This will help to make your examination more efficient. A good technician will guide you in this process.

Your eye examination is composed of the following elements:

Visual acuity (what line you can read on the eye chart)

Refraction (your eye glasses prescription)

Intraocular pressure (eye pressure)

Peripheral vision (side vision)

Pupil examination (measures possible neurologic/retinal disease)

Examination of the skin and tissue around the eyes (screening for cancer and lid position abnormalities that can lead to dry eye, exposure and other problems)

Microscopic examination:

Eyelids and lashes

Conjunctiva and sclera

Cornea

Anterior chamber

Iris

Lens capsule

Lens

Vitreous

Optic nerve

Macula

Blood vessels

Peripheral retina

Each part of the examination gives your doctor important information about the health of your eye. This and the symptoms you are having will tell your doctor what additional tests may need to be performed. If your doctor diagnoses you with a cataract, and feels you are a candidate for surgery, you’ll need to have several additional tests. Some of these tests help your doctor determine what power of IOL to place in your eye. Others help your doctor determine whether or not you are a candidate for a premium IOL. There are also some tests that provide your doctor with the information needed to manage your astigmatism if you choose to have it corrected. Remember, each of the steps helps your doctor determine the best way to treat you. All this information contributes to achieving the greatest level of satisfaction for you after surgery.
