Cataracts: Your Evaluation
An evaluation will help your eye doctor learn more about vision problems you're having and whether cataracts are the cause. This evaluation includes a medical history, vision tests, and an eye exam. What the doctor learns will help him or her determine the best treatment options for you.
You will be asked questions about your vision and any other eye problems you may have. Your eye doctor will also ask about health problems, such as diabetes. Be sure to mention if you are taking any medications, supplements, or herbal remedies.
Your eye doctor will perform several tests to check your vision. This includes using an eye chart, and testing your vision under different lighting. If you wear eyeglasses or contact lenses, bring them to the exam. This lets your eye doctor check the prescription.
An Eye Exam
During an eye exam, the doctor uses a slit lamp and an ophthalmoscope to look inside your eye. In most cases, eyedrops are used to dilate (widen) your pupils before the exam.
Discussing Treatment Options
After an eye exam, you and your eye doctor will discuss treatment options. A new eyeglass or contact lens prescription may improve your vision for a while. But surgery is the only way to remove a cataract and replace your cloudy lens. If your cataract isn’t keeping you from daily activities, you may wait to have it removed. Together you and your eye doctor will decide what’s best for you.
Measuring the Eye
If you decide to have cataract surgery, the length and front curvature of your eyeball will be measured. This information helps your doctor choose a new lens to replace your cloudy lens. Measurement is done with special tools that may include an A-Scan, laser inferometry, or a keratometer.
