If you have a cataract, it has little effect on your vision at first. It’s just blurry and seems like a dirty camera lens which is cloudy. As it progresses, the light seems too bright or glaring than before whether it’s sunlight or car headlights when you’re driving at night.
There are different types of cataracts that’s why it’s important to have your eyes checked to identify the factors that cause the development and the prescribed solution that you need. To further check whether you have a cataract, your medical history will be reviewed along with the list of signs and symptoms you jotted down during an eye examination. Here are several tests conducted before cataract surgery in Los Angeles as advised by your surgeon:
-
Visual acuity test
This is a common type of eye exam performed by eye care professionals. They use an eye chart to measure how well you can read a series of letters or symbols at a certain distance. Your eyes will be tested one at a time while covering the other eye. This test refers to your ability to discern the details of the things you see. It allows the eye doctor to determine if you have a normal vision, which is 20/20; it all depends on the result of this test.
-
Slit-lamp examination
Another common type of exam is also called biomicroscopy. It identifies any abnormality or problem that persists by checking the structures of your eye under magnification. You will be asked to rest your chin and forehead on the instrument, which is called a sit lamp, it’s a microscope that uses high-intensity light. Eye drops may be given to make any abnormalities on the surface of your cornea more visible, allowing your pupil to dilate. As they look closely at your eyes, it captures different views allowing the eye doctor to check all areas such as the eyelids, conjunctiva, iris, lens, sclera, cornea, retina, and optic nerve.
-
Retinal exam
It’s sometimes called ophthalmoscopy or funduscopy. It evaluates the back of your eye, the optic disk, including the retina and underlying layer of blood vessels. Eye drops will be given to make your pupils dilated. In this way, your eye doctor can examine your lens for any signs of cataracts.
