What are Cataracts?

Featured Image

For most people, cataracts are an unavoidable part of the aging process. If not treated correctly, cataracts can cause reduced vision, and over time, complete blindness. Dr. Wang and Dr. Frenkel provide education and resources to help patients with cataracts in the greater Nashville area.


The first symptoms of cataracts are typically blurry vision or sensitivity to light. If you have trouble seeing at night, while reading, or see a glare, these could also be early symptoms of cataracts. Though cataracts aren’t painful, our team is dedicated to providing you with an evaluation to reduce vision issues.

A cataract is an opacification in the natural lens of the eye. The lens of the eye is about the size and shape of an M&M and sits inside the eye behind the iris. Cataracts are a result of the degradation of proteins that make up the lens. While this process happens to everyone, certain behavioral and medical issues may also cause cataracts. These include but are not limited to smoking, excessive drinking, prolonged exposure to the sun, diabetes mellitus, hypertension and more.

Cataracts usually require cataract surgery for removal and visual restoration. Our doctors will conduct a contrast sensitivity test to see if the patient is able to see a difference in images. 

After the initial tests, the patient will undergo a slit-lamp exam which is where an ophthalmologist uses a microscope that shines a narrow “slit” of light into the eye to check its outermost structures. If cataracts are found, a potential acuity exam may be performed to see if the patient needs surgery.


Potential options for cataracts treatment are dependent on the stage of the disease. Wang Vision performed the first laser-assisted cataract surgery in the state of Tennessee. We utilize four state-of-the-art technologies to assist patients with cataracts and are committed to finding the best treatment options for you. If you develop cloudy vision in the months following cataract removal surgery, YAG Laser Capsulotomy can be performed for better vision. 

Patients can learn about advanced cataract treatment options by scheduling a consultation with Wang Vision Institute today. Attend our FREE Online Vision Seminars every Tuesday at 7 p.m. CST to receive more information.
