How Dr. Feng can help

A few of the most common reasons Bay Area patients come in.

Cloudy, blurry, or glare-affected vision

Often a sign of cataracts — Dr. Feng will review all of the lens options and help you choose the best lens based on your lifestyle.

Swelling of the cornea

Dr. Feng will evaluate and discuss the right treatment for you, ranging from conservative approaches such as eye drops to surgical approaches including partial or full-thickness corneal transplants.

Keratoconus

A progressive condition that often starts in the teens. Corneal cross-linking can stop progression early, before vision loss becomes harder to treat.

Pterygium

A growth on the surface of the eye that is often due to sun exposure.

Comprehensive eye exam

Dr. Feng can perform a thorough eye check to assess your eye health and look for signs of dry eyes, diabetes, or glaucoma.

A corneal infection

Prompt evaluation for infections that present as redness, tearing, and pain in the eye. Often related to contact-lens use.

Does Dr. Feng speak Mandarin?

Yes — she's fluent in conversational Mandarin and happy to discuss your care in Mandarin if that's more comfortable.
