Specialty care · Dry Eye Clinic

Dry eye isn’t something you have to live with.

We treat burning, gritty, watery, or tired eyes.

  1. 01

    Find the cause

    Imaging and tear-film measurement show what’s involved: oil glands, inflammation, or the eye surface.

  2. 02

    Treat it directly

    Therapy and prescription care treat the source, not just the symptoms.

  3. 03

    Measure the progress

    Follow-up measurements confirm the treatment is working.

Advanced diagnostics

Many conditions begin quietly.

Diagnostic imaging lets your doctor examine the retina, measure precisely, and compare results.

See the diagnostics

Layer-by-layer retinal detail

Cross-sectional imaging supports evaluation of macular changes and glaucoma risk.

A photo record of the retina

Retinal photographs document what the back of your eye looks like today.

How your vision actually functions

Diopsys visual electrophysiology adds functional context when symptoms and findings don’t match.

Change tracked over years

We compare against your record, so change is easier to see.

Kindness is the standard we hold ourselves to, for everyone, on every visit.

I've been coming here for years. I have developed great relationships with some of the staff that has been here for years. Also, new staff members have been really helpful. I recommend this office to everyone I know.

I am glad I found this place. … As soon as I walked in I noticed how busy it was, but the receptionist acknowledged me right away. … My glasses took about a week to be ready, which was great! You have gained a long-time patient!
