Dry Eye Disease

Dry eye disease is an exceedingly common condition when your eyes aren’t getting enough hydration from your tears.

Diabetic Eye Care

Diabetes is a disease that can affect the entire body, but it’s infamous for having significant effects on your eyes. That’s why, if you have or are at risk for diabetes, it’s important to have an eye doctor look for related conditions like diabetic retinopathy.


Glaucoma is one of the leading causes of blindness worldwide, and due to its tendency to cause vision loss without warning, it’s been dubbed the “silent thief of sight.”

Ocular Disease

Pre- and Post-Surgical [Perioperative] Care

Open Letter to Patients

Hello! And welcome to Alliance Vision Institute. Where we are populated by doctors and staff who are passionate about making your vision our priority.
Through my time in school and training, I’ve been privileged to see how healthcare, and specifically eye care, changes people’s lives. All of my family members, from my immediate nuclear family to my lovely extended family, which includes my most beloved grandmother, require vision correction in all of their forms; glasses, contacts, and refractive procedures. So it’s safe to say, it has been long instilled in me to care and become aware of the visual needs of those around me. And it has been ingrained in me, still, to care about those who require aid in achieving their vision goals.
My philosophy of care is embodied in my belief that education is a right for all. I want to ensure that every patient is involved and included in each step of their eye care, especially as it pertains to their overall health and well-being. So, please, feel free to ask questions or interrupt me if I am expounding upon things that you are not interested in hearing! My joy comes when my investment in the health of my patient’s eyes is reciprocated by the patients themselves.
In my practicing here at AVI, I want to embody that health is wealth, and our eyes are the grand prize.
It is our honor that you’ve entrusted us to be the experts that get to gaze upon your eyes and their needs.

Q&A With Dr. Cha

What made you decide to become an optometrist?
I took a high school internship at a family optometrist’s office, which was my first ever time stepping foot into an eye doctor’s office as I had never needed to have my vision corrected. This was my first venture in exploring budding aspirations of entering the healthcare field. When the doctor let me look at my first ever set of eyes through the microscope, I will never forget. It was a post-LASIK patient with eyes as blue as the ocean. It looked as if wisps of energy constituted her iris and it was the most beautiful thing I had ever seen. I thought, “If I can look at this every day of my life, I think I’d be happy.” And the rest is history.
What is the most satisfying part of your job?
I love seeing my patients curious about their vision care, and I especially love when they light up learning about their eyes. I feel fulfilled when my care brings about noted improvement both in their quality of health and quality of vision.
What differentiates Alliance Vision Institute from other practices?
AVI truly prioritizes optimal, leading-edge eye care for all of their patients. I’ve had the privilege of working at more than a dozen practices in my training and career so far, and I can say that AVI truly embodies the ideals of modern eye care. I’m proud that I can make it my home.
