Blurry vision, eye pain, or new symptoms can be alarming. But one of the first questions patients ask is: “Do I need to see an optometrist or an ophthalmologist?”
It’s a good question and an important one.
Seeing the wrong provider can delay treatment or cost you time and money.
Fortunately, if you live in San Antonio or the surrounding South Texas region, there’s one place where both specialties work together to make sure your eyes get the right level of care: Eye Associates of South Texas.
With 10 locations across the region and both optometrists and ophthalmologists on staff, our team helps patients quickly determine where to start, what to expect, and how to protect their vision.
Whether it’s a simple exam or something more serious.
Here’s how to know which type of eye doctor you need and when to make the call.
Understanding the Difference Between an Optometrist and an Ophthalmologist
Many people assume all eye doctors do the same thing. But there’s an important distinction between optometrists and ophthalmologists, especially when it comes to diagnosis, treatment, and surgery.
At Eye Associates of South Texas, we offer both specialties at all locations so patients can get exactly the care they need, without second-guessing.
What Does an Optometrist Do?
An optometrist is a licensed Doctor of Optometry (OD), trained to:
- Perform comprehensive eye exams
- Diagnose and manage vision problems
- Prescribe eyeglasses and contact lenses
- Treat common conditions like dry eye, pink eye, or eye strain
- Monitor chronic diseases (like diabetic eye disease) and refer to specialists when needed
Most people see an optometrist for routine eye care. But many don’t realize just how important those visits are.
According to a 2023 report from the Centers for Disease Control and Prevention (CDC), 93 million adults in the U.S. are at risk for serious vision loss, but only about half visit an eye doctor each year.
Regular exams with an optometrist can detect early signs of conditions that could otherwise lead to permanent vision damage.
What Does an Ophthalmologist Do?
An ophthalmologist is a medical doctor (MD or DO) trained to:
- Treat complex eye conditions with medication and surgery
- Perform surgeries like cataract removal, LASIK, retinal procedures, and glaucoma treatments
- Manage diseases like macular degeneration, diabetic retinopathy, and advanced glaucoma
- Handle eye trauma, tumors, and systemic disease-related vision issues
Ophthalmologists can perform everything an optometrist can. But they’re usually called in for surgical or medically intensive cases. Most patients are referred to them after an initial exam or diagnosis by an optometrist.
Comprehensive, In-House Care Across South Texas
One of the biggest advantages of choosing Eye Associates of South Texas is that you don’t have to decide between seeing an optometrist or an ophthalmologist. We have both under one roof, across San Antonio, New Braunfels, Seguin, Castroville, San Marcos, Hondo, Gonzales, and La Vernia.
Whether you need a quick glasses update or long-term management for glaucoma or cataracts, our team will guide you to the right specialist, without bouncing between multiple practices.
Common Reasons to See an Optometrist
Not every eye issue requires a surgeon. In fact, many of the most common eye problems can be handled by a licensed optometrist, often on the same day. Optometrists are the first line of defense for protecting your vision and managing long-term eye health.
Blurry Vision or Prescription Changes
If your vision has started to blur when reading, driving, or using screens, an optometrist can:
- Evaluate your current prescription
- Test for early signs of presbyopia (age-related near vision loss)
- Rule out refractive changes related to conditions like diabetes
Adults over 40 often need more frequent vision checks, even if they’ve never worn glasses before.
Dry Eye Syndrome
Dry eye is one of the most common complaints among South Texas adults, especially in regions like San Antonio, Seguin, and New Braunfels, where hot, arid conditions and year-round allergens can lead to chronic dryness.
According to the American Academy of Ophthalmology (2023), nearly 16 million U.S. adults have been diagnosed with dry eye, but the actual number could be twice as high due to underreporting.
Optometrists offer targeted treatments, including:
- Prescription eye drops
- Lifestyle and screen-use adjustments
- In-office procedures for tear production and retention
Digital Eye Strain
Younger adults aren’t exempt from vision problems. A 2023 study by The Vision Council found that 68% of adults under 50 report symptoms of digital eye strain, including headaches, eye fatigue, and blurred vision.
An optometrist can help with:
- Specialized blue-light filtering lenses
- Screen-time recommendations
- Adjustments to work habits and lighting
Eye Allergies, Irritation, or Mild Infections
Red, itchy, or watery eyes are often caused by:
- Seasonal allergens
- Environmental irritants (dust, wind, mold)
- Mild bacterial or viral infections (pink eye)
An optometrist can diagnose and treat most of these conditions on the spot, helping you avoid unnecessary ER or urgent care visits.
Preventive Care for Adults Over 40
Even if your vision seems fine, annual visits with an optometrist can detect early signs of:
- Glaucoma
- Cataracts
- Macular degeneration
- Diabetic retinopathy
When caught early, these conditions are far more manageable, often before symptoms ever appear.
When to See an Ophthalmologist Instead
While optometrists manage many routine eye problems, certain conditions require the expertise of a board-certified ophthalmologist, a medical doctor who specializes in the diagnosis, treatment, and surgical care of eye diseases.
If you’re experiencing any of the following symptoms or have been diagnosed with certain eye conditions, it’s time to see an ophthalmologist.
Sudden Vision Changes or Eye Trauma
If you notice:
- Sudden vision loss
- Flashes of light
- A sudden increase in floaters
- Eye pain or injury
These may be signs of a retinal detachment, eye bleed, or infection that requires immediate medical attention. Do not wait for a routine appointment. Call or visit an ophthalmologist promptly.
Cataracts
Cataracts affect more than 24 million Americans over age 40, and the number is growing
(Prevent Blindness, 2023).
While early signs can be monitored by an optometrist, only an ophthalmologist can:
- Confirm the diagnosis
- Discuss your lens replacement options
- Perform cataract surgery with precision and customization
Eye Associates of South Texas performs cataract evaluations and surgeries in multiple locations, including San Antonio, New Braunfels, and Seguin.
Glaucoma and High Eye Pressure
Glaucoma is called the “silent thief of sight” because it often progresses without noticeable symptoms until it’s advanced.
An ophthalmologist:
- Confirms diagnosis with optic nerve imaging
- Prescribes medicated eye drops or laser treatments
- Performs surgeries to relieve eye pressure if needed
Ongoing glaucoma management often involves co-managed care between optometrists and ophthalmologists; Eye Associates facilitates seamlessly under one roof.
Macular Degeneration and Diabetic Eye Disease
Patients with:
- Age-related macular degeneration (AMD)
- Diabetic retinopathy
- Hypertensive retinopathy
…require the specialized care of an ophthalmologist to prevent long-term vision loss. Treatments may include:
- Intravitreal injections
- Retinal imaging and monitoring
- Laser therapy or surgery
South Texas has higher-than-average rates of diabetes and hypertension, making early eye screening and medical intervention especially important.
Surgical Eye Care (Beyond Cataracts)
Only an ophthalmologist can perform procedures like:
- LASIK and refractive surgery
- Glaucoma laser procedures
- Corneal transplants
- Retinal repairs
- Oculoplastic surgery for droopy eyelids or tear duct issues
Eye Associates of South Texas provides comprehensive surgical consultations at their San Antonio and regional locations, helping patients get the care they need without leaving their community.
