Other San Antonio Ophthalmology Services

Diabetic Eye Care

Diabetes is a disease that affects the body’s small blood vessels, and the eye is the only organ where these vessels can be seen and examined without invasive testing methods. Because the eye’s blood vessels can help determine the condition of the blood vessels in the rest of the body, patients with diabetes may be instructed by their primary care doctor to schedule annual eye examinations. Routine eye exams can not only help manage diabetes, they also help determine whether the eye has been affected by diabetes, which can lead to bleeding and swelling of the retina, vision loss, and even complete blindness. At San Antonio Eye Specialists, we use only the latest technology for our eye examinations. The Eidon fundus camera, with enhanced visualization capabilities, helps diagnose and manage diabetic eye disease. We also use the Cirrus OCT (Optical Coherence Tomography), which uses near-infrared frequency light to reveal a high resolution cross-section of the retinal layers. This helps detect and localize early lesions, which helps us recommend a treatment plan, such as laser retinal therapy or surgical intervention, to stop the progression of advanced diabetic eye disease.

Eye Allergy Treatment

San Antonio is known for having a variety of allergens throughout the year. Cedar and oak are common in the winter, while pollen, ragweed, and certain flowers are popular in the springtime. Our immune system is triggered by allergens like these, as well as mold, pollen, and even pet dander. The result is red, watery, itchy eyes that require prescribed medication to control eye allergies. If you believe you may have eye allergies, schedule a consultation with us to be diagnosed for the appropriate care.

Pterygium Surgery

Pterygium is a condition in which an abnormal, non-cancerous, “fleshy” growth of the eye occurs. A pterygium typically begins in the sclera (the white part of the eye) near the nose and begins growing slowly towards the cornea (the clear part of the eye). When this occurs, it typically causes redness and irritation. In severe cases, it may even obscure the vision by growing over the iris (colored part of the eye). When the pterygium affects the patient’s vision, surgical intervention may be covered by insurance.

Pterygium removal has advanced greatly over the decade. Modern techniques make pterygium surgery safer, more effective, and more comfortable for the patient with a lower risk of recurrence. Pterygium surgery is an outpatient procedure that leaves the patient’s eye clear and less irritated. The process of removing a pterygium involves the use of an amniotic membrane, fibrin tissue adhesive, and a conjunctival autograft. This surgical technique is designed to lessen inflammation to the underlying Tenon’s fascia from which pterygium growth is postulated (although not proven) to emerge. Implementing these three surgical steps lowers recurrence of pterygium to less than 1%. If you have a pterygium, contact San Antonio Eye Specialists to learn more about your removal options.

Tecnis Symfony® Lens

The Tecnis Symfony® Lens features a multifocal lens design, with multiple power rings, to help patients see at various distances. The Symfony® Lens is also designed to improve night vision by significantly reducing glare and halos. Like other multifocal IOLs, the Tecnis Symfony® allows for better vision across a broad range of distances and can reduce or eliminate a patient’s need for glasses or contact after cataract surgery.

Routine Examinations for Patients on Certain Medications

Certain medications, such as Plaquenil or Gilenya, can have adverse effects on vision. If you take these medications, it is important to let your ophthalmologist know, and schedule annual exams to monitor changes within the eye.


Plaquenil, or Hydroxychloroquine, is a medication used to treat conditions such as Rheumatoid Arthritis, Lupus Sarcoidosis, and other autoimmune disorders. Plaquenil has been shown to cause retinopathy, or damage to the retina. At San Antonio Eye Specialists, we monitor patients on Plaquenil by testing visual acuity, color vision, central vision field testing, distortion testing, and conducting a thorough retina exam. If signs of retinopathy are detected, we may recommend you stop taking the drug so vision can return to normal. In some cases, vision may be permanently affected.


Gilenya, or Fingolimod, is a medication used to help treat symptoms of multiple sclerosis, or MS. Patients who take Gilenya may develop macular edema, a condition in which the fluid in the back of the eye swells and causes blurry vision. Symptoms appear 3 to 6 months after patients begin taking Gilenya and typically disappear once the drug is discontinued. Before taking Gilenya, patients should have a dilated eye exam. Three months after starting treatment, patients should have an OCT (Optical Coherence Tomography) to determine whether Gilenya is affecting their eyes. To schedule an exam before or during your Gilenya treatment, contact San Antonio Eye Specialists.

Frequently Asked Questions About Ophthalmology

What’s the difference between an ophthalmologist and an optometrist?

arrow icon

Ophthalmologists and optometrists are both eye specialists primarily differing in years of education and training. At San Antonio Eye Specialists, both specialties diagnose, manage,  and treat different eye conditions. San Antonio Eye Specialists is a comprehensive ophthalmology clinic specializing in refractive procedures.  We treat various eye conditions like glaucoma, cataracts, dry eye, and other visual concerns that affect the overall health of the eye. In Texas, only Ophthalmologists perform various eye surgeries, from the treatment of different eye conditions to corrective vision surgery like LASIK. 

Optometrists, on the other hand,  focus on the corrective side of eye health without surgery. Optometrists help their patients by prescribing glasses or contacts, or by updating existing prescriptions. 

You can learn more about the difference between an ophthalmologist and an optometrist in the San Antonio Eye Specialists blog

What kinds of procedures do ophthalmologists perform?

arrow icon

At San Antonio Eye Specialists, we are a comprehensive ophthalmology practice specializing in refractive procedures; the art of correcting vision (myopia, hyperopia, and astigmatism) without the aid of glasses or contact lenses.  Our ophthalmologists perform LASIK, PRK, ICL, RLE (Refractive Lens Exchange), LAL (Light Adjustable Lens), and laser-assisted cataract surgery.  When glaucoma needs to be managed beyond medication or laser treatment, then we offer iStent surgical options.  We also treat droopy, saggy eyelids with blepharoplasty, also known as Eyelid Rejuvenation.

What are some signs that I may need to visit an ophthalmologist?

arrow icon

Some of the symptoms that may be an indicator that you need to visit an ophthalmologist urgently include: 

• Noticeable pressure behind the eyes
• Bulging eyes
• Dark areas or “curtains” that impair vision
• Sudden decreased or impaired vision
• Double vision 
• Excessively watery eyes or tearing 
• Excessive or sudden “floaters” or spots within the eyes, as well as flashes of light
• Halos, or colored circles around light sources
• Eye injury
• Eye pain

The eyes are the windows to our overall health.  Often we detect problems such as the early onset of diabetes or high blood pressure by examining the blood vessels in the back of the eye.  In general, keeping up with annual eye exams, especially once you reach age 40 is important to detect any early warning signs and keep up with preventative eye care.
