Eye Center of Texas First in Texas to Offer Epioxa™ Cross-Linking for Keratoconus
Eye Center of Texas is proud to announce that Yasir Ahmed, M.D., is the first physician in Texas to offer Epioxa™ HD / Epioxa™, an FDA-approved, next-generation corneal cross-linking treatment for keratoconus. The treatment is now available at the practice’s Bellaire location, making Eye Center of Texas among the first in the United States to bring this advanced therapy to patients.
What is keratoconus?
Keratoconus is a progressive eye condition that causes the cornea to thin and bulge into a cone-like shape. This change can lead to blurred or distorted vision that worsens over time.
The condition often begins in adolescence and progresses through early adulthood. While it may not always be widely recognized, keratoconus can have a significant impact on vision and quality of life. If left untreated, some patients may eventually require a corneal transplant.
A new approach to treatment
Traditionally, keratoconus has been managed with glasses or contact lenses to improve vision. However, newer treatments like corneal cross-linking are designed to address the underlying cause of the condition by strengthening the cornea and slowing or stopping its progression.
Epioxa represents a meaningful advancement in this approach.
Unlike earlier cross-linking procedures, Epioxa uses an “epi-on” technique, which keeps the cornea’s outer layer intact during treatment. This allows for:
- Improved patient comfort
- Reduced disruption to the eye’s surface
- Faster recovery time
- A streamlined treatment experience
Why Epioxa stands out
Epioxa is the first and only FDA-approved epithelium-on, oxygen-enriched corneal cross-linking therapy for keratoconus. It is designed to deliver treatment through the cornea’s surface without removing its protective outer layer.
Clinical studies have shown that Epioxa can help stabilize the cornea and halt progression of the disease, with particularly strong results seen in younger patients.
Bringing advanced care to Texas
Dr. Ahmed, a fellowship-trained cornea specialist, has extensive experience in advanced surgical techniques and is committed to expanding access to innovative treatments. By introducing Epioxa to Texas, he continues Eye Center of Texas’ mission to provide patients with leading-edge care close to home.
Eye Center of Texas remains dedicated to offering the latest advancements in vision care and helping patients maintain long-term eye health and quality of life.

Fast-Growing Cataracts and How to Fight Them
Most cataracts develop slowly over time, but not all of them. Terms like “aggressive cataracts,” “fast-growing cataracts,” and “fast-developing cataracts” can catch patients off guard if they’ve only heard that cataracts are a gradual condition.
It’s true that most cataracts develop more slowly, making them easier to diagnose and treat before they become too harmful. Can cataracts progress rapidly? Yes. Certain conditions and activities do increase the likelihood of developing fast-growing cataracts, but treatment options are available, including blade-free laser cataract surgery.
Aggressive cataracts can disrupt your day-to-day life, but they aren’t an insurmountable obstacle. Your vision can be restored with the help of Eye Center of Texas.
What Is the Difference Between Slow- and Fast-Growing Cataracts?
There are three common types of cataracts named for their location in relation to the eyes’ lenses. Nuclear cataracts (also referred to as nuclear sclerotic cataracts) and cortical cataracts are the slower-moving conditions that people tend to think of when they think of cataracts. Both types of cataracts can become more problematic with age if left untreated.

Nuclear cataracts develop in the nucleus or the center of the lens. By contrast, cortical cataracts occur on the outside — the cortex — of the lens.
The third common type of cataract, posterior subcapsular cataracts, occurs in the backmost layer of the cortex beneath the lens capsule. Unlike nuclear cataracts and cortical cataracts, this condition appears more frequently in younger people and tends to develop much faster.
What Causes Fast-Growing Cataracts?
Certain conditions and environments can facilitate cataract development and create their own incidents of aggressive, fast-growing cataracts. While less common than the three major types of cataracts, they can still be incredibly problematic and may require surgical intervention to correct.
Some causes of fast-growing cataracts include, but are not limited to, the following:
- Diabetes: Also called “diabetic snowflakes” because of their shape and gray-and-white opacity, diabetes-related cataracts occur when an enzyme converts too much glucose into sorbitol, which affects lens clarity.
- Trauma: Trauma-related cataracts occur as a result of your eye enduring either blunt or penetrating trauma that disrupts your lens fibers. These types of cataracts are typically the fastest-growing variety a patient may experience.
- Radiation: Radiation-related cataracts, sometimes listed under trauma-related cataracts, occur after the lens has been exposed to radiation. Exposure to high levels of radiation can result in clouded vision in as little as two years. Exposure to lower levels of radiation can take over a decade to affect vision, making it one of the slower-moving cataracts on this list.
- Congenital: Congenital cataracts are present at birth, and may or may not move fast based on the child’s genetics. Milder examples of this cataract type can correct themselves over time, especially if they don’t impede vision.
Any type of cataract, fast-growing or age-related, tends to progress more quickly in people who smoke or regularly use corticosteroids.
How Are Fast-Growing Cataracts Treated?
Patients diagnosed with fast-growing cataracts almost always want to know how to slow their growth. Cataracts can be treated to restore vision, especially if caught early.
Laser cataract surgery, blade-free cataract surgery, and iStent surgery are all available options. The right path forward depends on several factors, including:
Your doctor will be able to tell you the correct path forward based on a few different factors, including (but not limited to) the following:
- Age
- Overall physical health
- Overall eye health
- Progression of your cataracts
- Source of your cataracts
- Any medications you may be taking
iStent surgery, it should be noted, often works best for instances of cataracts in patients who also deal with glaucoma.
Is Cataract Surgery Safe?
One of the most common concerns patients have is the safety of cataract surgery.

Whether you need a procedure for slow- or fast-growing cataracts, nuclear cataracts, cortical cataracts, or another condition, your options are safe, scientifically backed, and performed to full ophthalmological industry standards.
Every surgery still comes with side effects and risks, even the safest procedures available. Your surgeon will be able to give you details about all the ins and outs of the different options you may need to consider when getting your cataracts treated. Fortunately, all cataract surgeries are generally considered low-risk for the majority of patients.
How Much Does Cataract Surgery Cost?
Most private insurance companies, as well as Medicare, cover the majority of expenses associated with these procedures.
We don’t believe that cost should be a barrier to receiving quality eye care. Before you commit to a surgical procedure with us, please review our financing options available as well as our accepted insurance list.
Can Fast-Growing Cataracts Be Prevented?
While preventing cataracts altogether isn’t possible, there are a few risk factors that may make you more likely to develop cataracts earlier in life, such as:
- People over the age of 40
- People who live in high altitudes
- People with a family history of cataracts
- People who have been exposed to large amounts of radiation, including UV light from the sun
- People with high blood pressure
- People with a history of eye injury
- People who take steroids, regardless of whether or not the medication has been prescribed
- People with obesity
- Diabetics
- Smokers
Scheduling regular eye exams and discussing your personal risk factors with your doctor is the most effective proactive step you can take.
Even if you end up developing slow- or fast-growing cataracts, taking the precautionary steps can still help with reducing the severity of your symptoms.

What Are the Most Common Problems After Cataract Surgery?
Cataract surgery is one of the most commonly performed and highly effective procedures for restoring vision in patients affected by the clouding of the eye’s natural lens.
While the vast majority of patients experience no complications and see a significant improvement in their eyesight, some side effects can occur during the healing process.
The most common problems after cataract surgery include:
- Mild discomfort and itching
- Cloudiness and/or blurry vision
- Light sensitivity
- Specks or floaters in vision
- Swelling
- Eye infection
Keep reading for insight from the cataract surgeons from Eye Center of Texas into what patients might expect following cataract surgery in Houston and advice on managing these side effects effectively.
Want to learn more about cataracts?
1. Mild Discomfort and Itching After Cataract Surgery
Mild discomfort and itching are among the most common and immediately noticeable problems after cataract surgery, because it is natural for the eye to feel slightly irritated while it heals. Patients are strongly advised against rubbing or pressing on their eye, as this can exacerbate the irritation and potentially lead to complications.
To manage these symptoms, your surgeon may recommend over-the-counter pain relievers and prescribe eye drops to reduce inflammation and prevent infection. Typically, these discomforts diminish significantly within a few days post-operation, but it’s crucial to follow your surgeon’s care instructions closely and report any severe or lasting symptoms immediately.
2. Cloudiness and/or Blurry Vision After Cataract Surgery
Cloudiness or blurry vision after cataract surgery is a common concern, but in many cases, it is not a side effect of the surgery itself. It often reflects the eye adjusting to its new intraocular lens (IOL) or mild swelling of the cornea in the days following the procedure.
Most patients state that their vision becomes less cloudy only 48 hours post-op, but keep in mind, if you have floaters, they may be more visible now that you are seeing through a clear lens.
Typically, patients who opt for Monofocal IOLs (the standard IOL that’s covered by most insurances) can expect a slightly longer time before adjusting to their new vision. This is because Monofocal lenses only correct nearsightedness or farsightedness, but not both.
Patients typically opt to correct for nearsightedness (for seeing far away objects) and then rely on glasses to help them see objects that are close-at-hand.
3. Sensitivity to Light After Cataract Surgery
Light sensitivity, clinically referred to as photophobia, is a common symptom during cataract surgery recovery.

This condition, known as photophobia, usually dissipates a few days following the procedure as the eye heals. During this time, the pupil is adjusting to the new intraocular lens and the increased clarity of vision, which can lead to an increased sensitivity to bright lights or glare.
Wearing sunglasses when outdoors and avoiding harsh indoor lighting can help manage this sensitivity effectively. It’s also beneficial to use artificial tears if the eyes feel dry or irritated, as this can sometimes exacerbate sensitivity to light.
Over time, as the eye adapts to the IOL and recovers from surgery, light sensitivity should markedly decrease. However, if severe light sensitivity persists, it’s essential to consult with your surgeon, as it may indicate underlying issues that need attention.
4. Specks or Floaters in Vision After Cataract Surgery
Seeing specks or floaters in your vision after cataract surgery can be alarming, but it’s often not a cause for concern. These small, dark shapes or lines may appear to drift across your field of vision and are commonly caused by tiny bits of protein or debris trapped in the vitreous, the gel-like substance that fills the eye.
After cataract surgery, these particles can become more noticeable as they move around inside the eye due to changes in pressure during the procedure. In most cases, these floaters will eventually settle and become less bothersome.
However, a sudden increase in the number of floaters, especially when accompanied by flashes of light or a shadow across the vision, should be evaluated promptly. These symptoms can occasionally signal inflammation or a retinal issue that requires attention.
5. Swelling After Cataract Surgery
Swelling of the eye area is a common reaction following cataract surgery, typically manifesting as puffiness around the eyelids or within the eye itself. This occurs as the body’s response to the surgical intervention and the healing process that follows.
To alleviate swelling, patients are advised to use cold compresses gently applied to the affected area and to keep their head elevated, especially during sleep, to reduce fluid accumulation. Additionally, your surgeon may prescribe anti-inflammatory medication or eye drops to help manage swelling and discomfort. Usually, the swelling diminishes significantly within the first few days post-surgery, but in some cases, it may take a couple of weeks to fully resolve.
Like most side effects after cataract surgery, continuous monitoring of the swelling is crucial; if it worsens or is accompanied by severe pain or vision changes, immediate medical attention should be sought, as it could indicate complications requiring prompt treatment.
6. Eye Infection After Cataract Surgery

While infections following cataract surgery are rare, they represent a serious potential complication. The primary concern is endophthalmitis, an inflammation of the eye’s interior caused by infection, which can lead to significant vision loss if not treated promptly and effectively.
Symptoms of an eye infection can include severe pain, redness, blurred vision, and discharge from the eye. To minimize the risk of infection, patients must adhere to post-operative care instructions meticulously, such as using prescribed antibiotic eye drops, avoiding rubbing or touching the eye, and keeping water away from the eye during the initial healing period.
If any of these symptoms appear, contact your surgeon the same day. Infections can escalate quickly, and early treatment is the most effective way to protect your vision.
What to Expect During Cataract Surgery Recovery
The recovery timeline for cataract surgery and laser cataract surgery procedures varies from patient to patient, but typically patients start to notice an improvement in their vision within a few days after the procedure. However, it’s important to note that complete healing can take up to 3-6 weeks.
During the initial weeks of recovery, patients may experience fluctuations in their vision or mild discomfort, which gradually subsides over time. Outside of initial blurriness and dry eyes, side effects and problems after cataract surgery are infrequent and rarely threatening.
First 24 to 48 Hours Post-Surgery
During the first day or two after surgery, it’s common for patients to have blurry vision as the eye starts to heal and adjust. It’s essential during this period to rest the eyes and avoid any strenuous activities or heavy lifting, which could strain the eyes and impact the healing process.
First Week Post-Surgery
Most patients find that their vision significantly improves within the first week after surgery. It’s crucial to continue following the post-operative care instructions provided by the ophthalmologist, including using the prescribed eye drops to prevent infection and reduce inflammation.
Six Weeks Post-Surgery

By the six-week mark, most patients have fully recovered from cataract surgery and have stable vision. Throughout the recovery period, even after your vision has stabilized, wearing sunglasses to protect your eyes from bright lights and UV rays is recommended, at least until you’ve had a chance to follow up with your ophthalmologist.
A follow-up appointment with your ophthalmologist at this stage confirms that the eye is healing correctly and helps determine whether any additional treatment or updated glasses prescription is needed. It’s important to have a follow-up appointment with your ophthalmologist to ensure the eye is healing correctly and to assess if any further treatment is needed.
