Pterygium Eye

(SURFER’S EYE) in Los Angeles

Pterygium causes and risk factors

The exact cause of pterygium is unclear, but it is more common in populations living near the equator with prolonged exposure to sunlight and UV radiation. This condition is sometimes called surfer’s eye because it is common among surfers.

Risk factors for pterygium include:

• Exposure to ultraviolet light (from the sun or other sources)

• Living in sunny climates near the equator

• Living in dry, dusty climates

• Spending a lot of time outdoors (working outdoors increases your risk by 150%)

• Complications from dry eye disease

• Being male, as men are diagnosed with pterygium at significantly higher rates than women, likely due to greater cumulative sun and wind exposure

• A family history of pterygium, since genetic predisposition can increase your likelihood of developing the condition even with moderate UV exposure

It is also worth understanding what pterygium can do to your vision if left unchecked. As the fleshy tissue advances across the cornea, it can distort the cornea’s natural curvature and induce astigmatism, causing blurred or doubled vision that glasses may only partially correct. This is one of the most compelling reasons to have any suspicious growth evaluated early by a world-class specialist rather than waiting until symptoms become disruptive. At Assil Gaur Eye Institute, our surgeons bring elite precision to every pterygium evaluation, giving you a clear picture of your risk and the most advanced removal options available if treatment becomes necessary.

How to Prevent Pterygium

Now that you understand what drives pterygium growth, the good news is that many of those risk factors are within your control. A few consistent habits can go a long way toward protecting your eyes and reducing your chances of ever needing treatment.

Wear UV-blocking sunglasses every time you go outside. This is the single most important step you can take. Look for wraparound frames that block 100% of both UVA and UVB rays. Wraparound styles offer extra coverage on the sides, where reflected light from sand, water, and pavement can still reach your eyes. If you spend time outdoors and want to understand just how damaging UV exposure can be, our guide to safely protecting your eyes from intense light is a helpful read.

Add a wide-brimmed hat to your routine. Sunglasses alone do a great job, but pairing them with a hat that shades your face gives you an extra layer of protection during peak sun hours.

Use lubricating eye drops regularly. Chronic dryness and irritation from wind, dust, and dry environments accelerate the tissue changes that lead to pterygium. Keeping your eyes well lubricated reduces that ongoing irritation. If dry eye is already a concern for you, screen time can make it significantly worse, so it is worth addressing proactively.

Limit prolonged exposure to dusty or smoky environments when possible, and wear protective eyewear on job sites where airborne particles are common.

Prevention is always the most elegant solution, but if a pterygium has already developed, world-class surgical care is available to remove it with precision and keep recurrence rates below 1%.

How is pterygium diagnosed?

By simple observation. We can make a formal diagnosis following a slit-lamp examination that allows close-up observation of the lesion under magnification. A biopsy is often taken at the time of removal and sent to a pathologist for diagnostic confirmation.

If you have a pterygium, a thorough eye exam should be performed to assess its impact on your vision and rule out less common diagnoses that can cause an eye tumor.

As part of that comprehensive evaluation, our specialists perform visual acuity testing to measure any reduction in sharpness or clarity caused by the growth. We also use corneal topography, an advanced surface-mapping technique that creates a detailed contour map of your cornea, to detect even subtle distortions in curvature that a standard exam might miss. This precision mapping is especially important when a pterygium begins encroaching on the central cornea, where it can induce astigmatism and meaningfully affect your quality of vision.

Our eye specialist will also measure how far the pterygium extends over your cornea. Usually, you will return for follow-up exams every 1 to 2 years to determine the rate of its growth toward your visual axis.

Effective Treatments for Pterygium

Not every pterygium requires immediate intervention. If your growth is small, stable, and not affecting your vision or comfort, watchful waiting is a perfectly reasonable first step. Your provider will monitor the pterygium at regular check-ups to catch any early signs of progression.

When symptoms are mild to moderate, conservative management is usually the starting point. Our eye care team may recommend or prescribe:

• Lubricating eye drops and artificial tears to relieve the gritty, dry sensation that pterygium commonly causes throughout the day.

• Over-the-counter anti-allergy drops to calm redness and itching triggered by environmental irritants like dust, wind, or pollen.

• Prescription steroid eye drops or ointments for short-term use when inflammation, swelling, or significant discomfort needs more targeted relief.

• UV-blocking sunglasses rated for both UVA and UVB protection, worn consistently outdoors to slow the growth and reduce the risk of recurrence.

If conservative care is no longer keeping symptoms under control, or if the pterygium begins to encroach on your cornea and threaten your vision, surgical removal becomes the recommended path forward. At Assil Gaur Eye Institute, our advanced pterygium removal protocol is designed to deliver precision outcomes and a sub-1% recurrence rate, so you can feel confident you are choosing the very best care available in Los Angeles.

Pterygium surgery (pterygium excision)

If conservative treatments aren’t successful in relieving symptoms or the appearance of pterygia makes you self-conscious, surgery may be needed.

Unfortunately, pterygium surgery is not as simple as cutting the growth out of your conjunctiva, as this approach carries an 80 percent risk of the pterygium returning. 97 percent of regrowth occurs in the first year following the surgical removal of a pterygium.

Because of the high recurrence rate associated with simple pterygium extraction, our ophthalmologists sometimes remove a portion of the patient’s conjunctiva from another part of the eye and use it as a graft to fill the gap left by the pterygium.

This approach, known as conjunctival autografting, continues to be used successfully. However, recurrence rates can still be as high as 33 percent. Although the odds are better, they are still not great.

How does AGEI cut pterygium recurrence from 80% to below 1%?

Over the past 12 years, AGEI’s surgeons have adopted many advances in the field, resulting in a pterygium recurrence rate below 1 percent in our practice. These surgical techniques include:

• Carefully removing the pterygium and underlying scar tissue to achieve clean borders

• Minimizing the surgical manipulation of the tissue surrounding the gap

• Using amniotic membrane graft for its ability to suppress post-op inflammation, scarring, and new blood vessel formation

• Bathing the gap created by the pterygium removal with two powerful medications to minimize post-op inflammation and scarring, which leads to an increased risk of recurrence

• Affixing the graft with fibrin glue to decrease inflammation and irritation at the graft site caused by sutures and to act as a physical barrier along the perimeter of the graft site to thwart pterygium regrowth

• Following a meticulous post-op medication regimen designed to suppress swelling and infection

What to expect after eye whitening surgery

After surgery, your doctor will prescribe steroids and antibiotic eye drops to minimize the chances of recurrence and prevent infection. Compliance with the dosing schedule is key to helping prevent recurrent pterygium.

Your doctor will check you on the day following surgery. Then you will follow up at 1 week, 1 month, 3 months, 6 months, and 1 year post-op. After that, you will be seen annually to check for pterygium recurrence.

You may feel irritation and a foreign body sensation in your eye once your anesthesia wears off. These symptoms will resolve in a week. There will also be redness at the surgical site that can last up to six weeks.

Typically, patients take six to eight weeks to heal fully. Smaller pterygia heal faster than larger ones.

What Happens If a Pterygium Is Left Untreated?

It is tempting to ignore a pterygium, especially when it starts out small and causes only mild irritation. But leaving it untreated can lead to consequences that go well beyond a cosmetic concern, and the longer you wait, the more complicated treatment can become.

In its early stages, a pterygium may simply cause redness, dryness, and a gritty sensation in the eye. Over time, though, the growth can creep steadily across the cornea, the clear dome at the front of your eye. Once it reaches the cornea, it begins to distort the surface, causing a type of irregular astigmatism that blurs and warps your vision in ways that glasses or contact lenses cannot fully correct.

In advanced cases, a pterygium can grow toward the center of the cornea and block your line of sight entirely, leading to significant, permanent vision loss if left unaddressed. The tissue can also cause chronic dry eye symptoms that worsen progressively, making everyday activities genuinely uncomfortable.

There is also a surgical consideration worth knowing. Removing a small, early-stage pterygium is a more straightforward procedure with a faster recovery than removing one that has grown large and deeply embedded in the corneal tissue. Waiting increases both the complexity of surgery and the risk of scarring.

The good news is that with world-class precision and AGEI’s advanced surgical protocol, even more advanced cases can be treated with enviable outcomes. But catching it early gives you the best possible result, so a complimentary evaluation sooner rather than later is always the smarter move.

Should I undergo pterygium removal eye surgery?

With the dramatic improvement in results over the years at our center, most patients now undergo removal at earlier stages for cosmetic reasons rather than due to any visual loss.

Still, the decision to undergo pterygium removal surgery should be made after careful consideration and discussion with your eye doctor and primary health care provider to ensure that you understand the risks and benefits of the procedure and are willing to perform the post-operative eye care regimen necessary for successful results.
