About Cataracts
A cataract is a clouding of the lens in the eye that affects vision.
- Most cataracts are related to aging.
- By age 80, more than half of all Americans either have a cataract or have had cataract surgery.
- Cataract surgery is one of the most common operations performed in the United States. Approximately 3 million Americans undergo cataract treatment through cataract surgery every year.
- A cataract can occur in either or both eyes. It cannot spread from one eye to the other.
What causes cataracts?
- The lens lies behind the iris and the pupil. It works much like a camera lens. It focuses light onto the retina at the back of the eye, where an image is recorded. The lens also adjusts the eye’s focus, letting us see things clearly both up close and far away. The lens is made of mostly water and protein. The protein is arranged in a precise way that keeps the lens clear and lets light pass through it.
- As we age, some of the protein may clump together and start to cloud a small area of the lens. This is a cataract.
- Over time the cataract may grow larger and cloud more of the lens, making it harder to see.
- Researchers suspect that there are several causes of cataract, such as smoking and diabetes.
What are the symptoms of a cataract?
- Cloudy or blurry vision.
- Colors seem faded.
- Glare. Headlights, lamps, or sunlight may appear too bright. A halo may appear around lights.
- Poor night vision.
- Double vision or multiple images in one eye.
- Frequent prescription changes in your eyeglasses or contact lenses.
Cataract surgery is a major life-changing event and choosing a surgeon should not be taken lightly. Two of the biggest factors impacting the success of your cataract surgery…is your surgeon’s experience and the technology.

What is Astigmatism?
I just received an email from a friend who wanted to know: what is astigmatism and can it be corrected with LASIK surgery?
Astigmatism is not a disease nor does it mean that you have bad eyes. Astigmatism usually is caused by an irregularly shaped cornea. Instead of the cornea having a symmetrically round shape (like a baseball), it is shaped more like a football.
Astigmatism usually causes vision to be blurred or distorted to some degree at all distances. Symptoms of uncorrected astigmatism are eye strain and headaches, especially after reading or other prolonged visual tasks. Squinting also is a very common symptom.
Yes,LASIK can correct most types of astigmatism. If you’re interested in finding out if LASIK eye surgery can correct your astigmatism, give us a call at 713-395-1515.

Know Your Type of Glaucoma
There are several types of glaucoma. The two main types are open-angle and angle-closure. These are marked by an increase of intraocular pressure (IOP), or pressure inside the eye.
Open-Angle Glaucoma:
This is the most common form of glaucoma, affecting about three million Americans. It happens when the eye’s drainage canals become clogged over time.
The inner eye pressure (also called intraocular pressure or IOP) rises because the correct amount of fluid can’t drain out of the eye. With open-angle glaucoma, the entrances to the drainage canals are clear and should be working correctly. The clogging problem occurs further inside the drainage canals, similar to a clogged pipe below the drain in a sink.
Most people have no symptoms and no early warning signs. If open-angle glaucoma is not diagnosed and treated, it can cause a gradual loss of vision. This type of glaucoma develops slowly and sometimes without noticeable sight loss for many years. It usually responds well to medication, especially if caught early and treated.
Angle-Closure Glaucoma:
This type of glaucoma is also known as acute glaucoma or narrow angle glaucoma. It is much more rare and is very different from open-angle glaucoma in that the eye pressure usually rises very quickly.
This happens when the drainage canals get blocked or covered over, like a sink with something covering the drain.
With angle-closure glaucoma, the iris is not as wide and open as it should be. The outer edge of the iris bunches up over the drainage canals, when the pupil enlarges too much or too quickly. This can happen when entering a dark room.
A simple test can be used to see if your angle is normal and wide or abnormal and narrow.
Symptoms of angle-closure glaucoma may include headaches, eye pain, nausea, rainbows around lights at night, and very blurred vision.
Normal-Tension Glaucoma:
Also called low-tension or normal-pressure glaucoma, in normal-tension glaucoma the optic nerve is damaged even though the pressure in the eye is not very high. Doctors do not know why some people’s optic nerves are damaged even though they have almost normal pressure levels.
Those at higher risk for this form of glaucoma are:
- People with a family history of normal-tension glaucoma
- People of Japanese ancestry
- People with a history of systemic heart disease such as irregular heart rhythm.
Early detection, through regular and complete eye exams, is the key to protecting your vision.

Can Glaucoma Be Prevented?
Is there any way to prevent glaucoma?
Though it’s unclear whether glaucoma can be prevented, you might be able to reduce your risk for the disease by maintaining a healthy lifestyle. Avoid smoking and excessive alcohol, eat a healthy diet, keep your weight down, exercise and take nutritional products.
Currently, regular eye exams are the best form of prevention against significant glaucoma damage. In general, a check for glaucoma should be done:
- Before age 40, every two to four years
- Age 40 to age 54, every one to three years
- Age 55 to 64, every one to two years
- After age 65, every six to 12 months
- Anyone with high risk factors should be tested every year or two after age 35. Those at higher risk include people of African descent, people with diabetes, and people with a family history of glaucoma. You are at increased risk if you have a parent or brother or sister with glaucoma.

January is Glaucoma Awareness Month
Glaucoma has no symptoms and once vision is lost, it’s permanent. As much as 40% of vision can be lost without a person noticing.
The good news is…glaucoma can be detected in its early stages through a comprehensive dilated eye exam. ECT encourages all people at higher risk of glaucoma…(African Americans age 40 or older…everyone age 60, especially Mexican Americans…and those with a family history) to get a dilated eye exam because early detection and timely treatment may save your sight.

Happy New Year’s Eve – Remember These Champagne Safety Tips
New Year’s Eve Eye Safety Tips
New Year’s Eve is one of the worst times of the year for eye injuries. This fact is due to one tradition…the midnight champagne toast. Many people do not know how to correctly open a champagne bottle. When a bottle is opened improperly, the cork is expelled at a high velocity by the gas pressure in the bottle. A champagne cork can fly up to 50 miles per hour. If the cork accidentally strikes the eye, it can lead to serious injuries including internal hemorrhage, traumatic cataract, and torn or detached retinas. To avoid turning a happy celebration into a tragedy follow some very easy rules:
Chill your champagne! Warm champagne creates more pressure behind the cork.
Do not shake the bottle!
Use a towel when opening the bottle.
Point the bottle at a 45-degree angle away from yourself and from anyone else.
Following these few steps can help ensure a safe and happy holiday with no unexpected trips to the emergency room! From everyone at ECT we wish you a Happy New Year and look forward to serving your vision care needs in 2015!

Diabetes and Long Term Eye Damage
High blood sugar can damage the tiny blood vessels that bring oxygen and nutrients to the retina, a critical part of the eye. This is known as diabetic retinopathy, and it can cause progressive, irreversible vision loss. It is the leading cause of new cases of blindness in people between the ages of 20 and 74.
And get this…people with Diabetic-Retinopathy will increase 47% from 2010 to 2030? Our doctors advise patients with diabetes to take an active diligent role in preventing vision loss from diabetic eye disease problems with regular dilated eye exams and health lifestyle choices.
