What Causes Cataracts and How to Treat Them

Melissa Webb • July 28, 2023

Causes of Cataracts

As we age, our eyes go through various changes, and one of the most common issues that develop is cataracts. Cataracts can significantly impact vision, leading to cloudy and blurred eyesight. Understanding the causes of cataracts and the available treatment options can help individuals take proactive steps to maintain their eye health. In this blog post, we will delve into the root causes of cataracts and shed light on the highly successful cataract surgery, offered at Hill Country Eye Center in Austin, to restore clear vision.


Age: The Culprit Behind Cloudy Vision


Cataracts occur when the natural lens of the eye becomes cloudy due to a buildup of protein. This clouding is a result of new cells forming on the outside of the lens, which then compact older cells into the center of the lens, causing it to lose its transparency. While age is the primary risk factor, there are other contributing factors that can lead to cataracts, such as:

  • Advancement in Age: As we grow older, the risk of developing cataracts increases.
  • Eye Injuries: Certain eye injuries can trigger the development of cataracts.
  • Diabetes: Individuals with diabetes have a higher risk of cataract formation.
  • Glaucoma/Retinal Disorders: Pre-existing eye conditions like glaucoma or retinal disorders can be linked to cataracts.
  • Ultraviolet Radiation: Prolonged exposure to UV rays without eye protection can contribute to cataract development.
  • Heredity: Cataracts can be hereditary, passing from one generation to another.
  • Metabolic Conditions: Specific metabolic conditions may also play a role in cataract formation.
  • Cigarette Smoking: Smoking has been linked to an increased risk of cataracts.
  • Air Pollution: Prolonged exposure to air pollution may be associated with higher cataract risk.
  • Heavy Alcohol Consumption: Excessive alcohol consumption may contribute to cataract development.
  • Certain Medications: Some medications, especially long-term use of oral steroids, can increase the likelihood of cataracts.


Cataract Treatment: Cataract Surgery


While vision can be adequately corrected with glasses or contacts for a period, there are currently no medical treatments to prevent or reverse cataract development. Once cataracts begin to affect daily life and compromise vision significantly, cataract surgery is the most effective option.


Cataract Surgery


Cataract surgery is a highly successful and common procedure that restores clear vision. Performed on an outpatient basis, cataract surgery involves removing the cloudy natural lens and replacing it with a clear, artificial lens known as an intraocular lens (IOL). More than 1.5 million cataract surgeries are conducted each year in the United States, with over 90% of patients experiencing improved vision following the procedure.


Cataracts are a prevalent age-related eye condition that can impact the quality of life significantly. Understanding the causes of cataracts empowers individuals to take proactive steps to protect their vision. If cataracts affect daily life and hinder vision, cataract surgery offered at Hill Country Eye Center in Austin provides an effective solution to restore clear vision. With advanced surgical techniques and intraocular lens options, cataract surgery has proven to be highly successful in helping individuals regain visual clarity and enhance their overall well-being.

Cataracts Diagnosed
May 28, 2024
Are you experiencing cloudy or blurred vision, particularly at night or in bright light? These symptoms could indicate the presence of cataracts, a common eye condition that affects millions of people worldwide. At Hill Country Eye Center in Austin, Texas, we understand the importance of early detection and treatment for cataracts. In this blog post, we'll explore how cataracts are diagnosed and what steps you can take to preserve your vision. Understanding Cataracts Cataracts occur when the natural lens of the eye becomes cloudy or opaque, leading to a gradual loss of vision. This clouding is often caused by the natural aging process, but cataracts can also develop due to factors such as genetics, ultraviolet light exposure, smoking, and certain medications. Diagnosing Cataracts: The Process Diagnosing cataracts typically involves a comprehensive eye examination performed by an experienced ophthalmologist or optometrist. Here's what you can expect during the diagnostic process: Visual Acuity Test: Your Austin eye doctor will begin by assessing your visual acuity, or how well you can see at various distances. This may involve reading an eye chart to determine if you have any difficulty seeing objects clearly. Slit-Lamp Examination: During a slit-lamp examination, your eye doctor will use a special microscope called a slit lamp to examine the structures of your eye, including the lens. This allows them to assess the clarity and transparency of the lens and detect any signs of cataracts . Dilated Eye Examination: To get a better view of the back of your eye, your eye doctor may perform a dilated eye examination . This involves using eye drops to temporarily widen your pupils, allowing them to examine the lens and other structures more closely. Other Tests: In some cases, additional tests such as optical coherence tomography (OCT) or a glare test may be performed to further evaluate the extent of the cataract and its impact on your vision. Treatment Options for Cataracts in Austin If cataracts are detected during your eye examination, your eye doctor will discuss treatment options with you. In the early stages, cataracts may be managed with changes to your eyeglass prescription or lifestyle modifications. However, as cataracts progress and begin to interfere with your daily activities, cataract surgery may be recommended. Early detection and diagnosis are crucial for effectively managing cataracts and preserving your vision. If you're experiencing symptoms of cataracts or are due for a routine eye examination, don't hesitate to schedule an appointment with the experienced team at Hill Country Eye Center in Austin, Texas.
