What is Cataract?
Cataract is a severe condition in the eye where the patient complains about clouding of vision. This usually affects people over 45. At first, you might not notice much change. But over time, your vision gets hazy. Simple tasks like reading or driving become harder. Even recognizing faces can be a challenge! Unfortunately cataracts don’t go away naturally, as a result surgeons suggest surgery to the patients. During this procedure, doctors remove the cloudy lens and replace it with an artificial clear lens. Usually, the procedure is safe. But, since it is a surgery, there can be 1% of risk factors which can take place due to infection, swelling or redness. Yet for most of us, the benefit which surgery offers possesses higher weight than risk. After all, clearer vision can greatly improve your daily life!
Different Types of Cataracts
- Nuclear: • Forms in lens center • Often age-related • Affects light focus
- Cortical: • Starts as small bumps on lens surface • Grows inward, creating wedge-shaped opacities • Can be caused by diabetes or UV exposure
- Posterior Subcapsular: • Develops at back of lens • Progresses rapidly • May cause glare and reduced vision • Risk factors: age, steroid use, smoking
- Congenital: • Present at birth or in childhood
- Secondary: • Results from other conditions (e.g., diabetes, glaucoma, uveitis) • Can be caused by steroid use
- Traumatic: • Follows eye injury • May develop immediately or over time
What are the Causes of Cataracts?
Age:
- The primary culprit
- More common in older adults
- Lenses become less flexible and cloudy over time
Lifestyle Factors:
- Smoking: Contains harmful toxins
- Excessive alcohol: Can dry out eyes and contribute to cataract formation
- UV exposure: Prolonged sun exposure increases risk
Health Conditions:
- Diabetes: Elevates cataract risk
- Hypertension and obesity
- Certain skin diseases
Genetic Factors:
- Family history can increase risk
Nutritional Aspects:
- Inadequate Vitamin C: May lower lens quality
Other Contributors:
- Eye injuries or trauma
- Radiation exposure
- Long-term use of corticosteroids
- Hormone imbalances (during pregnancy or menopause)
Eye Injuries: Trauma to the eye.

Importance of Cataract Surgery
The Cataract Surgery Process
Initial Consultation: What to Expect
During the initial consultation, your ophthalmologist will perform a comprehensive eye exam to assess the extent of the cataract and overall eye health. This may include:
- Visual acuity test
- Dilated eye exam
- Tonometry to measure eye pressure
- Ultrasound test to measure the size and shape of the eye
Preparing for Surgery: Pre-operative Instructions
Prior to surgery, patients are given specific instructions to ensure a successful procedure:
- Stop taking certain medications that can increase bleeding risk.
- Use prescribed eye drops to prevent infection and reduce inflammation.
- Arrange for transportation on the day of surgery.
The Day of Surgery: Step-by-Step Procedure
On the day of surgery, the process typically involves:
- Local anesthesia to numb the eye area.
- Making a small incision in the cornea.
- Using ultrasound waves (phacoemulsification) to break up the cloudy lens.
- Removing the fragmented lens pieces.
- Inserting an artificial intraocular lens (IOL) to replace the natural lens.
- Closing the incision (often self-sealing, requiring no stitches).
Post-Surgery Care
- Post-surgery care is crucial for a smooth recovery:
- Use prescribed eye drops to prevent infection and inflammation.
- Avoid rubbing or pressing on the eye.
- Wear an eye shield while sleeping.
- Attend follow-up appointments to monitor healing.
