Dear Subscriber,
I have received several emails that the entire cataract report did not come over to you so I am pasting it again here for your review. Sorry for technical difficulties.

Can Cataracts Grow Back After Surgery? Understanding the Possibilities and What to Expect
Cataract surgery is one of the most common and successful procedures performed today, offering millions of people the chance to regain clear vision. However, after undergoing this life-changing surgery, some patients may wonder: Can cataracts grow back after surgery? The short answer is no, but there’s more to the story. Let’s explore what happens after cataract surgery, why some people experience vision changes later on, and how to ensure your eyes stay healthy long-term.
What Are Cataracts?
Before diving into the specifics of post-surgery outcomes, it’s important to understand what cataracts are. A cataract is a clouding of the eye’s natural lens, which lies behind the iris and the pupil. This clouding occurs due to the clumping of proteins in the lens, leading to blurry vision, difficulty seeing at night, and sensitivity to light. Cataracts are most commonly age-related, though they can also result from injury, certain medications, or other medical conditions.
What Happens During Cataract Surgery?
Cataract surgery involves removing the cloudy natural lens and replacing it with a clear artificial lens, known as an intraocular lens (IOL). The procedure is typically quick, taking only about 15 to 30 minutes, and it’s performed under local anesthesia. Most patients experience a significant improvement in vision within a few days, with full recovery expected within a few weeks.
Can Cataracts Grow Back After Surgery?
The short answer is no—once the cloudy lens is removed, it cannot regrow. However, some patients may experience a condition known as posterior capsule opacification (PCO), which is often referred to as a "secondary cataract." While PCO is not an actual cataract, it can cause similar symptoms and may lead to confusion.
What Is Posterior Capsule Opacification (PCO)?
During cataract surgery, the natural lens is removed, but the thin membrane that holds the lens (called the lens capsule) is left intact to support the new intraocular lens. Over time, this capsule can become cloudy due to the growth of residual lens epithelial cells. This clouding can cause symptoms similar to those of the original cataract, including:
Blurry Vision: Vision may become hazy or cloudy, similar to how it felt before cataract surgery.
Glare and Halos: You might notice more glare from lights or halos around bright objects, particularly at night.
Difficulty Reading or Seeing Fine Details: The clouding can make it harder to see small print or details clearly.
Decreased Contrast Sensitivity: Colors and contrasts may appear less vivid or sharp.
How Common Is PCO?
PCO is relatively common, with about 20% to 30% of cataract surgery patients developing this condition within the first few years after surgery. The good news is that PCO is treatable, and the solution is straightforward.
How Is PCO Treated?
The most effective treatment for PCO is a quick and painless procedure called a YAG laser capsulotomy. During this procedure, the ophthalmologist uses a laser to create a small opening in the cloudy capsule, allowing light to pass through clearly. The procedure is typically done in the doctor’s office, takes only a few minutes, and does not require any incisions. Most patients notice an immediate improvement in their vision after the procedure.
What to Expect During and After YAG Laser Capsulotomy:
Before the Procedure: You’ll receive eye drops to dilate your pupil and numb the eye. The procedure itself is quick and painless.
During the Procedure: You’ll sit at a machine similar to the one used for an eye exam, and the doctor will focus the laser on the cloudy capsule. The laser creates a small hole in the capsule, restoring clear vision.
After the Procedure: Most people experience a significant improvement in vision immediately after the procedure. There’s no recovery time needed, and you can resume your normal activities right away.
How to Maintain Clear Vision After Cataract Surgery
While cataracts can’t grow back, and PCO is treatable, it’s important to take steps to maintain your vision after cataract surgery. Here’s what you can do:
Attend Regular Eye Exams
Regular check-ups with your ophthalmologist are crucial for monitoring your eye health and detecting any changes in your vision early. Even if you feel your vision is fine, routine exams can catch issues like PCO or other eye conditions that may develop as you age.
Protect Your Eyes from UV Light
Wearing sunglasses that block 100% of UV rays can help protect your eyes from potential damage and prevent other eye conditions from developing.
Manage Your Overall Health
Conditions like diabetes, high blood pressure, and smoking can increase the risk of developing eye problems, including those that might affect your vision after cataract surgery. Maintaining a healthy lifestyle can help preserve your eye health.
Report Any Vision Changes
If you notice any changes in your vision, such as blurriness, glare, or difficulty reading, contact your ophthalmologist right away. Early intervention can prevent complications and keep your vision clear.
Consider Your Options for Vision Correction
If you’ve had cataract surgery but still experience vision issues like astigmatism, you might benefit from additional treatments or corrective lenses. Discuss your options with your eye doctor to find the best solution for your needs.
Conclusion
Cataract surgery is a highly successful procedure that can dramatically improve your vision and quality of life. While cataracts themselves cannot grow back after surgery, it’s possible to develop a condition called posterior capsule opacification (PCO), which can cause symptoms similar to a cataract. Fortunately, PCO is easily treatable with a quick and painless laser procedure.
Maintaining regular eye exams and taking good care of your overall health can help you enjoy clear vision for years to come. If you’ve had cataract surgery and are experiencing any changes in your vision, don’t hesitate to reach out to your ophthalmologist. Early intervention is key to preserving your eyesight and ensuring that you continue to see the world clearly and vividly.
My wife has been using castor oil drops in her eyes for over over five years. She is 73. One drop in each eye every day. She went from seeing rings around lights to clear vision in just a few days plus it cleared up floaters, dry eyes, and wrinkles around her eyes.
Barbara O’Neill highly recommends castor oil on eyelids.
