Is Refractive Lens Exchange Permanent?

If you’re thinking about getting cataracts removed, you may be wondering if refractive lens exchange is a permanent solution. The short answer is that it depends on the type of lens exchange surgery you undergo. In general, however, refractive lens exchange is considered to be a permanent solution for many people.

What is refractive lens exchange?

Refractive lens exchange (RLE) is a procedure used to correct certain types of vision problems. In RLE, a patient’s own lenses are removed and replaced with new, corrected lenses. RLE is considered to be a permanent solution to vision problems and is generally considered to be more successful than other treatments, such as eyeglasses.

How does it work?

Refractive lens exchange is a surgical procedure in which an artificial lens is placed into the eye to correct its refractive error. The surgery is done through a small incision in the corner of the eye.

The artificial lens replaces the natural lens in the eye, which is responsible for providing sharp vision. With refractive lens exchange, your prescription will change over time as your eyes naturally change. However, the artificial lens should last for the lifetime of your glasses or contact lenses.

If you are considering RLE, be sure to discuss all of your options with your doctor, and if you don’t have one, you can make an appointment at There are many factors to consider, including your health and vision goals.

Is refractive lens exchange permanent?


When a patient has cataracts, the lens in their eyes becomes cloudy. The cloudy lens blocks light from entering the eye, causing a decrease in vision. In some cases, the lens can become so cloudy that it cannot be removed without causing serious harm to the eye. Refractive lens exchange (RLE) is a procedure used to replace a person’s old lenses with new ones that have been specially designed to correct his or her vision.

Most people believe that RLE is permanent and that they will never need to have it done again. However, this is not always the case. Many patients who have had RLE experience a gradual loss of vision over time. This is due to the fact that the new lenses are not as good as the old ones at correcting vision. Over time, the patient may find that he or she needs to have RLE performed more often than originally planned in order to maintain good vision.

What to expect during a refractive lens exchange procedure

Many people are anxious about the surgery itself, but there are many things to expect before, during, and after the surgery. Here are some basics:

Before the Procedure

You should schedule a consultation with a refractive surgeon to discuss your individual situation and see if a refractive lens exchange is right for you. At this appointment, your surgeon will examine your eyes and give you an estimate of the cost and time required for the procedure.

During the Procedure

The surgery is usually performed under general anesthesia. You will be asleep throughout the entire process. Your surgeon will make several small incisions in your skin and insert a telescope into your eye to remove your old lenses. Once the lenses are removed, he or she will place new lenses into your eye. The surgery usually takes about one hour.

After the Procedure


Your vision may be blurry for a few days after the surgery, but most people regain their normal vision within two weeks. You may experience some discomfort at first, but it should dissipate over time. If you experience any problems following the surgery, please contact your doctor.

The Pros and Cons of Refractive Lens Exchange

One of the biggest benefits of RLE is that it can correct vision problems that cannot be corrected with other methods, like glasses or contact lenses.

There are many benefits to RLE, including:

  1. Reducing eyestrain and fatigue.
  2. Improving your vision by adding new lens power to your eye.
  3. Improving your overall quality of life by improving your vision and reducing the amount of time you need to spend wearing glasses or contacts.
  4. Reducing the risk of eye diseases such as cataracts and glaucoma.
  5. Enhancing your appearance by giving you a more youthful appearance.

However, RLE does have some limitations.

There are a few potential risks associated with this surgery: infection, pain, and eye damage. Infection is the most common concern, as exchanging lenses can lead to the transfer of bacteria and other contaminants from one eye to the other. Pain can also be a problem, especially if the lenses are removed too quickly or without anesthesia – which is almost impossible. In rare cases, the exchange can lead to permanent damage to the eyesight.

To minimize the risks associated with reflective lens exchange, it’s important to follow all of the guidelines provided by your doctor. Likewise, make sure to clean and sanitize your hands thoroughly before and after the procedure. And be sure to notify your doctor if you experience any pain or difficulty during or after RLX.



As we get older, our eyes can start to suffer from the effects of presbyopia, which is the natural process by which our eyes become less able to focus on close objects. If left untreated, this condition can lead to a number of problems such as difficulty reading and driving, and even more serious issues like blurred vision and eye fatigue. Fortunately, there is help available – refractive lens exchange (RLE), also known as laser iridotomy or cataract surgery. RLE is a relatively simple procedure that removes your old lenses and replaces them with new ones that have been customized for your individual needs. Although it may be temporary in nature, RLE is often considered permanent because it fixes your optical errors permanently. If you are thinking about undergoing RLE but are worried about the long-term impact it might have on your vision, read more information on the topic here before making a decision.
