A way to say goodbye to glasses! Let's learn about Refractive Lens Exchange in a simple way.

Are you tired of looking for your glasses or contact lenses every morning after waking up? Are you tired of getting your glasses wet when it rains, fogging up, and having to clean them all the time? Maybe you're a sports person, and then these glasses are a big hassle. So many people think that there is no solution to this, that you have to live like this for the rest of your life. But in fact, there are modern medical methods that can say goodbye to these glasses and clear your vision . Today we are talking about one such special surgery.

What exactly is Refractive Lens Exchange (RLE)?

Simply put, this is also an eye surgery. However, this involves completely removing the natural lens inside your eye and permanently implanting an artificial lens (Intraocular Lens - IOL ) that is designed to fit your own vision defect.

Think of it like having a small lens with the same power as your eyeglasses or contact lenses inserted into your eye. Once the artificial lens is implanted, it works just like your natural lens. It focuses light entering your eye and focuses it directly on the retina . This allows you to see clearly without blurring. Many people never need to wear glasses again after this surgery. Some people may only need glasses for close-up tasks, such as reading a book or newspaper.

You may have heard of laser surgeries, such as `(LASIK)` and `(PRK)`. These surgeries change the shape of the cornea of ​​the eye to improve vision. But some people, especially those with severe vision problems (nearsightedness or farsightedness), cannot have these laser surgeries. That's when doctors suggest `(Refractive Lens Exchange)` surgery.

Who is this surgery best for? (And who is it not for?)

This surgery is not for everyone. Your eye surgeon will examine your eyes and decide whether this is right for you. The table below will give you a good idea of ​​this.

Does age matter?

This surgery is usually best for people over the age of 40. There are several reasons for this. One is that older people are less likely to have complications after the surgery. Another is that many people over the age of 40 already have some degree of nearsightedness (presbyopia). So this surgery can solve that problem all at once.

What is the difference between cataract surgery and this?

This is something that many people are confused about. Both of these surgeries involve removing the natural lens of the eye and replacing it with an artificial lens (IOL). However, the reason for the surgery is completely different.

• Cataract surgery: This is done because the natural lens in your eye has become cloudy (like a foggy glass). This clouding is interfering with your vision. So the cloudy lens is removed and a clear artificial lens is inserted to restore clear vision. This is a medical necessity .
• Refractive Lens Exchange (RLE) surgery: This is done to correct vision problems (such as nearsightedness or farsightedness) that occur when your natural lens is clear , but cannot focus light properly. The problem here is not a clouding of the lens, but a focus problem . This is done to reduce your dependence on glasses or contact lenses and make everyday life easier. Therefore, this is an elective surgery rather than a medical necessity.

How do you prepare before surgery?

Your eye surgeon will thoroughly examine your eyes before surgery and will discuss with you the types of intraocular lenses (IOLs) that may be implanted. It is important to ask any questions you may have at this time.

There are several main types of IOLs:

• Monofocal IOLs: These lenses can either provide clear vision at a distance or at a distance . They cannot provide both. For example, if you wear these lenses for distance vision, you will definitely need glasses for close-up tasks like reading a book or checking your phone.
• Multifocal IOLs (lenses that provide both distance and near vision): These lenses allow you to see both distance and near objects without glasses. However, they do have some disadvantages. Some people may experience glare and halos when driving at night. These usually disappear over time.
• Monovision method: This is a very interesting method. What you do here is to put a ``monofocal`` lens for distance vision in one eye and a ``monofocal`` lens for near vision in the other eye. Although it feels a little strange at first, after a while your brain gets used to this and you start to see both distance and near without realizing it.

Talk to your doctor to decide which of these options best suits your lifestyle, job, and needs.

How is the surgery done?

There is no reason to be afraid of this surgery. It usually takes about 15-30 minutes to complete. The steps involved in the surgery are as follows:

1. First , eye drops are put in your eye to numb it . So you won't feel any pain. If necessary, you may be given a sedative to keep you calm. You will be conscious, but your vision will be blurry. All you can see is a light and some movement.

2. Next, the surgeon uses a laser beam or a very fine blade to make a very small incision where the white of the eye (sclera) and the cornea meet.

3. Then, using a pen-shaped instrument (phacoemulsification), your natural lens is broken into small pieces and carefully suctioned out.

4. Now, the previously selected artificial lens (IOL) is inserted into the created space through that small incision and positioned correctly inside the delicate lens capsule that holds the lens.

5. This cut is so small that it doesn't even need stitches . It will close and heal on its own.

6. Finally, you will be transferred to the ward with a small eye shield attached.

What happens after the surgery?

After the surgery, you will be observed for about 30 minutes and then allowed to go home. It is essential that someone comes to take you home. Also, you should have someone to take you to your first clinic appointment after the surgery. The doctor will tell you when you can drive again.

It is normal to experience some discomfort in the first few days after surgery. These are temporary.

• Slight blurring of vision
• Double vision
• Itching in the eyes, as if there is sand in them.
• Redness of the eyes
• Tears flowing from the eyes

These will disappear completely over time. Some people may also experience visual side effects from the intraocular lens (IOL).

• Looks like a shadow when viewed from the side
• Seeing a glowing line of light when viewed from the side
• Seeing halos or glare around lights, especially at night

These are more common in people who have multifocal IOLs, and often decrease over time as the brain adjusts to them.

What are the benefits and risks of this surgery?

Like any surgery, this one has both benefits and risks. Having this surgery performed by an experienced, skilled eye surgeon can greatly reduce the risks.

When should you see a doctor?

It is normal for the eye to experience some changes during the healing period after surgery, but there are some symptoms that we should be especially aware of.

What other options are there besides this surgery?

Refractive Lens Exchange is not for everyone. There may be other options that are right for you.

• Glasses or Contact Lenses: This is the simplest and most non-invasive option.
• Laser surgery (LASIK, PRK): These may be suitable for people with mild to moderate vision problems.
• Phakic Intraocular Lens (PIOL) Implantation: This involves implanting a new lens in front of your natural lens without removing it. It's like putting a contact lens inside your eye. This is a good option, especially for people under the age of 40 who have severe nearsightedness but haven't yet started to experience nearsightedness.

The most important thing is to talk to your ophthalmologist about each of these options, their pros and cons, and choose what is best for you.
