on your condition

Have you recently been thinking of getting rid of your contact lenses and eyeglasses by undergoing refractive surgery? The most important information you will find in the following article. If you want to undergo a vision correction operation, here is the most important information that you should know about this medical procedure: Types of vision correction operations Vision correction operations are not limited to:

Not only is Zak, but there are several other options available, so let''s get to know them as follows:

1. Corneal Refractive Surgery (PRK)

In this type of vision correction process, special laser beams are used to correct the shape of the cornea, and this surgery is the first type of laser vision correction process that began to be used before the introduction of the types that we will enumerate next.

This surgery is not very common compared to other types, but it is still used in some cases, and sometimes it may be the best option, especially if the patient''s cornea is thin by nature.

It is worth noting here that this process

It takes a long period of time to fully recover compared to other refractive surgery.

Its cost is not much different from other types.

Sometimes it causes general discomfort in the eye in the post-operative period.

2. LASIK

In this type of refractive surgery, laser beams are usually shone directly on the eyeball after making an incision in the cornea, removing the outer tissue from it and folding it to reveal the tissue below it and shining the laser beam on it.

LASIK is suitable for people who want to correct farsightedness, nearsightedness, or astigmatism problems in general.

3. SMILE technology

In this modern technique of vision correction, laser beams are used to perform the correction without the need to make any incisions in the eye tissues, which reduces the chances of any disturbing symptoms appearing after the operation.

The SMILE technology is suitable for people who suffer from myopia, and it is also excellent and an ideal option for those who suffer from chronic dry eyes.

It should be noted here that the recovery period from a vision correction process of this type may take longer than that required by LASIK technology, for example.

4. Implantation of corneal rings (ICR)

In this type of vision correction surgery, two rings made of a special material are implanted on both ends of the cornea after making a superficial incision in the cornea.

This process is usually used to correct myopia and astigmatism problems related to keratoconus.

5. Superficial Keratotomy (RK)

This type of operation is relatively old, and a special tool was used through which the ophthalmologist made incisions and corrected the shape of the cornea manually.

Although this type may sound scary, it was successful in the pre-laser era and was effective in treating myopia.

6. Lens Replacement (RLE - RLR - CLE)

Here, the surgeon makes a small incision to remove and discard the natural lens of the eye, then replace it with a lens made of silicone or plastic.

The patient is subjected to this operation in cases where the imbalance and degrees of visual impairment are somewhat large, and it is also possible to perform it to correct other problems, such as: dry eye.

7. Other options and technologies

Vision correction operations do not stop at the aforementioned types only, but there are many other types, such as:

Femtosecond laser-assisted.

Clear lens extraction (PRELEX).

Thermal laser (LTK).

Are you eligible for vision correction?

Before subjecting the patient to a vision correction process appropriate to his condition, his condition is first evaluated, as it is required that certain criteria apply to him first.

These are the most important criteria that must apply to a patient who is a candidate for laser vision correction:

The patient must be over 18 years old.

The patient''s visual impairment should be relatively stable in the last year preceding the operation.

That the person does not have an eye disease, such as: cataract and glaucoma.

The candidate should not have one of the following diseases

lupus

Diabetic retinopathy.

Rheumatoid arthritis.

The candidate should not be pregnant or breastfeeding.

Risks and complications of vision correction operations

Vision correction operations may include some common complications and some rare ones, the most important of which are:

Surgery may cause a deep wound in the tissues of the inner eye ball in cases of thin cornea, which requires stopping the operation immediately.

A defect may occur in the incision made in the outer tissue of the cornea, which may also require stopping the operation immediately.

Infections and ulcers may occur in the eye in the period following the operation.

The patient may experience temporary dry eyes.

There are other symptoms that may appear after the vision correction process and necessitate going to the doctor immediately if they appear and are considered a medical emergency, such as:

severe pain in the eye

Vision loss or sudden blurred vision.

General redness of the eye.
