Low vision and the use of eyeglasses or contact lenses may be a source of inconvenience to many, and laser vision correction operations have become the easiest way to get rid of this inconvenience. But we have been hearing a lot lately about the femto-lasik operation, so let’s dear reader review what is the femto-lasik operation? What are its advantages and disadvantages? And all other details about the process that you may need to know.

What is the femto-lasik operation?

Femto Lasik is one of the LASIK vision correction surgeries in which the cornea is corrected using laser beams. Femto LASIK eye surgery is used to correct double vision and corneal refractions. There is also a so-called femto-lasik HD and it is used in cases of correcting vision if you suffer from some deviations in the cornea.

What are the advantages of femto-lasik surgery?

There are many advantages to this process, including:

1. It is used to treat nearsightedness, astigmatism and low vision.
2. No surgical tools are used, but the doctor uses laser beams to remove the outer layer of the cornea.
3. You need a short time to recover and then return to normal daily life.
4. Painless procedure.
5. You do not need general anesthesia.
6. Very accurate procedure.
7. The eyes are less likely to dry out after undergoing the procedure.
8. This operation is suitable for cases where the cornea is not thick.

What are the disadvantages of femto-lasik operation?

Although it is one of the advanced techniques in vision correction operations, it has some disadvantages, including:

1. Vision may weaken again with age after the operation.
2. You can be exposed to the accumulation of some air bubbles on the cornea and this is called (Opaque Bubble Layer OBL).
3. Transient Light Sensitivity Syndrome, which may occur several days or weeks after the procedure, can be treated with cortisone drops.
4. It can cause rainbow glare, which is seeing multiple colors like an arc when looking at white light.

Who are the candidates for femto-LASIK surgery?

There are several conditions to be a candidate for this process, namely:

1. Be 18 years of age or older.
2. The measurements of visual strength should be constant over the previous year before undergoing the operation.
3. You should not be a diabetic or a breastfeeding woman, as they affect the stability of vision.
4. You do not suffer from any disease or take any medications that may affect the speed of wound healing.
5. The thickness of the cornea should be good, but if its thickness is small, it is not possible to undergo the procedure.
6. Not to undergo other types of laser vision correction operations previously.
7.  You cannot undergo this procedure if you suffer from one of these eye diseases which are dry eyes, any viral eye disease, herpes, glaucoma or keratoconus, or if you have any eye infections, iritis, or high eye pressure.

Is femto-lasik suitable for vision correction in the case of keratoconus?

For femto-LASIK and keratoconus, keratoconus treatment and vision correction may be confused. Keratoconus is the protrusion of the cornea into a cone shape, causing poor vision.

Let us, dear reader, agree now that femto-LASIK is not used to correct double vision in cases of keratoconus, but is used in cases of severe vision impairment, as it is used to install rings around the cornea to improve vision.

Femto Lasik price

The cost of the operation depends on several factors, including:

• Doctor skill & efficiency.
• The center’s location and reputation.
• How weak your eyesight is.
• Check-ups and tests you need before and after the procedure.

What are the steps of the femto-lasik process?

The femto-LASIK procedure, which takes about 30 minutes, includes the following steps:

1. You will lie on your back under the lasers and several computer monitors in the operating room.
2. The doctor numbs the eye locally by placing an anesthetic drop in it.
3. The doctor fixes the eyelids to keep the eye open using a device called an endoscope.
4. He then places a suction device near the body of the eye to facilitate suction during the procedure.
5. The doctor places a glass lens on the cornea and then shines a laser beam to remove the outer layer of the cornea and then bend it.
6. Then the rays are directed to the part below the layer that was removed to correct the vision.
7. Then he puts that outer layer back on again.
8. You may hear a cracking sound or smell something burning during the procedure, which is normal, so don’t worry.

When does the sight return to normal after the femto-lasik operation?

Vision continues to fluctuate for the first few months after surgery. It takes three to six months to see the full effect of the operation.

What is the difference between LASIK and femto-LASIK and femto-smile?

LASIK: The doctor removes the outer layer of the cornea using a surgical scalpel designed for the eye and then shines a laser beam to correct the shape of the cornea, and then restores the outer layer again.

Femtolasik: Here he also removes the outer layer of the cornea, but using laser beams, then corrects the shape of the cornea with a laser as well, and then restores that layer of the cornea.

Femto Smile: The outer layer of the cornea is not removed, but the doctor makes a small incision using a laser, and then shines a laser beam on the lower part of the incision to correct the shape of the cornea; This makes this procedure suitable for people with thin corneas and also makes the eye less prone to dryness.

Is there a difference between femto LASIK and traditional LASIK?

Yes, there is a difference between traditional LASIK and femto lasik, as we mentioned before, which is the removal of the outer layer of the cornea using a surgical scalpel in traditional LASIK, while that layer is removed using a laser in femto LASIK; Which makes it safer and more accurate, and also makes the doctor more control over the thickness of the outer layer removed, making femto-LASIK a way to correct vision for people with a thick cornea.
