LASIK is a vision correction surgery. It is a laser refractive surgery that reshapes the front surface of the cornea of the eye. This allows light entering the eye to focus on the retina at the back of the eye without glasses or contact lenses.
What Is Happining During The Operation?
During the process, the following steps are followed:
1- The patient is subjected to local anesthesia in the eye by means of a few anesthetic eye drops that are dripped into the eye about 10 minutes before the start of the surgery.
2- After confirming the effectiveness of the anesthesia, the doctor uses laser beams from a special device to make an incision in the surface of the cornea without separating it completely, which allows most of the surface tissue of the cornea to be removed from the inner tissue of the cornea.
3- Then the doctor shines a laser beam of another type directly on the cornea in order to correct vision problems, and at this stage the patient must look directly at the laser light for a short period.
4- The last step is to put the surface tissue back in place and cover the cornea again after completion.
Types of Lasik and The Difference Between Them:
Surface Lasik:
A type of eye surgery that is performed using a laser and works to correct refractive errors by changing the shape of the cornea, given that the cornea is responsible for the refraction of light towards the center of the retina.
Where this technique works to change the features of the cornea, which makes the light refracted properly, and is an effective treatment for people who suffer from farsightedness and shortsightedness.
This technique is suitable for people who have a very thin corneal surface, as well as people with dry eyes and sports people.
Surface laser technology is one of the best options for people who are at risk of eye injury, such as certain professions and jobs that are susceptible to eye injury, so the doctor usually checks the type of profession or job of the patient to choose the type of operation suitable for him.
Laser conventional (lasik):
It is defined as a surgical procedure performed using a specific type of laser beam to correct vision defects and vision problems resulting from refractive errors.
Where it is known that normal vision is through the passage of light through the lens and cornea of the eye, which works to break the light to fall on the retina.
Therefore, when there are problems in the lens or the cornea of the eye, this prevents the light from being bent in the required manner, and therefore it is not focused on the retina, so the vision becomes blurry.
The ophthalmologist uses LASIK, which helps to improve the way light rays focus on the retina and treat vision problems such as:
1- Myopia
2- Farsightedness
3- Astigmatism
Femto Lasik:
Femto-LASIK is a type of LASIK operation and is used to treat vision and corneal problems. It is known as blade-free LASIK. Femto-LASIK is a safer technology than traditional LASIK.
It is necessary to warn the patient to refrain from rubbing the eye, to avoid direct exposure to light or sunlight, to stay away from high temperatures, and it is preferable to wear sunglasses after completing the operation.
The Reason for The Lasik Procedure
Nearsightedness:
When the eyeball is a little longer than normal or when the cornea is curved too sharply, light rays focus in front of the retina and blur distant vision. You can see close objects fairly clearly, but have difficulty seeing things that are far away.
Farsightedness:
When you have a shorter-than-average eyeball or a very flat cornea, light is focused behind the retina instead of on the eyeball. This makes near vision and sometimes distance vision blurry.
Astigmatism:
When the cornea curves or flattens unevenly, it results in what is called astigmatism, which causes both near and far vision problems.
FAQ
What are the best types of vision correction operations?
Vision correction operations are not limited to the types of LASIK operations only, but also the surface LASIK technique is used to correct vision, as well as corneal ring transplantation to treat keratoconus problems or the use of contact lenses and other techniques.
Which is better LASIK or femto smile?
When talking about the types of LASIK and the best of them, we must know that each type has advantages as well as disadvantages, and preference is between the types of LASIK according to the disease and the doctor’s choice of the appropriate type for the case.
When does vision improve after LASIK?
The eyes are completely healed once the LASIK operation is completed, and vision improves clearly from 24 hours to 48 hours. Also, the duration varies according to the type of operation that the patient underwent.
When does the eye blurry end after the completion of the operation?
The patient may feel dryness in the eyes or glare in the eyes after the operation, but these symptoms are normal and temporary, but if you feel that they persist, you should inform your doctor about that.
Things To Consider
1- Avoid driving a car immediately after completing the LASIK operation, due to the possibility of blurring of vision.
2- Be sure to use the necessary drops that your doctor prescribed for you, and not to forget any dose to avoid complications or pain. It is also preferable to close your eyes for 5 minutes after each dose, in order to relax the eyes.
3- Avoid reading after the operation or using the mobile phone for a long time to avoid eye fatigue and stress
4- It is recommended to wear sunglasses after the operation in order to reduce the effect of light or sunlight on the eyes
5- Avoid using make-up and cosmetics, especially those that are applied to the eye, until the doctor allows you to do so
