Many users of medical glasses and contact lenses dream of abandoning them forever and not committing to using them, in addition to feeling that they are more beautiful and better psychologically without using medical glasses. Therefore, we discuss together the types of vision correction operations and what are the requirements for these operations and warnings as well.
Types of vision correction:
There are many operations to correct vision, in which the doctor uses local anesthesia points in the eye to anesthetize the eye and prevent its sensation because it is performed on the patient while he is fully absorbed and without the use of full or partial anesthesia. Vision correction operations last between 10-20 minutes for the eyes, especially for operations that are performed using laser.
Vision correction operations are not considered a cosmetic operation, as they are completely different in their goals from eye plastic surgery, as the operations mainly aim to correct vision, increase its intensity, and improve vision in patients.
1- The famous traditional LASIK:
1_The process relies on shining laser light on the inner tissues of the cornea to modify the surface of the cornea.
2 _LASIK is suitable for correcting vision for all cases of nearsightedness and farsightedness.
2- Refractive surgery- PRK photorefractive keratectomy:
It is one of the first vision correction operations that doctors resorted to to adjust and correct the surface of the cornea, and doctors do not resort to it now except in cases of a very thin cornea, and it is the most appropriate operation for cases of short and medium farsightedness and cases of astigmatism.
3- SMILE small incision lenticule extraction:
The SMILE technique is one of the latest types of vision correction operations, and it depends on correcting the vision on the inner layer of the cornea, which results in a more stable cornea that is less dry and better in vision compared to LASIK technology. It is the ideal choice for those who suffer from dry eyes, but it is not useful in cases of farsightedness and astigmatism It is recommended that it be performed by an experienced physician.
4- RLE refractive lens exchange:
The process of implanting lenses depends on replacing the affected lens with a new one, and it is one of the techniques for correcting vision for those who have a very thin cornea, for whom LASIK operations are of no use.
5- Correction of astigmatic cornea- AK Astigmatic Keratonomy:
People with astigmatism suffer from an uneven cornea with a football-like surface. The doctor makes an incision on both sides of the steeper cornea, which makes it relax and return to its natural round shape, and then correct the vision.
6- PRELEX Presbyopic lens exchange:
Some patients suffer from difficulty seeing on close objects, this condition is called presbyopia due to the lens losing its flexibility, using the PRELEX technique, the doctor implants a new multifocal lens to restore flexibility, correct vision and increase focus.
Who are the candidates for vision correction operations?
There are some requirements that must be met by the patient before the operation, including:
The patient’s age must be over 18 years.
The patient’s vision should be stable at a specific degree for a period of not less than a year.
The patient should not be in old age, as these operations do not give satisfactory results at an old age.
The patient should not have keratitis, keratoconus, or glaucoma.
The patient should not have any immune diseases such as rheumatoid arthritis, lupus or AIDS.
In cases of pregnancy and lactation, please consult your doctor before performing the operation. It is best to wait until the period of pregnancy and lactation ends, and then undergo the operation.
Complications of refractive surgery:
Some complications of the vision correction process appear like any other operation, and a cosmetic doctor advises the importance of discussing the complications that may occur with the doctor before undergoing the operation, including:
Severe eye infections and eye redness for a period after the operation.
Dry eye, which requires continuous use of moisturizing eye drops for at least 6 months after the operation.
The surgery can cause a deep wound in the inner eye tissues, which requires stopping the operation immediately.
In some rare cases, sudden loss of vision, severe blurred vision, or severe eye pain may occur, which requires an immediate visit to the doctor.
Post-op instructions:
There are some instructions that the patient must follow to avoid any problems or complications after the operation:
Avoid exposure to wind and dust after the operation.
Not using cosmetics for the eye area and around it for a period of not less than two weeks.
Wear sunglasses in the morning to protect your eyes from direct sunlight.
Use the treatment recommended by the doctor for the recommended period.
Use moisturizing eye drops for at least 6 months for continuous eye hydration.
Visit the doctor periodically to check on the outcome of the operation and the stability of vision.
In the end, a cosmetic doctor is advised to choose the appropriate ophthalmologist with extensive experience in the types of vision correction operations, and to clarify what types of vision correction operations are completely different from eye plastic surgery, and to discuss with him all possibilities and complications as well, to be assured of the outcome of the operation and to go through it without fear or anxiety.
