Laser vision correction operations

They are operations in which the curvature of the cornea is controlled by a laser in a way that treats myopia, farsightedness and astigmatism, which ultimately leads to the formation of a clear image on the retina, and the complete dispensing of medical glasses and contact lenses.

What are the defects of vision?

• Myopia is the inability of the eye to see distant objects clearly.

• Farsightedness: It is the inability of the eye to see near and far objects without eye fatigue.

• Astigmatism: Astigmatism occurs as a result of irregularities in the surface of the cornea of the eye, which leads to headache and blurred vision.

How can vision defects be corrected?

• Lasers: all kinds (regular, femtolysk, castm lasik, surface laser, femtosil).

In all of them, the curvature of the cornea is controlled in a way that addresses myopia, farsightedness and astigmatism with great effectiveness. LASIK is not a surgical procedure. Rather, it is a laser correction of corneal curvature in a few seconds, and its effect lasts for life in most cases.

• Lens implantation (ICL):

It has witnessed a great development in recent years, especially after the emergence of the last generation of lenses implanted in the posterior chamber of the eye, which increased the degree of safety and effectiveness of the operation by nearly 100% and made the operation the ideal solution for patients who suffer from weak cornea or severe nearsightedness.

• The latest laser vision correction procedures

1- Regular LASIK.

2- Detailed LASIK.

3- Femto-Lysic.

4- Femto-custom lasik.

5- Femto Smile.

How is the patient prepared before LASIK?

• Before LASIK, the doctor examines the eye in detail to determine the following with the utmost accuracy:

• Accurately know the degree of nearsightedness or farsightedness, and accurately determine the degree and axis of associated astigmatism.

• Ensure that the eye is free from diseases such as high eye pressure, cataracts, retinal diseases, and corneal clouds.

• Making a topographic drawing of the cornea with the pentagonal camera, which imaging the topography of both the front and back surfaces of the cornea and determining the thickness of the cornea with the utmost accuracy, then after that the image is analyzed by computer to find out the regularity of the corneal surfaces and make sure that they are free of keratoconus.

• Creating a map of the visual distortions of the eye and taking an eye print using a technology that identifies the problems that the optical system of the eye suffers from, which leads to a lack of efficiency of night vision even using glasses, then the computer attached to the LASIK device is fed with the necessary data in order to detail LASIK taking into account the treatment of these problems, This is called detailed LASIK or Alcastum LASIK.

What steps take place inside the operating room and the time taken?

• The operation does not take more than 5 minutes, the operation is performed under the influence of local anesthesia, and the patient does not feel any pain during the operation, and then feels a slight burning sensation for a period of 2 - 6 hours.

• All that is required of the patient is not to move and respond to some of the instructions that the doctor gives him during the operation, then the patient moves to the waiting room until the doctor examines him again and the patient returns home.
