to know them
There are many procedures and operations to correct vision, so what are the latest vision correction operations? Find out the answer in this article. There are different problems and disorders that affect the lens of the eye and cause short sightedness, farsightedness, or astigmatism, but there are many operations to correct vision that help focus light rays on the retina.

Learn with us in this article about the latest vision correction operations
The most recent refractive surgery: laser eye surgery
Lasers are used in these operations to reshape the cornea so that it can focus light rays on the retina. There are several types, including:
LASIK
In this process, the doctor uses a laser to change the shape of the cornea.
The doctor makes a small incision in the cornea and folds the outer tissue, then shines a laser on the inner tissue of the cornea, where the doctor changes the shape of the cornea in order to correct the refractive error of the lens.
LASIK is suitable for patients with nearsightedness, farsightedness, and astigmatism.
SMILE Technology
SMILE technology is one of the latest vision correction procedures, as it was approved by the US Health and Drug Administration in 2016.
The doctor separates a small part of the cornea called the lens (lenticule) from the rest of the corneal tissue using a femtosecond laser, then makes a small hole at the tip of the cornea, then a spatula is ed through the hole and it is carefully rotated to ensure that the lens is completely separated before it is removed with forceps.
The operation does not take more than 15 minutes, and this operation is suitable for patients who suffer from nearsightedness.
Sub-Bowman keratomileusis
This procedure is a modified version of the LASIK process, in which a femtosecond laser s a thin layer of the cornea under the Bowman''s membrane. This procedure is a cross between LASIK and surface keratotomy operations.
This operation is characterized by a decrease in pain intensity and an improvement in vision in the postoperative period compared to surface keratotomy operations.
Laser Epithelial Keratomileusis
The doctor uses a solution to loosen the epithelial cells, then uses a microsurgical instrument to form a flap or a layer of corneal tissue that he moves aside, then uses a laser to reshape the cornea, then the epithelial flap is repositioned and fixed using a contact lens to promote epithelial healing.
In situ laser epithelial keratomileusis (Epi-LASIK)
This operation is one of the latest vision correction operations, where a tool called (Epikeratome) is used, which is a sharp blade used to remove epithelial cells, then the doctor uses a laser to reshape the corneal tissue to correct vision.
This operation is characterized by less pain after surgery compared to other operations, and it also causes less damage to the epithelial cells.
The latest vision correction operations: cataract surgery
There are two main types of lens surgery: intraocular lens implant surgery and refractive lens replacement surgery. Details about them are in the following lines:
Phakic intraocular lens implantation
These operations are used for patients with severe refractive errors that are difficult to deal with by corneal surgery.
The intraocular lens is implanted in front of the eye''s natural lens, and the eye''s natural lens is not removed, so patients can retain their ability to focus on close places.
Refractive Lens Exchange
In this process, the doctor replaces the eye''s natural lens with an artificial lens, and this process is used to treat cataracts (eye lens).
This operation is suitable for elderly patients who cannot tolerate laser operations, or who have the beginnings of cataracts.
traditional vision correction procedures
Corneal refractive surgery (Photorefractive keratectomy).
This operation is one of the old operations in correcting vision, as the doctor removes the outer part of the cornea with a laser or a specific blade or using alcohol, then uses the laser to reshape the cornea. This procedure is used to correct nearsightedness, farsightedness, or astigmatism. This operation is preferred if the patient has a thin cornea.
