What are the most recent vision correction procedures given the wide range of techniques and operations available? This article contains the solution.
Myopia, farsightedness, and astigmatism are all conditions that can affect the lens of the eye, 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
In these procedures, lasers are used to reshape the cornea so that light rays can focus on the retina. There are various kinds, such as:
- LASIK
In this procedure, the doctor modifies the cornea's shape with a laser.
In order to change the cornea's shape and correct the lens' refractive error, the doctor makes a tiny incision in the cornea and folds the outer tissue before shining a laser on the inner tissue.
LASIK is suitable for patients with nearsightedness, farsightedness, and astigmatism.
- SMILE Technology
One of the most recent methods for vision correction is SMILE technology, which the US Food and Drug Administration approved in 2016.
Using a femtosecond laser, the doctor separates the lens (lenticule), a small portion of the cornea, from the rest of the corneal tissue. Next, a tiny hole is made at the tip of the cornea, and a spatula is carefully inserted through the hole and rotated to ensure that the lens is completely separated before it is removed with forceps.
Patients who have nearsightedness should be able to have the procedure, which lasts no longer than 15 minutes.
- Sub-Bowman keratomileusis
This procedure uses a femtosecond laser to vaporise a thin layer of cornea beneath the Bowman's membrane, which is a modified version of the LASIK procedure.
Compared to surface keratotomy operations, this procedure is characterised by a reduction in postoperative pain and an improvement in vision.
- Laser Epithelial Keratomileusis
The doctor applies a solution to loosen the epithelial cells, then he forms a flap or layer of corneal tissue with a microsurgical instrument, moves it aside, uses a laser to reshape the cornea, moves the epithelial flap back into place, and fixes it with a contact lens to encourage epithelial healing.
- In situ laser epithelial keratomileusis (Epi-LASIK)
One of the most recent procedures for vision correction involves the use of an instrument called an epikeratome, a sharp blade used to remove epithelial cells, followed by the use of a laser to reshape the corneal tissue.
Compared to other operations, this one is characterised by less post-operative pain and less harm to the epithelial cells.
The latest vision correction operations: cataract surgery
Intraocular lens implant surgery and refractive lens replacement surgery are the two primary types of lens surgery. The lines that follow provide information about them:
- Phakic intraocular lens implantation
Patients who have severe refractive errors that are challenging to correct with corneal surgery are candidates for these procedures.
Patients can maintain their ability to focus on close objects because the intraocular lens is implanted in front of the eye's natural lens rather than removing it.
- Refractive Lens Exchange
This procedure treats cataracts by having the doctor insert an artificial lens in place of the eye's natural lens (eye lens).
Senior citizens who cannot tolerate laser surgery or who are developing cataracts should consider this procedure.
traditional vision correction procedures
Corneal refractive surgery (Photorefractive keratectomy).
One of the more traditional procedures for correcting vision, the doctor first uses a laser, a special blade, or alcohol to remove the outer layer of the cornea before reshaping it with a laser. This procedure is used to treat astigmatism, nearsightedness, and farsightedness. This operation is preferred if the patient has a thin cornea.
