6 Options and Types of Vision Correction Surgery
1. PRK (Photorefractive Keratectomy)
PRK is a vision correction technology that uses a laser called Excimer Laser that is projected directly onto the cornea without having to cut the corneal surface first. Instead, it simply peels off the corneal surface. There are both methods of using medication to peel off the corneal surface or using the current technology that uses a laser to peel off the corneal surface, call TransPRK.
The advantage of this treatment method is that the cornea is a single piece with no seams, making it very strong. It is suitable for people with thin corneas or people in occupations that may be at risk of impact to the eyes, such as athletes or soldiers. The limitation of this method is that eye irritation is higher than other methods, so it is necessary to rest your eyes for the first 3-5 days after treatment.
2. LASIK (Laser-Assisted In Situ Keratomileusis)
This is also a vision treatment using Excimer laser, but a blade is used to open the top layer of the cornea and shoot the laser inside the cornea. After that, the corneal layer will be closed back into place. This method has the advantages of fast recovery and less eye irritation. However, it is necessary to avoid bumping or rubbing the eyes during the first month. Dry eyes may occur more often, which can be corrected by frequently using artificial tears, which will make the eyes more comfortable.
3. Femto-Lasik
Femto-Lasik is a new type of LASIK surgery. That uses a laser call a Femtosecond laser to open the corneal surface layer. It is more precise and safer than using a blade, with a fast recovery and less eye irritation. General care uses the same principles as regular LASIK.
4. ReLex (Refractive Lenticule Extraction)
It is the use of a Femto second laser to cut the cornea and drill small holes to remove the calculate corneal tissue. Which will improve vision. This method has the advantages of a small wound size, minimal eye irritation, and high corneal strength. However, you may see a little scattered light at first, and it will gradually improve.
5. Phakic IOL (Phakic intraocular lens)
It is a method of treating eyesight by inserting additional lens into the space between the cornea and the natural lens of the eye to adjust the refractive power, resulting in better vision, such as ICL, IPCL lenses, etc. This method has the advantage of being able to correct very nearsightedness (>10 diopters), which is still a limitation of traditional LASIK vision treatment. However, it is necessary to examine the structure of the eyes in detail. Especially the eyeball space where the lens insert wide enough for safety as well.
6. Refractive Lens Surgery (RLS)
Refractive Lens Surgery (RLS) is a surgical ยูฟ่าเบท https://ufabet999.app procedure to remove the natural lens. That is the cause of refractive problems and replace it with a new artificial lens. It uses computer technology to calculate vision values and produce a personalized artificial lens. That can correct nearsightedness, astigmatism, and farsightedness. The surgery takes approximately 10-15 minutes, and only 1 day after the lens replacement surgery, vision can improve.
