Myopia surgery: Myopia Correction Methods
Currently, there are safe and effective myopia correction methods; the thousands of cases operated with published results provide scientific evidence in favor of these techniques. All of them are performed on an outpatient basis, that is, without admission and through eyedrop anesthesia. It is a painless surgery and allows you to lead a normal life quickly
What types of treatments for myopia are there?
Currently there are four methods to correct myopia defects, they can also correct astigmatism and farsightedness. The ophthalmologist recommends the most appropriate technique according to each particular case, considering the number of diopters and the characteristics of the eyes.
PhotoRefractive Keratectomy is considered the best technique for low graduations. It is an Excimer Laser treatment on the corneal surface without the need to make a cut on the cornea. It is the least invasive treatment for the correction of myopia. It produces discomfort and blurred vision the first days due to the superficiality of the treatment, so a contact lens is put on for a week.
Femto – LASIK
The LASIK technique (Laser Assisted in SItu Keratomileusis) performs the same Excimer Laser treatment as the PRK but on a deeper level. This way vision is recovered faster, but to do this you need to make a cut in the cornea. That cut was made with a blade (Microkeratome) in the traditional LASIK technique but currently it is done with Femtosecond Laser, so it is a 100% Laser treatment and is called Femto-LASIK.
It is the newest technique, Small Incision Lenticule Extraction makes a treatment in the depth of the cornea by Femtosecond Laser. The LASIK cut is not required, but through a minimal incision the surgeon removes the tissue carved by the laser to neutralize the diopters of myopia or astigmatism. By altering the corneal surface less, it also alters the sensation of dry eye less and vision recovers earlier.
The intraocular lenses ICL (Intraocular Collamer Lens) are flexible and are inserted into the eye to correct myopia, astigmatism and hyperopia without using the laser or altering the cornea. They have advantages in cases of higher diopters, fine or irregular corneas and are also reversible. From 6 diopters, it is the technique that provides the best visual quality.
Furthermore, these techniques can treat astigmatism and farsightedness in a similar way; combining treatment according to the patient. Make an appointment for the preoperative study and you will have the opportunity to solve all your doubts as well as listen to the ophthalmologist’s recommendations for your particular case.
Frequently asked questions about myopia surgery:
What is refractive surgery?
It is a method to correct or improve vision loss related to myopia, astigmatism and hyperopia and avoid the use of glasses or contact lenses.
Is myopia surgery painful?
No, since a local anesthetic eye drop is applied and it is not bothersome. There may be discomfort in the immediate postoperative period, depending on the technique. Dry eye sensation is also observed, which in most cases remits within the first month.
Do I have to request sick leave?
It depends on the postoperative period and the patient. It is usually an outpatient surgery, so you are discharged the same day. Vision gradually recovers and can be incorporated into your work depending on visual needs. There is a ban on driving for a month after having your eyes intervened.
Will I be able to lead a normal life?
It depends on the technique used, but generally, you can return to the routine normally. In PRK surgery cases, it has a slower healing, which implies a more progressive return to routine.
How long does myopia surgery last?
This type of intervention is quite fast, lasting approximately 10 minutes for both eyes. It depends a lot on the collaboration of the patient, but our experience is quite good in this regard.
With what maximum diopter can I operate?
Currently we have techniques to correct the dioptres according to the quantity individually. The PRK is recommended for myopia and low astigmatism, the Femto-LASIK for hyperopia and high astigmatism, the SMILE for myopia up to 7 diopters and the ICL lenses for cases of higher diopters or thin and irregular corneas that do not recommend laser treatments.
What is the proper age to undergo myopia?
The minimum age is 18 years; but the most important thing is that the graduation has been stable for at least one year and that the relevant ophthalmological tests have been done. In our case we evaluated the ocular surface, the corneal topography and the interior of the eye in addition to the graduation to be able to make the best recommendation.
What precautions and cares should I have after myopia surgery?
The most recommended is:
- Avoid dry environments.
- Use the eye drops prescribed by your ophthalmologist.
- Avoid friction in the eyes.
- Wear sunglasses that guarantee eye protection.
- Try not to strain your eyes during the days after surgery.
What risks and complications are there?
The most common risks and complications are dry eyes and inflammation after surgery. In some cases, the visual quality may not be perfect and residual diopters may persist. Rarely, an infection or a particular complication of each technique may occur. However, it is one of the interventions with the highest safety and efficacy index globally.
What type of anesthesia is used?
The anesthesia used for this type of intervention is in drops and may be associated with a slight sedation in case the patient is nervous. Everything is personalized to ensure the best possible experience.
Can myopia come back, even if I had surgery?
There is the possibility of residual diopters or a slight regression over time. In this case, the option of retouching using LASIK can be considered.
