The ophthalmologist will perform a general eye exam through a series of tests that assess your eye health, your visual acuity, and the way your eyes refract light, to define the treatment to follow so that you can have clearer vision and make no effort focusing your eyes.
Astigmatism is usually treated with the use of corrective lenses or refractive surgery.
- Framed glasses: they are designed to compensate for the irregular shape of the eye, allowing the correct refraction of light.
- Contact lenses: for people who prefer them, it is an excellent alternative due to the great variety: soft, rigid, disposable, long-term use, bifocals, among others.
If you are a candidate for this procedure, the shape of your cornea will be surgically fixed so that you do not need to wear glasses or contact lenses.
There are several types of refractive surgery. Some of them are:
- LASIK (laser-assisted in situ keratomileusis): This is the most common procedure to flatten the cornea using a laser.
- LASEK (Laser-Assisted Subepithelial Keratectomy): A computer-guided excimer laser is used to reshape the cornea’s curvature.
- PRK (photorefractive keratectomy): the epithelium is removed using an excimer laser, allowing the cornea to adapt to the new shape.
- Epi-LASIK: Recommended for people who are not candidates for conventional LASIK.
- SMILE (Small Incision Lenticular Extraction): Using a laser, a small lens is created with tissue inside the cornea, to be removed later through a small incision.
There are other types of refractive surgeries that consist of the use of implantable contact lenses.
Potential risks of refractive surgery:
- Scar tissue on the cornea.
- Altered vision with halos or lights.
- Eye dryness.
- Visual problems.
