Laser vision correction

Laser vision correction

Dnipropetrovsk Regional Clinical Ophthalmological Hospital invites all residents of the city of Dnipro and the Dnipropetrovsk region to improve their vision with the help of laser vision correction.

Laser vision correction today is the most safe and effective method of correcting astigmatism (up to ± 3,0 D), farsightedness (up to +4,0 D), myopia (up to -16,0 D) and other diseases. Laser correction not only improves vision, but also makes it possible to get rid of the need to wear glasses and contact lenses. At the moment, the most popular in the world are LASIK and LASEK techniques.

What is LASIK?

LASIK (laser keratomileus) is a combination of microsurgical intervention and excimer laser technology. During the laser correction, a special device - a microkeratome is used, which previously creates a flap of corneal tissue that bends, and laser action is already made on the inner layers of the cornea. After laser correction, vision improves due to the fact that the laser creates a new shape of the cornea - the "natural lens" of our eye, so that it begins to refract light rays differently, they focus on the retina and the image becomes clear.

 



Benefits

  • Compared with LASEK, the postoperative period is more comfortable.
  • Absence of risk of corneal opacification in comparison with other methods.
  • Improved vision is already on the day of surgery.
  • Lack of significant restrictions on visual loads after surgery.
  • Allows surgery on both eyes in one day.

Postoperative period

Within some time after the LASIK surgery, you are prone to experience minor discomfort: foreign body sensation, lacrimation, photophobia.

Soon all the unpleasant feelings will pass without a trace. A marked improvement in visual acuity occurs on the day of surgery. Significant restrictions on physical and visual loads after LASIK are absent. Immediately after the operation, you will be able to return home.

Limits of laser vision correction using the LASIK method

  • myopia up to -15.0D

(the doctor considers the individual features of the eye);

  • Farsightedness up to + 6,0D;
  • Astigmatism up to ± 3.0D.

Contraindications to LASIK

Relative:

  1. Cataract, glaucoma, keratoconus (thinning of the cornea).
  2. Monocularity (single eye).
  3. Severe vascular diseases of the body.
  4. Collagenoses, arthritis, diabetes mellitus, systemic diseases that affect the healing process.
  5. Presbyopia (age-long farsightedness, which appears in all people after 45-50 years, due to the fact that the lens loses its elasticity and is not able to change its curvature when looking at a closely located object, that is, the lens property - accommodation is lost).
  6. Operated retinal detachment.
  7. Immune Deficiency Conditions.

Absolute:

  1. Age to 18 years (it is believed that the growth of the body, including the eyes, lasts until 18 years, that is, the vision can still change).
  2. Progression of refractive changes (it is impossible to predict the result).
  3. Inflammatory diseases of the eyes or the whole body.
  4. Spasm of accommodation (muscle spasms of the lens, resulting in "false" myopia).
  5. Pregnancy, lactation period (hormonal changes).
  6. Changes in the retina which require preventive laser coagulation

 

WHAT IS LASEK?

LASEK is laser epithelial keratomileusis. The use of LASEK completely excludes the possibility of keratoconus development, since the operation is performed on the surface layer of the cornea. During the LASIK surgery all epithelium and a quarter of a layer of a stroma is lifted, during the LASEK only the epithelium is lifted. Since more corneal tissue is retained here, this method is used in cases where the cornea is excessively refined and LASIK is not applicable. The difference from PRK is that during the PRK the epithelium is completely removed, but during the LASEK surgery it remains. Therefore LASEK is less painful and the process of recovery after it lasts faster. In addition, unlike the LASIK, the LASEK technology excludes damage to the inner layers of the cornea, in particular to its stroma.

Benefits

  • Exclusion of damage to the deep layers of the cornea, in particular to its stroma.
  • Preservation of anatomy of corneal layers.
  • The possibility of correcting myopia, hyperopia and astigmatism in cases when correction by the LASIK method is contraindicated.
  • Correction can be conducted with stabilized keratoconus, a thin cornea, peripheral degeneration of the retina.

Postoperative period

After the LASEK surgery painful sensations, discomfort, lacrimation, photophobia can occur during the day. You will feel improvement of vision on the next day, a significant improvement - after removal of contact lenses. Full stabilization begins by the end of the first month.

Limits of laser correction using the LASEK technique

  • Myopia up to - 8 D.
  • Farsightedness up to +4 D.
  • Astigmatism up to 4 D.
