The patient receives local anesthesia through numbing eye drops before the procedure. The surgeon then creates a very thin, partial flap on the cornea and folds it back to expose the underlying corneal tissue. An excimer laser is then used to reshape the corneal surface. After the reshaping is complete, the flap is carefully repositioned onto the cornea

In this procedure, the surgeon treats the cornea by evaporating the outermost layer of the cornea before using an excimer laser to reshape its curvature. Doctors opt for this type of vision correction surgery for patients with thin corneas, athletes exposed to direct eye trauma, and individuals suffering from severe dry eye. This approach helps maintain the strength and integrity of the cornea.

The recovery period typically takes 5 to 7 days for the removed layer to regenerate. Patients may experience a burning sensation in the eyes following the procedure.

• Patients who experience vision regression after a previous vision correction surgery.
• Individuals with high refractive errors, to prevent corneal weakening.
• Women in their twenties, especially during pregnancy, childbirth, or other hormonal changes.
• Those with early-stage keratoconus (corneal thinning disorder).

Before undergoing vision correction surgery, your ophthalmologist will review your general medical history and any medications you are taking to determine whether you are a suitable candidate. A comprehensive eye examination will then be conducted to ensure your eyes are healthy enough for the procedure. This examination includes:

• Evaluating refractive errors (nearsightedness, farsightedness, and astigmatism)
• Assessing corneal shape and thickness
• Performing a corneal topography (eye fingerprint scan)
• Examining the retina and optic nerve

• Discontinue contact lenses for a period recommended by your doctor (typically 3 to 14 days) before both the eye exam and the procedure, as contact lenses can temporarily alter the natural shape of the cornea.
• Avoid wearing eye makeup for at least 24 hours before the surgery and on the day of the procedure.

• Immediately after the procedure, your doctor will allow you some time to rest. You may experience a temporary burning or itching sensation. Since driving is not recommended after the surgery, you will need someone to assist you on your way home.

  You should expect blurred or hazy vision right after the procedure, but it will gradually improve over the following days. In rare cases, full recovery may take a bit longer. Most patients notice immediate improvement in their vision after treatment.

  Post-Surgery Care:

  • Rest for at least two days after the procedure.
  • Avoid intense physical activities for at least one week.
  • Do not rub your eyes to prevent complications.
  • Limit sun exposure as per your doctor’s recommendation.
  • Strictly follow your doctor’s instructions and use prescribed eye drops as directed.

• The likelihood of permanent results increases if the surgery is performed after the age of 18. However, patients should be aware that if vision regression occurs, a follow-up correction procedure may be possible after the necessary examinations.

  Although vision correction surgeries have an excellent safety record, complications can arise if post-operative care and instructions are not properly followed.

  It is also important to note that around the age of 40, most people will still require reading glasses due to presbyopia, a natural age-related decline in near vision.
