Refractive surgery

Refractive surgery . Refractive surgery is a set of surgical procedures that modify the anatomy of the eye , especially the cornea , definitively eliminating the refractive defects of myopia , hyperopia and astigmatism so that the use of glasses or contact lenses is not necessary . There are numerous techniques such as excimer laser , phakic lenses , astigmatic incisions , or intraocular lenses .

Requirements

Not every patient is in a position to have refractive surgery. Below are those that are not suitable for the same to be done.

  • Pregnancy , lactation, use of hormones .
  • Diabetic patients
  • Autoimmune diseases ( Systemic Lupus Erythematosus , rheumatoid arthritis , etc.)
  • Autoimmune patients or with medication therapy that alters healing.
  • Systemic infections ( HIV )
  • Psychiatric , epileptic disorders .
  • Progressive or unstable myopia greater than 0.5 in a year.
  • Monocularity (single eye)
  • Previous corneal pathologies (eg: herpes simplex, zoster , keratoconus , scars, pannus, pterygium , etc.)
  • Glaucoma
  • Cataract (especially in people over 50)
  • Retinal pathologies (retinal detachments, vitrectomy, macular degeneration, retinitis pigmentosa)
  • Hypertensive patients must be compensated for their disease.

Preoperative method

For laser refractive surgery, the patient must be in the hospital where it is performed on the day previously indicated by the institute. On the indicated day, the patient should not use perfume , makeup , or hair gel. You should not wear large hair clips or jewelry .

From the day before surgery, you should use an antibiotic eye drop prescribed in the consultation (it may vary according to the rules of the institute but is generally belpartex) 1 drop every four hours all day in the eye to be operated on.

Both eyes are operated on the same day with few exceptions. The surgery is generally quick and painless but after it, at home, pain and / or discomfort may appear, for which you can use an analgesic ( metamizole , paracetamol , ibuprofen, etc.)

If you use medications to treat other conditions, you should continue to use them as usual.

The patient should follow the following instructions starting 4 hours after surgery:

  • Belpartex 1 drop every four hours
  • Hypomelous 1 drop every 6 hours
  • Artificial tears eye drops l drop every 2 hours

Generally, the day after the operation date, you must attend the eye center where you underwent surgery in order to carry out the first check-up by your surgeon.
