Lasik Astigmatism

title

Standard LASIK (Laser In Situ Keratomileusis)

lasik astigmatism excimer tunisia price cheap priceLasik has 2 stages:
 The cutting of a thin corneal flap.
 Then the action of the excimer laser.

 Cutting of a superficial corneal flap or "hood" (100 to 160 microns thick).
 Using a micro plane (microkeratome), which cups the eye.
 This “hood” attached to the cornea by a hinge will be lifted.

 The corneal stroma being exposed, the excimer laser can be applied.
 Then the flap put back in place without sutures adheres in a few minutes.
 Most often both eyes are treated in the same session in 30 minutes.

Before the operation

A complete ophthalmological examination is essential before any refractive surgery.
 Profession, age, pregnancy (wait 3 months after giving birth).
 Clinical signs: dry eye, Roaccutane treatment, herpes, glaucoma, diabetes, pregnancy, inflammatory and immune diseases , visual impairment in one eye (amblyopia).
 Sight measurements and optical corrections: a stable visual defect is essential.
 Examination under the microscope: cornea, lenses, retina, pupil size.
 Eye pressure measurement.
 Corneal topography (Orbscan): determines the shape and thickness of the cornea, detects keratoconus.
 ORA tests corneal elasticity.
 The OPD detects high degree optical aberrations (HOA).
Remove your contact lenses before preoperative examinations and before surgery:
 Flexible: 3 to 8 days.
 Stiff: 1 to 3 weeks.

During the operation of lasik astigmatism

The surgical act is fast (30min for the 2 eyes). The anesthesia is local by a few drops of anesthetic. Sometimes a relaxing premedication is necessary. The patient is lying on the operating table located under the laser, the head is positioned horizontally. The surgeon brushes the eyelids with an antiseptic product (notify me of any allergy to IODE), then sets up a plastic operating drape on the region of the operated eye. The unoperated eye is hidden by an ocular disc. An eyelid maintainer is used to keep the eye open and to prevent it from blinking. For PKR: the peeling of the cornea will be carried out painlessly. For Lasik or Intralase laser:
 Preparation of the corneal flap: A suction ring will exert a slight pressure on the eye to block it, then the flap is cut out (Microkeratome or Intralase). The fixation light disappears for a few seconds and returns as soon as the suction ring is removed, the corneal flap can then be lifted.
 The Excimer Laser is then activated: The patient is asked to quietly stare at a flashing red fixation light. The cut lamella, held by its hinge, is placed outside the field of the laser and the laser treatment can begin in the depth of the corneal laminae. The laser application time varies according to the defect to be treated (longer for strong myopia and hypermetropia). This phase is painless, the patient hears a crackle corresponding to the impact of the laser on the cornea. Do not worry if the eye moves and it no longer fixes this red light, the laser stops automatically (eye tracker active).
The laser procedure being completed, the lamella is repositioned.
In PKR a dressing lens is put in place for a few days. A few drops of antibiotic are instilled.
Currently in lasik the treatment is most often bilateral and simultaneous (both eyes at the same time). Its advantages: reduction of stress, less movement and absence of optical shift between the 2 eyes.

After the lasik operation astigmatism

The patient stays in the rest room for 15min then goes home, usually accompanied without shell or dressing, with protective sun glasses. A local treatment is prescribed for at least 8 days. A complementary treatment will be prescribed then. For 3 to 4 hours after the intervention, the eye is uncomfortable (tearing, sensation of burning, blurred vision, discomfort in the light). In case of pain, especially after PKR, an analgesic can be taken as soon as you return home, treatment with antibiotic and anti-inflammatory eye drops should be started. not rub your eyes for a few days after the operation.

Can you have myopia and astigmatism surgery at the same time?

Yes. aberrometriques).

Pregnancy and excimer laser?

Pregnancy is a contraindication due to the rare possibility of vision changes during this period. Wait 3 months after delivery.

Is the lasik operation painful?

No. The lasik operation is not painful, but sometimes unpleasant: tingling sensation, tickling or light pressure on the eye.

Excimer laser in Tunisia: local or general anesthesia?

The anesthesia is local by numbing drops. No general anesthesia because your attention is necessary to fix the laser light, so that the treatment is perfectly centered.

You see blurry and distorted - Astigmatism -

You are considering an operation for astigmatism, which technique to choose? You are astigmatic and sometimes more short-sighted, presbyopic or far-sighted. Depending on your age, your profession, does your degree of astigmatism allow this surgery?
The pre-operative examinations will give you precise and adapted information:
 FemtoLasik 100% laser with 4D active eye tracker and iris recognition (cornea surgery)
 Relaxing Limbic Corneal Incisions (Non-Puncture Corneal Surgery)
 Lens implant by ultrasonic procedure (intraocular surgery)
The operation of astigmatism will bring you a very great improvement in the quality of life and better visual comfort.

When can we swim?

After 3 weeks.

When can I smoke after the operation?

Avoid smoking in an enclosed area due to dryness and irritation induced during eight days.
