Myopia LASER

Eye Center

LASER correction of myopia, hyperopia, and astigmatism

Refractive surgery encompasses all surgical techniques and procedures that help correct refractive errors such as myopia, hyperopia, and astigmatism.

The use of the excimer laser (Myopia Laser) has been studied and applied since 1985. The continuously evolving clinical experience and expertise from its applications have elevated photorefractive surgery to the top of effectiveness for correcting refractive errors.

These innovative surgical procedures are characterized by absolute safety, reliable results, and numerous benefits for the patient, such as comfort and freedom of movement, improved quality of life, and independence from glasses and contact lenses.

Indications – Candidate Requirements

Suitable candidates for refractive surgical procedures are:

  • Individuals who have reached 18 years of age.
  • Patients whose myopia does not exceed 10 diopters and whose hyperopia and astigmatism do not exceed 6 diopters.
  • Patients with stable vision for the past year (2 consecutive measurements).
  • Patients who, due to professional reasons, cannot wear glasses or contact lenses (e.g., police officers, military personnel, and other security forces).
  • Those involved in sports where wearing glasses affects performance.
  • Patients who experience problems with contact lenses (intolerance, allergies).
  • Those who do not wish to use glasses for aesthetic reasons.

Contraindications

Some factors may prevent the application of refractive surgery in certain patients. These include:

  • Patients with certain eye conditions such as glaucoma, keratoconus, or other corneal and retinal diseases.
  • Patients who are breastfeeding, pregnant, or planning to become pregnant.
  • Patients with severe dry eye.
  • Viral infections such as herpes simplex or herpes zoster.
  • Patients with unregulated autoimmune diseases, such as diabetes.
  • Patients with very thin corneas.

Refractive Surgery Methods

The two most common techniques in refractive surgery are femtoLASIK (Femtosecond Laser-assisted In Situ Keratomileusis) and PRK (Photorefractive Keratectomy). Both techniques use the SAME excimer laser to sculpt and reshape the corneal surface.

  • During femtoLASIK, a flap is created, and then the excimer laser sculpts the corneal layer. After reshaping, the flap is repositioned.
  • In PRK, the surgeon removes the corneal epithelium and then sculpts the cornea with the laser. In recent years, epithelial removal can be performed with the laser itself (transPRK) rather than manually or with alcohol as in the past. After laser treatment, a therapeutic contact lens is placed until the epithelium regenerates (3–7 days).

The main advantage of femtoLASIK is immediate vision restoration and rapid recovery with minimal discomfort. Patients can return to daily activities within a few days.
PRK and transPRK require a longer recovery period. Patients may experience mild photophobia and foreign body sensation during the first 24 hours, and vision reaches the desired level in 2–3 weeks.

The Procedure
Preoperative Examination

Both techniques require a thorough preoperative evaluation. Patients must stop using contact lenses for 2 weeks before the examination.

  • Initially, a refraction test is performed (measurement of exact prescription), often with cycloplegic drops to avoid refractive errors.
  • Topography is essential to provide a detailed corneal map, determine the most suitable technique, and eliminate the risk of complications.
 
Preparation for Surgery

On the day of surgery, patients should:

  • Be well-rested
  • Eat a light meal (e.g., toast)
  • Wear light, comfortable clothing
  • Arrive at the clinic on time
  • Be accompanied by someone
  • Have patience
  • Bring a pair of sunglasses
  • Avoid perfumes or sprays (hair, body)
  • Avoid makeup
  • Avoid applying creams around the eyes

 

Upon arrival, nursing staff will repeat some examinations and prepare the eyes with anesthetic drops. Surgical clothing is provided, and the patient is escorted to the operating room.

A mild sedative may also be given to reduce anxiety.

Postoperative Care
  • Rest for at least two days and avoid all work
  • Keep eyes closed as much as possible
  • Follow all postoperative instructions from your doctor
  • Wear sunglasses outdoors
  • Use artificial tears frequently
  • Wear the protective eye shield provided by the clinic every night for about a week
  • Avoid exercise and swimming for the first 20 days
  • Keep water and shampoo away from the eyes
  • Do not rub the eyes
  • Avoid driving until vision is fully restored
 

Frequently Asked Questions

You are a suitable candidate for LASER if:

  • You are 19 years or older and your prescription has been stable in recent measurements by your ophthalmologist.

  • You do not have glaucoma, cataract, keratoconus, or other known eye conditions.

  • You have not had viral keratitis (e.g., herpes simplex) in the past.

  • You have no corneal scars (e.g., old injuries).

  • You have no unregulated systemic diseases such as diabetes or hypertension.

  • You have no active eye inflammation such as conjunctivitis or anterior uveitis.

Candidates must first undergo a detailed refraction measurement (prescription) and a general eye exam. Cycloplegic drops are used, which temporarily blur vision for about 10 hours.
The next step is a preoperative corneal topography. This provides essential information about corneal curvature, thickness, and assist us in understanding if the eye meets all requirements for a safe procedure.
Corneal pachymetry is also performed, providing crucial data for selecting the most appropriate technique (LASIK, PRK, etc.).

PRK is the less invasive and non-flap procedure, which is its main advantage.
The cornea remains intact, and correction of myopia, hyperopia or astigmatism is achieved without creating a flap.

The main disadvantage compared to LASIK is mild discomfort and photophobia for the first 24–48 hours due to slower healing by comparison, which delays final vision restoration.
Yet, patients who select this method are fully functional within 7–10 days.
In LASIK, vision recovery is faster. The refractive error is corrected by sculpting the cornea beneath a flap.
This method is more invasive, and theoretically, complications are statistically more frequent.

Shortly before the procedure, after the preoperative exam (if done the same day), preparation begins. A mild sedative may be given to reduce anxiety and ensure smooth cooperation with the surgeon.

The main anesthesia is topical (eye drops), and the patient does not feel discomfort or pain.

Duration depends on whether PRK or LASIK is performed.
PRK lasts 5–60 seconds, depending on the correction required, not including preparation and antisepsis.

The LASIK technique takes an additional 6–7 minutes. This is due to the need to create the flap by means of special equipment (femto laser or microkeratome). After creation of the flap, the remainder of the procedure is identical to PRK.

Studies of millions of surgeries performed globally show that complications are rare and can be further minimized with a thorough preoperative evaluation.

Serious potential complications include:

Infection:

Infections are extremely rare due to aseptic conditions during surgery and the administration of preventive antibiotic drops.

Haze:

Rarely, especially if postoperative care is interrupted, there may be corneal haze.

It is sually asymptomatic, does not affect vision, and resolves within a year.

This haze is related to the LASER thermal phenomenon and responds well to corticosteroid eye drops.

In the rare cases when it affects vision, haze can be treated with LASER.

Under- or over-correction:

Sometimes, undercorrection or overcorrection may occur. Under-correction can be addressed with additional laser treatment.

In the case of over-correction, this may be managed with topical treatment during recovery.

Immediately after surgery, vision may be blurred.

Patients may find bright light, screens, or sunlight uncomfortable (especially on particularly sunny days).

A sandy sensation in the eyes may occur. These effects usually last the first 24–48 hours.
Patients should be accompanied postoperatively.

Driving should be avoided until vision allows (typically 24–48 hours).

After surgery, patients should avoid strong sunlight, especially initially. It is therefore recommended to avoid LASER in July and August. Under controlled conditions where sunlight exposure is minimized, this is not an absolute contraindication.
