Refractive surgery in Valencia


SUPRACOR is a presbyopia treatment in which Excimer laser is used to treat both eyes. The latest technological advances and innovation have allowed adapting the well known and optimized LASIK technique, used since the beginning of the 90s, to reshape a “multifocal” cornea so that the patient is able to see at short, medium and long distances.

Until now, monovision technique, based on ocular dominance where one eye is corrected using Excimer laser for short-distance vision and the other one for long-distance vision so that the brain uses the information from one or the other depending on the visual focal distance, was the only available technique.

Thanks to SUPRACOR, it is now possible to treat both eyes enabling them to see at short and long distances using Excimer laser.

Preoperative examination

It is important not to wear contact lenses 3 to 21 days before the preoperative examination used to evaluate whether SUPRACOR is an adequate treatment for the patient is carried out, depending on the type of lenses and frequency of use, due to an effect known as corneal warpage which can difficult ophthalmological examination. The same criteria are applied for the days before surgery.

Frequently, antibiotics are prescribed to minimize infection risk after surgery. Sedatives may also be used 30 minutes before the intervention.

Treatment: how is the intervention carried out?

SUPRACOR technique can be divided into of 3 basic parts:


Step 1: Corneal flap creation

The first step of this technique is creating a corneal tissue flap which will be folded back into its original position after corneal remodeling.

To do this, a blepharostat is used to hold the eyelids apart and avoid involuntary blinking.

A suction ring is centered over the pupil to hold the eye still. The patient will feel a gentle pressure on his/her eye.

The flap can then be created in two ways:

  • Using a high precision surgical instrument known as microkeratome, part of the cornea is removed leaving its intermediate cell layer, called stroma, exposed so that laser can act on it.
  • Using femtosecond laser (femtoLASIK) which generates infrared light short pulses to create the corneal flap.

The corneal flap stays in contact with the rest of the cornea by one of its ends so it can be folded back into place afterwards.

Once the hinged flap is removed, the patient’s vision will become very blurry and he/she will only be capable of seeing halos.

Step 2: Laser correction

The second step of SUPRACOR technique for presbyopia treatment is the most important one. It involves using Excimer laser to reshape the corneal surface so that the patient is able to see at all distances.

A series of laser pulses precisely vaporize the previously programmed area of corneal tissue.

This part of the intervention only lasts for about 10 seconds and during this time, a security system known as “eye-tracking”, detects the eye’s movements 4000 times per second giving the laser greater precision and safety.

Step 3: Flap relocation

Once laser treatment has ended, the flap is folded back into its original position and the absence of foreign bodies and correct relocation are verified. The flap naturally adheres to the cornea without the need of stitches until it completely recovers. The ophthalmologist will put protective contact lenses which will be removed in the postoperative check-up days after.

Postoperative period

After surgery, antibiotic and anti-inflammatory eye drops are prescribed, as well as lubricant eye drops as the eye’s moisture is reduced for a couple of weeks.

Risks and complications

Presbyopia treatment using SUPRACOR technique has shown to be safe and effective and has been perfected over the years. This is why only a reduced number of patients experience vision problems, which can be satisfactorily resolved, after surgery.

These are the main postoperative complications which may arise from SUPRACOR procedure. Most of them can be resolved using medication within a short period of time after surgery, whilst others can be avoided by using Wavefront Laser technology or may need reoperation.
