Refractive surgery with the excimer laser aims to correct refractive errors such as myopia, astigmatism, hyperopia and presbyopia.

Two common techniques are PRK (photoreactive keratectomy) and LASIK (laser in situ keratomileusis).

PRK (PhotoRefractive Keratectomy):


- The surgeon removes a thin layer of cells from the corneal surface.
- The excimer laser "sculpts" the cornea to correct the refractive error.
- Healing times between 3 and 5 days.

LASIK (Laser-Assisted In Situ Keratomileusis):

- The surgeon, through the laser, creates a thin flap in the cornea, raises the flap to expose the internal corneal tissue.
- The excimer laser “sculpts” the underlying tissue.
- The flap is then repositioned.
- Healing is to be considered within a day with a blurred vision time of approximately 3 hours.

Both techniques aim to change the shape of the cornea to focus light correctly on the retina, thus improving vision.


The choice between PRK and LASIK depends on the patient's ocular characteristics and the surgeon's preferences.

The main difference between PRK and LASIK concerns the preparation of the cornea: PRK acts on the surface, while LASIK creates a flap.

Both procedures are considered safe and effective, but recovery times and specific details may vary.

These surgical techniques are generally effective in correcting myopia, astigmatism, hyperopia and, to a limited extent, presbyopia.

- Myopia: Refractive surgery reduces the curvature of the cornea to correct myopia, allowing light to focus on the retina rather than in front of it.

- Astigmatism: The irregular shape of the cornea in astigmatism can be corrected by removing excess corneal tissue or by strengthening thinner parts.

- Hyperopia: Surgery can increase the curvature of the cornea or change the shape of the eye to improve the focusing of light on the retina.

- Presbyopia: For presbyopia, in which the eye loses the ability to adjust focus at near, refractive techniques can be adapted through procedures such as LASIK “monovision” or the use of multifocal lenses.

The effectiveness of these procedures may vary from person to person, and not all people are ideal candidates for refractive surgery.

Consultation with an ophthalmologist surgeon who specializes in refractive surgery is essential to determine the procedure best suited to each individual.

Refractive surgery with phakic intraocular lens implantation is a procedure in which an artificial lens is inserted inside the eye, keeping the natural lens intact.

This technique is often used to correct myopia, astigmatism or hyperopia, especially when laser surgery is not the preferred choice, or is not possible.

Here's how it generally works:

1. Preparation:
- The ophthalmological surgeon evaluates the patient's suitability and determines the correct optical prescription.


2. Procedure:
- A small incision is made on the eye.
- A phakic intraocular lens, specifically designed to correct refractive error, is inserted.
- The lens is positioned in front or behind the iris, maintaining the natural lens of the eye.

3. Healing:
- Healing is often faster than with some laser procedures, and the patient may experience relatively quick visual improvement.

This approach is particularly useful when the ocular structure is not suitable for other forms of refractive surgery or when a more significant correction is needed.

Phakic intraocular lenses are custom designed to correct each patient's specific optical prescription.

It is a procedure that offers long-lasting results and can lead to a noticeable improvement in vision.

It is important to note that, as with any surgical procedure, there are risks and benefits that must be carefully weighed with your ophthalmologist surgeon during your pre-operative consultation.

The choice between laser surgery and phakic intraocular lenses depends on the patient's ocular characteristics and the surgeon's preferences.




Refractive surgery with multifocal intraocular lens implantation is a procedure in which special lenses are inserted into the eye to correct more than one type of vision defect, often aiming to improve both near and distance vision.


This approach is mainly used to treat myopia, astigmatism and hyperopia.


Here's how the procedure usually goes:


1. Evaluation:

- The ophthalmologic surgeon evaluates the patient's optical prescription and determines suitability for multifocal intraocular lenses.


2. Procedure:

- A small incision is made in the eye.

- The multifocal intraocular lens is inserted to replace or complement the natural lens of the eye.

- These lenses are designed to provide visual clarity both near and far.


3. Adaptation:

- The patient may require a short adjustment period to get used to the new vision, especially if it is the first time using multifocal lenses.


This procedure is particularly suitable for those who wish to reduce or eliminate their dependence on glasses for reading and daily activities.


As with any surgical procedure, it is important to discuss the specific risks and benefits, as well as realistic expectations regarding results, with your ophthalmologic surgeon.



Myopia is a vision disorder typical of an eye with a higher than normal axial length (22.5mm) or an excessive curvature of the cornea, which causes light rays to focus on a point anterior to the retina rather than directly on it. it, making the image blurry.

Myopia is defined as mild when less than or equal to 3 diopters, moderate between 3 and 6 diopters, high (or degenerative) when greater than 6 diopters or when the eye is longer than 26.5 mm (when normal is around 22.5 mm) .
Myopia can be treated with refractive surgery to help the patient see without glasses. The surgical technique must be adapted to the level of myopia to be eliminated.

High myopia presents an increased risk of peripheral retinal detachment, macular retinal detachment, neovascular maculopathy (hemorrhages and neovascular membranes), atrophy (lack of tissue).

Vitreoretinal surgery can be used to treat some of the complications associated with high myopia, such as retinal detachment.

The specific treatment will depend on the individual characteristics and needs of each patient, and should be evaluated by an ophthalmologist specializing in vitreoretinal surgery.
