Excimer Laser

What is Excimer Laser?

Excimer laser is a laser device used to treat refractive defects in ophthalmology. Refractive defects such as myopia, hyperopia or astigmatism can be corrected using this technology.

Excimer laser surgery has taken its place in the medical world as a reliable method that is safe which provides consistent results.

The UV light produced by the excimer laser reshapes the corneal tissue in a certain way and corrects the refractive defects. The laser is outfitted with an eye tracker, so even if the patient moves their eye, laser beams are controlled by the system to counter such movement.

What are the Examination and Tests for Excimer Laser?

There are two important factors for the patient before and during the examination.

  1. Is the patient’s eye suitable for treatment?
  2. If appropriate, what type of treatment will be most successful?

Pachymetry measures the corneal thickness. Corneal thickness is vital for availability to excimer laser. Detailed examinations might be required which includes; pupillary diameter, visual acuity, eye pressure, and biomicroscopic examination.

After the examination, your refractive surgeon will plan your surgery and give you information about your eye.

  • iLasik
  • Lasek


LASEK is a treatment method that has been FDA approved since 1995, that is used in the correction of small to medium degree vision impairments. It is a surface ablation technique applied under the corneal epithelium. LASEK’s application is smooth since the operation lasts for 10-15 minutes and pain-free. However, it’s biggest disadvantage is that it has a lower degree of patient comfort compared to iLASIK due to the burning, stinging sensations and light sensitivity that develops about half an hour after the operation and can last four to five days, which can be quite distressful depending on the patient’s pain tolerance.

The advantages are that it can be used on eyes that are not suitable for iLASIK, or on patients that does not want people to know they had excimer laser surgery for whatever reason, since as opposed to iLASIK, LASEK technique does not leave a mark that can be noticed through an examination.

Cataract Treatment

What is Cataract?

Cataract is the most common form of eye problems. In a healthy individual’s eye, the lens is transparent, allowing the rays to directly reach the retina, creating a sharp and clear image. Cataract is the opacification or fogging of the lens, which contributes to blurry vision. This can lead to a reduction in vision as the lens becomes less and less transparent. The sharpness and color of objects cannot be identified clearly, as if looking out through a dirty window. The opacity of the natural lens in the eye gradually increases with time.

The only treatment of cataract is through surgery. Today, with the development of modern techniques, cataract surgery can be performed without needles, narcosis or hospitalization. The natural lens with the cataract is extracted and replaced with an adjusted synthetic intraocular lens (IOL).
