Innovation for your eye care in Sherbrooke

Correction of Myopia, Hyperopia or Astigmatism Using Zyoptix

At 100% Vision in Sherbrooke, Lasik vision correction, with or without Intralase, can be combined with another technology: Zyoptix. For eye care in Sherbrooke, trust a team of professionals. 


Zyoptix has all the same characteristics than tailor-made Lasik but is also operating in the state of the art technology A.C.E. It is a technology that also offers iris recognition. It also allows you to get an eye surgery that is personalized in every way for your eyes. For people with astigmatism higher than 1.5 dioptres, Zyoptix is highly recommended. It can correct astigmatism up to 6.5 dioptres.

Zyoptix at a Glance

  • Treats optical aberrations of the eye
  • Reduces glare and halos around bright lights
  • Improves visual acuity and sharpens vision
  • Increases sensitivity to contrast
  • Provides customized treatment adapted to each eye

Zyoptix Is Better Because It Offers More

Zyoptix is a major innovation in refractive surgery, earning the silver medal in the biotechnology and medical technology category at the highly prestigious European Technology Innovation Awards. Zyoptix refractive surgery is a very effective technique producing better results for day time vision (5% increase compared to the best corrected vision, with glasses, prior to surgery) and evening and night time vision (50% increase compared to the best corrected vision, with glasses, prior to surgery).

Possible Side Effects

It is important to understand that individual responses to vision correction can differ, depending on the specific characteristics of each person. In addition, the side effects associated with Lasik are reduced to the point of virtual non-existence, although they are possible.

Lasik Compared to Zyoptix

Visual Acuity
Both types of refractive surgery offer the promise of a significant improvement in visual acuity. In fact, researchers evaluated the optimum vision of 114 patients before and after vision correction. Pre-surgery visual acuity was measured with the best possible refraction, or in other words, while wearing their glasses or contact lenses. 

Three months after Lasik surgery, patients demonstrated a 28% improvement in their vision acuity (post-surgery vision compared to vision corrected with the use of glasses or contact lenses prior to surgery). 


In comparison, Zyoptix vision correction ranked higher in merits and quality, with improved vision recorded in 51% of patients (post-surgery vision compared to vision corrected with the use of glasses or contact lenses prior to surgery). These results justify the silver medal that was awarded at the European Technology Innovation Awards.


Corneal Tissue
Analyses of the preservation of corneal tissue were conducted, demonstrating that Zyoptix removes significantly less tissue than standard Lasik surgery, especially in cases of acute myopia. 


Quality of Vision
The 114 patients underwent a vision test only one month after refractive surgery. The following results were obtained:

The Surgical Procedure

Lasik refractive surgery is performed in a series of stages:


1. The eye is anesthetized using eye drops.

2. A flap (thin layer of the corneal epithelium) is produced using a new generation of microkeratomes that leave the joint in a superior position rather than a nasal position.

3. The flap is raised in order to carry out the laser treatment directly on the stroma (the second layer of the cornea). This consists of sculpting the cornea in order to change the curvature of the eye using the laser ray.

4. The flap is returned to its original position (therefore, the epithelium is left intact after the operation). As a result, healing and visual recuperation is much faster and less painful.

In addition, there is a reduced need for post-operative care, which means that a reduced amount of eye drops are required after this type of refractive surgery.

Possible Side Effects

This new technique, which is designed to improve the results of vision correction, is extremely effective. However, it is important to understand that individual reactions to Zyoptix can differ, depending on the specific characteristics of each person. It is important to understand that depending on the specific characteristics of each individual, response to surgery can differ. Thanks to this new technique, the side effects associated with Lasik are reduced to the point of virtual non-existence, although they are possible.


Dry Cornea
The eye is often dryer after refractive surgery. In light of this, we recommend the use of artificial tears several times per day for the first few months following surgery.


Under-correction or over-correction

The eye may be slightly over- or under-corrected following the operation. If this effect causes impaired vision, a second procedure may be required, and can be performed approximately 2 or 3 months after the first intervention.


Other possible side effects

Thanks to cutting-edge surgical techniques, the risk of infection is extremely small, but it remains a possibility. There may also be some inflammation at the interface, which should be treated using cortisone eye drops.
