PRK or PHOTOREFRACTIVE KERATECTOMY
This is the first technique using the Excimer Laser for the treatment of visual defects. This technique
Treatments
Refractive surgery
Myopia, hyperopia, astigmatism and presbyopia
TRANS PRK
Schwind Amaris Excimer Laser technique: Abrasion of surface epithelial cells by the laser followed by an abrasion
LASEK
LASEK is a technique where an epithelial flap is performed with a diluted alcoholic solution prior to the use of the Excimer Laser.
LASIK
This is the most common technique used by refractive surgeons in the USA and Europe. Available in
FEMTOLASIK - FEMTOSECOND LASER LDV Z6 (ZIEMER)
The Femtosecond laser is a surgical tool for corneal cuts.
WAVE FRONT CUSTOMIZED VISUAL CORRECTION BY ABBEROMETRY OR WAVE FRONT GUIDED CUSTOM LASER, ZYOPTIX
Like our fingerprints, our eyes have an individual shape with their own characteristics. Custom aberrometry treatment uses
ULTRA-THIN LASIK
This is the Lasik technique with a very thin cap (90 to 110µ, average 100µ) allowing an ablation
RADIAL KERATOTOMY(no longer practiced)
This was the first surgical technique used for the correction of myopia. This technique was commonly used in the
PHAKIC INTRA-OCULAR LENS
Definition: the placement of an intraocular implant, correcting the refractive error, without removal
ARTISAN
Local or general anaesthesia preferred. Opening of a small corneal incision. Placement of a lens that is attached at the level of the cornea.
ARTIFLEX
This is a myopic phakic implant (without removing the natural lens) with the specific characteristic of being foldable. Its
VISIAN ICL
Visian ICL is a collameric phakic implant (without removal of the natural lens) and is the result of the latest technology
BIOPTICS
This is a surgical technique combining the insertion of an intraocular implant of the Artisan, Artiflex or Visian ICL type followed by laser treatment

Complications specific to each surgical technique: Radial keratotomy Daily visual fluctuations Glare and night halos Secondary or progressive hyperopia
LASER Excimer
The Excimer Laser, whose name comes from EXCIted diMER, uses the energy of the photons released by the electrical excitation of the Dimer
S.M.I.L.E (SMall Incision Lenticule Extraction)
This is a new surgical technique for myopia and astigmatism using Femto Second laser. It is performed under anaesthesia

PRESBYOPIA : Laser and Multifocal Implants
Presbyopia is an accommodation disorder induced by a decrease in the elasticity of the lens and which appears physiologically after
MULTIFOCAL AND PSEUDO-ACCOMODATIVE IMPLANTS
Implants used in lens and cataract surgery to allow distance and near vision without glasses.
Laser Yag Capsulotomy
Secondary cataracts can occur after cataract surgery with an intraocular implant. This is
Therapeutic Excimer
This is the same Excimer Laser used in refractive surgery. The surgery is performed on an outpatient basis, under local anaesthetic
Therapeutic Treatment
KERATOCONUS
This is a progressive corneal disease that can begin to show signs around the age of 20 and leads to a conical bulge in the cornea
