There is no such thing as 0 risk in medicine.

However, with today's lasers and preoperative measuring devices, postoperative results can be predicted in over 99.5% of cases.<br The possibility of complications is present, but exceptional.

The risk of going blind is virtually zero.

Minor complications are estimated at less than 0.8% according to the SNOF (Syndicat National des ophtalmologues de France).

Laser surgery is some thirty years old, and has been around since the 1990s. Lasers have improved considerably, with micron-level precision, since the 2000s.

It should also be noted that, thanks to major technological advances in corneal topography, we are able to carry out ultra-precise pre-operative examinations, enabling us to pre-select eligible patients and obtain results that are close to 100% satisfactory.

Any operation inevitably involves risks of undesirable effects and potential complications.

• A sensation of dryness is common after laser treatment for the first few months. This is often well tolerated with the instillation of artificial tears.
• The risk of infection is exceptional, around 1 in 3,000 cases. Antibiotic eye drops are prescribed to prevent this.
• Light halos have been described by some patients, often already photophobic before the operation, with clear irises and large physiological pupils. In the vast majority of cases, this undesirable effect corrects itself spontaneously after 1 month.
• One absolute contraindication to laser treatment is a pathological cone-shaped cornea (keratoconus) due to its anatomical constitution and fragility.

For around 15 years now, preoperative measurement devices have been used to effectively detect these cases of exclusion.

Since their launch in 1987, these lasers have used Excimer gas.

Lasers are more powerful and faster, but the principle of sculpting the cornea remains the same.

Worldwide, around 1 million people a year undergo laser eye surgery to eliminate their dependence on glasses.

The risk of total loss of sight is so rare, if not non-existent, that there is currently no statistical data in the literature.

Most of the latest generation lasers, like the one at the Clinique du Parc, are equipped with an eye tracker.

A camera constantly follows the movements of the treated eye, even micro-movements. The laser adapts in real time to the position of the eye.

If the movement is too large, the laser will automatically stop until the fixation is resumed.

It is virtually impossible to unintentionally treat an area outside the treatment field.

Complications are possible, but exceptional.

The risk of going blind is virtually zero.

Minor complications are estimated at less than 0.8% according to the SNOF (Syndicat National des ophtalmologues de France).

The laser procedure is carried out under topical anaesthetic (by instilling drops only) to numb the surface of the eye.

There is no stinging around or in the eye.

Laser treatment is TOTALLY painless.

The femtosecond laser is used to make a fine cut in the cap, and the flattening cone is brought into contact with the eye for a few seconds to ensure that it follows the shape of the cornea.

Patients may feel a sensation of suction, and for some of them this causes a slightly unpleasant transient sensation.

NO, never.

Refractive surgery is performed exclusively under local anaesthetic using eye drops. No needles are required to numb the eye, just the drops.

The procedure is completely painless.

Depending on the technique used, postoperative patients may experience eye pain, which is usually well managed by painkillers, and photophobia for the first 48-72 hours.
