Laser eye surgery: indications, procedure and price

About three out of four people are affected by vision disorders in France. Many of them often have recourse to eye surgery, with a view to no longer wearing lentils Where glasses. To this end, one of the alternatives, whether the person has myopiaof the’astigmatismfrom presbyopic and others, stay laser surgerywhich makes corrections to visual disturbances.

Called again refractive surgeryit is indicated in specific cases and can cause various complications. How is the eye laser surgery and what is its price?

Laser Eye Surgery: Benefits and Indications

The eye laser surgery refers to all of the ophthalmic operations which make it possible to correct certain refractive defects of theeye. It consists of cutting out a hood at the level of cornea, using a laser. The flap is rested and scarred after a few hours, without any sutures, when the operation is done using advanced techniques. To get rid of your optical prostheses, lentils or glasses, head to theNice Institute of Ophthalmologywho will provide you with appropriate support.

In fact, the vision defects corrected by eye laser surgery are :

The myopia translates to a elongation of the eyeballwhich is manifested by a swelling of crystalline and some cornea. For this purpose, the image is observed in front of the retina instead of being observed on it. Laser eye surgery allows in this context, to make a readjustment of the curvature of the cornea through the laser.

L’astigmatism impairs not only near vision, but also distance vision. It is usually caused by a malfunction of the crystalline or cornea, and may be related to a farsightedness or a myopia. The refractory surgery allows to perform a deep ablation, to regulate the surface of the cornea.

L’farsightedness is generally caused by an anteroposterior axis of the eye being too short. This results in the focusing of the image behind the retina, the complete opposite of myopia. This makes very close objects blurry.

Appearing during the aging process, the presbyopic is caused by a loss of elasticity and flexibility of the lens. The eye laser surgery of a patient with presbyopia is practiced using different methods: monovisionthe multifocalitythe trifocality and the restoration of an accommodative function partialby inserting an accommodative implant.

In addition, laser eye surgery can treat several other eye damage as :

  • diabetic retinopathy;
  • Hypertensive retinopathy;
  • the glaucoma ;
  • The cataract ;
  • Vascular pathology associated with thrombosis;
  • macular degeneration;
  • Peripheral retinal lesions or the prevention of retinal detachment.

Laser eye surgery: procedure

Several techniques can be used to practice refractive surgerybut some processes remain the same. The very first step is to determine whether or not it is possible to do surgery. To achieve this, the surgeon performs specific examinations eye surgeryand then chooses the appropriate technique.

However, he recommends that the patient avoid wearing contact lenses for 48 hours before the day of the operation. This, in order not to cause a irritation from ocular surface.

The operation begins with the application of a few drops of anesthetic solution on the eye. The surgeon then places a spreader, to keep the eye open throughout the procedure. At the same time, he poses a small suction cup on the cornea, in order to flatten it.

Regardless of the technique chosen, the function of the laser is to readjust the cornea so that the patient can regain good sight. The techniques of eye laser surgery are there PRK technique (photocratomy), the LASIK techniques (Laser in-Situ Keratomileusis) and the SMILE technique.

Laser eye surgery: operation and post-operative follow-up according to each technique

As noted, laser eye surgery is technique-dependent, as is recovery.

Surgery using the PKR technique

Appearing to be the oldest technique, the PRK technique is often used in the context of small optical defects as well as for very thin corneas. Once the most superficial layer in the center of the cornea is removed, the surgeon applies the excimer laser on the surface of the cornea, in order to make corrections to the myopia. At the end of the intervention, a protective lens is placed in the patient and the patient must keep it for three to five days.

It is possible that the patient feels some discomfort among which, watery eyes or the blurred vision wake. But, the vision gradually improves in the following days and the discomfort also decreases.

With the PKR technique, the eye laser surgery requires a convalescence of four to five days. The patient can resume with his professional occupations after this period. As for driving over long distances, it is only possible after a period of seven to ten days.

Surgery using the LASIK technique

The LASIK techniques consists in first cutting a corneal flap speak femtosecond laser. Then the surgeon use it excimer laser to reshape the surface of the cornea, with the aim of treating vision disorder.

The discomfort in this context gradually decreases in the hours following surgery. The patient’s vision progresses gradually. It is possible that a dry eye occurs, but this is mitigated by administration of artificial tears. In the first night, the protective shells should be kept in the eyes so that the patient does not touch his eyes unconsciously during sleep. But, they can be removed upon waking.

The resumption of professional activity is possible the day after laser eye surgery using the LASIK technique. In the case of screen work, it is recommended to reduce the patient’s working time, so that the latter is not confronted with eye fatigue.

In addition, it is possible to start driving over short distances the day after the operation. But, over long distances, it will take three to four days, as well as in the context of activities that do not present a risk to the eyes (such as cycling or jogging).

Surgery using the SMILE technique

Being a recent technique, the SMILE consists in cutting in three dimensions an ultra-thin thickness of the cornea, by means of the femtosecond laser. This gives the eye the desired curvature. The doctor removes this ultrathin lamella through the micro-incision.

A healing made by micro-incision is faster than a standard incision (in case of Lasik for example). However, the pains where the feelings of sand in the eyes may occur as a result of laser surgery.

An examination is necessary the next day, and seven to ten days following the operation. The patient must observe approximately one day of rest after the intervention, before resuming work.

In addition, the patient must follow a treatment after laser eye surgerythis according to the type of intervention technique and the type of vision disorder corrected. This treatment usually includes anti-inflammatories or some antibiotic eye drops, for a week. It also includes lubricating eye drops to continue for several weeks. For the smooth running of the postoperative course, control visits are necessary.

Possible complications of refractory surgery

The eye laser surgery presents several risks. Among the adverse effects that may occur throughout recovery, we have:

  • dry eye;
  • Impairment of night vision;
  • The split vision ;
  • The perception of a luminous halo;
  • Inflammation of the cornea oreye infection.

It is with a view to reducing these risks that it is crucial to carry out in-depth preoperative examinations. These not only make it possible to determine operative eligibility, but also to check whether there is a contraindication. Better yet, the eye laser surgery must be carried out by well-trained doctors who have proven experience, so that the patient can benefit from secure care.

Price and reimbursement of laser eye surgery

The price of the eye laser surgery depends on the operating technique:

  • The PKR technique: the cost for both eyes varies between €2,000 and €2,500;
  • The LASIK technique: it varies between 2,500 and 3,500 €;
  • The SMILE technique: it varies between 3,000 and 3,500 €.

Note that the refractory surgery is not reimbursed by social security, since it is a comfort operation. However, some mutual health insurance offer reimbursements of up to €1,200 per year and per beneficiary.
