Lasik eye surgery
The laser surgery is a revolution in ophthalmology. It treats the visual defects until now compensated by eye glasses or lenses and thus makes it possible to flatten the cornea of a myopic eye or to bombard that of a hyperopic eye. The LASIK is the Laser in Situ Keratomileusis and it is known as corneal refractive surgery. Indeed, Keratomileusis is carried out to sculpture the cornea thickness which is called corneal stroma. Besides, LASIK is, along with PKR, the most frequently used refractive surgeries in the world. It provides excellent visual results and allows patients to no longer wear glasses or lenses. It is estimated that more than 30 million LASIK interventions have been performed over the last 20 years.
Lasik is a laser eye surgery intervention that can permanently correct these four vision defects: Myopia which consists of a blurred vision by far, hyperopia a near vision blur, astigmatism blurred near vision and by far and presbyopia which is an aging of the eye from 45 years causing difficulty to read. The preoperative examination such as corneal topography evaluating the cornea regularity, measurement of the cornea thickness, also called pachymetry, pupillometry, etc allows the surgeon to know if the patient is eligible for this surgery, if the eye has specific characteristics that may promote the occurrence of certain side effects. Moreover, the laser cannot fix everything. "Beyond a myopia of - 10 dioptres or hyperopia or astigmatism of + 5 dioptres, it is better to advise the implant.

Excimer Laser
The refractive surgery will consist in sculpting the cornea in order to modify the thickness of the tissue of its curvature radius according to the degree of the vision defect to be treated in the centre, peripherally, homogeneously or not, in order to increase or reduce the optical power. This cornea remodelling is done with a specific laser, called the Excimer laser. It is deemed the finest laser for corneal surgery, its impact has a precision of the order of 0.25 microns (0.00025 mm) and can be used in two different ways:
The Surface Laser or Photo Keratectomy Refractive (PKR) is used directly on the cornea surface, a few microns thick, after having removed the epithelium with a small brush. The correction is delivered on the superficial stroma, located just beneath the epithelium. This technique is possible for low to medium myopia. It is particularly recommended for people whose corneas are thin, irregular, or have some abnormalities such as scar. At the end of a PKR, a bandage lens is placed on the eye.
The intrastromal laser or LASIK is a "superficial corneal flap" made before carving the corneal stroma directly, deeper than the PKR. In practice, a small flap is cut on the surface of the cornea with a femtosecond laser. In fact, it is a laser that works with extremely short pulses, of the order of the femtosecond. The flap is lifted up, then the cornea sculpted with an excimer laser. The corneal flap is then put back in place. No sutures are necessary, it will heal on its own. Lasik is particularly suitable for hyperopia.
How is laser eye surgery performed?
The Lasik is a computer assisted intervention and is performed under local anesthesia. It is done by simple eye drops instillation that numb the surface of the eye. There is no intraocular gesture or implant placement. This method is carried out following three steps. First, the surgeon cuts the stromal flap of the cornea. Secondly he passes the laser on the cornea tissue for a photo-ablative correction. Then the surgeon rests the flap on the modified cornea tissue.
During the eye surgery, the patient is installed under the femto-second which is the laser for cutting the cornea flaps. The eyes are locally anesthetized through drops and spacers will be placed. The surgeon invites the patient to fix a red light in order to center the lasik. Then, the femto laser cuts the covers which takes 35 seconds per eye. During the procedure, the patient will not feel any or pain.
Postoperative effects and recovery after Lasik procedure
The eye laser surgery does not require hospitalization. The most common consequences of Lasik are such as tingling, sensation of having a dust in the eye, tearing, and sensitivity to light. In case the patient feels a postoperative pains, simple painkillers will be enough. Paracetamol and codeine, can also be taken after the procedure if necessary. These postoperative effects mostly last around 2 to 3 hours.
Regarding eye discomfort, it can be reduced by diluted anesthetic eye drops that can be applied for 3 hours after the procedure. The surgeon will prescribe to the patient an antibiotic for four days, an anti-inflammatory for three months and artificial tears to compensate for tear dryness for 3 months.
Result and outcome after laser eye surgery
The result is almost immediate after the Lasik intervention. The following day, the patient has already recovered 80% of his visual acuity. The improvement in vision then continues for 3 months. After that period and unless some surgical retouching was needed, the patient will recuperate their vision. Lasik removes the need to wear glasses or lenses Lasik intervention has several advantages,
Indeed, it is precise and effective, it is guided by the computer tool in support of the ophthalmologist surgeon. If the result is not satisfactory, editing is possible.
Lasik is a 100% safe surgery. The intervention has been used for more than 20 years, all over the world without problems.
Advice before and after Lasik eye surgery
A preoperative consultation is carried out by the ophthalmologist, it is intended to assess the patient’s vision defect, to seek possible contraindications to such surgery and to choose the most appropriate technique for them. The patient will be provided by all information related to the intervention. It is necessary to remove the contact lenses 2 days before if they use soft lenses, and 3 weeks before for rigid or semi-flexible lenses. After a thorough examination, your pupils will be dilated and it will be difficult to drive and read for few hours.
After the procedure, the patient can leave the clinic and can resume work the following day. Furthermore, it is essential to wear sunglasses, not only because it is more comfortable for the patient, but also because solar UV is toxic to the cornea. The first six nights after the operation, it is recommended to put night mask on the eyes to protect them.
It is forbidden to rub the eyes for up to two/ three weeks, the patient needs to allow the thin lamella cut in the cornea to heal. It is advised not to wear eye make-up, neither on the eyelids and eyelashes. Sprays, such as deodorants, should be handled with care so as not to get into the eye and cause irritation during the first three weeks. Pools should be avoided for three weeks because of the risk of infection if the water is not clean. Violent sports such as box are prohibited for three months.
