LASIK EYE SURGERY

The use of lasers in eye surgery is based on two basic properties of the laser. On the one hand, the use, especially with computer-aided control, allows a high level of precision, on the other hand, it offers mechanical contactlessness, which is of great importance in the field of microsurgery.

These properties are being used in laser eye surgery to treat the cornea by means of.

Laser ablation with the aim of permanently correcting a visual impairment. Lasik (laser in situ keratomeleusis) is the most commonly performed eye laser method. During the operation, a wafer-thin corneal cover, also known as a flap, is being removed and folded upwards. The subsequent vision correction is achieved with the excimer laser, which changes the curvature of the corneal surface and thus optimizes the refractive power of the eye.

Depending on whether the patient is short-sighted or far-sighted, the removal takes place in different areas. The flap is then placed back on the middle of the cornea. This sucks in again within a short time. Healing takes only a few hours and is usually painless. The patient should be able to see clearly the very next day.

The Femtolasik 

Femto Lasik is a further development of the Lasik method. The difference is in the creation of the flap.

With Lasik, the corneal flap is created with a very sharp computer-controlled precision blade. With Femto Lasik, on the other hand, a fine infrared laser is used for this process. For this reason, this procedure is suitable for a relatively thin cornea and for patients with pronounced visual impairment. This method is also gentler than the cutting with a knife. Nevertheless, it should be taken into account that both methods differ only with regard to how the flap is generated. The actual correction of the visual impairment is carried out by the performance of the excimer laser. Some ophthalmologists rely on the use of a current femto laser and at the same time use an outdated excimer laser. This combination does not achieve the desired result.

Wavefront Lasik

Wavefront technology is a further development of excimer laser technology.

With this procedure, an individual ablation profile can be created for each eye calculate. As a result, the optical aberrations of a higher order can be included in the eye laser correction. Thus, with the Wavefront Lasik, individual peculiarities of the eye are addressed. With this method, this also results in an improvement in visual performance, even in unfavorable lighting conditions.

For Whom is an Lasik Eye Surgery Suitable and How is it Performed?

A Lasik operation makes it possible to correct existing short-sightedness (-10 dioptres), long-sightedness (+3 dioptres), or astigmatism (5 dioptres) up to a certain dioptre value.
