Why undergo laser eye treatment?

Nearsightedness (myopia) and astigmatism, recognized as common refractive errors, affect many individuals. For a considerable number of people, the convenience of daily life and engagement in various activities is significantly heightened by opting for laser eye treatment, eliminating the need for glasses and contact lenses.

Laser vision correction not only addresses visual challenges but also marks a transformative shift towards a more liberated and convenient lifestyle.


How does CLEAR work exactly?

The procedure is performed with a singular laser, the Ziemer Z8 Femtosecond laser.

  1. The laser is used to prepare a disc-shaped tissue (Lenticule) within the cornea.
  2. The surgeon then removes the prepared disc (Lenticule) through a small incision in the surface of the cornea.
  3. The removal of the Lenticule causes the shape of the eye to change, which corrects your vision.

A simple CLEAR explanation:

CLEAR – minimally invasive laser vision correction

Preliminary examination

In the preliminary examination, a comprehensive initial evaluation of the patient's eyes is undertaken. Precise measurements are taken to construct a detailed map of the cornea with high precision. Through this detailed analysis, unique features and potential risks associated with the patient's eyes are identified, offering essential information before the surgery is undertaken.

Follow-up examination

The first follow-up examination is typically scheduled for the day after surgery. During the follow-up examination, the eye is thoroughly examined again with a slit lamp to ensure that the treatment has brought the desired success. The utilization of a slit lamp enables a detailed examination of the eye, providing valuable insights into the effectiveness of the treatment and contributing to the ongoing monitoring of the patient's postoperative recovery.

What are the CLEAR Benefits?

CLEAR is a minimally invasive and gentle procedure that uses low laser energy to correct vision. This allows potentially for more corneal stability after surgery.

Unlike other laser eye surgeries, CLEAR is a single laser procedure. It’s fast and provides more comfort and convenience to you during your surgery.

CLEAR is a flapless, gentle procedure. The upper layers of the cornea are minimally disturbed. Nerves are less affected, which can reduce the incidence of dry eyes.

Corneal Lenticule extraction (CLEAR) is considered as the next generation of lenticule applications. The correction is done by a single laser: the Ziemer FEMTO Z8. Made in Switzerland.

Questions? Answers.

CLEAR is designed to correct nearsightedness with or without astigmatism. Each person has a unique eye anatomy and only a careful evaluation by your eye care specialist can determine if you are a good candidate for CLEAR.

The procedure takes about 15 minutes, and the laser correction itself is only 35 to 40 seconds.

Every healing process is individual. In most cases, visual acuity is very good one or two days after the operation and stabilizes within one week. Normally, you will be able to drive, work and participate in sports within a few days.

CLEAR is attested by the EU declaration of conformity (CE mark) and therefore meets EU safety, health, and environmental protection requirements. CLEAR has the same low risks as other refractive surgeries. Your eye care specialist will discuss these with you.
