FEMTOSECOND LASER TECHNOLOGY (VISUMAX)
Carl Zeiss has over 160 years of experience in the development of optics and Zeiss high performance optics are key to providing an optimum corneal flap. In general, patients who qualify for LASIK are also candidates for the VisuMax laser corneal flap treatment, and thus will benefit from its accuracy and gentleness.
Flap creation with the VisuMax is a completely bladeless procedure. The creation of the corneal flap with the VisuMax is very fast and takes approximately 20 to 30 seconds, while the complete LASIK procedure may take approximately 15 minutes. A very accurately focused laser beam is guided through to the cornea in a computerized treatment that is unique to each patient. The laser beam moves across and through the cornea, creating a layer of very tiny bubbles under its path. These bubbles quickly disappear, and the tissue above the bubbles becomes the corneal flap that can be easily lifted by your surgeon. Everyone has a curved cornea. Nature often provides us with the best answers, and the VisuMax features a unique, curved contact glass to maximize patient comfort. This technology allows for the patient to maintain visual sight during the entire procedure. This is possible since the curved contact interface attaches to the cornea during the treatment and the cornea is only slightly flattened, which prevents unnecessarily high intraocular pressure and stress to the eye. This provides maximum comfort and it allows you to see throughout the entire procedure, unlike with microkeratomes or other femtosecond lasers, where your vision is “blacked out” for awhile and patients have reported feeling uncomfortable pressure. Patients often describe the VisuMax procedure like the insertion of a soft contact lens. Due to the Zeiss high performance optics, the laser beam is guided very precisely to the desired depth, resulting in most accurate flap thickness. In addition, the laser beam is directed in a very focused manner, which allows the doctor to apply only minimum laser energy to the eye during the treatment. As a result, the tissue outside the defined area of the cut remains untouched. Since the VisuMax is able to create very thin corneal flaps, some patients who were previously not a candidate for LASIK due to thin corneas, are now benefiting from the procedure, thanks to the VisuMax. Your doctor will make the final determination.
Benefits of Blade-Free
The VisuMax laser provides more stability and greater flap precision when compared to LASIK. LASIK’s greatest complication is flap problems after surgery. Because blade free is so precise, this risk is significantly reduced.
The blade-free Lasik vision correction surgery can produce real benefits for some patients.
- Decreased risk of flap complications.
- Decreased incidence of postoperative dry eye
- Unlike other alternatives to LASIK, it preserves many of the benefits of LASIK including a short and largely pain-free recovery.
- More accurate outcomes in terms of patients’ postoperative vision.
- Benefits of vision correction surgery are available to those who might have previously been poor candidates.
- Less pressure on the eye during the surgery.
- Reduced incidence of patients needing a second operation to correct their vision.
- Flaps created with a laser are less likely to become dislodged later
