Excimer laser vision correction
LASIK, commonly referred to as laser eye surgery, is a type of refractive surgery for the correction of myopia, hyperopia, and an actual cure for astigmatism, since it is in the cornea. LASIK surgery is performed by an ophthalmologist who uses a laser or microkeratome to reshape the eye's cornea in order to improve visual acuity For most people, LASIK provides a long-lasting alternative to eyeglasses or contact lenses.
Ufa Eye Research Institute has the most advanced excimer laser systems for vision correction.
Tecnolas 217Z100P (Germany) is a computer-assisted system that combines diagnosing, planning and laser vision correction.
ZYOPTIX® Advanced Control Eyetracking (ACE) ensures accuracy and delivers the laser pulses exactly to the spot on the cornea even in those cases where the patient moved the eye inadvertently during treatment. The optimum Laser speed shortens the treatment time.
ZYOPTIX® Personalized Treatment Advanced (PTA) algorithm is intended to treat higher-order aberrations without inducing spherical aberration. PTA allows to treat myopia, hypermetropia and astigmatism, using extensive nomograms which reduce the need for a second procedure to less than 1%.
ZYOPTIX® Tissue Saving (TS) allows ophthalmologists to produce much thinner cuts in the cornea than previously. This enables people who would have been unsuitable due to having a thin cornea to now have laser vision correction. This is approximately 25% of people.
ZYOPTIX® Aspheric allows patients who have higher prescriptions to have laser vision correction. It involves using the Zyoptix system to correct all the irregularities on the surface of the cornea. It is not suitable for everyone, as it removes about 15% more tissue then the tissue saving option. This can decrease the night time symptoms associated with the standard LASIK system by helping to maintain the natural curvature of the cornea. It has also been shown to increase contrast sensitivity.
