Wavefront customized, or individualized vision correction
What is customization?
Customization means precisely measuring whole optical defect of every person’s eye and programming laser vision correction bases on individual characteristics of each person. Besides ordinary optical defects of the eye such as nearsightedness, farsightedness and astigmatism, the optical system of the eye may have other abnormalities called “aberrations” which can not be measured and treated with standard diagnostic and laser devices. During the process of customization, these abnormalities, which are specific for every individual eye, are measured and treated by sophisticated diagnostic devices and laser machine. This process is also called wavfront customization or wavefront guided customized ablation, because the device that measure aberrations of the eye works base on wavfront sensing and measuring. The wavefront sensor which is called “Aberrometer” has been using in astronomy to measure and eliminate aberration to more clearly visualize space elements
Potential Benefits of Wavefront-Guided Custom vision correction
Wavefront technology is groundbreaking because it has the potential to improve not only how much you can see, visual acuity measured by the standard 20/20 eye chart, but also how well you can see, in terms of contrast sensitivity and fine detail. This translates into a reduced risk of post-LASIK complications, such as glare, halos, and difficulty with night vision.
How much you see depends on vision defects known as lower-order aberrations associated with common refractive errors including myopia, hyperopia, and astigmatism, which traditional LASIK or PRK can treat.
How well you see can depend on presence of the type and numbers of visual distortions known as “higher-order aberrations”, which can include irregularities other than common refractive errors. These higher-order aberrations can create problems such as decreased contrast sensitivity or night vision, glare, shadows, and halos. Unlike traditional LASIK and PRK, custom vision correction treats both lower- and higher-order aberrations.
In summary, the advantages of custom laser vision correction are as flow
Greater chance of achieving 20/20 vision
Greater chance of achieving better than 20/20 vision
Reduced chance of losing best corrected vision
Reduced chance of losing visual quality or contrast sensitivity
Better chance to improve quality of vision
Reduced chance of night-vision disturbances and glare
Zyoptix means that laser eye treatment is now unique and CUSTOMISED to each eye. With Zyoptix, treatment is designed specifically to treat your individual vision errors.
Zyoptix could improve the quality of your vision. In a clinical study conducted by Independent Refractive surgeons on behalf of Bausch & Lomb, significantly more Zyoptix patients had fewer problems with night driving than patients undergoing regular standard treatment.
Each Zyoptix assessment involves an extra diagnostic (screening) process to let the surgeon understand your vision better and select the most suitable treatment for you.
In the Zyoptix system the latest, most advanced technology is used to detect and treat very small vision errors.
The Zyoptix system has many advanced built-in safety features that help to optimize the success of your treatment.
The zyoptix system has a very advanced feature called iris recognition. As it was mentioned earlier, during diagnostic procedure the Zywave captures an image of each patient's iris, produces a unique digital iris key, automatically identifies patient's eye like a finger print so improved safety for each patient and is able to track the eye more accurately during the treatment. Compensates and corrects for intra-operative eye movement in every dimension, including cyclotorsion and pupil shift.
Better quality of vision
High patient satisfaction
At Perian Eye Clinic we are pioneer in taking advantage of this very efficient technology
