Ninety per cent of adult patients achieve ‘20/15’ vision or more with eyevatar
Next-generation, ‘customised’ laser eye technology could deliver high-definition (HD) vision for more than seven million Australian adults living with myopia and astigmatism.1
The personalised, laser eye correction treatment, launched in Australia on the first weekend of December, employs NASA telescope eye tracking technology.
It has been spearheaded by Australian-first research revealing 90% of treated patients achieved 20/15 vision (better than 20/20 vision), while 50% of patients achieved 20/12.5 vision.2

Associate Professor Chandra Bala, research author, ophthalmologist, and Director of PersonalEYES in Sydney, who has performed more than 1,000 ray-tracing laser eye procedures to date, said the novel technology is poised to improve the diagnosis, treatment and outcomes for people living with myopia and astigmatism.
“For the first time, we are now offering ‘personalised’ laser eye correction, employing NASA Hubble Space telescope (which measures the size of the nearest, transiting, earth-sized planet) eye tracking technology, that allows the laser to move faster than the eye, simultaneously detecting and accommodating for any eye movements like never before.
“This advanced diagnostic technology directs 500 beams of light at the eye, measuring and collecting data from the reflected light with microscopic precision of 1/100,000 of a millimetre, to generate a personalised treatment plan,”2 said Assoc/Prof Bala. “This technology provides the most accurate method currently available for measuring and modelling the eye.”
Assoc/Prof Bala said calculations that would have taken 24 hours ten years ago now take just four minutes.
“Given each set of eyes is unique, treatment should not be a ‘one-size-fits-all’ approach,” he said.
Assoc/Prof Bala’s independent research performed on 200 adult patients (400 eyes) living with myopia and astigmatism, from his everyday clinical practice, revealed 90% of those who underwent ray-tracing laser eye technology treatment achieved 20/15 vision (better than 20/20 vision); 50% of patients achieved 20/12.5 vision; while 8% of patients achieved 20/10 vision. Moreover, 98% of patients reported feeling ‘completely satisfied’ with the treatment, with between 38-40% of those who underwent ray-tracing guided laser eye technology treatment seeing one line or more on an eye chart better than what they ever did with glasses.2
