Personalised ‘eyevatar’ ray tracing technology unlocking HD vision

ray-trace guided laser eye procedureMore than seven million Aussie adults living with the common eye conditions, myopia and astigmatism, are set to benefit from the launch of next-generation, ‘customised’ laser eye technology designed to achieve high-definition (HD) vision, this Saturday, December 2, 2023.

Unveiling of the personalised, laser eye correction treatment employing NASA Hubble Space telescope eye tracking technology this Saturday, has been spearheaded by new Australian-first research revealing 90 per cent of treated patients achieved 20/15 vision (better than 20/20 vision), while 50 per cent of patients achieved 20/12.5 vision.

According to new research author, Ophthalmologist, and Director of PersonalEYES, Associate Professor Chandra Bala, Sydney, who has performed the advanced, ray-tracing laser eye treatment on more than 1,000 patients to date, this novel, diagnostic technology is poised to improve the diagnosis, treatment and outcomes for people living with myopia and astigmatism.

The technology generates a personalised, multidimensional, 3D model of the eye, or ‘eyevatar’, enabling eye surgeons to move beyond 20/20 vision, and in most cases, to achieve HD-vision,” said A/Prof Bala.

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,” said A/Prof Bala.

This technology provides the most accurate method currently available for measuring and modelling the eye. Ten years ago, these calculations would have taken 24 hours. Now they take just four minutes. Given each set of eyes is unique, treatment should not be a ‘one-size-fits-all’ approach,” A/Prof Bala said.

Clinician Scientist Ophthalmologist, Westmead Hospital, and Glaucoma Specialist, PersonalEYES, Clinical A/Prof Andrew White, Canberra, maintains there is a broad community misconception that 20/20 vision is ‘perfect vision’. It is rather, ‘average’ eyesight that 90 per cent of patients who undergo standard LASIK Surgery for myopia can achieve.

In order to go beyond 20/20 vision, treatment must be customised to the eye. This Australian-first, next-generation, ray-tracing laser eye technology is making this possible. The technology offers Australian adults living with common eye conditions, the opportunity to throw away their glasses and contact lenses for good, and to potentially, save money in the long-term,” A/Prof White said.
