Six-month data for myopia treatments with the SCHWIND AMARIS laser show that it is effective and patient friendly.

Six-month data for myopia treatments with the SCHWIND AMARIS laser show that it is effective and patient friendly.

The multi-centric LASIK myopia study, conducted by Maria-Clara Arbelaez and colleagues, enrolled 358 eyes. Of all the eyes, 65% achieved a postoperative uncorrected visual acuity (UCVA) of 20/16 or better and 98% achieved a UCVA of 20/20 or better. Target refraction was also found to be good, with 96% of treated eyes falling into the ±0.5 D range.

Aberration-free treatments were also found to be very safe. More than 55% of eyes gained one or more lines of visual acuity after six months and the induction of higher order aberrations, compared with non-aspheric treatment, was minimal. The total RMS of postoperative higher order aberrations (for 6 mm analysis diameter) rose by an average of just 0.07 µm. This also resulted in higher contrast sensitivity for patients.

Importantly, good results were seen very shortly after treatment, with study participants attaining the same visual acuity as the preoperative best corrected vision just one day after the procedure.
