Laser vision correction is recommended up to minus 12 or plus 6 diopters. Those who have a more severe refractive error, laser is unfortunately not an optimal solution. Today, however, there is an alternative to glasses or contact lenses in these cases too. We use a successful surgical technique identical to the one used for cataracts and performed worldwide, which can sometimes improve vision to perfect clarity. The minimally invasive ultrasound surgery is performed, which is safe and has an extremely fast recovery rate. Capable of curing even extreme refractive errors, this intervention – which is identical to the one used for cataracts – is recommended for severe farsightedness of +6 to +12 diopters, and severe shortsightedness of -12 to -30 diopters.
