<br/><br/> Corneal refractive surgery performed by excimer laser has matured considerably and was able to cover from +6 to 12 diopters of sphere and up to 6 diopters of astigmatism with good, predictable and safe outcomes ⁽³⁾⁽⁴⁾. Hyperopia had been one of the frontiers approached with caution by modern corneal refractive surgeons, but evidence had confirmed its feasibility for up to 7 diopters with acceptable induction of high order aberrations (HOA), equivalent to those induced by previous generations of excimer laser corneal surgical devices in hyperopic corrections up to +3 spherical diopters ⁽⁵⁾
