WebJul 9, 2024 · Myopia means nearsightedness — blurry distance vision and clear near vision. If the cornea has the proper arc, then flaws elsewhere in the eye typically produce shortsightedness. Myopic astigmatism, by contrast, happens when the principal meridians in the cornea generate nearsightedness and astigmatism. Hyperopic astigmatism. WebCompared to myopic LASIK, hyperopic LASIK yields a smaller effective optical zone and increases higher-order aberrations, 1 and treatment centration is less forgiving, which can cause more problems with night vision and produce less predictable outcomes. 2 This was especially true with early excimer laser platforms that used broad-beam or ... incompatibility\u0027s fu
