The article reports on the findings of a study regarding the effectiveness of presbyLASIK with induced hyperprolate spherical aberration in the treatment of presbyopia. Hugo F. Sutton noted that the increase in Zernike 4,0 value offers satisfactory near vision without affecting distance vision or causing asthenopia. It is hypothesized that the use of presbyLASIK to induce corneal hyperprolaticity would offer good near vision without lessening binocular distance uncorrected visual acuity.
