This experiment was repeated for the same range of induced astigmatism with 1.5\u2010, 3\u2010, and 6\u2010mm artificial pupil diameters placed before one eye of 10 subjects dilated with 10% phenylephrine HCl.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results.<\/jats:title>\n                    <jats:p>Distance acuity deteriorated with astigmatism for all axes tested (p &lt; 0.01).

Distance and near acuity improved with a reduction in pupil diameter (p &lt; 0.01).

Uncorrected myopic astigmatism more than 1 D results in a large loss of distance acuity at no additional benefit to near acuity. Both distance and near acuities with and without astigmatism are benefited with a reduction in pupil diameter. Uncorrected hyperopic astigmatism results in deterioration of both distance and near acuities of pseudophakic eyes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1097\/opx.0b013e318288afb5","type":"journal-article","created":{"date-parts":[[2013,3,1]],"date-time":"2013-03-01T13:37:23Z","timestamp":1362145043000},"page":"378-384","source":"Crossref","is-referenced-by-count":38,"title":["Relation between Uncorrected Astigmatism and Visual Acuity in Pseudophakia"],"prefix":"10.1002","volume":"90","author":[{"given":"Archana","family":"Singh","sequence":"first","affiliation":[{"name":"Cornea and Anterior Segment Services L.
