Subjects were positioned in a headrest to minimise head movements and read continuous text on a computer monitor for 10\u00a0min at an angle of 25\u00a0degrees downward gaze and an accommodation demand of 2.5 D.

Following the near work task, fellow eyes also displayed a symmetrical change in superior corneal topography (hyperopic defocus) which correlated with the position of the upper eyelid during downward gaze. Greater changes in the spherical corneal power vector (M) following reading were associated with a narrower palpebral aperture during downward gaze (\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a00.07 for more myopic and\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a00.03 for less myopic eyes). A significantly greater change in J0 (an increase in against the rule astigmatism) was observed in the more myopic eyes (\u22120.04\u00a0\u00b1\u00a00.04 D) compared to the less myopic eyes (\u22120.02\u00a0\u00b1\u00a00.06 D) over a 6\u00a0mm corneal diameter (\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a00.01).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Changes in corneal topography following near work are highly symmetrical between the fellow eyes of myopic anisometropes due to the interocular symmetry of the palpebral aperture.
