Our aim was to compare peripheral refractions in the same cohort of human eyes corrected with spectacle lenses vs soft contact lenses.\n                    <\/jats:p>\n                    <jats:p>\n                      <jats:bold>Methods:\u2002<\/jats:bold>\n                      Ten young adults with moderate to high myopia (\u22125.00\u2003D to \u22128.00\u2003D) were investigated. Open\u2010field autorefraction was used to measure on\u2010 and off\u2010axis refractions with the eyes in primary gaze, when uncorrected, and when corrected with spectacles and contact lenses. Measures were made every 5\u00b0 out to 30\u00b0 horizontally in nasal and temporal retina and analysed as power vectors (\n                      <jats:italic>M<\/jats:italic>\n                      ,\n                      <jats:italic>J<\/jats:italic>\n                      <jats:sub>0<\/jats:sub>\n                      , and\n                      <jats:italic>J<\/jats:italic>\n                      <jats:sub>45<\/jats:sub>\n                      ). Partial coherence interferometry measures of eye size were also made on\u2010axis and off\u2010axis at 10\u00ba and 20\u00ba in nasal and temporal retina.\n                    <\/jats:p>\n                    <jats:p>\n                      <jats:bold>Results:\u2002<\/jats:bold>\n                      Subjects (mean age 24; range 19\u201329\u2003years) had an average on\u2010axis mean\u2010sphere refraction of \u22126.33\u2003\u00b1\u20030.31 D (mean\u2003\u00b1\u20031 S.E.) and an average axial eye length of 25.99\u2003\u00b1\u20030.20\u2003mm. The average relative peripheral refraction (RPR) for all subjects across all eccentricities was hyperopic when uncorrected (+0.90\u2003\u00b1\u20030.14 D) and also when corrected with spectacles (+1.01\u2003\u00b1\u20030.13 D) but changed to a myopic RPR when corrected with contact lenses (\u22121.84\u2003\u00b1\u20030.61 D). There was a highly significant effect of correction on peripheral refraction (\n                      <jats:italic>p<\/jats:italic>\n                      \u2003&lt;\u20030.0001).

Correcting the same eyes with conventional spherical soft contact lenses results in significant myopic defocus in the peripheral retina. These results corroborate the general findings of earlier studies and the predictions of optical modelling by others. If the refractive status of the peripheral retina does influence myopia progression, then these results suggest that myopia progression should be slower with conventional contact lens wear than with conventional spectacle wear. However, previous studies comparing myopia progression with conventional spectacles and conventional contact lenses have reported no such difference.\n                    <\/jats:p>\n
