M-CHARTS (MC) was used to evaluate metamorphopsia. Retinal distances were measured between two sets of retinal vessel bifurcations that cross the macula vertically and horizontally near and distal to the macula using OCTA 3x3 mm en face images. The rate of change in retinal distance was defined as retinal displacement%. Basal and minimum MH diameters and retinal thicknesses were measured using Spectralis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The vertical and horizontal MC scores improved postoperatively (\n                      <jats:italic>P<\/jats:italic>\n                      &lt;0.001).
