Scleral buckling surgery frequently induces geometrical change of eyeball contour, so the axial length and refraction may also be changed. We prospectively collected 33 cases of rhegmatogenous retinal detachment with fovea attached to evaluate the change of axial length and refraction after scleral buckling. The follow up peroid was at least 6 months. For all cases after scleral buckles, it caused an average increase of axial length as 0.41 mm (p<0.01) and refractive change of -0.32D (p<0.01). For encircling buckles subgroup, it caused an average increase of axial length as 0.74 mm (p<0.01) and refractive change of -2.79D (p<0.01). For non-encircling buckles subgroup, it caused an average increase of axial length as 0.14 mm (p=0.01) and refractive change of -0.09D (p=0.39). Eyes with encircling buckles have significant more change in axial length (p<0.01) and myopia shifting (p<0.01) than eyes without encircling buckles.
