Objective To investigate the changes of wavefront aberrations in keratoconus corrected with rigid gas permeable contact lens (RGPCL).Methods It was a prospective case-control study.Twenty-five patients (43 eyes) confirmed by corneal topography as keratoconus were corrected with RGPCL.Their corrected visual acuity (VA) and wavefront aberrations were detected by iTrace dynamic laserefraction before and after wearing RGPCL for 2 weeks.Lower-order abberations LOAs,higher-order abberation HOAs,coma,spherical and trefoil were measured.The results measured were compared using paired samples t test.Results There were statistic differences in total ocular wavefront aberrations,LOAs,HOAs,coma and trefoil.Total ocular wavefront aberrations were reduced from 9.12±4.20 μm to 1.67±0.92 μm after wearing RGPCL (t=9.062,P＜0.01); LOAs were reduced from 8.88-±3.90 μm to 1.37±0.75 μm after wearing RGPCL (t=9.507,P＜0.01); HOAs were reduced from 1.90±0.14 μm to 0.79±0.21 μm after wearing RGPCL (t=2.473,P＜0.05); coma were reduced from 0.99±0.15 μm to 0.30±0.18 μm after wearing RGPCL (t=2.364,P＜0.05); trefoil were reduced from 0.92±0.19 μm to 0.22±0.14 μm after wearing RGPCL (t=2.757,P＜0.05).There were no statistics differences in spherical abberation.Spherical abberation were reduced from 0.54±0.25 μm to 0.32±0.27 μm after wearing RGPCL (t=1.239,P＞0.05).Conclusion Keratoconus patients with RGPCL can reach satisfying corrected visual acuity and visual quantity.Total ocular wavefront aberrations were significant reduced after wearing RGPCL.
