摘要

AIM:To evaluate the refractive correction for standard automated perimetry(SAP) in eyes with refractive multifocal contact lenses(CL) in healthy young participants.METHODS:Twenty-nine eyes of 29 participants were included.Accommodation was paralyzed in all participants with 1% cyclopentolate hydrochloride.SAP was performed using the Humphrey SITA-standard 24-2 and 10-2 protocol under three refractive conditions:monofocal CL corrected for near distance(baseline);multifocal CL corrected for distance(m CL-D);and m CL-D corrected for near vision using a spectacle lens(m CL-N).Primary outcome measures were the foveal threshold,mean deviation(MD),and pattern standard deviation(PSD).RESULTS:The foveal threshold of m CL-N with both the 24-2 and 10-2 protocols significantly decreased by 2.2-2.5 d B(P<0.001),while that of m CL-D with the 24-2 protocol significantly decreased by 1.5 d B(P=0.0427),as compared with that of baseline.Although there was no significant difference between the MD of baseline and m CL-D with the 24-2 and 10-2 protocols,the MD of m CL-N was significantly decreased by 1.0-1.3 d B(P<0.001) as compared with that of both baseline and m CL-D,with both 24-2 and 10-2 protocols.There was no significant difference in the PSD among the three refractive conditions with both the 24-2 and 10-2 protocols.CONCLUSION:Despite the induced mydriasis and the optical design of the multifocal lens used in this study,our results indicated that,when the dome-shaped visual field test is performed with eyes with large pupils and wearing refractive multifocal CLs,distance correction without additional near correction is to be recommended.
