effect of total higherorder aberrations on accommodation in pseudophakic eyes purpose to analyze the effect of total higherorder aberrations hoas on the range of accommodation in pseudophakic eyes and the size of nearvision optotypessetting department of ophthalmology nara medical university nara japanmethods the study comprised 30 patients 44 eyes who were diagnosed with cataract at nara university of medical science hospital and municipal oyodo hospital inclusion criteria included no other eye disorder and a best corrected distance acuity of 2020 or better 1 month after cataract surgery all patients had smallincision phacoemulsification followed by inthebag implantation of a monofocal intraocular lens sa60at alcon all incisions were selfsealing accommodation in pseudophakic eyes was measured by the lensloading method in an examination room under constant illumination ocular hoas were measured using the kr9000pw hartmannshack wavefront analyzer topconresults the mean patient age was 758 years 54 sd range 64 to 83 years the pearson correlation coefficient r showed a significant positive correlation between the range of accommodation and z7 vertical coma for a 40 mm pupil using the 10 nearvision optotype there was a significant negative correlation between the range of accommodation and z12 spherical aberration for a 40 mm pupil using the 10 nearvision optotype r 311 p 040 for z7r 365 p 015 for z12 no other parameter was significantly correlated with the range of accommodationconclusions measurement of accommodation in pseudophakic eyes by the lensloading method using the 10 nearvision optotype showed that eyes with larger vertical coma aberrations achieved a larger range of accommodation in contrast eyes with larger spherical aberrations had smaller amounts of accommodation the size of the nearvision optotype may affect accommodation analysis in pseudophakic eyes
