Abstract
To assess high order and spherical aberrations results of hydrophobic acrylic AMO Sensar AR40E and hydrophobic acrylic Alcon AcrySof SA60AT intraocular lenses after implantation in cases with bilateral cataract. Cases diagnosed as bilateral cataract were included in the study and preoperative aberration measurements were recorded by using Nidek OPD SCAN-ARK 1000. Groups were created by implanting AMO Sensar AR40E to one eye of the patients, while Alcon AcrySof SA60AT into the other in a prospective and randomized manner. Aberration measurements were recorded after one and two months of surgery. Overall, 40 eyes in 20 patients (11 women and 9 men) were included in the study. All patients underwent bilateral phacoemulsification surgery due to cataract. There were 20 eyes in both groups. Mean age was 62.4 (range: 31-82) years. There was no significant difference in aberrations recorded before surgery and one and two months after surgery in both groups. (p<0.05). There was no difference among spherical intraocular lenses used in this study.
Highlights
Cataract is one of the main preventable causes of blindness.[1,2,3] Surgery is still the only cure option in cataract management.[4]
Positive spherical aberration caused by cornea is neutralized by negative spherical aberration in the lens
Inter-group or intra-group comparisons were performed for high-order (HO) and spherical aberration values recorded before surgery and on the month 1 and 2 after surgery
Summary

Spherical intraocular lenses (IOLs) cause spherical aberration in pseudophakic eyes, where it has little effect on other aberrations. Aberrations vary depending on the dioptric power, optical diameter, material, design and RI of the IOLs. In the phakic eyes, cornea and lens are the two optical elements determining quality of retinal image. Positive spherical aberration caused by cornea is neutralized by negative spherical aberration in the lens. In elderly individuals, shift towards positive in spherical aberration related to lens increases total aberration of the eye.[8,9]. The aim of this study was to assess the optical aberration results of hydrophobic acrylic AMO Sensar AR40E and hydrophobic acrylic Alcon AcrySof SA60AT intraocular lenses after implantation in cases with bilateral cataract
