| Objective: To compare the high order aberrations of cataract eyeswith different intraocular lenses (IOL) implantation and to improve opticaldesigns of IOLs with better retinal image quality. Methods: 47 patients (50 eyes) were selected randomly who acceptedphacoemulsification and were implanted IOLs. Any other eye disease andwhole body disease have been excluded. They were divided into twogroups according to different IOLs. In group A, the 5.75mm opticaldiameter Hydrophilic Acrylic IOL were implanted into 35 eyes of 35patients ; in group B, the 6.0mm optical diameter Hydrophilic Acrylic IOLwere implanted into 15 eyes of 15 patients. And 3 patients of group A alsowere implanted 6.0mm optical diameter Hydrophilic Acrylic IOL in theiranother eyes. All the operations were done by one person and the otherfactors that can affect the result such as age have been deleted. Theaberrations of all these patients after surgery were checked and analyzedwith wavelight analyzer. Results: 1. For 4.0mm pupil, the average RMSh values of thesegroups were as follow: 0.36±0.11μm (group A), 0.30±0.15μm (group B).For 5.0mm pupil, the average RMSh values of these groups were as follow:0.57±0.12μm (group A), 0.61±0.17μm (group B). For 6.0mm pupil, theaverage RMSh values of these groups were as follow: 0.84±0.15μm (groupA), 0.89±0.20μm (group B). For 7.0mm pupil, the average RMSh values ofthese groups were as follow: 1.74±0.19μm (group A), 1.42±0.22μm (groupB). 2. For 4.0mm 5.0mm 6.0mm and 7.0mm pupil, the average RMShvalues were not significantly different between group A and group B(p>0.05). Conclusions: 1. the larger the pupil is ,the higher the RMSh valuesare in the eyes with IOL. 2. For 4.0mm 5.0mm 6.0mm and 7.0mm pupil,the average RMSh values of patients implanted 5.75mm optical diameterHydrophilic Acrylic IOL were not significantly different with those ofpatients implanted 6.0mm optical diameter Hydrophilic Acrylic IOL. |
