visual outcomes of aspheric iol (acrysof iq) versus spheric iol (sensar) implantation

چکیده
purpose: to compare acrysof iq and sensar intraocular lens (iols) in terms of spherical aberration and contrast sensitivity. methods: thirty-four eyes of 34 patients undergoing phacoemulsification cataract surgery were randomly assigned for implantation of acrysof iq or sensar iols. three months postoperatively, best-corrected visual acuity (bcva), spherical aberration (with 4 and 6 mm pupil diameters) and contrast sensitivity under photopic and mesopic conditions at spatial frequencies of 1, 2, 5, 10 and 20 cycles per degree (cpd) were determined. results: patients included 21 male (61.8%) and 13 female (38.2%) subjects. mean bcva was 0.083±0.071 logmar in the iq group and 0.145±0.097 logmar in the sensar group (p=0.079). spherical aberration with both 4 and 6 mm pupil diameters in the iq group was less than in the sensar group (0.183±0.107 µm vs 0.354±0.138 µm, p<0.001 and 0.26±0.096 µm vs 0.435±0.152 µm, p=0.002; respectively). contrast sensitivity was higher in the iq group at 1, 2, 5, 10 and 20 cpd under photopic conditions and at 1, 10 and 20 cpd under mesopic conditions (p<0.02). conclusion: acrysof iq aspheric iol seems to have better visual outcomes regarding spherical aberration and contrast sensitivity as compared to spheric sensar iol.

We interpreted the clinical data from 16 eyes with a 3M multifocal implant and compared them with data from 16 monofocal implants with the same follow-up period. The multifocal implant has several disadvantages: a lower initial visual acuity, a higher frequency of posterior synechiae, and slightly more difficult ophthalmoscopy than with conventional lenses. The great advantage of the multifocal...
