Limitations with Vision for Near, Distance, and Social Activities:A Comparison Among Three Models of Presbyopia-Correcting IOLs Trevor Woodhams, MD Financial Disclosure: Alcon sponsored the study and provided statistical and presentation support.
Purpose • To evaluate limitations with vision for near, distance, and social activities, as reported by patients with bilateral aspheric apodized diffractive multifocal IOLs (IQ ReSTOR +3.0 D IOLs, Alcon), bilateral aspheric accommodative IOLs (Crystalens AO; Bausch & Lomb), or bilateral spherical accommodative IOLs (Crystalens HD; Bausch & Lomb).
Methods • A prospective, patient-masked, multicenter study • patients with bilateral cataracts • <1.0 D of corneal astigmatism • Randomized to receive implantation of bilateral multifocal IOLs, bilateral AO IOLs, or bilateral HD IOLs • 3-mo interim results
Demographics No significant between-group differences.
Endpoints Evaluated • Preoperatively and at 3 months postoperative, a validated questionnaire (Cataract TyPE) was distributed • Composites scores of questions about various activities were used to assess limitations with uncorrected: • near-vision function (5 questions) • distance-vision function (7 questions) • vision for social activities (5 questions) • Response options ranged from 0 (no limitation) to 4 (extreme limitation), or could be marked as not applicable
Limitations with Uncorrected Vision at Near Distance @ 3-month visit Extreme limitation Least limitation in near vision activities with the IQ ReSTOR +3.0 D IOL, followed by HD IOL, then AO IOL. Less Limitation * None *P<.02; IQ ReSTOR +3.0 D IOL had least limitation among IOLs
Limitations with Uncorrected Vision at Far Distance @ 3-month visit Extreme limitation Least limitation in distance vision activities with the IQ ReSTOR +3.0 D, followed by AO IOL, then HD IOL. Less Limitation * None *P=.01; IQ ReSTOR +3.0 D IOL had least limitation among the IOLs
Limitations with Uncorrected Vision during Social Activities @ 3-month visit Extreme limitation Least limitations in social activities with the IQ ReSTOR +3.0 D IOL, followed by AO IOL, then HD IOL. * * * Less Limitation None *P<.05; between-group differences favoring IQ ReSTOR +3.0 D IOL
Conclusions • Three months after bilateral implantation of presbyopia-correcting IOLs, limitations with uncorrected vision for: • Near distance were least for the IQ ReSTOR+3.0 D IOL group, followed by the HD IOL group, and greatest for the AO IOL group • Far distance were least for the IQ ReSTOR +3.0 D IOL group, followed by the AO IOL group, and greatest for the HD IOL group • Social activity were least for the IQ ReSTOR +3.0 D IOL group, followed by the AO IOL group, and greatest for the HD IOL group
