Abstract
Purpose: :
To compare visual outcomes with bilateral implantation of an aspheric diffractive multifocal and an aberration-free accommodating IOL post-cataract surgery.
Methods: :
Prospective, six-month comparison of 40 patients scheduled to undergo bilateral phacoemulsification and implantation of posterior intraocular lenses: aspheric diffractive TECNIS® multifocal (T) and CRYSTALENS® AO accommodating (C) IOLs.
Results: :
Mean preoperative SE (T: -0.237 ± 2.2 D, C: 0.56 ± 1.5 D). At Month 6, uncorrected near mean visual acuity were (LogMAR) (T: 0.06, C: 0.24), P=0.024. Both lenses provided equivalent mean acuities at distance (mean 0.05) and intermediate (mean 0.2). Percentage of patients satisfied with their vision during the day (87%, 82%), at night (84%, 82%), and overall (86%, 78%), for the aspheric diffractive multifocal and accommodating IOLs, respectively. Percentage of patients who reported that their reading distance was perfect (T: 94%, C: 50%), P=0.042.
Conclusions: :
The aspheric diffractive multifocal IOL showed satisfactory visual outcomes and a high degree of patient satisfaction at various distances and lighting conditions. A significantly higher percentage of the aspheric diffractive multifocal IOL patients than accommodating IOL patients reported being satisfied with their vision during the day, at night, and overall.
