lass=""h4"">Setting
Vissum-Instituto de Oftalmolxf3;gico de Alicante, Alicante, Spain, and University Eye Clinic, Paracelsus Medical University, Salzburg, Austria.
lass=""h4"">Design
Comparative case series.
lass=""h4"">Methods
Patients had bilateral phacoemulsification and implantation of Acri.Smart 48S monofocal, Acrysof Restor SN6AD3 apodized multifocal, Acri.LISA 366D diffractive multifocal, or Rezoom refractive multifocal IOLs. Bilateral reading performance with and without near correction was evaluated preoperatively and postoperatively using the Salzburg Reading Desk.
lass=""h4"">Results
The study comprised 304 eyes of 152 patients 51 to 90 years old. All groups had a significant improvement in uncorrected and corrected distance visual acuities postoperatively (P≤.01). The apodized multifocal and diffractive multifocal groups had significantly better uncorrected reading acuity than the monofocal and refractive multifocal groups 1 month and 6 months postoperatively (P<.01). Uncorrected reading speed was significantly worse in the refractive multifocal group than in the monofocal group at 1 month (P<.01). The monofocal group had the greatest uncorrected reading distance at 1 month and 6 months (P<.01).
lass=""h4"">Conclusion
Multifocal IOLs with a diffractive component provided a comparable reading performance that was significantly better than the one obtained with refractive multifocal and monofocal IOLs.
