Purpose:
To compare bilateral reading performance within the first 6 months after implantation of 4 intraocular lens (IOL) models.
Setting:
Vissum-Instituto de Oftalmológico de Alicante, Alicante, Spain, and University Eye Clinic, Paracelsus Medical University, Salzburg, Austria.
Design:
Comparative case series.
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.
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).
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.
