Abstract
Purpose: :
To analyze the outcomes for visual acuity in patients after cataract surgery with bilateral diffractive intraocular lens (RestorTM) compared to patients with multifocal diffractive (RezoomTM) and multifocal asferic intraocular lens (TecnisTM).SETTING: OFTALMO SALUD Instituto de Ojos, Lima, Peru.
Methods: :
This prospective, randomized study involved 80 patients with bilateral cataracts. Each patient underwent standard phacoemulsification cataract surgery on both eyes with 40 consecutive patients (80 eyes) receiving bilateral aspheric bifocal +3.00D model (AcrySof ReSTOR SN6AD1) intraocular lens (IOLs) and 40 patients (80 eyes) receiving ReZoom IOL (Advanced Medical Optics) in one eye and Tecnis Multifocal in the second eye. The inclusion criteria were no eye disease that could potentially result in decreased postoperative visual acuity or contrast sensitivity and preoperative astigmatism less than 1,5D. Pre- and postoperative (at 1 month) distance and near uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), as well as spectacle dependence for near, intermediate and far vision, unwanted visual symptoms and patients satisfaction were tested and compared.
Results: :
There were no statistically significant differences between distance UCVA pre and postoperatively comparing both groups. All patients in the Restor/Restor and Rezoom/Tecnis group achieved J3 or better Near UCVA postoperatively. 37 patients (92,5%) in the Rezoom/Tecnis group achieved J1-J2 vs 38 patients (95%) in the Restor/Restor group, instead there was no statistical significant difference (p > .05). 32 patients (80%) in the Restor/Restor group and 33 patients ( 82,5%) in the Tecnis/Rezoom group achieved full independence from spectacle wear. More than 95% in both group stated that they would choose to have the same lens implanted again.
Conclusions: :
Patients implanted with Rezoom/Tecnis or Restor/Restor group showed equivalent postoperative distance and near UCVA and BCVA and excellent spectacle independence.
