AcrySof ReSTOR Model SN60D3
  • Apodized diffractive structure 3.6 mm center
  • Refractive in periphery
  • Incorporates 4.0 add at lens plane equaling 3.2

The ReSTOR Aspheric IOL (SN6AD3) is designed with
negative spherical aberration
4
Patients and Methods
  • Prospective study aspheric ReSTOR
  • 15 patients, 30 eyes with cataract
  • Bilateral implantation within 2 weeks
  • 8-14 weeks follow-up
  • Mean age 67 8.0 years (range 52-81)
  • Comparison with historical standard ReSTOR
    (SN60D3) group

5
Outcome Measures
  • Patients were examined monocularly and
    binocularly
  • ETDRS visual acuity charts
  • logMAR visual acuity transferred to Snellen UCDVA
    and BCDVA
  • Near visual acuity transformed into Snellen
    values
  • Contrast sensitivity CSV-1000

Use of SpectaclesAspheric ReSTOR IOL
  • Reading glasses 0/15
  • Distance glasses 0/15
  • 3/30 eyes scheduled for LASEK
  • Computer glasses 2/15

Adverse Effects
  • 3/30 eyes scheduled for YAG capsulotomy
  • 3/30 eyes scheduled for LASEK
  • 1/30 re-operated for decentration
  • 1/30 IOL exchange for postoperative ametropia
  • No disturbing glare or halos

12
Conclusions
  • Preliminary data of the aspheric ReSTOR IOL
    (SN6AD3)
  • Provides excellent near and distant VA
  • Mean monocular UCNVA 0.96
  • No glasses for near or distant vision
  • 2/15 patients computer glasses
  • No disturbing glare or halos
  • Higher contrast sensitivity as compared to
    standard ReSTOR
