Arms Assigned Interventions
Experimental: IQ Toric IOL
AcrySof IQ Toric intraocular lens (IOL) randomly assigned to one eye, with AcrySof IQ Aspheric IOL with Limbal Relaxing Incision (LRI) procedure in the fellow eye for contralateral implantation.
Device: AcrySof IQ Toric IOL
AcrySof IQ Toric intraocular lens implanted in the capsular bag of the eye during cataract surgery. The IOL is intended for the lifetime of the patient.
Other Names:
  • AcrySof IQ Toric IOL Model SN6AT3
  • AcrySof IQ Toric IOL Model SN6AT4
  • AcrySof IQ Toric IOL Model SN6AT5
Active Comparator: IQ Aspheric IOL + LRI
AcrySof IQ Aspheric intraocular lens (IOL) with Limbal Relaxing Incision (LRI) procedure randomly assigned to one eye, with AcrySof IQ Toric IOL in the fellow eye for contralateral implantation
Device: AcrySof IQ Aspheric IOL
AcrySof IQ aspheric intraocular lens implanted in the capsular bag of the eye during cataract surgery. The IOL is intended for the lifetime of the patient.
Other Name: AcrySof IQ Aspheric IOL Model SN60WF
Procedure: Limbal Relaxing Incision (LRI)
An incision was made at the corneal-limbal junction during cataract surgery for the purpose of relaxing corneal curvature, ie., correcting astigmatism.
