Each subject willchoose to receive the same lens type in both eyes, either the TECNIS Toric IOLs(Models ZCT300 and/or ZCT400), or the non-toric control IOL (TECNIS Model ZCB00).VISIT SCHEDULE: All subjects are intended to have bilateral cataract surgery with thesecond-eye surgery occurring within approximately 1 month of the first-eye surgery( 60 days). Two postoperative study visits will be conducted; at 1 monthVersion 3.08PR/TIOL-202-TPAS

ABBOTT MEDICAL OPTICS INC.CONFIDENTIAL(30-60 days after the second-eye surgery) and at 6 months (120-180 days after thesecond-eye surgery) for both eyes together. However, subjects who underwent an IOLrepositioning procedure due to IOL misalignment or who reported a severe visualdistortion at 6 months will return for a final visit at 1 year (330-420 days after thesecond-eye surgery) postoperatively.PREOPERATIVE PROCEDURES: Following informed consent, a subject questionnairefor determination of visual distortions will be administered (Patient Reported VisualDistortion Questionnaire; PRVDQ). Demographic, general preoperative and operativeinformation will be collected from routine cataract evaluation examinations and surgicalreports.POSTOPERATIVE PROCEDURES: At the 1-month visit, a spectacle and/or contactlens prescription will be offered to each subject. If the subject has a spontaneous reportof any of the 5 defined visual distortion items of interest or of blurred or hazy vision, thequestionnaire will be administered and, for subjects with toric IOLs, keratometry and toricIOL axis measurements will be performed.At the 6-month visit, the postoperative procedures will include a subject questionnaire(Patient Reported Visual Distortion Questionnaire; PRVDQ) for determination of visualdistortions, biomicroscopic slit-lamp examination for any adverse events and, forsubjects with toric IOLs, determination of toric IOL axis position and keratometry.If outside of a scheduled study visit, a subject has a spontaneous report of; 1) any of the5 defined visual distortion items of interest or 2) blurred or hazy vision at 1 monthpostoperatively or later, the PRVDQ questionnaire will be administered and, for subjectswith toric IOLs, keratometry and toric IOL axis measurements will be performed. Examdetails will be documented on an unscheduled visit form.If a subject reported a severe visual distortion in the questionnaire or experienced anocular adverse event at any scheduled or unscheduled study visit, uncorrected distancevisual acuity, best corrected distance visual acuity, manifest refraction, slit-lampexamination and intraocular pressure measurements will also be performed.A 1-year examination will be required only if the subject reports a severe visual distortionat the 6-month examination or experienced an IOL repositioning procedure (due to IOLmisalignment during the study).If a serious or device-related adverse event occurs at or prior to the 6-month visit, detailsof the event will be collected at the time of the event using an adverse event form. If theadverse event is an IOL misalignment resulting in an IOL repositioning procedure, thequestionnaire is to be administered prior to the repositioning procedure to collectinformation regarding visual distortions, and, for subjects with toric IOLs, keratometryand toric IOL axis measurements will be performed prior to the repositioning procedureto collect data regarding the IOL misalignment.Version 3.09PR/TIOL-202-TPAS

ABBOTT MEDICAL OPTICS INC.CONFIDENTIALDATA ANALYSIS:The rate of severe visual distortions as defined by the 5 items listed under primaryendpoint will be compared between bilaterally-implanted toric IOL subjects andbilaterally-implanted non-toric control IOL subjects at 6 months. The frequency andproportion of toric and non-toric control subjects with severe visual distortions will bereported. Results between the toric IOL and the non-toric control IOL groups will beevaluated using a non-inferiority approach with a non-inferiority margin of 10%.Assessment of toric IOL axis misalignment will be compared to reports of visualdistortions.The frequency and proportion of secondary surgical interventions due to IOLmisalignment, as well as rates for other adverse events or medical and lens findings, willbe reported by treatment group. Evaluation at 6 months will include reporting bytreatment groups the incidence of all adverse events, including severity for seriousadverse events and adverse device effects.Visual distortion findings, adverse events and medical/lens findings at one year will bereported for subjects who experienced a repositioning procedure during the study or forsubjects who were reported with severe visual distortions at the 6-month visit.2.0BACKGROUND AND PURPOSE OF STUDYIt is estimated that 35% of cataract patients have 1.00 diopter of corneal astigmatism1with 15%-20% having 1.5 D of corneal astigmatism.1,2 Although there are variousmodalities to reduce the amount of astigmatism during cataract surgery (e.g., limbalrelaxing incisions, etc.), toric IOLs are now commonly used for correction of aphakia andpre-existing ocular astigmatism. On April 15, 2013, Abbott Medical Optics (AMO)received USA FDA approval (P980040/S039) for the TECNIS 1-Piece Toric IOL, ModelsZCT150, ZCT225, ZCT300 and ZCT400 for the visual correction of aphakia and preexisting corneal astigmatism of one diopter or greater.In the IDE registration trial of the TECNIS 1-Piece Toric IOL (G090251), rotationalstability was demonstrated and there were minimal subject complaints of visualdistortions; however, there is the potential, particularly in the case of toric IOLs thatcorrect for higher amounts of corneal astigmatism, that patients may experience spatialdistortions related to axis misalignment, e.g., whether objects appear tilted ormisshapen, etc. As a condition of approval, this post-approval study will be conducted toVersion 3.010PR/TIOL-202-TPAS

Subjects will chooseto be bilaterally implanted with either 1) the TECNIS 1-Piece Toric IOLs, Model ZCT300and/or ZCT400, or 2) the TECNIS Monofocal Model ZCB00 non-toric control IOL,according to subject preference.5.0CLINICAL HYPOTHESISThe rate of severe visual distortions for the TECNIS 1-Piece Toric IOL Models ZCT300and ZCT400 will be less than 10 percentage points above that for the non-toric controlIOL group with the same level of preoperative corneal astigmatism.6.0STUDY ENDPOINTSStudy endpoints will be evaluated at 6 months postoperatively.PRIMARY ENDPOINTThe primary endpoint is the rate of severe visual distortions based on data collectedfrom a self-administered subject questionnaire (PRVDQ).Version 3.011PR/TIOL-202-TPAS

ABBOTT MEDICAL OPTICS INC.CONFIDENTIALThe rate of severe visual distortions is defined as the percentage of subjects who reporta severe visual distortion under overall circumstances at 6 months postoperative for anyof the following 5 visual distortion items of interest:ooooolines that slant, tilt, split or separateflat surfaces appearing curvedobjects appearing further away or closer than they actually areobjects appearing to have a different size or shapephysical discomfort related to visionDistortions will be assessed using the overall circumstance reply at the6-month visit. The frequency and proportion of subjects reporting one ormore of these items as severe will be used to determine the rate ofsevere visual distortions.Success criteria: Rates of severe visual distortions for the TECNIS 1-PieceToric IOL group will be less than 10 percentage points aboverates for the non-toric control IOL group.OTHER ENDPOINTS Ratings of individual items included on the visual distortion questionnaire Rates of IOL repositioning procedures (secondary surgical intervention) due toIOL misalignment Rates of other adverse events7.0STUDY PRODUCTS7.1INTRAOCULAR LENSESThe TECNIS 1-Piece Toric IOL, Models ZCT300 and ZCT400, and the TECNIS 1-PieceModel ZCB00 non-toric control IOL are posterior chamber, 1-piece, aspheric,hydrophobic acrylic foldable IOLs and are to be implanted in the capsular bag followingcataract extraction. Both the TECNIS 1-Piece Toric IOLs and the TECNIS 1-Piecemonofocal non-toric IOL, Model ZCB00, have an anterior aspheric optic surface and aspherical posterior optic surface; however, the TECNIS 1-Piece Toric IOLS have anadditional toric feature on the anterior optic surface to correct for ocular astigmatism.The TECNIS 1-Piece Toric IOLs are indicated for the visual correction of aphakia andpre-existing corneal astigmatism of one diopter or greater in adult patients with andwithout presbyopia in whom a cataractous lens has been removed by extracapsularcataract extraction, and who desire improved uncorrected distance vision, reduction inresidual refractive cylinder, and increased spectacle independence for distance.
