tecnis tm multifocal multicentre trial evaluation parameters
TecnisTM Multifocal Multicentre Trial - Evaluation Parameters
  • Goal to enroll 250 patients to be bilaterally implanted with the Tecnis Multifocal IOL, at 25 sites
  • Method:
    • Pre and post-op patient qualitative questionnaires on freedom from glasses at different distances, and on dysphotopic phenomenom
    • Pre and post-op surgeon qualitative and quantitative questionnaires on refraction and uncorrected visual acuity for Far, Intermediate and Near distance
    • Assessments at pre-op, one and six months post-op
patient selection criteria
Patient Selection Criteria

Male and female adult patients with presbyopia for which bilateral cataract surgery or clear lensectomy and posterior chamber IOL implantation is indicated.

Good candidate for multifocal vision, i.e. motivated, desires spectacle independence and understands the trade-off of improved near vision to possible unwanted visual sensations.

Visual potential of 20/25 or better in each eye after cataract extraction and IOL implantation.

Patient dissatisfaction with their uncorrected or best corrected vision such that they desire surgery.

Naturally dilated pupil size (in dim light) > 3.5 mm (with no dilation medications) for both eyes.

IOL power available for both eyes being treated

patient exclusion criteria
Patient Exclusion Criteria

Patients with history of prior refractive surgery.

Patient has ocular or systemic disease, or ocular trauma that may confound the outcome; (e.g. uncontrolled diabetes mellitus, prior ocular surgery, recurrent inflammatory conditions, or macular degeneration).

Capsule or zonular abnormalities that may affect postoperative centration or tilt of the lens (e.g. severe pseudoexfoliation syndrome, Marfan’s syndrome).

Pupil abnormalities that prevent pupil from dilating at least 3.5 mm under mesopic/scotopic conditions.

Patients with forme fruste keratoconus or keratoconus.

Patients with visually significant macula or retina disease

  • # of patients having completed pre-op questionnaire: 136
  • # of patients having completed 1 month post-op follow-up: 78
  • # of patients having completed 3 month post-op follow-up: 63

Patient Reading Distance Comfort:

Very Comfortable

spectacle independence
Spectacle Independence:

Almost Always

Never

slide12
Post-op target refraction was achieved and stable to 3 month visit

Hyperopic patients tend to have better uncorrected and distance corrected VA for distance, intermediate and near

Hyperopic patients have more comfortable reading vision and greater spectacle independence
