NCT00759668

Brief Summary

The purpose of the study is:

  • to compare visual parameters (Subjective refraction and Visual Acuity (VA)) and safety (tilt, decentration and posterior chamber opacification (PCO)) in a prospective series of 40 patients after bilateral implantation of AcrySof Natural ReSTOR (Model SN60D3) or AcrySof Natural Monofocal (Model SN60AT)
  • to assess patient satisfaction before and after implant

Outcome Measures

Primary Outcomes (6)

  • Near Best Corrected Visual Acuity (BCVA) - Binocular

    Percentage of patients with Near Visual Acuity (VA) ≥ 6.5/10 (≤ 0.18 LogMAR) at visit 8 (six months after implantation of the 2nd eye). This test was conducted binocularly and with best correction. The effect of treatment was tested by Chi-square test. VA is acuteness or clearness of vision, which is dependent on the sharpness of the retinal focus within the eye and the sensitivity of the interpretative faculty of the brain. VA is measured in logMAR which is the "logarithm of the minimum angle of resolution". A lower logMAR value indicates better VA.

    6 months after second eye implantation

  • Near Uncorrected Visual Acuity (UCVA) Binocular

    Percentage of patients with Near Visual Acuity (VA) ≥ 6.5/10 (≤ 0.18 LogMAR) at visit 8 (six months after implantation of the 2nd eye). This test was conducted binocularly and with no correction. The effect of treatment was tested by Chi-square test. VA is acuteness or clearness of vision, which is dependent on the sharpness of the retinal focus within the eye and the sensitivity of the interpretative faculty of the brain. VA is measured in logMAR which is the "logarithm of the minimum angle of resolution". A lower logMAR value indicates better VA.

    6 months after second eye implantation

  • Near Best Corrected Visual Acuity Left Eye (BCVA LE)

    Percentage of patients with Near Visual Acuity (VA) ≥ 6.5/10 (≤ 0.18 LogMAR) at visit 8 (six months after implantation of the 2nd eye). This test was conducted monocularly (left eye only) and with best correction. The effect of treatment was tested by Chi-square test. VA is acuteness or clearness of vision, which is dependent on the sharpness of the retinal focus within the eye and the sensitivity of the interpretative faculty of the brain. VA is measured in logMAR which is the "logarithm of the minimum angle of resolution". A lower logMAR value indicates better VA.

    6 months after second eye implantation

  • Near Uncorrected Visual Acuity Left Eye (UCVA LE)

    Percentage of patients with Near Visual Acuity (VA) ≥ 6.5/10 (≤ 0.18 LogMAR) at visit 8 (six months after implantation of the 2nd eye). This test was conducted monocularly (left eye only) and with no correction. The effect of treatment was tested by Chi-square test. VA is acuteness or clearness of vision, which is dependent on the sharpness of the retinal focus within the eye and the sensitivity of the interpretative faculty of the brain. VA is measured in logMAR which is the "logarithm of the minimum angle of resolution". A lower logMAR value indicates better VA.

    6 months after second eye implantation

  • Near Best Corrected Visual Acuity Right Eye (BCVA RE)

    Percentage of patients with Near Visual Acuity (VA) ≥ 6.5/10 (≤ 0.18 LogMAR) at visit 8 (six months after implantation of the 2nd eye). This test was conducted monocularly (right eye only) and with best correction. The effect of treatment was tested by Chi-square test. VA is acuteness or clearness of vision, which is dependent on the sharpness of the retinal focus within the eye and the sensitivity of the interpretative faculty of the brain. VA is measured in logMAR which is the "logarithm of the minimum angle of resolution". A lower logMAR value indicates better VA.

    6 months after second eye implantation

  • Near Uncorrected Visual Acuity Right Eye (UCVA RE)

    Percentage of patients with Near Visual Acuity (VA) ≥ 6.5/10 (≤ 0.18 LogMAR) at visit 8 (six months after implantation of the 2nd eye). This test was conducted monocularly (right eye only) and with no correction. The effect of treatment was tested by Chi-square test.

Limitations and Caveats

Visual acuity data were collected in different units (i.e. c, twentieth, decimal, Jaeger) and were converted to LogMAR after inclusion in the database. This led to inevitable approximations of the data.
