Visual Function and Patient Satisfaction After Bilateral Implantation of AcrySof Natural ReSTOR (Model SN60D3) or AcrySof Natural Monofocal (Model SN60AT) - Full Text View

Purpose

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

Primary Outcome Measures:

Near Best Corrected Visual Acuity (BCVA) - Binocular [ Time Frame: 6 months after second eye implantation ] [ Designated as safety issue: No ]
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.
Near Uncorrected Visual Acuity (UCVA) Binocular [ Time Frame: 6 months after second eye implantation ] [ Designated as safety issue: No ]
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.
Near Best Corrected Visual Acuity Left Eye (BCVA LE) [ Time Frame: 6 months after second eye implantation ] [ Designated as safety issue: No ]
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.
Near Uncorrected Visual Acuity Left Eye (UCVA LE) [ Time Frame: 6 months after second eye implantation ] [ Designated as safety issue: No ]
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.
Near Best Corrected Visual Acuity Right Eye (BCVA RE) [ Time Frame: 6 months after second eye implantation ] [ Designated as safety issue: No ]
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.
Near Uncorrected Visual Acuity Right Eye (UCVA RE) [ Time Frame: 6 months after second eye implantation ] [ Designated as safety issue: No ]
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.
