Trial Outcomes & Findings for Contralateral ReSTOR / Monofocal or Phakic Eye (NCT NCT00731640)

NCT ID: NCT00731640

Last Updated: 2010-03-23

Results Overview

Uncorrected Visual Acuity (VA) is measured in logMAR. LogMAR is the "logarithm of the minimum angle of resolution". A lower logMAR value indicates better visual acuity.

Participant Flow

This is a retrospective study that required patients with unilateral implantation of the AcrySof ReSTOR Intraocular Lens (IOL). Patients were to be free of conditions or ocular co-morbidities that may affect visual acuity.

During the preoperative exam, subjects were examined to ensure they met the inclusion/exclusion criteria. Only subjects who signed an informed consent and qualified to be in the study by meeting all inclusion/exclusion criteria were enrolled. This study was not randomized.

SECONDARY outcome

Timeframe: 6 Months

Contrast sensitivity is the measurement of one's ability to detect slight changes in luminance before it becomes indistinguishable. It is measured in logarithmic (log) units by means of an illuminated box, the CSV 1000 by Vector Vision. A higher value for the logarithmic units translates to better contrast sensitivity.
