Trial Outcomes & Findings for Retrospective / Prospective Clinical Study of AcrySof® IQ ReSTOR® +2.5 D Multifocal Toric Intraocular Lenses (NCT NCT02176343)

NCT ID: NCT02176343

Last Updated: 2018-07-02

Results Overview

Manifest refraction cylinder was measured monocularly (each eye separately) with best correction (phoropter or trial lenses) under photopic (well-lit) lighting conditions using a 100% contrast ETDRS chart at 4 meters (m) from the subject. Percent reduction in cylinder was calculated as the difference between the postoperative magnitude of manifest refractive cylinder and the preoperative magnitude of keratometric cylinder divided by the intended reduction in cylinder \[defined as the difference between the intended (from toric calculator) magnitude of the postoperative manifest refractive cylinder and the preoperative keratometric cylinder\], multiplied by 100%. One eye (primary eye) contributed to the analysis.

Participant Flow

Subjects were recruited from 4 study centers located in Australia.

Of the 37 enrolled, 6 subjects were exited as screen failures and were ineligible to participate in the study. This reporting group includes all subjects who provided informed consent and were determined to be eligible based upon the inclusion and exclusion criteria (As Treated) (31).

Timeframe: Preoperative and Postoperative Visit (3 to 14 months after IOL implantation)

Population: As Treated

Visual Acuity (VA) was tested monocularly without visual correction under photopic (well-lit) conditions using a 100% contrast ETDRS chart positioned 4 m from the subject. A +0.25 D spherical power additional lens was used to correct for optical infinity. VA was measured in logMAR (logarithm of the minimum angle of resolution), with 0.1 logMAR increment corresponding to 5 letters, or 1 line, on an ETDRS chart. A lower numeric value represents better visual acuity. One eye (primary eye) contributed to the analysis.

VA was tested monocularly without visual correction under photopic lighting conditions using a 100% contrast near ETDRS chart set at 40 cm on the nearpoint rod of the phoropter. VA was measured in logMAR, with 0.1 logMAR increment corresponding to 5 letters, or 1 line, on an ETDRS chart. A lower numeric value represents better visual acuity.

Lens axis orientation (position of the lens within the capsular bag) as indicated by indentations on the IOL was assessed during slit lamp examination. IOL rotation (the difference between the achieved lens axis orientation at visit and achieved axis placement at surgery) was measured in degrees. One eye (primary eye) contributed to the analysis.
