Trial Outcomes & Findings for A Comparison of Visual Function After Bilateral Implantation of Presbyopia-Correcting Intraocular Lenses (IOLs) (NCT NCT01257217)

NCT ID: NCT01257217

Last Updated: 2018-07-02

Results Overview

Defocus VA (an indicator of the expected range of vision with a presbyopia-correcting IOL) was tested binocularly with the participant's best spectacle correction using a chart. Lenses of different spherical powers were placed in front of the eyes to produce varying levels of defocus. The VA at each spherical power was measured in logarithm of the minimum angle of resolution (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.

Participant Flow

Subjects were recruited from one investigative site located in Spain.

Of the 31 enrolled participants, 1 exited prior to randomization due to withdrawn consent and 5 discontinued after randomization due to adverse event (1) and protocol deviation (4). This reporting group includes all randomized participants who received IOLs without major deviations and/or surgical complications (efficacy population).

SECONDARY outcome

Timeframe: Month 3 from second eye implantation

Population: This analysis population includes all subjects who received IOLs without major deviations and/or surgical complications.

Visual acuity (VA) was tested binocularly (both eyes together) with correction in place if needed across a range of distances under well-lit conditions using Early Treatment of Diabetic Retinopathy Study (ETDRS) charts. VA was measured in logarithm of the minimum angle of resolution (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.

Population: This analysis population includes all subjects who received IOLs without major deviations and/or surgical complications.

A manifest refraction (vision check) was performed using a 100% contrast ETDRS chart under well-lit conditions. Results were documented for sphere, cylinder and axis readings. The refractive spherical equivalent was calculated according to the formula: sphere + ½ cylinder power. Both eyes contributed to the mean.

SECONDARY outcome

Timeframe: Month 3 from second eye implantation

Population: This analysis population includes all subjects who received IOLs without major deviations and/or surgical complications.

The Visual Task Difficulty Assessment (VISTAS) questionnaire was completed by the subject to assess difficulty in completing everyday tasks that depend on good vision. Tasks were rated using a 1 to 5 point scale, where 1 = no difficulty; 2 = minor difficulty; 3 = moderate difficulty; 4 = major difficulty; 5 = cannot accomplish. Individual scores for each task were averaged to obtain the overall score for each vision type/function. Near vision was defined as less than 50 cm; intermediate vision as 50 cm to 1 m; extended intermediate vision as 90 cm to 4 m; and distant vision as more than 4 m.
