Abstract

Purpose : The purpose of the study was to characterise the visual performance achieved by AcrySof® IQ Monofocal intra ocular lenses (IOL) taking into consideration the three factors affecting performance: luminance, contrast and time to perform the test.

Methods : Pseudophakes bilaterally implanted with AcrySof® IQ Monofocal IOL constituted the study population. Two sets of logMAR charts: OTG-i Vision Suite system and ETDRS were used as follows: i. high contrast (90%) charts under high photopic condition (250cd/m2) representing outdoor daytime, medium photopic condition (85cd/m2) depicting indoor; ii. low contrast charts (10%) at 250cd/m2; iii. Under time-controlled condition (7.5seconds to read ten letters) at 250cd/m2 with 90% and 10% contrast charts.

Results : 21 ((11F, 10M) participants, mean age of 71 ± 8 years (range 51 to 83), close to emmetropia, mean spherical correction of +0.36 ± 0.56D and uncorrected astigmatism of -0.52 ± 0.43D, constituted the study population. The best corrected visual performance was as follows: i. 90% contrast daytime outdoor visual performance was excellent (-0.072 logMAR (20/16.9) and remained superior to 20/20, for indoor condition under lower light level: OTG-i (-0.041 logMAR (20/18.2) ETDRS (-0.046 logMAR (20/18.0); ii. 10% contrast daytime outdoor visual performance was also excellent and close to 20/20 (-0.072 logMAR (20/16.9); iii. the performance recorded at high luminance was maintained under time limited testing condition 90% (-0.071 logMAR (20/17.0) and 10% (0.058 logMAR (20/22.9).

Conclusions : Measurements under environmental conditions representative of the full range of daily conditions, showed that AcrySof® IQ Monofocal IOL excellent visual performance recorded by standard testing was maintained under reduced luminance, contrast and time to perform the test, demonstrating its functionality under the range of visual environmental conditions encountered in everyday life.
