- Primary Outcome Measures
Name Time Method Comparison between visual performances under bright (photopic) and dim (mesopic) conditions in patients who had undergone uncomplicated cataract extraction with different types of monofocal intraocular lens (IOL) implantation using contrast sensitivity measurement.Timepoint: 12 Months
- Secondary Outcome Measures
Name Time Method At 3 weeks after surgery, the monocular contrast sensitivity function was measured using Pelli Robson Contrast Sensitivity measurement chart at one photopic luminance level and one mesopic luminance levels.Timepoint: At 3 weeks after surgery, the monocular contrast sensitivity function was measured using Pelli Robson Contrast Sensitivity measurement chart at one photopic luminance level and one mesopic luminance levels.
