Monovision Correction Preference and Eye Dominance Measurements.

Area of Science:

• Ophthalmology
• Optometry
• Vision Science

Background:

• Presbyopia management often involves monovision correction, requiring careful eye selection for optimal visual outcomes.
• Accurate identification of the dominant eye is crucial for successful monovision fitting.
• Existing methods for eye dominance determination may not fully capture perceptual preferences relevant to monovision.

Purpose of the Study:

• To introduce and evaluate novel psychophysical methods for selecting the non-dominant eye in presbyopic monovision correction.
• To compare the efficacy of new perceptual tests against standard sensory and sighting dominance tests.

Main Methods:

• Twenty subjects with presbyopia underwent standard sensory and sighting eye dominance tests.
• Two psychophysical tests, the Preferential test and the Multifocal Acceptance Score (MAS-2EV) test, were employed to assess perceived visual quality and eye dominance strength (EDS).
• A Simultaneous Vision Simulator facilitated rapid comparison of different monovision corrections.

Main Results:

• Standard sensory and sighting dominance matched in only 55% of subjects.
• The Preferential test EDS and MAS-2EV EDS showed a high correlation.
• Using the Preferential test as the gold standard, the MAS-2EV, sensory, and sighting tests achieved 79%, 64%, and 43% success rates, respectively, in selecting the correct eye for distance vision.

Conclusions:

• Perceptual preference-based tests effectively identify the preferred eye for monovision correction and quantify eye dominance strength.
• These new methods offer improved accuracy for eye selection in presbyopic monovision compared to traditional approaches.
• The binocular visual simulator enables efficient clinical application of these eye preference tests.
