Objectives
Narrative objectives1
To improve near and intermediate vision, we recently began to adjust the postoperative refraction of some myopic patients to near distance in the dominant eyes and intermediate distance in nondominant eyes.Because this method utilizes the basic principle of monovision, we termed this method as a myopic pseuodophakic monovision. The purpose of this study is to examine the binocular visual function of patients with myopic monovision.

Assessment
Primary outcomes
1.Binocular uncorrected and distance-corrected visual acuity (VA) at various distances was measured using the all-distance vision tester (KOWA AS=15), and 2.contrast visual acuity (CAT-2000) and 3.near stereoacuity (Titmus stereo test) were examined.
Key secondary outcomes
4.Refraction, corneal astigmatism
5.Pupil diameter
6.Patient questionnaire...patient satisfaction, spectacle independency

Interventions/Control_1
Sixty myopic patients were randomized to one of two groups: patients whose refraction was targeted to -2.75D in dominant eye and -1.75D in nondominant eye (myopic monovision), and patients whose refraction were targeted to -2.75D bilaterally (non-monovision).
Interventions/Control_2
patients whose refraction were targeted to -2.75D bilaterally (non-monovision).

Key inclusion criteria
We began screening all consecutive highly or moderately myopic patients scheduled for bilateral cataract surgery at the Hayashi Eye Hospital who wanted to see near distance after cataract surgery. Screening was continued until 60 patients were recruited.
Key exclusion criteria
Exclusion criteria were eyes with any pathology of the optic nerve, macula, or cornea; severe opaque media other than cataract; eyes scheduled for planned extracapsular cataract extraction; a history of previous ocular surgery or inflammation; abnormal ocular position (esophoria or exophoria); pupillary diameter smaller than 4.5 mm after full pupil dilation; patient refusal; and any difficulty with examination or follow-up.
