To evaluate the target refraction of patients with binocular myopia and monocular cataract after intraocular lens (IOL) implantation.

This study comprised 199 patients with binocular myopia (axial length >25 mm) and monocular cataract after IOL implantation for the removal of the monocular cataract. The research was conducted using a questionnaire method and by performing statistical analysis of the refractive outcomes.

The patients are grouped into 3 domains (≤-3 D group, -3~-6 D group, >-6 D group). There were no statistically significant differences among the 3 groups; whereas the satisfaction of the present corrected state was statistically low in the >-6 D group ( p < 0.05). The satisfaction of the corrected state was statistically high in the group of postoperative anisometropia under 3 D ( p < 0.05). There was no statistical difference between the groups on the satisfaction of target diopter (-2~-3 D or emmetropia). In terms of correction method, glasses were worn in 119 patients (60%), contact lenses were worn in 26 patients (13%), and monovision was used in 14 patients (7%) were used respectively. Forty patients (20%) with implanted IOL in both eyes did not use any of the correction methods above. Except for the contact lens group, the general satisfaction and the satisfaction of the present corrected state were statistically lower than the other group ( p < 0.05). There was no statistically significant difference among the 3 groups in the percentage of cataract surgery in the fellow eye.

There was no statistical difference between the groups in satisfaction of target diopter (-2~-3 D or emmetropia). Setting the target refraction difference between both eyes less than 3 D leads to more satisfactory outcomes.
