Conditions
Interventions
Micro monovision group:patients with both eyes implanted with Symfony IOL were divided into Micro monovision group (difference of spherical equivalent refraction of both eyes was between -0.5D and -1.
Non-micro monovision group:patients with both eyes implanted with Symfony IOL were divided into Micro monovision group (difference of spherical equivalent refraction of both eyes was <0.5D)
Mixed group:Patients implanted with Symfony IOL in the dominant eye and a bifocal IOL in the nondominant eye
