简要总结
The aim of this study is to observe the influence of pupil size upon visual outcome in patients with Visian Implantable Collamer Lens(ICL) and toric-ICL implantation.
详细描述
The aim of this study is to observe the influence of pupil size upon the quality of vision outcome in patients with Visian Implantable Collamer Lens(ICL) and toric-ICL implantation. Pre-operation and 3-month post-operation pupil size, visual acuity, quality of vision will be evaluated in patient that had ICL surgery.
