简要总结
To evaluate effectiveness and safety of the POD F GF Intraocular Lens (IOL) when implanted to replace the natural lens following cataract removal
详细描述
Since the investigational lens, like conventional IOLs, is a posterior chamber lens which is widely implanted following cataract extraction, phacoemulsification is adopted. To assess the binocular vision, the investigational lens will be bilaterally implanted. Considering the safety of the study subjects, the time of implant to the remaining eye (2nd eye) will be decided based on the results of the 1st implant.
