The objective of this study is to evaluate the clinical performance of the STAAR EVO+ Visian™ Implantable Collamer® Lens with Aspheric (EDOF) Optic as refractive elements to correct or reduce myopia or hyperopia with presbyopia with or without astigmatism.
This prospective, open-labeled, evaluation of clinical performance of the investigational EDOF and Toric EDOF (TEDOF) ICL will be conducted at a single site in the Philippines.
Up to 45-50 subjects (90 eyes) who meet all eligibility criteria will be assigned to one of the following treatment arms, as determined by their preoperative refraction and the Investigator's medical judgement:
Postoperatively, subjects will undergo ophthalmic examination at regular intervals per the study visit schedule up to 6 months after surgery.
