Visual Outcomes and Patient Satisfactory After PanOptix Implantation in Hyperopic Cataract Patients

Study Overview
=================
Brief Summary
-----------------
To evaluate visual outcomes and patient satisfactory after PanOptix implantation in hyperopic cataract patients

Detailed Description
-----------------
Patients with axial length ≤22.5mm will be recruited. The subjects will undergo bilateral uneventful phacoemulsification and implantation of PanOptix. Visual quality and patients satisfactory will be assessed three months after the surgery.
