Visual Outcomes and Patient Satisfactory After PanOptix Implantation in Hyperopic Cataract Patients
- Conditions
- HyperopiaCataract
- Registration Number
- NCT05716269
- Lead Sponsor
- Peking University Third Hospital
- 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.

- Pupil abnormality (non-reactive pupil, tonic pupils, abnormally shaped pupils, etc.)
- History of any clinically significant retinal pathology or ocular diagnosis (e.g. diabetic retinopathy, ischemic diseases, macular degeneration, retinal detachment, optic neuropathy optic nerve atrophy, amblyopia, strabismus, microphthalmos, aniridia, epiretinal membrane etc.) in the study eyes that could alter or limit final postoperative visual prognosis
