Presbyopia Clinical Trial
Official title:
Ocular Biomarkers for Successful Premium Trifocal Intra-ocular Lenses Implantation
The purpose of this study is to identify ocular biomarkers that can predict the success of phacoemulsification with bilateral AT LISA try 839MP (Carl Zeiss Meditec AG) implantation to achieve satisfactory post-post-operativly spectacle-free vision. Social, biometric and patient reported outcomes will be evaluated.
Pre-operatively all patients were submitted to a comprehensive ophthalmic history and examination including, corneal topography, and aberrometry (Pentacam), biometry (IOLMaster 700, Carl Zeiss Meditec AG, Jena, Germany), specular microscopy (CEM 539, Nidek Co Ltd.), and macular and papillary Optical Coherence Tomography (Cirrus 4000 Hd OCT, Carl Zeiss Meditec AG). All surgeries were performed by the same surgeon done by standard phacoemulsification with in-the-bag IOL placement. Patients had both eyes operated within a week. Patients were assessed at day 1, 6, and month 3 after surgery. Six months post-operatively, refraction and slit-lamp examination was performed, and patients asked to complete the patient reported outcome questionnaire that evaluates visual satisfaction, spectacle independence and dysphoptsia like-symptoms. ;
