Clareon Intraocular Lens Stability in Vitrectomy Patients: CLOVE Study

Inclusion Criteria: * Patients with a diagnosis of senile cataracts and epiretinal membranes or vitreous hemorrhage * Age between 50 and 80 years. Exclusion Criteria: * Diagnosis of vision-impairing diseases including uveitis, glaucoma and corneal pathologies resulting in high astigmatism, severe refractive error (preoperative spherical equivalent of either eye \>-6.00D or +5.00D); * Diagnosis of possible lenses instability including History of ocular trauma, Pseudoexfoliation syndrome; past refractive surgery or other ophthalmic surgery; * Known Capsular or zonular disorders that might affect the post-operative centration of IOLs, e.g., pseudo-exfoliation syndrome or Marfan syndrome; * Surgical complications including severe hyphema, iris injury, repeated IOL implantation during surgery, failure to achieve in-the-bag IOL implantation, posterior capsular rupture, usage of tamponade (gas or oil) and corneal sutures. * Difficulty in obtaining IOL measurements (eg. Small pupil, corneal opacities, patient cooperation)
