Premium Monovision Versus Other Types of Monovision and Bilateral Trifocal Implantation.

Premium Monovision Versus Bilateral Myopic Monovision, Hybrid Monovision and Bilateral Trifocal Implantation. A Comparative Study.

Primary objective of this study was to compare the efficacy of premium monovision with Restor and Panoptix, against other prevalent monovision techniques and against bilateral Panoptix implantation in a sample of patients following lens-extraction surgery.

Four study groups were formed according to the procedure and the intraocular lens technology that was used: a) Monovision Group (MoG), b) Multifocal Lens Group (MfG), c) Hybrid Monovision Group (HmG), and, d) Premium Monovision Group (PmG). Patients who have undergone one of the above categories of presbyopia correction surgery were selected to compare the effectiveness of these techniques by evaluating the uncorrected near, intermediate and distant visual acuity as well as the degree of subjective patient satisfaction, contrast sensitivity, dysphotopsia symptoms and spectacle independence .
