Purpose:To investigate the efficacy of progressive addition lenses on the treatment of ametropia and loss of accomodation after the single eye's IOL implantation.Methods:Eighty four patients undergoing IOL implantation in single eyes were prescribed with progressive addition lenses for ametropia correction and regularly followed up to observe subsequent correction effect.Results:Among these 84 patients,72 could comfortably adapt to the use of progressive addition lenses to improve visual acuity and accomondation,while the remaining 12 patients failed to accomodate the usage of progressive addition lenses.Conclusion:Wearing progressive addition lenses acts as a relatively feasible approach to improve visual acuity and alleviate disorders of accomodation for patients who underwent IOL implantation in single eyes.The patients should be prescribed with progressive lenses under professional instructions and guidance.
