Research Progress on the Pathogenesis and Preventive Methods of Presbyopia
Presbyopia is an age-related condition characterized by decreased elasticity and plasticity of the crystalline lens,weakened ciliary muscle function,leading to difficulties in near work and reading,short-lasting focus on objects,and increased susceptibility to visual fatigue.This article provides a comprehensive review of the pathogenesis and treatment methods of presby-opia.The Factors influencing presbyopia include age,gender,diseases,and medications.Treat-ment methods mainly include optical correction,surgery,and drug therapy,all of which can im-prove near vision difficulties to some extent.Currently,optical correction is the most common treat-ment method.Corrective surgeries include corneal,crystalline lens,and scleral surgeries,each with certain limitations and risks.Medicine therapies involve miotic medicines,agents to restore crystalline lens elasticity,and Traditional Chinese Medicine,but many are still in the research stage.This study,by summarizing the pathogenesis and treatment methods of presbyopia,provides insights for future clinical research and interventions.
