Abstract:
Objective To establish a standardized supply model for ophthalmic surgical instruments using lean manage-ment methods,develop a formula for determining optimal instrument inventory levels,and improve the management efficiency of ophthalmic surgical instruments.Methods A total of 2,281 cataract instrument sets from January 2023 to December 2024 were analyzed.From January to December 2023(1 141 sets),conventional process management was implemented,while from January to December 2024(1 140 sets),a lean theory-based standardized model was applied.Key parameters including surgical time,sterilization workflow,and instrument management were recorded to establish the model.A quantitative analysis incorporating sur-gical time,turnover interval,transportation time,relaxation rate,cycle interval,and target instruments was conducted to derive the inventory formula.A two-month pilot study on cataract surgeries was performed to validate the model's feasibility.The inci-dence of special events before and after implementing the standardized model was compared.Results The formula-derived data aligned with clinical demands,demonstrating precise quantification of ophthalmic instrument sets and high process stability.The incidence of special events post-implementation was significantly lower than pre-implementation(P＜0.05).Conclusion The lean theory-based standardized supply model effectively enhances the management of ophthalmic surgical instruments.
