Posterior capsule opacification(PCO)is a common postoperative complication of cataract surgery, primarily caused by the proliferation and migration of residual lens epithelial cells(LECs). Although neodymium-doped yttrium aluminum garnet(Nd:YAG)laser posterior capsulotomy effectively treats PCO, it carries risks of complications such as cystoid macular edema(CME). Thus, preventing PCO formation is of critical clinical importance. Despite advancements in intraocular lens(IOL)materials and designs, achieving complete PCO eradication remains challenging. This review systematically examines recent advancements in surface-modified IOLs, including anti-biofouling IOL(reducing LECs adhesion), capsular adhesion-enhanced IOL(promoting capsular bag integration), micro-patterned IOL(physically inhibiting migration), photothermal/photodynamic IOL(inducing light-activated LECs apoptosis), and drug-eluting IOL(sustained drug release). These surface modification strategies demonstrate synergistic effects through complementary mechanisms(including physical barrier formation, chemical intervention, and bioactive regulation), effectively suppressing LECs proliferation while significantly reducing PCO incidence. Importantly, these approaches eliminate the risks associated with conventional Nd:YAG laser treatment, offering substantial advantages. By providing a comprehensive evaluation of these cutting-edge technologies, this review serves as a valuable reference for IOL design optimization. It represents a paradigm shift in cataract management strategies, transitioning from reactive therapeutic interventions to proactive preventive measures, and ultimately leads to improving long-term visual outcomes for patients.

Telemedicine can optimize deployment of medical resources and minimize diagnosis discrepancies.Formulation of a rational project pricing and scientific compensation policy will be conducive to its future development. The concept of human resource consumption in RBRVS was used as reference to improve the activity-based costing ( ABC ) method. The authors sorted out the resource cost repository, identified the activity system, classified the motivation resources into respective activity cost repositories, and calculated the cost of respective cost object distribution.The cost of three telemedicine service items(remote single discipline consultation, remote image consultation and remote pathology consultation were 119.69, 147.03 and 161.61 yuan respectively) was calculated by the improved ABC.It can better indicate project costs than that calculated by the traditional ABC(137.30, 147.17 and 144.08 yuan), and proves more consistent with the existing prices of other province(134.00, 150.00 and 174.00 yuan).
