The etiology of PCO is incompletely known. The surgical trauma might activate LECs in a wound-healing process. Several experimental studies showed that some agents have been effective in inhibiting LECs proliferation and differentiation, and also in development of PCO, such as anti-metabolites, nonsteroid antiphlogistic drugs, cyclosporin A.

大量的体外实验已经证实抗代谢药物如5-氟脲嘧啶、丝裂霉素、柔红霉素等，环孢霉素A等皆可抑制晶状体上皮细胞的增殖和分化，但这些药物对眼内其他正常组织的毒副作用限制了其临床应用。

Retinal laser photocoagulation is necessary for the peripheral lattice retinal degeneration associated with hole, vitreous traction, local detachment, aphakic eye or pseudoplatic eye to prevent retinal detachment, and it is effective and safe.

The simulation results are valuable for temperature control and anti-cracking design of high arch dam.

仿真结果对混凝土高拱坝的温控防裂设计有参考价值。

Study shows that compaction and cementation can play a destructive role in Suining formation reservoir,while dissolution and fracturing can play a constructive role in that.The main facies of Suining formation are ferruginous-shale film,anhydrite,dolomite and calcite.The micro-fracture and grain-edged fracture mainly resulted from compaction fracturing,compaction slipping and tectonic dynamic force greatly improve the reservoir permeability.

研究表明：①对遂宁组储层起破坏作用的是压实作用、胶结作用和交代作用，而溶蚀作用、压裂作用则对储层起到建设性作用；②遂宁组最主要的成岩相组合为铁泥膜－硬石膏－白云石－方解石成岩相；③由压实破裂、压实滑动和构造动力形成的微裂缝、粒缘缝有效改善了储层的渗透性。
