摘 要：Inflammatory events in the corneal stroma may activate keratocytes and trigger their transition towards myofibroblasts,which now produce different extracellular matrix(ECM)proteins thus causing corneal *** haze is a frequent side effect after photorefractive keratectomy(PRK)to correct high ***,a preventive treatment with mitomycin-c can be used to limit the occurrence of this ***,mitomycin-c is a toxic drug,not devoid of side effects,which may occasionally involve the corneal ***,we have searched for a less risky,natural way,to prevent keratocytes *** this purpose,we have used as markers of the phenotype switch the proteins lumican(highly expressed by keratocytes and much less by myofibroblasts)and smooth muscle actin(αSMA)(highly expressed by myofibroblasts and poorly found in keratocytes),beside Fibronectin(Fn),the expression of which is also increased by transforming growth factor-beta(TGFβ)*** of human keratocytes with TGFβwas used to induce the protein *** different possible candidates,we have found that vitamins A and E,hyaluronic and lactobionic acids may prevent,either alone,or much better in association,the shift in the ratio between lumican andαSMA and the increased Fn *** conclusion,it could be speculated that topic treatment of the ocular surface with an association of these four compounds could be able to prevent or at least limit the occurrence of post-PRK corneal haze,with the additional advantage of lubrication,hydration and antioxidant defense exerted by these molecules.
