A composition for preventing or treating dry eye syndrome includes nanocomposite of a polyethylene glycol and a flavonoid as an active ingredient, and in the present invention, a catechin/PEG nanocomposite having increased catechin bioavailability is prepared by using catechins which are an antioxidant and polyethylene glycol which is a hydrophilic polymer used in a drug delivery system, and an increase in tear generation, stabilization of corneal epithelial cells, an increase in conjunctival goblet cells and enhanced anti-inflammatory effects accordance to a PEG dosage by the catechin/PEG nanocomposite are confirmed in a mouse model with dry eye syndrome.

A pharmaceutical composition for preventing or treating an ocular surface disease is disclosed, wherein the pharmaceutical composition includes, as an active component, collagen type II &#x3b1;1 based peptide SEQ ID NO: 2 isolated from chondrocyte-derived extracellular matrix (CDEM). In an alkaline burn animal mode treated with peptide SEQ ID NO: 2, the occurrence of corneal opacification is reduced as well as the expression of angiogenic factors. In addition, the expression of inflammatory markers is reduced while the expression of inflammation-inducing factor is suppressed. The peptide SEQ ID NO: 2 may be applied to a pharmaceutical composition for preventing or treating an ocular surface disease.
