The prostaglandin derivative is preferably in the form of latanoprost wherein the chemical composition of latanoprost is a prostaglandin F.sub.2.alpha derivative which has the chemical name isopropyl-(Z)-7[(1R,2R,3R,5S)3,5-dihydroxy-2-[(3R)-3-hydroxy-5-phenylpentyl I]cyclo-pentyl]-5-heptenoate. The dosage of the prostaglandin derivative is generally in the range of 1.5 ug to 4.5 ug which is equivalent to 1 to 3 drops aqueous solution for human eye
