We are presenting modified orbital elements of the two close visual binary systemsHip111314 and Hip68170. The orbits were solved using the observational measurements in the Fourth Catalog of Interferometric Measurements of Binary Stars, and the old orbital elements published in the Sixth Catalog of Orbits of Visual Binary Stars. . The Least Squares Method for the two-body problem and Kepler?s laws were used to solve the orbits. It has been employed by Tokovinin through a computer program named Orbitx under IDL platform. The results coincide with the old solutions, but with higher accuracy and less error values
