Can a Catholic married to an Orthodox in an Orthodox church re-celebrate her wedding in a Catholic church? My Catholic daughter will marry an Orthodox boy in an Orthodox church in Macedonia. After this ceremony we will go to Slovakia to continue the celebration. Can we celebrate a Mass in a Catholic church (not a wedding) and repeat the promise to God to validate the wedding?
According to the Catholic Church, your daughter's marriage to a non-Catholic, without her bishop's permission, is invalid; so she would absolutely need to marry in the Catholic Church.

From the section "Mixed Marriages" of the Code of Canon Law:


  Can.  1124 Without express permission of the competent authority, a marriage is prohibited between two baptized persons of whom one is baptized in the Catholic Church or received into it after baptism and has not defected from it by a formal act and the other of whom is enrolled in a Church or ecclesial community not in full communion with the Catholic Church.


The Catholic Church considers any Eastern Orthodox "not in full communion with the Catholic Church;" they are schismatics.

Your daughter can get permission to marry a non-Catholic from her Catholic bishop. Your daughter would have to


  [Can. 1125 §1] …declare that…she is prepared to remove dangers of defecting from the faith and is to make a sincere promise to do all in his or her power so that all offspring are baptized and brought up in the Catholic Church. 


And her fiancé


  [§2] …is to be informed at an appropriate time about the promises which the Catholic party [your daughter] is to make, in such a way that it is certain that he…is truly aware of the promise and obligation of the Catholic party [your daughter].


Both your daughter and her fiancé


  [§3] …are to be instructed about the purposes and essential properties of marriage which neither of the contracting parties is to exclude.
