Abstract: The purpose of this work was to obtain an optimised long-term aciclovir PLGA microspheres formulation for intravitreal administration to minimise, as much as possible, the dose of microspheres to be administered with a suitable particle size for its injection through a 27G needle in a single dose. Microspheres were prepared by the solvent evaporation method. To obtain the optimum formulation a two-factor five-level central rotatable composite 2(2) + star design was employed. The independent variables were acic…
