The purposes of the present study were to compare the effects of viscoelastic materials available in phacoemulsification in dogs and to evaluated ARTZ^(r) as their substitute, Six eyes from the healthy adult dogs were used in each group with different viscoelastic materials, Healon^(r), Viscoat^(r) and Occucoal^(r) and ARTZ^(r). The phacoemulsification was carried out with surgical microscope(Leica M651, Germany) and phacoemulsification system(Nidek 6000, Japan). ARTZ^(r) had lower pseudoplasticity than other viscoelastics. There was not significant difference in phacotime, rate of posterior capsule rupture, incidence of the intraocular inflammation among the viscoelastic materials. The corneal thickness in all groups was significantly increased in a day after operation and decreased gradually. However ARTZ^(r) had more time to recover the preoperative thickness than the others. Conjunctival congestion in the group with ARTZ^(r) was more severe but there were no postoperative posterior capsule opacity and visual loss. The present study indicated that ARTZ^(r) could be used as viscoelastic material in dogs with respect to the vision after surgery.
