Phacoemulsification with viscodissection in posterior polar cataract: minimizing risk of posterior capsule tear.

We retrospectively evaluated the efficacy of viscodissection in decreasing the risk of posterior capsule tear during phacoemulsification surgery in 23 eyes with posterior polar cataract. Eyes were randomly assigned to two groups prior to emulsification: cortical viscodissection (Group 1) or non-viscodissection (Group 2). The visual acuities similarly improved in all eyes in the two groups. Posterior capsule tear occurred in one eye in Group 1 and five eyes in Group 2 (p < 0.05). On the basis of these results, the viscodissection technique was safer and more efficient than the non-dissection technique.
