RESUMEN
The proximity of the iris to the instruments and currents of cataract surgery makes iatrogenic damage to the iris a common complication of cataract surgery. This article discusses techniques to prevent or minimize this damage. When damage does occur, the surgeon must decide if, when, and how to repair the damage. Principles governing these decisions and techniques for repair are discussed. Figures and videos, included as online Supplemental Data files, illustrate cases of iatrogenic damage and repair techniques.

Posterior polar cataracts present a unique challenge for the cataract surgeon. This review describes the steps a surgeon can take to overcome these challenges for the successful phacoemulsification of the posterior polar cataract. Proper preoperative examination and diagnostics will allow appropriate preoperative counseling and surgical planning to increase the likelihood of success. Specific techniques for each stage of the procedure are described, all with the aim of protecting the posterior capsule and preserving intraocular lens (IOL) fixation options. Posterior polar cataracts present dilemmas in preoperative evaluation, surgical management, and IOL fixation.
