The location of corneoscleral incisions for phacoemulsification can be chosen according to the preoperative astigmatism without inducing additional adverse effects on the corneal endothelium. Shorter eyes have a significantly higher risk for greater endothelial cell loss.

Results of defocus curves disregard the diminutions of minus glasses, the normally restricted viewing distance to 6 m for distance acuity determination, and in particular the physiological miosis caused by the near-point reaction.

For diffractive designed multifocal IOLs, emmetropia and a low astigmatism postoperatively are the most important factors for high patient satisfaction.

Asymmetric implantation of posterior chamber lenses should be strictly avoided. Multifocal lenses require special attention concerning symmetric capsulorhexis and positioning of their haptics.
