Because of the application of vitreoretinal surgical techniques to a broader range of posterior segment diseases and because cataract develops frequently in postvitrectomy eyes, cataract surgeons should be familiar with the challenges of cataract extraction in vitrectomized eyes. The cataract surgeon can prepare for these challenges with awareness of such potential factors as an excessively mobile posterior capsule, possible need for vitrectomy equipment, and special considerations concerning intraocular lens selection and power calculation. Knowledge of ocular comorbidities will help the cataract surgeon to counsel the patient appropriately and will help the patient to form realistic expectations. Despite the challenges it presents, cataract extraction in postvitrectomy eyes is usually associated with favorable visual outcomes.
