Retinal Consideration in Cataract Surgery Dr . Mohamed ELShafie , MD Prepared and presented by Free, focused mini-lessons
Cataract surgery is safe… No complications in 95%, 91% achieving vision ≥6/12, 50% ≥6/6…
…but some patients still fail to achieve a satisfactory vision
Don’t lose sight of retinal disease when visualizing outcomes
provide a good visual outcome without exacerbating underlying retinal disease or creating any new problems with the retina . “ “

PATIENT COUNSELING Although the final visual outcome often remains in doubt for weeks or even months, encourage the patient not to give up hope unless the eye has permanent loss of vision. The emotions run from depression to exhilaration. Compassion, competence, and commitment are appreciated by the patient. Be realistic but not overly pessimistic about potential outcomes
patient selection is key
