Night vision after cataract surgery is a common concern. Unwanted images can occur with all implants. These can take the form of glare or starburst. One should expect halos with multifocal implants. Not infrequently, patients observe a shadow in the outer field of their vision after cataract surgery which typically fades over time.  Your tolerance to halos will influence your decision about multifocal lenses and will be discussed at your preoperative consultation.
