During the cataract examination at our practice, your vision is assessed and your visual acuity determined, and, if necessary, your contrast vision and twilight vision as well. Using biomicroscopy at the slit lamp, clouding of the eye’s lens is identified. Other possible additional causes of deteriorating vision—especially retinal and macular changes and glaucoma—must be ruled out. In discussion with you and based on previous findings, we determine how quickly the cataract is progressing, whether surgery is already necessary, and when the best time for it is.
