The treatment choices presented to presbyopic patients will depend on many factors, including lifestyle, profession, general attitude toward vision, and levels of disposable income. The first step is ascertaining which two of the three visual acuities are most important to them: near, intermediate, or distance vision. For example, you probably wouldn't recommend a multifocal intraocular lens (IOL) to a professional airline pilot because those lenses may compromise nighttime distance vision.
When you leave a patient alone in a room, she is left to her own devices and is free to wreak havoc in your exam room if she so desires. Or look in places not meant for patients. You want your patient to be as comfortable as possible—but you want your exam room to remain intact.
A cataract is a clouding of the crystalline lens, resulting in vision loss. There are different types of cataracts, and they may be associated with underlying conditions. Understanding the differences between types of cataracts will improve clinical management of your patients.
