Three Common Misconceptions About Cataracts and Surgery
- Cataracts are formed on the front of the eye. This is false. Most people think the lens is on the front side of the eye, visible while looking at someone. This is not the case. In fact, the lens that forms the cataract is actually behind the visible part of a person’s eye as you can see in the diagram below.
- The lens that forms the cataract isn’t replaced. False. During cataract surgery, the surgeon will remove the cataract (the natural lens) and replace it with a new lens implant. The type of lens used will be decided on between the doctor and the patient prior to surgery, depending on the patient’s expected outcomes.
- Cataracts can return. This is also false. Once a lens is implanted, cataracts cannot return. Some patients can develop scar tissue from surgery that causes their vision to deteriorate. If you have had cataract surgery and notice a decrease in your vision, please reach out to your surgeon or eye doctor as the scar tissue can be surgically removed.
