Cataract Lens Implants FAQ
How do lens implants help cataracts?
Cataracts occur when the lens, which lies behind the iris starts to cloud overdue to changes in its protein structure. This impairs your vision and can ultimately lead to preventable blindness. If you're considering cataract surgery, you know it's an important decision. Once you've decided to have the surgery, however, there's another important choice to make: which type of intraocular lens (IOL) to have implanted.
Would you like to enjoy freedom from glasses after surgery, or are you fine with wearing glasses? Do you have astigmatism? Is cost an issue? These are the sorts of questions you'll need to consider as you begin thinking about IOL options.
What is Astigmatism?
In a healthy human eye, the cornea is round in shape like a basketball. In astigmatism, the cornea’s shape is more like a football. When light passes through a cornea with astigmatism, the image does not focus sharply on the retina, causing blurred vision.
Cataract patients who also have astigmatism used to only have the option of wearing either glasses or contacts post surgery to completely correct their vision. Many lens implants available today actually correct for astigmatism as well as replace the lens clouded by cataracts.
What is Presbyopia?
In an eye with presbyopia, the natural lens has increasing difficulty focusing on intermediate and close objects. Common symptoms include: Losing your ability to read up-close and difficulty viewing a computer screen, phone, or tablet. You may naturally hold objects farther away to read and need reading glasses to see clearly.
