Overview of Cataract Surgery

(? Delete this page?)

Cataract surgery removes the natural lens from the inside of the eye and replaces it with an artificial lens. The procedure is brief and most patients find the experience quite tolerable.  Complications do not occur very often.

Acuity, color, glare, and contrast sensitivity are often substantially improved.   


In addition, you have a once in a lifetime opportunity to design your vision.


Think of your vision after cataract surgery as the outfit that you will wear every day, morning to night, for the rest of your life. This perspective motivates you to consider your options carefully and to know the consequences of your decisions.  This website will explain in plain English the essential concepts necessary to maximize your happiness with your vision.   To make the most of your surgery, you should understand three issues, listed below.  

1.  Do you have astigmatism?  If you do, then you could benefit from astigmatic correction.  Whether this is worth the expense depends on how much astigmatism you have and how well you want to see without glasses.  This site will explain what astigmatism is, help you figure out how much astigmatism you have, and show you how much your astigmatism affects your vision using a simulator.   

2. Do you want to correct presbyopia?  There are two ways to correct presbyopia during cataract surgery.  One is by purchasing presbyopia correcting intraocular lenses.  The other is by designing your vision using the lenses that are provided by your insurance.  This website will help you understand the advantages and disadvantages of both methods, as well as the advantages and disadvantages of choosing single focus lenses and wearing bifocals or readers. 

3.  Do you want to design your vision for a particular purpose?  Some of us are skiiers and hikers, others spend their time curled up with a book or working on crafts.  What is your passion?  When you have clear priorities, you can optimize your vision for specific tasks, and wear glasses for others.
