Custom Vision Design
What is Refractive Design?
Our eyes may look pretty similar on the outside, but the view from the inside varies widely between individuals.
Each of us has a unique set of eyes that we lived with for decades before developing cataracts. This is our 'optical world'. Some of us are nearsighted. Some see best at distance. Some of us are completely dependent on glasses or contact lenses; others don't spent a moment thinking about them.
Each of us has also different interests. Some people like to ski and hike and rarely sit down. Others find fulfillment in crafts and detailed close up work.
Cataract surgery is a unique opportunity for you to customize your vision for the life you lead. You can move beyond what you were born with, and create the vision that suits you.
Key Principles of Refractive Design with Micro Monovision
Refractive Design with Micro Monovision allows you to create eyes that are customized for activities that are important to you. There are three key principles:
1. The depth of focus that you experience can be increased by focusing the eyes at slightly different distances (Micro Monovision).
2. Micro monovision expands depth of focus, but does not provide the full depth of focus required to simultaneously read and see at distance.
3. Because of #2, it is necessary to choose the Refractive Path (distance, middle, or near) that emphasizes the activities that are most important to you. Glasses will need to be worn at some times for tasks that are outside of the distance you prioritize. Mini or or full monovision can also be considered. These options are discussed in greater detail here.
Before choosing a monovision strategy, read up on presbyopia correcting intraocular lenses, so you understand the advantages and disadvantages of each option.
Talking to your surgeon
Not every surgeon will offer custom options like this unless you ask, but most will provide this level of customization if you request it.
Monovision strategies are for patients who are not electing presbyopia correction with specialty intraocular lenses. Compare the advantages and disadvantages of both strategies before deciding what you want.
