Why is choosing a lens like choosing a car?
A family carrying children, groceries and a dog may value space and practicality. Someone who enjoys a weekend drive may prefer a sports car. A person making short trips around town may want a small car that is easy to park.
These are all reasonable choices. The sports car is not automatically better because it is faster or more expensive. It might be the wrong car for the family.
Lens implants also offer different combinations of features. A lens that suits one person very well may be a poor match for someone else. More features do not necessarily mean a better fit.
What does your everyday life require?
Think about the vision you use most: driving, reading, computer work, gardening, sewing or playing sport. Even two people who both enjoy reading may hold a book at different distances or read different-sized print.
How much do you want to reduce your reliance on glasses? Would wearing reading glasses be a small inconvenience, or a major frustration? How important is driving at night?
There is no right answer for everyone. Your priorities help identify which lens implant options are worth considering.
Which compromises are acceptable to you?
A spacious car may be harder to park; a compact car may have less room for luggage. Lens choices also involve trade-offs.
A monofocal lens can provide excellent vision at its planned focus, usually with glasses needed for other distances. Extended depth of focus (EDOF) lenses can offer more intermediate vision, while multifocal lenses can provide a wider range including near vision. Depending on the design, these benefits can involve compromises such as haloes, glare or reduced contrast. No lens guarantees freedom from glasses.
The fuller guide to EDOF and multifocal lens trade-offs explains these choices. A monofocal lens is a valid positive choice, rather than a second-best option.
Why do your eyes matter as well?
Your preferences are only part of the decision. The shape and health of your cornea, astigmatism, retinal health, glaucoma and previous eye surgery can influence suitability. Measurements also determine the lens power and planned focus.
Even eye doctors choosing lenses for themselves have different priorities and different eyes.
A more useful question is: “Which lens best suits my eyes and the way I live?” Tell your surgeon what you want to do comfortably, what you value most and which compromises you would find difficult.
