Artificial Lenses including Multifocals
Cataract surgery is a very common operation as cataract occurs to all of us as we get older. The success of the operation itself is largely dependant on the artificial lens that is implanted in one’s eye.
At Hunter Cataract & Eye Centre, we go to great lengths to try and determine the exact strength of lens that is required for your eye by using only the latest equipment and the most recently validated methods.
Artificial Lens Types
When it comes to the artificial lens itself, there are 3 broad types of lenses available:
- Single vision lenses (monofocal)
- Depth of focus lenses
- Multifocal lenses
The choice of lens is very dependent on each person’s individual circumstances as well as their desire for spectacle independence.
Monofocal, Depth of focus, and Multifocal lenses
Broadly, monofocal lenses have a single focus point which can be set for either distance, near or a combination of both. It is very likely that spectacles will still be needed for either reading or distance tasks after surgery.
Depth of focus lenses enable a greater range of vision giving clear distance vision as well as intermediate, computer distance vision, and a moderate amount of near vision. It is not unusual, however, to still require reading glasses in low-light conditions
Multifocal lenses have multiple focal points, including distance, intermediate and near and have the highest chance of spectacle independence at around 90%. However, it must be noted that people with multifocal lenses will be aware of rings and haloes around lights at night. The vast majority of people will adapt to this over time, and the light phenomenon should not be intrusive or prevent one from doing any nighttime tasks.
