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.

When it comes to the artificial lens itself, there are 3 broad types of lenses available:

1. Single vision lenses (monofocal)

2. Depth of focus lenses

3. Multifocal lenses

The choice of lens is very dependent on each person's individual circumstances as well as their desire for spectacle independence.

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 the 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 diastance vision as well as intermediate, computer distance vision, although reading glasses are not unusual for low light conditions.

Multifocal lenses have multiple focal points including distance, intermediate and near and have the highest chance of spectacle independance at around 95%.  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 night time tasks.

All in all, one's refractive outcome does need to be discussed with your surgeon and a decision about lenses needs to be made.  We are more than willing to help you in this regard during your consultation.  We aim to achieve a high quality of vision with your outcomes meeting your expectations.
