How do I know what IOL to choose?
Your doctor will guide you through this process depending on your individual needs and preferences.
IOL Measurements
The Wellington Eye Clinic uses the gold standard for determining IOL power, namely the IOL Master from Zeiss. It has greatly increased the accuracy of the IOL to give the intended visual outcome. It is a non-touch test that takes just a few minutes. We have a 2nd device called the Biograph that appears to be even more accurate and versatile than the IOL Master so between the 2 measuring devices, we will have the most accurate IOL power calculation currently available anywhere in Ireland. For very dense cataracts where neither of these devices can work, we have an A-Scan for biometry to determine IOL power.
How do I know what refraction to target?
If you would like good distance vision after the operation without the use of glasses, then you will require both eyes targeted for distance. If you choose this option, you will require reading glasses for all near vision tasks. You may still require a light pair of distance glasses to improve the distance vision as best possible for driving and television. Without your glasses on though, your best vision is going to be in the distance.
If you would like to be without glasses completely or for as much of the time as possible, then you may wish to target MONOVISION. Here one eye is treated for distance vision and the other for near vision. Glasses are only required on occasion when monovision works well. Most monovision patients do not wear glasses at all but some would for night driving and prolonged reading.
Premium IOL's
There are IOL’s that can improve the uncorrected vision even more without the use of glasses. These include multifocal IOL’s, toric IOL’s that correct astigmatism and aspheric IOL’s that specifically improve night vision and depth of field. There is a section dedicated to premium IOL’s and your doctor will discuss this in detail with you if it interests you. Premium IOL’s do cost more but they provide less spectacle dependence after the cataract operation. They also include the costs for any corneal laser surgery that you may need afterwards to further improve the results.
