As we all get older, our vision changes. In our 40s and 50s the muscles of the eye weaken and the lens becomes denser and more resistant to changing shape. The result is that our eyes lose their ability to easily see up close as well as we did when we were younger. This process is known as presbyopia and it is very annoying. This is the reason that people need reading glasses. This process will occur earlier for longsighted people. The good news is that Dr LaHood offers permanent solutions with both surgery and laser so that you never will need reading glasses again. Read below for options.
Using laser vision correction techniques, the focus of each eye can be made to whatever we want. One option is to make one eye good for distance vision and the other good for near vision. This is called monovision or blended vision. The brain gets used to this very rapidly and you do not even realise you are only using one eye at a time. If your eyes are healthy with minimal cataract this can be an excellent option and for many people means only having laser treatment to one eye. This is a fast and effective way to fix presbyopia. If we are concerned about whether your brain will tolerate this monovision option, a contact lens trial can be organised with your optometrist prior to laser treatment. Possibly you may just like the contact lens option and stick with that.
Lens surgery monovision
Similar to above, one eye is made better for distance and the other better for near vision. The difference is that instead of changing the shape of the cornea, Dr LaHood will remove your lens as with cataract surgery and replace it with a personalised IOL to suit your needs. The benefit of this is that the surgery is permanent so you will not need to go on and have cataract surgery when you get older. Again, a contact lens trial can be helpful to determine if you like this option although sometimes in the presence of cataract it can be tricky to tell due to the cataract impairing the quality of your vision. This is something that you can discuss with Dr LaHood.
The trifocal IOL gives three focal points and is a favourite of mine. If you want everything for your vision, this may be the best option for you. It gives good distance, intermediate and near vision meaning that you should not need glasses for any task including reading. The trade off is that you will initially experience glare and halos especially at night that will reduce over the first month. Maximum benefit is gained with this IOL in both eyes but one eye can be implanted as a mixture.
Newer IOL types and combinations
Dr LaHood is at the forefront of IOL technology and has access and experience with a wide variety of IOLs. As technology changes, new options become available and you will be offered the best options available. Not all lenses suit all eyes and so sometimes a combination of approaches is necessary. This will be discussed in detail before your surgery.
