One of the major decisions prior to Cataract Surgery is the type of lens to be used. Considering that Cataract surgery and lens replacement is permanent, it necessitates that you choose your lens options very carefully before going ahead with the surgery.
Advancement in ophthalmic surgery techniques and the technology used to design intraocular lenses (IOLs) i.e. the artificial lenses that are implanted during cataract eye surgery have become very powerful and can dramatically improve vision.
There are several different types of cataract lenses available, and the decision about which ones to go for should be based on what’s most important to you Go on and read below to get an insight into the various options and consult Dr Nita Shah to get all your queries answered
Standard lens (Monofocal)
A monofocal lens will let you see very clearly, but only at one distance. So if you choose to have a lens to improve your vision to help with short-sightedness, you may still need to wear glasses to see clearly at a distance, and vice versa.
There are three different distances, and the one that you want to improve will depend on what you do on a daily basis.
• Long distance – if you drive for a living, then improving your long distance vision could help immensely. This could also be a good choice if you like to watch a lot of television, or if you are a keen golf player.
• Middle distance – this type of distance is similar to the distance that you would view a computer screen from. If you work in an office job, and have to spend a large portion of your day looking at a screen, you may well benefit from improving your middle distance vision.
• Short distance – if you like to read a lot, then improving your short distance vision could be a good option for you. This may be beneficial if you spend a lot of time reading paper documents for work.
If you have astigmatism, a Toric lens will improve your vision at one specific distance. You may find that astigmatism blurs your vision slightly, so choosing to have this issue fixed with a Toric lens could be beneficial to you.
A multifocal lens replacement will help improve your vision at a number of different distances, and could be helpful if you are constantly switching distances during the day.
For example, if you need to switch from making notes on paper in front of you, to looking at your screen, then on to looking at a presentation at the front of the room, you will want to be able to do so without having to change your glasses each time.
If you don’t like the thought of using a multifocal lens, you could opt for monovision. This is where a single vision lens for one distance is implanted into one eye, and a lens for a different distance is implanted into another, correcting problems with long-sightedness and short-sightedness. This means that you should be able to see both far and near, without having to get used to the differing focus of a multifocal lens.
Prior to your consultation, make a note of the activities you do every day and discuss with your doctor to help take an informed decision regarding the most suitable lens for you. Whichever lens you choose, cataract eye surgery combined with lens replacement can be life changing. The operation is quick and painless. And the results are almost immediate.
