Cataract Surgery Options
There are several options available to you to achieve both distance and near vision after cataract surgery.
There are several options available to you to achieve both distance and near vision after cataract surgery. This is probably the most important decision you need to make about your cataract surgery. Please take the time to review your options and ask questions during your visit to New Eyes office. It is important for you to understand ahead of time that no guarantee can be made as to how well a patient will see after cataract surgery, and that results may differ from what was predicted or planned.
Monofocal IOL lenses have one point of focus – a single focus. They can give you either clear far or clear near vision, but not both at the same time. For example, you can choose to have monofocal IOL lenses implanted in both eyes for distance vision and wear separate reading glasses, or you can have monofocal IOL lenses implanted for near vision and wear separate glasses for your distance vision.
Monovision involves implanting an IOL in one eye that provides near vision and an IOL in the other eye that provides distance vision. Some people can adjust to this, but if you cannot, your vision may seem blurry both near and far. The depth perception may decrease due to less binocular vision because your eyes are not working together as they once did. The people who do best with this method are those who have already used monovision with contact lenses, which is a common way of correcting presbyopia. It is not suitable for everyone.
Accommodating Monofocal IOL
Accommodating IOL’s are used in situations where both good distance and good near vision are desired without the use of spectacles. These IOLs have a single focal point, however this focal point can shift position in space so that the objects at distance are clear when the eye focuses on them, but when the eye looks at a near object the IOL will shift its focal point to bring the near object into focus. Accommodating IOL’s achieve this by physically moving inside the eye in response to the focusing action of the muscles of the eye. The only FDA approved IOL of this type is called the Crystalens®. Patients implanted with the Crystalens® IOL generally enjoy near vision without glasses. The lenses don’t work well on patients with weak eye muscles. The eye muscles become weaker with age.
New technological advances in IOLs include lenses that allow patients to see both distance and close without wearing glasses. The ReSTOR® and TECNIS® Multifocal are the latest styles of IOL multifocal lenses that are designed to replace cataracts and correct presbyopia at the same time. As with many things, there may be a trade off. If you decide to have a multifocal IOL, your use of glasses may decrease, but at the cost of losing some of the sharpness of your vision. Even with glasses, this loss of sharpness may become worse under poor visibility conditions such as dim light or fog. There may also be some visual side effects such as halos and glare from lights at night that are more common than with a monofocal IOL. If you have significant astigmatism you may not be a good candidate for this style of lens.
