Intraocular Lens Options
Cataracts develop when the natural lens of your eyes become cloudy, affecting your sight. When a cataract causes your quality of vision to interfere with your daily activities, cataract surgery is recommended.
After the cataract is removed, it is replaced with an intraocular lens implant that is similar to a small soft contact lens which contains an optical prescription that is matched for you, much like your glasses.
If you are diagnosed with cataract formation, Dr. Boozalis in Victoria wants you to know that there are different intraocular lens options available for you.
- Monofocal lens: These lenses are the most commonly implanted lenses today. They have equal power in all regions of the lens and can provide high-quality distance vision. Monofocal lenses are in sharpest focus at only one distance. They do not correct pre-existing astigmatism, a result of irregular corneal shape that can distort vision at all distances. People with significant astigmatism require corrective lenses for sharpest vision at all distances. Patients who have had monofocal intraocular lenses implanted usually require reading glasses.
- Toric lens: Toric lenses have more power in one specific axis in the lens to correct astigmatism as well as distance vision. Due to the difference in lens power in different areas, the correction of astigmatism with a toric lens requires that the lens be positioned in a very specific configuration. While toric lenses can improve distance vision and astigmatism, the patient still will require corrective lenses for all near tasks, such as reading or writing.
- Multifocal lens: Multifocal intraocular lenses are one of the latest advancements in lens technology. These lenses have a variety of regions with different power that allows some individuals to see at a variety of distances, including distance, intermediate, and near. While promising, multifocal lenses are not for everyone. They can cause significantly more glare and loss of contrasts than monofocal or toric lenses. Multifocal lenses cannot correct astigmatism, and some patients still require spectacles or contact lenses for clearest vision.
