Awesome Choices for Cataract Replacement Lenses
- Posted on: Dec 15 2019
Cataracts, a gradual clouding of the lenses of the eyes, is a common condition, especially among those over age 60. At Insight Eye Center, Dr. Rom has performed over 25,000 surgeries to remove cataract-clouded lenses and replace them with intraocular lenses. It’s a big part of what we do at Insight. And we’re excited because the replacement lens choices keep getting better and better as new technologically advanced models are introduced.
There are many factors that can cause a patient to develop cataracts, where the lens, found behind the iris and the pupil, becomes clouded: aging, eye trauma, excessive sun exposure, disease inside the eye, family history, smoking, diabetes, and poor nutrition. No matter the underlying cause, it’s important to trust the experience of Dr. Rom and his team at Insight to remove your clouded natural lens or lenses and replace them with new implanted artificial lenses.
What are the symptoms of cataracts?
Most patients who are developing cataracts don’t really realize the increasing cloudiness caused by protein building up in the lens. The changes are very gradual. Cataracts will continue to progress, usually without pain, but there will be other symptoms:
- Blurred or hazy vision
- Double vision
- Poor vision in bright light
- Seeing halos around lights
- Poor night vision
- Yellowish tinged vision
- Need for frequent prescription changes in eyeglasses or contact lenses
Lens choices for cataract replacement
Surgery is the only way to remove a cataract. The clouded lens will be replaced with an artificial lens called an intraocular lens implant (IOL). The offerings for IOLs are broken down below, but there are new options coming out seemingly all the time. The latest multifocal lens choices even can correct for presbyopia, the condition completely unrelated to cataracts or refractive errors where eyes over the age of 40 have more and more trouble focusing for up close vision. Presbyopia is the reason you’ll find seemingly endless pairs of reading glasses throughout the homes of older people.
- Monofocal lens implants– This was the only original replacement lens option. These lenses only offer vision at one distance — far, intermediate, or near — so the wearer will need glasses either for up close or distance vision. The focal distance can be set to the distance chosen by the patient. It may be set for both eyes to either see at a distance, such as for driving or maybe watching TV; or for near vision, such as reading and using a computer. Or, one eye can receive an IOL that provides near vision and the other eye an IOL that provides distance vision. Most people can adjust to this seemingly disjointed arrangement, as the brain adjusts and filters the incoming stimuli according to the vision needed.
- Multifocal lens implants– These newer lenses allow the patient to see well at more than one distance, without glasses. They are considered to be “premium” lenses because of the extra benefits that are unavailable in monovision IOLs.
- Accommodating lens implants– Accommodating implants shift with the action of the eye muscles to increase focusing ability. These lenses offer excellent vision at all distances.
- Toric lens implants– These lenses not only replace cataract-clouded lenses, but also correct astigmatism. There are various options depending on the amount of astigmatism to be corrected. In 2013 the FDA approved the first accommodating toric IOL.
