Cataracts develop over years, and early changes are easy to blame on tired eyes, dim lighting, or outdated glasses. According to the National Eye Institute, more than half of Americans age 80 and older either have cataracts or have had surgery to remove them.
At The Omaha and Lincoln Eye and Laser Institute, a leading provider of cataract care in Omaha and Lincoln, eye surgeons regularly see patients who waited longer than necessary because they didn’t connect their symptoms to a cataract. Below are seven of the most common signs, along with how eye doctors decide when cataract surgery makes sense.
1. Blurry or Cloudy Vision
Many patients describe cataract vision as looking through a foggy or smudged window, and cleaning your glasses doesn’t help. Because blurry vision caused by cataracts builds over months or years, people often adapt without realizing how much detail they’ve lost.
2. Glare and Halos Around Lights
Bright sunlight and overhead lights may start to feel harsh. The clouded lens spreads light across the retina instead of focusing it, so light sources can appear surrounded by halos or starbursts. Some patients begin squinting indoors or avoiding bright rooms without knowing why.
3. Trouble Seeing at Night
Night vision is often one of the first things to change. In low light, your pupil widens and lets more light pass through the cloudy parts of the lens. Oncoming headlights can become blinding, and road signs may be unreadable until you’re close. Some patients can keep driving safely with cataracts for a while by avoiding the conditions that bother them most, such as driving toward a rising or setting sun. If night driving feels unsafe, stop until you’ve had an eye exam.
4. Faded or Yellowed Colors
As a cataract develops, the lens often takes on a yellow or brown tint. Whites look cream-colored, blues and purples become harder to tell apart, and colors lose their vividness. Because the shift is so subtle, many patients only notice it after surgery, and they’re surprised by how bright colors look again.
5. Frequent Changes to Your Glasses Prescription
A cataract can change how the lens bends light, which shifts your prescription. If you need new glasses every year, or new glasses don’t seem to help, a cataract may be the reason. Some people experience “second sight,” a temporary improvement in near vision that lets them read without glasses again. It may feel like a welcome change, but it usually signals a developing cataract.
6. Double Vision in One Eye
Most double vision involves both eyes and comes from alignment problems. Cataracts can cause a different kind, with double or ghosted images in one eye even when you close the other eye. Irregular clouding in the lens splits incoming light into multiple images on the retina.
7. Needing More Light to Read
If you’ve switched to brighter bulbs or started holding books near a window, reduced contrast may be the cause. Cataracts make it harder to separate print from the page, especially in dim restaurants or with gray text on white paper.
Symptoms That Point to Something Else
Cataracts are painless, and they almost always develop over a long period. That pattern matters, because some vision changes need faster attention. Sudden vision loss, eye pain, a shadow moving across your vision, or a burst of new floaters and flashes are not typical cataract symptoms. They can indicate acute angle-closure glaucoma or a retinal detachment, both of which require prompt care.
Glaucoma is sometimes confused with cataracts, but cataracts and glaucoma differ in an important way. Optic nerve damage from glaucoma is permanent, while vision lost to a cataract can be restored with surgery. If a symptom appears suddenly or comes with pain, contact your eye doctor right away instead of waiting for a routine visit.
When to Consider Cataract Surgery
A cataract diagnosis does not always mean you need surgery right away. In the early stages, an updated prescription, anti-glare lens coatings, and brighter lighting can keep vision functional for some time. Surgery becomes the recommended option once the cataract starts limiting what you need and want to do.
Your doctor will ask how your vision affects specific activities, because the signs you’re ready for cataract surgery show up in everyday life more than on an eye chart. Expect questions like these at your cataract consultation:
- Do you avoid driving at night or in the rain?
- Is reading, cooking, or computer work harder than it used to be?
- Have you given up hobbies like golf, sewing, or fishing because of your vision?
- Do you feel less steady on stairs or curbs?
- Has your vision failed to improve with new glasses?
If you answer yes to several of these, surgery is worth discussing. Waiting offers no benefit once a cataract interferes with daily life, and very dense cataracts can be more complex to remove.
In some cases, there is also a medical reason to act sooner. A dense cataract can block the doctor’s view of the back of the eye. For patients with macular degeneration or diabetic retinopathy, that makes it harder for retina specialists to monitor and treat those conditions, so cataract removal may be recommended earlier.
What to Expect During Cataract Surgery
Cataract surgery replaces the clouded natural lens with a clear artificial lens called an intraocular lens (IOL). The outpatient procedure usually takes 20 to 30 minutes in Omaha Eye’s accredited surgery center. Patients go home the same day, though you’ll need someone to drive you. When both eyes need surgery, they are treated on separate days so the first eye can heal.
The practice offers laser-assisted cataract surgery with the LenSx laser, which creates a detailed 3-D image of the eye and makes precise, computer-guided incisions. The laser also softens and divides the cataract, so it takes less ultrasound energy to remove.
Before surgery, you’ll choose an IOL. A standard monofocal lens provides clear vision at one distance, and most patients still wear glasses for some tasks. Premium options include toric lenses to correct astigmatism, multifocal lenses for clear vision at multiple distances, and the Light Adjustable Lens, which your eye doctor fine-tunes with light treatments after healing. Your cataract surgeon will recommend a lens based on your eye health and how much you’d like to reduce your reliance on glasses.
