Cataracts: Symptoms, Causes and When Surgery May Be Needed

Cataracts are something that the majority of us will develop as we age, but modern technology and medicine make cataract treatment — which typically means surgery — easier and more successful than ever. While cataracts and cataract surgery are considered relatively routine at this point, it’s still important to familiarize yourself with the signs and symptoms of cataracts — including dull colors, trouble seeing at night, and halos around your vision. Knowing that it may be time for cataract surgery matters because the sooner cataracts are treated, the sooner you regain clearer vision and independence for things like driving or working. Here, Dr. Scott Campbell and our caring team at SPEX share helpful information about the basics of cataracts, from causes and symptoms to treatment options in Seattle, WA. 

 

What causes cataracts? 

Cataracts occur when the normally clear lens inside the eye becomes cloudy over time, preventing light from passing through properly. Aging is by far the most common cause of cataracts, which is why they become increasingly prevalent later in life. However, several additional factors may contribute to cataract development, including:  

• Natural aging 
• Diabetes 
• Smoking 
• Excessive UV exposure 
• Previous eye injuries 
• Long-term steroid use 
• Certain medical conditions 
• Family history of cataracts 

While cataracts in Seattle cannot always be prevented, routine eye exams can help identify them early before they significantly impact vision. 

 

What are the most common cataract symptoms? 

Cataracts often develop gradually, which can make early symptoms easy to overlook. Many patients initially assume they simply need an updated glasses prescription before learning that cataracts are responsible for their vision changes. Common symptoms of cataracts include:  

• Blurred or cloudy vision 
• Difficulty seeing at night 
• Increased sensitivity to glare 
• Halos around lights 
• Faded or dull colors 
• Frequent prescription changes 
• Double vision in one eye 
• Difficulty reading or driving 

 

When is it time to get cataract surgery in Seattle? 

The decision to pursue cataract surgery is usually based less on the cataract and more on how much it affects your daily life. Cataract surgery may be recommended when vision changes begin interfering with activities such as:  

• Driving, especially at night 
• Reading 
• Working 
• Watching television 
• Using digital devices 
• Participating in hobbies 
• Maintaining independence and safety 

One of the most important roles of routine eye care is monitoring cataract progression over time. Through comprehensive eye exams, Dr. Campbell can diagnose cataracts, track changes in your vision, and help determine when a referral for cataract surgery evaluation may be appropriate. 

 

How long can you delay cataract surgery? 

In many cases, cataract surgery is not immediately necessary after a diagnosis. Some patients continue functioning comfortably for years with mild cataracts using updated eyeglass prescriptions, improved lighting, and other adjustments. However, delaying surgery for too long may eventually make daily activities more difficult and reduce quality of life. The key is ongoing monitoring. Again, regular eye exams allow us to assess whether cataracts are progressing and whether treatment discussions should begin. Every patient is different, which is why individualized follow-up care is so important. 

 

Will I have 20/20 vision after cataract surgery? 

Many patients experience significant vision improvement after cataract surgery, but achieving 20/20 vision is not a given. Visual outcomes depend on several factors, including overall eye health, preexisting eye conditions, the type of intraocular lens (IOL) used during surgery, and individual healing characteristics. Before surgery, patients typically undergo a thorough evaluation to determine realistic expectations. Even if perfect vision is not achieved, most patients report substantial improvements in clarity, brightness, and overall quality of vision following cataract treatment.
