I’ve been seeing Dr. Griffiths and her staff for years. Always excellent care and service. Cataract surgery was a success. While frames are pricier, convenience and insurance make it worth it. Highly recommended!

Posterior Subcapsular Cataracts: What You Need to Know
Causes and Risk Factors
PSC cataracts have several known causes beyond normal aging. Identifying your personal risk factors helps our team watch for early changes and plan care proactively.
Corticosteroid medications are among the most common non-age-related causes of PSC cataracts. Steroids taken by mouth, applied to the skin, inhaled for conditions like asthma, or used as eye drops can all contribute to PSC development. The risk increases with higher doses and longer duration of use. If you take steroids for a chronic condition, regular monitoring of your lens is an important part of your eye care.
Elevated blood sugar accelerates protein changes inside the lens, making people with diabetes more likely to develop PSC cataracts at a younger age and at a faster rate. A process called glycation, where sugar molecules attach to lens proteins, disrupts the normal structure of the lens and can create opacities over time. While controlling blood sugar can help slow this process, it does not reverse changes that have already occurred. Our team coordinates your cataract monitoring with your overall health management when diabetes is a factor.
Blunt or penetrating eye injury can damage the posterior lens capsule and lead to PSC formation. Radiation therapy to the head or neck area is another recognized cause, as is chronic uveitis, which is ongoing inflammation inside the eye. Prior vitrectomy surgery and high myopia, meaning significant nearsightedness, are also associated with an increased risk. Our team will identify which risk factors apply to you and set a monitoring plan that fits your situation.
Symptoms and Diagnosis
PSC cataracts produce a recognizable pattern of symptoms that often affect daily activities well before the cataract reaches an advanced stage. Understanding what to look for can prompt earlier evaluation and better outcomes.
PSC cataracts tend to impair near vision before distance vision, making reading, screen use, and close work progressively more difficult. Bright light causes significant glare because it passes directly through the posterior opacity, often creating halos or starburst patterns around light sources. Many patients notice their vision is worse in sunlight or under bright indoor lighting and somewhat clearer in dimmer conditions, which is the opposite of what people with nuclear cataracts typically experience. These symptoms can worsen over weeks to months as the opacity grows.
Our team identifies PSC during a dilated slit-lamp examination, a standard in-office test that allows a detailed view of the back surface of your lens. The opacity may appear granular or plaque-like and is typically located directly behind the center of the pupil. Your Cataract Surgeon grades the severity based on the size and density of the clouding. Advanced imaging technology can document the PSC so that changes can be tracked accurately over time and compared at future visits.
Surgery is typically recommended when your PSC cataract interferes with activities that matter to you, such as reading, driving in bright conditions, or using a computer. Because PSC cataracts progress more quickly than other types, your Cataract Surgeon may recommend surgical evaluation sooner after the initial diagnosis. The decision is always made based on your specific symptoms, your vision needs, and how the cataract is affecting your quality of life.
Treatment and Surgical Outcomes
Cataract surgery is highly effective for PSC cataracts, and most patients experience meaningful vision improvement. Understanding what the procedure involves and what to expect afterward can help you feel prepared.
Your Cataract Surgeon removes the clouded natural lens using phacoemulsification, a technique that uses ultrasound energy to gently break up and remove the lens. Once the natural lens is removed, a clear intraocular lens (IOL) is placed inside the eye to restore vision. Our team at NewView Eye Center uses the LENSAR femtosecond laser system for laser-assisted cataract surgery, and we offer a full range of premium IOL options including the PanOptix Pro, TECNIS Odyssey, enVista Envy, TECNIS PureSee, Clareon Vivity, and TECNIS Symfony, among others. Your Cataract Surgeon will discuss which lens option is the best fit for your vision goals and lifestyle during your consultation.
During PSC cataract surgery, your Cataract Surgeon works with particular care around the posterior capsule, since the opacity sits directly on this delicate structure. Preserving the integrity of the posterior capsule during the procedure supports excellent visual outcomes. When the capsule remains intact, results after PSC surgery are typically very good, and most patients see a significant improvement in both near vision and glare sensitivity.
Most patients notice a marked improvement in reading ability and a reduction in glare within the first few days after surgery. The bright-light sensitivity that was characteristic of your symptoms resolves once the posterior opacity is removed along with the rest of the natural lens. Colors may also appear brighter and more vivid through the new clear IOL. Your Cataract Surgeon monitors your healing closely during follow-up visits to confirm your recovery is on track.
If you take corticosteroids for an ongoing condition, it is important to discuss monitoring strategies with both your Cataract Surgeon and the physician who manages your medication. Continued steroid use does not affect the IOL itself, but it can contribute to a condition called posterior capsule opacification (PCO), which is a clouding of the membrane behind the IOL. If PCO develops, it is treated with a quick, painless laser procedure in the office. Attending regular follow-up exams, protecting your eyes from UV exposure, and managing conditions like diabetes all support your long-term vision after surgery.
Frequently Asked Questions
These are some of the questions patients most often ask when they learn they have a posterior subcapsular cataract. If you have additional concerns, our team is happy to walk you through them during your visit.
Once your natural lens is removed and replaced with an IOL, a PSC cataract cannot re-form on that lens. However, some patients develop posterior capsule opacification (PCO) in the months or years after surgery. PCO can cause symptoms similar to your original cataract, but it is not the same condition and is treated quickly and painlessly with a YAG laser procedure right in the office. Staying consistent with your follow-up appointments makes it easy to catch and address PCO early.
Never stop a prescribed medication without speaking to the doctor who prescribed it first. Your Cataract Surgeon can communicate with your prescribing physician to discuss whether dosage adjustments or alternative medications might reduce the impact on your lens while still managing your underlying condition. After surgery, your IOL is not affected by steroid use, though your eye health should still be monitored regularly.
The rate of progression varies by person and is influenced by factors such as steroid use and blood sugar control. For some patients, vision changes can become noticeable over a period of months rather than years. This is one reason prompt evaluation matters, since earlier detection gives you more time to plan surgery on a schedule that works for you rather than being caught off guard by a rapid decline.
Whether you need reading glasses after surgery depends on which IOL you choose and your specific vision profile. Standard monofocal lenses correct vision at one distance, and many patients with a monofocal IOL still use reading glasses for close work. Premium multifocal and extended depth-of-focus lenses, like those we offer at our practice, are designed to reduce dependence on glasses at multiple distances. Your Cataract Surgeon will help you choose the option best suited to your needs and expectations during your pre-surgical consultation.
PSC cataract surgery is elective, meaning there is typically no medical emergency requiring you to act immediately. That said, because PSC cataracts progress faster than other types, waiting too long can mean a more significant drop in your quality of life before surgery takes place. If your symptoms are affecting your ability to read, drive safely, or carry out daily tasks, scheduling an evaluation sooner rather than later is a reasonable and practical step.
PSC cataracts do not always affect both eyes at the same rate, and one eye may be more advanced than the other. If your risk factors, such as steroid use or diabetes, apply to both eyes, your Cataract Surgeon will examine both during each visit. Surgery is typically planned for one eye at a time, and your surgeon will guide you on the appropriate timing for the second eye based on your individual situation.
