What Is A Cataract?
A cataract is the clouding of the eye’s naturally clear lens. The lens is part of the eye that helps focus light on the retina. The retina is a light-sensitive layer of tissue lining the inner surface of the eye. The optics of the eye create an image of the visual world on the retina through the cornea and lens. The clouding caused by a cataract reduces the sharpness of images reflected in the retina resulting in blurred vision.
Most cataracts are related to aging, usually starting at age 40. Cataracts are so common that by age 80 more than half of all Americans either have a cataract or have already had cataract surgery.
What Types of Cataracts are There?
There are three main types of cataracts:
- Cortical cataract
- Nuclear cataract
- Subscapular cataract
These aren’t the clearest to understand terms, so let’s try to break it down further. A cortical cataract occurs in the part of the lens surrounding the center of the lens. They are known for the white opacities that begin near the side of the lens, then move towards the center.
Nuclear cataracts, on the other hand, are typically connected to the aging process. They form deep in the nucleus of the lens.
Lastly, a subscapular cataract happens at the back of the lens. You have a higher chance of a subscapular cataract forming if you have diabetes or take high doses of steroid medications.
What Causes Cataracts?
As we know, cataracts form in the lens of the eye. This lens consists mostly of protein and water. In a healthy lens, the proteins stay out of the way, keeping the lens clear of obstruction and letting light pass through.
However, in some people, these proteins huddle together. This creates a cloudy formation in the lens. As this cloudiness grows, it can obscure vision, making things appear blurry.
While we understand under what conditions cataracts form, we know less about why these conditions occur. One common theory is that as we age, the oxidation level of the eye lens changes. The change in oxidation levels makes it easier for proteins to group, thus causing a cataract. This theory is backed by several studies showing that diets high in antioxidants, such as some fruits and vegetables, tend to prevent cataracts.
Beyond age, though, experts have come up with a list of risk factors that could act as causes of cataracts:
- Diabetes
- Exposure to ultraviolet radiation
- Hypertension
- Genetics
- Longterm use of some cholesterol medications
- Obesity
- Previous eye injury, inflammation, or surgery
- Smoking
What are the Symptoms of Cataracts?
Different types of cataracts can cause various symptoms. A subscapular cataract can develop with little or no symptoms until it’s fully grown. Nuclear cataracts, on the other hand, can improve near vision. This improvement is only short-term, though, and the common cataract symptoms will soon appear.
For instance, the first symptom you’ll experience is blurry vision. Many people describe the effect as if you were looking through foggy glass.
As your cataract continues to develop, you’ll start to find that some lights become too bright. When driving at night, headlights from oncoming traffic become more glaring. Additionally, once bold colors will begin to dull.
How Is My Vision Affected By Cataracts?
A cataract is caused by one of two changes in the lens: clumping of protein or discoloration. The lens is primarily composed of water and protein. In the case of cataracts, the protein clumps up in areas clouding the lens and reducing the amount of light that reaches the retina. This can start with small clumps and increase in size to completely cover the lens requiring cataract surgery.
In the case of discoloration the lens slowing changes to a yellow and/or brownish color. Over time this brown tint to the lens becomes more prominent making it difficult to read and identify colors such as blues, purples, and blacks. Gradual discoloration of lenses does not affect the sharpness of the image. The natural wear and tear on eyes due to job requirements, lifestyle, and environment are possible factors causing cataracts.
Can Cataracts Be Prevented?
There’s no tried and true method proven to eliminate your odds of developing a cataract during your lifetime. But we can look at the above risk factors for some ways to potentially reduce those odds.
Several studies have found that diet can play a role in preventing cataracts, for example. One study found that diets high in vitamin E, lutein, and zeaxanthin are associated with a lowered risk of developing cataracts. Lutein and zeaxanthin are two naturally occurring compounds that are found in green, leafy vegetables. You can find high levels of vitamin E in almonds, sunflower seeds, and spinach.
As UV radiation can help promote cataract growth, another easy prevention technique is to wear appropriate sunglasses whenever you’re outside. Ideally, this means sunglasses that shield your eyes from 100 percent of UV rays.
Can Cataracts Be Treated?
Many cataract treatments can help improve vision and reduce side effects. Blurriness can be treated with new glasses or added magnification, such as through strong bifocals. Improved visual aids and better lighting can also help with glare.
Surgery can be a scary word to some, but it is an effective treatment, especially as cataracts beings to disrupt your day-to-day routines. It’s a simple procedure that involves removing the cloudy lens and replacing it with an artificial lens. Typically, there is little to no pain involved with the surgery.
As technology continues to improve, so do the increased benefits to patients. For example, some new lenses can shield your eye from UV radiation, which we know to be a risk factor for cataract development.

An image-guided femtosecond laser allows our surgeons to make incisions with efficiency and precision without the use of a blade. The laser also assists in breaking up the cataract so that removal of this cloudy lens requires less ultrasound energy, which is easier on the eye. This new laser technology also allows for better management of our patient’s corneal astigmatism. This technique is available only with the premium lens implants, which ensures the best visual outcome for our patients. Our goal through this latest technology of laser-assisted cataract surgery along with premium lens implants is to increase the likelihood of patients not needing glasses following their cataract surgery. From the first incision to recovery, LenSx® serves as a superior alternative to traditional cataract surgery. A form of laser cataract surgery, LenSx® uses modern technology to make the process less intensive and more precise while providing benefits almost immediately. Traditional cataract surgery relies on the surgeon’s steady hands and deep concentration to make the first cut into the eye. If the surgeon’s mark is off, they may need to extend the incision. This larger cut will often require stitches to help close it. These stitches will remain on the eye for at least a week. LenSx®, though, uses micro-images of your eye to help the surgeon find the ideal incision spot. They can then use a laser to make a small, accurate cut. Furthermore, LenSx® only needs half the ultrasonic energy of traditional cataract surgery to help remove the damaged lens. This makes surgery less painful and incurs less trauma and inflammation. Because of its sophisticated computer mapping process, LenSx® can also insert the new lens, called an intraocular lens, more efficiently and accurately than typical cataract surgery. This makes recovery easier, with vision improving almost immediately after the surgery and without the added pain, discomfort, and other side effects of previous lens replacement processes. Multifocal IOL lens implants enable patients to see near, far and intermediate distances after surgery. With a multifocal IOL, the central portion of the lens has a series of steps that are carved in a very precise arrangement with varying step heights and distances between steps. Each of the steps of this diffractive optic bends the incoming light differently; creating a near focus that is quite separated from the distance focus formed by the remaining refractive portion of the lens. This large separation between the two images allows for fewer artifacts or distortion in either of the images, providing good quality of vision at both distance and near. Accommodating lens implants have garnered a significant amount of positive reviews and testimonials from thousands of early patient adopters. These special lenses are designed to mimic or accommodate, just like the eyes natural lens would. The hinge design of the lens enables it to move inside the eye just like the original natural lens. The end result is that patients can see better at multiple distances. The only accommodating IOL available is known as the Crystalens® by Bausch & Lomb. Toric lens implants are a unique type of lens implant that is used to correct astigmatism. A Toric lens implant is NOT the only method of astigmatism correction, so consult a doctor about the current possibilities. The asymmetric steepening of the cornea or natural lens causes light to be focused unevenly, which is the main optical problem in astigmatism. To individuals with uncorrected astigmatism, images may look blurry or shadowed. Astigmatism can accompany any form of refractive error and is very common. Astigmatism can be corrected with glasses, contact lenses, corneal relaxing incisions, laser vision correction, and special implant lenses. If a cataract patient has astigmatism and has aspirations to be glasses-free after surgery, the Toric lens implant is a good option. Toric lens implants are NOT a correction option for presbyopia. The AcrySof® Toric lens implant is a popular choice for this type of lens. Premium lens implants can be very exciting for patients that want to have a new level of spectacle freedom after cataract surgery, or with clear lens extraction. Due to the complex nature of each person’s visual system, it is difficult for a patient to make an assessment of the right lens without consulting a medical ophthalmologist. For years, patients who got cataract surgery had a successful outcome but still needed to wear glasses afterward. Traditional cataract surgery can fix long-distance vision or near vision, but not both. Now, there is a new option that can provide clear vision for near, intermediate, and far distances without needing to wear glasses or contacts. The new technology is called the PanOptix trifocal intraocular lenses. The PanOptix trifocal lens is the first and only trifocal lens in the United States. This technology has already been used successfully in countries around the world. It is changing lives and redefining post-cataract surgery outcomes for patients. More than 120 million people worldwide have benefitted from the trifocal intraocular lens. This lens has been available for several years before it received FDA approval in the U.S. While cataract surgery removes a patient’s cloudy lens with a new, clear lens, it is limited to providing clear vision at one or more distances. This depends on which intraocular lens the patient chooses. Cataract surgery patients are limited to a lens that will correct distance vision or near vision, but not both. While cataract surgery clears up blurry vision and side effects caused by cataracts, many patients find they still need glasses for near work or to see far distances. The PanOptix trifocal lens reduces the need for glasses as the first lens of its kind to provide correction at all three distances – near, intermediate and far. For the first time, you can imagine what life would be like without glasses and save the money you spend on glasses and contact lenses. The PanOptix trifocal lens is an advanced technology lens used to focus images clearly to the retina. This provides clear vision post-cataract surgery. It serves as a trifocal lens and provides more benefits that a monofocal cannot provide. This includes better vision while reading, working on a computer, or driving. It has better image quality over other trifocal lenses. Like other lenses, it is permanently placed in your eye. Unlike other lenses, the advanced technology maximizes the amount of light that reaches the retina. This gives patients crisp and clear vision at every distance. It also works under various lighting conditions. Your eye physician can set the intermediate vision focal point with PanOptix to a distance suited to your lifestyle. When the lens is implanted in the eye during cataract surgery, the eye and brain adjust to looking through the correct part of the lens. This depends on where the person is focusing. Unlike other multifocal lenses, the PanOptix trifocal lens delivers excellent contrast sensitivity. In the trifocal lens design, 50% of light energy goes to distance vision, 25% goes to intermediate vision, and 25% to near vision. The PanOptix trifocal lens works best for patients who want to be able see with ease. This is the case whether they are doing close work like reading, intermediate work, such as typing on a computer; or seeing far away, such as playing golf. If you are a candidate for cataract surgery, you can consider choosing a PanOptix trifocal lens. It’s best to schedule an appointment with your eye doctor who has experience with multifocal intraocular lenses to determine if it is right for you. At Willis Knighton Eye Institute, whether you’re in Shreveport, Coushatta, or Natchitoches, you can discuss your vision goals with an experienced eye physician. Your doctor will discuss all your cataract surgery options with you. Willis Knighton Eye Institute is the first eye care practice in Louisiana to offer the PanOptix trifocal lens to patients. Some patients opt for a monofocal intraocular lens, which allows clear vision at one distance – either near or far. Those patients continue to wear glasses after cataract surgery. Another option is that one eye receives an intraocular lens for distance and the other for close vision. With this option, a patient must use one eye at a time for each distance. This will reduce the need for some glasses but may affect depth perception. Deciding on the correct intraocular lens is an important decision. You should take into account your vision goals, lifestyle, and other health issues. Exploring your options is best-done face-to-face with an experienced eye physician. We at the Willis Knighton Eye Institute are one of the few practices that offer trifocal lenses to our cataract patients. In some instances, patients may still need glasses for intricate, detailed, or close work. Be sure to discuss that possibility during your consultation with your eye doctor. During clinical trials with the trifocal lens, some patients reported temporarily experiencing glare, including halos around lights. This was most noticeable at night and decreased or became less noticeable over time. Once your first eye is implanted with a PanOptix Trifocal lens, your vision may not be completely clear until you have the lens put in your second eye. After treating the second eye, patients reported having good vision at near, intermediate and far distances. This happened within a few days of surgery. Some people take a little longer to adapt to their new vision than others, so stay in touch with your eye doctor after cataract surgery. On rare occasions, your eye surgeon may recommend a minor “touch up” procedure to refine your vision. Once your post-cataract surgery vision has settled, you can enjoy routine activities without the need for glasses. Because the PanOptix trifocal intraocular lens is a premium lens, it may not be covered by your insurance plan or Medicare. Our billing and insurance office is available to discuss different options for you. Wondering if the PanOptix trifocal lens may be right for you?

ORA System™ has been helping doctors deliver the best possible outcomes to their laser cataract surgery patients. The ORA system offers many benefits to both doctors and patients, such as: ORA System™ is a big advancement in eye lens surgery, allowing doctors to make the best choices during surgery as to what will benefit your eyesight the most. The ORA system is especially helpful in astigmatic patients. Because ORA uses Wavefront technology to analyze imperfections in the eye and what is causing a refractive error, your surgeon knows exactly what needs to be corrected. Also, ORA can tell during surgery whether or not the eye is focused, and if it is not, the ORA System helps the surgeon focus the eye. What is ORA Technology? ORA technology is a state-of-the-art system that helps eye surgeons make decisions in real-time when conducting cataract surgery. When cataract surgeons use ORA, which stands for Optiwave Refractive Analysis, it leads to better outcomes during and after surgery. How Does ORA Work? When you undergo cataract surgery, your surgeon will remove the cloudy lens and replace it with an implant called an intraocular lens implant or IOL. Before the ORA system, to ensure the new lens gave you better vision, surgeons relied on a series of manual measurements that could only be taken before they removed the original lens. This created wide margins of error that couldn’t be calculated until several weeks had passed post-surgery. ORA, though, is a medical and technological breakthrough. When attached to a surgical microscope, it conducts dozens of calculations to measure the refractive power of the eye once the cataract is removed. This real-time calculation gives surgeons the ability to better ensure the new lens properly addresses the issues the surgeon is attempting to fix. As these calculations can be done in real-time, the new implant can be precisely placed and reduce the margins of error. This helps reduce the need for glasses or other corrective equipment after surgery. Who Is a Candidate for ORA? ORA makes it far easier to perform cataracts surgery by increasing precision during surgery and reducing complications post-surgery. This means it can be helpful to almost all patients who suffer from cataracts. Those most likely to benefit from ORA typically have complicated cases of cataracts. These pre-surgery complications can stem from a variety of issues and conditions: Why Should Cataract Patients Choose ORA? Cataract surgery is fairly common, with over two million people a year undergoing it to improve their vision. As technologies and methods continue to push into new frontiers, patients are increasingly likely to choose cataract removal procedures that reduce complications, improve success rates, and prevent the need for additional corrective measures. As technologies and methods continue to push into new frontiers, patients are increasingly likely to choose cataract removal procedures that reduce complications, improve success rates, and prevent the need for additional corrective measures. This makes ORA cataract surgery an excellent option for those with cataracts who are looking to restore their vision.Finding The Best Eye Surgeon For Your Procedure
