This multifocal approach to vision restoration allows many patients to experience life with significantly reduced reliance on glasses or contact lenses.
Pepose Vision Institute’s comprehensive cataract treatment methodology combines thorough preoperative evaluation with customized surgical planning, ensuring each patient receives personalized vision correction tailored to their lifestyle needs. The practice’s commitment to advanced cataract surgery techniques positions patients for optimal visual outcomes and enhanced quality of life.
What Are Cataracts?
Inside our eyes, we have a natural lens. The lens bends (refracts) light rays that come into the eye to help us see. The lens should be clear. A cataract is a clouding of this usually clear, transparent lens of the eye.
A cataract is not a tumor or growth of new tissue over the eye but rather a fogging and loss of clarity of the lens itself. When a cataract forms, the lens can no longer focus the light clearly, resulting in your vision becoming cloudy. Things look blurry, hazy, or less colorful with a cataract. Some other vision changes you may notice include:
- Double vision
- Extreme sensitivity to light
- Trouble with night vision
- Seeing bright colors as faded or yellow
Early-stage cataracts typically cause minimal vision problems. However, as the condition progresses, patients may experience partial or complete vision loss that persists until surgical intervention. Cataract surgery addresses this issue by removing the cloudy natural lens and replacing it with a clear artificial lens, thereby restoring sight.
What Causes Cataracts?
Although cataracts result from many conditions, the most frequent cause is the natural aging process. Other causes may include eye trauma, chronic eye disease, and other medical conditions such as diabetes. As we age, our eyes change in a gradual, predictable manner. During this time, the lens begins to break down its normal proteins; this causes cloudy lenses. By the time people reach their 60s, their lenses have usually started to cloud. Despite this, vision problems are not always immediately apparent.
Cataracts can take from a few months to several years to develop. Certain medications can accelerate the development of cataracts. Sometimes, the cataract stops developing in its early stages and vision is only slightly decreased. But if it continues to develop then it impairs vision and requires surgical removal.
Pepose Vision is a worldwide leader in the research of cataract treatment and removal. We utilize the latest technology and provide the convenience of a surgery center in our building. Our surgeons are involved in your entire surgical process, including pre-op, and are recognized each and every year among the very best.
How Do I Know If I Have Cataracts?
You may not notice any symptoms with early cataracts. As a cataract becomes more advanced you will notice a decrease in vision, not fully correctable with glasses. Contrast sensitivity is lost, so that shadows and color vision are less vivid. You may note more glare as light into the eye is scattered by the cataract. You may also observe halos around lights. Night vision will be diminished. In certain types of cataracts, double vision may be noted in the affected eye. Some patients note that they require frequent changes in their eyeglass or contact lens prescriptions and may be aware that their near vision is improving as their distance vision declines.
A cataract does not routinely cause discomfort or pain in the eye or alter the external appearance of the eye.
The only way to determine if your vision issue results from a cataract is to visit an eye care professional for a complete eye exam. We use state-of-the-art diagnostics to evaluate your eyes. Our wavefront diagnostic technology generates thousands of data points about your eyes in a matter of minutes. We are the only cataract surgeons in the greater St Louis area to provide this level of thoroughness during your exam.

How Are Cataracts Treated?
The only effective cataract treatment is surgery to remove the diseased, cloudy lens. Neither diet nor medications have been shown to stop cataract formation.
In a cataract operation, we remove the eye’s natural lens. Vision can then be obtained by implanting a permanent intraocular lens (IOL). This replaces the natural lens. This artificial lens is made of plastic and is usually inserted at the same time the cataract is removed. Depending on the individual case, the lens is placed directly behind or sometimes in front of the iris. The iris is the “colored” part of the eye.
There have been remarkable advances in cataract treatment. Premium lenses (IOLs) now not only help make vision clearer but can also help improve near and far vision. Often patients that select these lenses do not need to use their glasses anymore.

Choosing Your Cataract Surgery Provider
We know that “one size does not fit all.” We’re one of the first in the nation to offer the latest diagnostic and surgical technologies to our cataract patients.
We’ve worked with some of the leading developers of eye technology to perfect both the technology and the procedure, and our state of the art diagnostic tests for cataract surgery are the most advanced available today. These tests, and our unparalleled experience in interpreting the results, ensure that your procedure is tailored exactly to your needs.
Though cataract surgery has become “routine” in terms of occurrence, it is still SURGERY. We recommend that the best way to ensure a successful outcome is to choose a highly experienced surgeon who is involved in developing state-of-the-art treatments to enhance your vision outcome.
Why Have Cataract Surgery At Pepose Vision
Our State-Of-The-Art Cataract Diagnostic Tests
A Wavefront analyzer objectively measures tiny aberrations in the optics of the eye, in addition to accurately measuring the degree of near or far-sightedness and astigmatism. Tiny aberrations in the eye cause some patients to complain that the letters on an eye chart appear “ghostly”, that headlights at night have “tails” on them, and that streetlights have “halos” — factors that are not as readily correctable with contact lenses or glasses.
Wavefront analysis generates thousands of complex data points that must be accurately interpreted to have a beneficial impact on your vision correction surgery. This technology derives directly from the optics advances used to create and fix the Hubble space telescope.
Our wavefront analyzer accurately assesses your nearsightedness, farsightedness and astigmatism in a matter of seconds, simply by having you look into a target image in the machine (nothing touches the eye). This process eliminates the subjectivity introduced when a patient is asked, “Which image is better, number one or number two?” The accuracy of our wavefront analyzer is 25 times greater than this subjective approach, meaning that the calculations we use in determining the appropriate lens implant will inevitably be 25 times more accurate as well! Over the past four years, applying wavefront analysis to our cataract patients has led a vast majority to achieve uncorrected vision of 20/20 or better and has substantially improved the quality of their nighttime vision.
Our doctors have had the most experience in the region in applying wavefront analysis pre-operatively to enhance our surgical outcomes. We are one of only a handful of practices nationwide to perform this analysis on our cataract patients at no additional charge! Our clinical studies have contributed to advancements in wavefront analysis, including 3-dimensional versus 2-dimensional results.
Pepose Vision is one of just a few centers in the nation to evaluate all of its patients using both the Orbscan and Atlas corneal topography instruments. Topography is a way to measure the shape of the cornea. We evaluate your cornea at over 8,000 points and the various elevations are then represented color maps. Just as the height of land can be viewed from a helicopter circling above, the elevated peaks of the cornea can be printed in hot colors such as red and orange, and the valleys printed out in cool colors such as blue.
Using the Orbscan device, we measure both the front and back surfaces of the cornea. Its thickness at all locations can be plotted out and a 3 dimensional reconstruction of the shape of the eye can be created that can be rotated and viewed by our surgeons at all angles. The Orbscan instrument, coupled with the Atlas topographer, gives us a better understanding of pre-existing eye conditions. This information is crucial to calculating the very best lens implant for each patient’s eyes, resulting in crisper vision. This is particularly important for patients who have had LASIK or other forms of vision correction surgery.
The Atlas topography device provides specialized computerized screening to rule out a progressive condition of the cornea called keratoconus, which can also affect cataract outcomes and intraocular lens calculations.
As cornea subspecialists, our surgeons have the experience and know-how to appropriately use this pre-operative information to assure our cataract patients the very best outcome possible.
Each and every patient who has cataract surgery at Pepose Vision Institute benefits from the Holladay Professional Surgical Outcomes Program, which assures that your lens implant will be precisely calculated using advanced mathematical relationships. The accuracy of your lens calculation requires careful measurement of the length of your eye and ocular structures, the thickness of your lens and shape of your cornea. Only the most meticulous pre-operative information can assure you the very best outcome that cataract surgery has to offer.
Historically, eye doctors measured the eye’s length by applying a probe to compress the front of the eye. With A-Scan Biometry, we use a gentle water bath technique called Immersion A-Scan. With this newest technology, the ultrasound probe does not come into direct contact with the cornea. We use this diagnostic test to confirm your intraocular lens calculations as well as assess lens thickness. It is especially useful in cases where patients have very dense cataracts.
The FDA has approved new tools for measuring the dimension of the eye prior to cataract surgery, such as the IOL Master Lenstar. These laser systems offer the most precise measurement of eye length and surface curvature, greatly enhancing the accuracy of each patient’s intraocular lens calculation. This is done without ever touching the eye and within a minute or two. Simply put, this is the most accurate method now available to ensure that our cataract patients have the very best vision outcome possible.
Advanced Surgical Cataract Removal Procedures
Our surgeons have had a great deal of experience using the latest foldable lenses to replace the natural lens of your eye. These lenses permit the lens exchange to occur through a micro-incision, thereby eliminating the need for stitches. The result is less discomfort after surgery and a faster recovery period.
Whenever possible, our surgeons will use topical anesthesia to perform cataract surgery instead of using shots to deliver anesthesia. Initially, cataract surgery was performed under general anesthesia, requiring patients to stay in the hospital. Later advances led to the use of a local anesthesia injected behind the eyeball. Although this procedure allows patients to return home the same day and is safer than general anesthesia, it is not entirely free of risk.
We use the safest, most advanced anesthesia system available. When medically advisable, we anesthetize your eye using eye drops rather than through an injection of anesthetic under the eyeball with a needle. Avoiding the needle reduces the risk of bleeding, bruising and inadvertent damage from the needle itself. Moreover, visual recovery begins immediately since the eye muscles are not paralyzed as with local block anesthesia. Even when topical anesthetics are used, patients may be given an IV sedative to help them relax and keep them comfortable during the procedure.
Until recently, a monofocal intraocular lens, which cannot change shape, has been the standard implant for cataract surgery. Its power is usually calculated to maximize a patient’s distance vision so that the patient can see well enough to do most things without glasses. Reading glasses must still be worn to see up close up. In most cases, patients notice rapid and significant improvements in vision as a result of the IOL.
In 2005, the FDA approved the first major innovation in IOL technology in decades the deluxe multifocal “accommodating” IOL. This implant, which replaces the natural lens in the same fashion as the monofocal lens, gives good “walk around” distance and near vision, thereby lessening dependence on glasses. The FDA has approved a number of multifocal lens, each of which has been optimized for a slightly different vision zone. We’re the only cataract surgery practice that has been certified to offer all four of these lenses Crystalens, Restor, Symfony and Technis multifocal lens and was among the first in the nation to offer these IOLs. This gives our surgeons a unique opportunity to “mix and match” the lenses used in each of your eyes and to personalize your vision outcome for your unique lifestyle
