Glossary: Cataract Surgery is the removal of the natural lens of the eye and replacement with an Implant Lens or Intra-Ocular Lens (IOL) that helps to restore vision. Recent advances in implant lens technology have allowed doctors to develop bifocal lenses such as the ReSTOR® , Tecnis® and Crystalens® accommodating lenses that can help patients regain near vision as well as distance vision. Refractive Lens Exchange is the same surgery as cataract surgery, but done primarily to eliminate refractive errors such as nearsightedness and farsightedness, as well as to restore Near Vision.
More than 2 million people have cataract surgery each year, making it one of the most commonly performed surgeries in the United States. A Cataract occurs when the lens inside the eye becomes milky or cloudy. Once this happens, glasses are no longer able to help the eye focus. Eventually this cloudiness progresses to the point where cataract surgery is needed.
Common symptoms of a cataract include: night-time glare from headlights, difficulty driving with the sun low in the sky, difficulty reading fine print, and a muting of colors. The solution is to remove the cataract and place an implant lens in its place to restore the focusing ability of the eye.
The Cataract Surgery Procedure & Experience
After a thorough cataract eye exam, our doctors will discuss planning and preparing for your eye surgery. Typically we do your worst eye first, and the other eye if needed a few weeks later. You will be measured for your implant lenses and receive a thorough history and physical a few days before surgery. Eye Laser and Surgery Center is where your surgery will take place—directly across the hall from our Stahl Vision Clinic. Upon your arrival at the surgery center you will be given a mild sedative, and drops will be put in your eye. You will need a driver for the day of your surgery, and plan on being at the center for 2 hours.
At the beginning of the surgery, Drs. Stahl or Knowles will place a very small incision in your eye and carefully breakup and remove the cloudy cataract affected lens. After cleaning and polishing the capsule inside your eye that holds the lens, a flexible foldable implant lens is placed into the capsule where the haptics or “arms” unfold and hold it into place. How you see for distance and near vision is dependent on the implant lens you choose for your surgery.
With the cataract removed, and the implant lens in place, light can once again travel unimpeded into your eye for clearer vision. At the end of surgery antibiotics and ointment is placed in your eye and the eye is patched for a short while. You can head home and take a nap after your cataract surgery, and start your eye drops that you will be using for a few weeks after as the eye heals.
Most people are blurry for a day, but as the swelling from surgery recedes your vision will continue to improve.
Advanced Cataract Surgery Technique
Fortunately, advances in cataract surgery over the last few years have made eye surgery safer, easier and more beneficial than ever before. There are several techniques that are used to perform cataract surgery, and Drs. Brian Stahl & James Knowles are some of the region’s most experienced cataract surgeons. Here at Stahl Vision and Eye Laser and Surgery Center we use the latest in technology both for measuring you for your implant lens, as well as for removing your cataract. It is this attention to fine details and advanced procedures that has our patients seeing so well! Advanced cataract surgery allows us to correct your nearsightedness, farsightedness, and even astigmatism at the time of your cataract surgery. With Advanced Lifestyle or bifocal implants we can have you reading again without glasses! Not all doctors or facilities do cataract surgery the same. With the advanced procedures and techniques that Dr. Brian Stahl and Dr. James Knowles employ, you will be back on your feet and recovering in a day or two. No stitches, no shots, small incision, with a quick return to activities with improved vision!
Not all doctors or cataract surgery is the same, do your homework and choose a surgeon offering the latest advancements, best results, and most experience.
Choosing Your Implant for Cataract Surgery
The best way to determine which implant lens or intraocular lens you should choose is by coming in for a complete eye exam. Once our doctors have measured and examined your eyes, we can discuss your lifestyle and near vision needs and discuss the options: a Standard Monofocal implant lens, an Advanced Lifestyle Bifocal implant lens for better near vision, or a Toric implant lens to see distance more clearly without glasses. All of these choices have been approved by the FDA after years of testing, and have been used for many, many years. How you see for distance and near vision after your surgery depends on the implant lens you choose for your surgery.
During cataract surgery or refractive lens exchange, the lens of your eye which has become cloudy over time will be replaced with an artificial intra-ocular lens (IOL). Traditionally this has been done with a standard or monofocal implant lens which is covered by your insurance. An Monofocal Aspheric Lens Implant is a type of monofocal implant that is specifically designed to reduce the visual disturbances caused by the optical aberrations found in ordinary lenses, helping patients achieve the clearest possible vision in certain lighting conditions. Patients who wish to have the best quality of distance vision, especially in dim or dusky conditions, may wish to consider an monofocal aspheric implant lens, but will still need to wear glasses for the very best distance and near vision. It will still be necessary to wear reading glasses or bifocals to correct your intermediate and near vision. Aspheric monofocal lens implants usually cost slightly more than a basic lens implant, but here at Stahl Vision we do not charge patients anything extra and all the implants we use are Aspheric.
Some patients have a lot of astigmatism, its something they have had their whole life. It may have made it difficult to wear contact lenses, and difficult to correct fully with glasses. Astigmatism is where the shape of the eye is not completely round, and shaped more like an American football. Unless astigmatism is corrected, it makes it difficult to see at distance and near both! Fortunately, now we can correct your astigmatism with a Toric lens, or an astigmatism correcting implant lens. The result is less dependence on glasses. Unless you choose a toric Crystalens (called a Trulign), you will still need reading glasses with a toric implant lens. You will, however; be able to wear the inexpensive “readers” that are readily available once your astigmatism is corrected. Strengths: shaper distance vision, can use inexpensive readers. Weaknesses: unless using a toric Crystalens (Trulign), you will need readers for up
The Crystalens® moves and flexes within the eye allowing it to change power or accommodate. This lens allows clear vision at distance and intermediate, but reading the smallest print or trying to see very close, closer than 17 inches, may still require reading glasses. The Crystalens works different than other implants like the Multifocal Tecnis or the ReSTOR and has the advantage of less night glare, and sharper contrast. The Crystalens can also correct for astigmatism, and this is a strong advantage for patients who have astigmatism, and may help them see better at distance. The Crystalens that fixes astigmatism is a toric lens, and is called a Trulign.
The Tecnis® Multifocal and Symfony (pronounced "symphony") Implant Lenses work by splitting the light reaching the eye into two focal points, providing good vision at near and far. The Tecnis Multifocal uses diffractive optics spread over the entire lens surface, and works well in dim and bright light conditions. While the optical qualities of these lens allows patients to see distance and near, some intermediate distances may be a little out of focus. Along with the ReSTOR, this lens has some night glare and halos around lights. This night glare is very noticeable at first, but improves over time. Tecnis Multifocal lenses come in several strengths that allows your doctor to customize your vision to the distance you are most comfortable reading. The Symfony implant lens (said symphony implant lens) is an improved design of the Tecnis multifocal lens with somewhat improved intermediate vision. The Symfony lens is the first FDA approved multifocal lens that can correct for astigmatism as well! Now more patients are candidates for bifocal implant lenses, especially if they have astigmatism.
Like Tecnis® Multifocal Lens, the Acrysof ReSTOR lens works by slitting the light reaching the eye into two focal points, providing good vision at near and far. The ReSTOR lens uses diffractive optics concentrated over the center of the lens surface, and works best in brighter light conditions. While the optical qualities of these lenses allows patients to see distance and near, some intermediate distances may be a little out of focus. Along with the Multifocal Tecnis, this lens has some night glare and halos around lights. This night glare is very noticeable at first, but improves over time. ReSTOR lenses come in several strengths come in several strengths that allows your doctor to customize your vision to the distance you are most comfortable reading.
As with any surgical procedure, there are always risks as well as benefits. During your visit to Stahl Vision we will perform a thorough cataract eye examination and then arrange scheduling for your implant lens measurements, your history and physical, and for your cataract surgery. In addition, we will then spend the time necessary to review the everyday activities that are most important to you-and whether being independent of glasses for those activities is something that you would like to achieve. As you prepare for your visit to Stahl Vision it will be helpful if you begin thinking about what those activities are so that you can discuss them and explore them with the staff.
