Photorefractive Keratectomy (PRK)
A refractive surgical procedure that employs a computer controlled excimer laser system to sculpt, by ablation of the central corneal zone, or visual axis. This procedure corrects mild to moderate cases of nearsightedness. Patients who are not candidates for LASIK may be candidates for PRK as less corneal tissue is removed during the treatment. With PRK, the visual recovery is slower and there may be more (initial) post-operative discomfort than that of LASIK. Also, the incidence of post-operative ocular dryness is reduced with PRK, making this an excellent procedure for those patients who suffer from dry eye syndrome.
Custom Photorefractive Keratectomy (PRK)
Custom PRK is a procedure that enables your laser vision correction surgeon to further customize the conventional PRK procedure to your individual eyes. Custom PRK provides an additional level of data about your vision requirements using wavefront technology. A device called a wavefront analyzer measures the way light travels through your eye and compares it to an eye with perfect vision. This device then creates a 3-D wavefront map that is uniquely yours, in the same way that your “fingerprint” is unique to only you. This additional data is then used by your surgeon to customize the PRK laser vision correction procedure to your individual vision requirements.
The actual PRK procedure process is performed the same way in both conventional PRK and Custom PRK. Conventional PRK is an excellent choice for many patients.
Your doctor will recommend which procedure is best for you based on your visual requirement; they will help you to determine if you could benefit from the higher level of customization that Custom PRK may provide.
Refractive Lensectomy (RL/IOL)
A refractive surgical procedure that is commonly used to treat patients with cataracts. The procedure has been modified to also correct nearsightedness in high prescription ranges and most ranges of farsightedness. During the lensectomy procedure, the natural lens (crystalline lens) is extracted and an artificial lens is implanted. The power of the artificial lens is determined preoperatively during the full eye examination. There is minimal discomfort and visual recovery is very rapid.
Presbyopia Correcting Lenses
Presbyopia is the age-related loss of the ability to focus up close to read. New implants developed for use after cataract surgery can to a large extent reverse these changes and allow independence from glasses after surgery. Three of these implants (IOLS) are now approved by the FDA.
Vivity Intraocular Lens
Laurel Eye Clinic is now offering the Vivity lens to our cataract patients. The Vivity lens uses proprietary technology called X-Wave which uses all available light around it to provide patients with an extended and continuous range of vision.
How does the Vivity lens work?
Thanks to X-Wave technology, the Vivity lens gives you sight without boundaries. Whether you’re looking at something up-close, far away, or in between, you’ll be able to see clearly. The Vivity lens also offers protection from the sun’s damaging UV rays and can even filter blue light rays. An advantage of the Vivity IOL is that patients that chose it are already reporting fewer visual aberrations.
This includes things like starbursts, glare, and halos around lights. If you want to drive at night after cataract surgery, this is something that sets the Vivity lens apart from other intraocular lenses.
Will I still need to wear glasses if I choose the Vivity lens?
Many patients with the Vivity lens reduce their dependence on glasses or contacts after cataract surgery. You may find that it’s easier to complete tasks like texting on your phone or reading labels while grocery shopping without glasses.
The Vivity lens provides patients with excellent visual acuity, meaning sharper vision. Even in bright and dim lighting at intermediate and far distances, your vision will still be sharp and clear. Like working in front of the computer? The Vivity IOL is great for completing this kind of work as well!
Can I get the Vivity lens if I have astigmatism?
Yes. The Vivity lens is also available in a toric model. If you have astigmatism, the toric model will correct your astigmatism and other refractive errors during cataract surgery. Want to find out if the Vivity lens could be right for you? The only way to know for sure is to schedule a cataract screening at Laurel Eye Clinic now!
PanOptix Trifocal IOL
How Is The PanOptix Trifocal IOL Different Than Other IOLs?
When you undergo cataract surgery, the natural lens is removed and replaced with an artificial lens, or IOL. The traditional IOL used during cataract surgery is called a monofocal lens.
This is a lens that has one uniform refractive power with a single, fixed focus. With a monofocal lens, wearers will still need to use glasses to see.
Premium lenses are an optional upgrade that can provide even sharper vision. Multifocal IOLs provide the wearer with alternating rings of two different refractive powers.
One refractive power is for seeing at a distance, and one refractive power is for seeing up close. This allows the wearer to see at a distance and sharply up close. This eliminates the need for reading glasses.
But the trifocal IOL is different. It doesn’t only allow the wearer to see well up close and far away. It allows them to see clearly at a middle, intermediate distance as well, providing better image quality at all distances.
The PanOptix trifocal IOL provides crystal clear vision at all distances, and in any lighting situation. Other premium IOLs may reduce dependency on reading glasses, but the PanOptix trifocal lens can make a life without glasses possible!
How? In a clinical study, 129 patients with the PanOptix lens were asked about their experience with it. Of those 129 patients, 80.5% reported that, within the past week, they never had to wear glasses to see.
How Does The Trifocal IOL Work?
A trifocal IOL works in a similar manner to a multifocal lens. The lens is composed of alternating rings expanding from the center of the lens.
The difference is that with a trifocal, there are three sets of refractive powers for the rings. One is for near vision, one is for distance vision, and one is for intermediate vision.
The alternating rings train the eye to look through the appropriate ring depending on what the wearer is focusing on. If you focus on something up close, your eye will adjust to see through the ring set to near vision.
The process is seamless and almost instantaneous. There are also several benefits unique to trifocal users, especially those with the PanOptix trifocal lens.
Why Choose The PanOptix Trifocal IOL?
Alcon’s PanOptix trifocal lens is the best lens of its kind, for several reasons. The PanOptix lens is made of a hydrophobic material, meaning it won’t absorb moisture from the eye.
Because the PanOptix trifocal lens is made of a hydrophobic material, this reduces the risk of dry eye. The material also filters out ultraviolet rays and blue light.
This protects your eyes from sunlight and harmful light from electronic screens. For an increasingly digital world, this is an important feature!
The image quality of the PanOptix trifocal is also better than other brands. Other brands tend to give the wearer very sharp middle vision but not-so-sharp close-up vision.
But the PanOptix lens has a focal point of 60cm. This helps the wearer see clearly both up close and at a middle distance. Many PanOptix users don’t even need to wear reading glasses.
With the PanOptix trifocal IOL, you can finally experience vision as it’s meant to be:
• There are no blurry zones so you can see without ever having to strain to focus
• See colors brighter and more vividly
• The PanOptix trifocal lens corrects and sharpens vision, making you less likely to wear glasses
• Experience less glare around bright lights
Who Is the PanOptix Trifocal IOL Best For?
The PanOptix trifocal lens works for many patients. But not every IOL is best for everyone. The only way to know if you’re a good candidate for the PanOptix trifocal IOL is to have a cataract screening at Laurel Eye Clinic.
The trifocal lens offers sharper focus at a greater range of distances than many other IOLs. But it is a premium IOL, which means it does cost some money out-of-pocket.
The standard monofocal lens is usually covered by insurance along with surgery. The monofocal IOL can also be used to create something called monovision.
Monovision occurs when a monofocal lens is placed in either eye, one set to see near and the other for distance vision. It gives the user acceptable intermediate vision but sacrifices how sharp and in focus details look at any distance.
Monovision is often recommended for patients who spend a lot of time on screens since monofocal users see best at a middle distance.
But the PanOptix trifocal IOL is even better for patients who spend a lot of time on screens. This includes working on a computer, reading a menu, and seeing a mirror. What makes the PanOptix trifocal lens so revolutionary is the fact that patients have a full range of vision!
Patients with the PanOptix trifocal IOL have clear, complete vision for all sorts of activities, like:
Seeing Far Away
• Seeing a friend’s familiar face across a crowded room
• Going to see a show or concert
• Driving a car to run errands
• Watching TV on a lazy Sunday
Seeing At Arm’s Length
• Using a computer for work or at home
• Reading a menu at a favorite restaurant
• Seeing the mirror to put on makeup
Seeing Up Close
• Reading a book on a cold winter evening
• Knitting a blanket for a grandchild
• Using a smartphone to send an email
Not only does the PanOptix trifocal lens protect against blue light from screens, but the sharpness of objects viewed at an intermediate distance is even better than it is for standard monofocal users.
This is game-changing for IOLs since before the trifocal lens, screen users had to settle for monofocal IOLs. Why wouldn’t you want an IOL that provides you with fantastic vision if you’re looking at a screen or reading a book?
