At Eye Care Specialists, we offer a variety of premium intraocular lens (IOL) implants. Commonly referred to as lifestyle lens implants, these IOLs have helped us restore clear, sharp vision for many cataract surgery patients in the Northeastern Pennsylvania area.
A variety of lens implant options are available as a refractive surgery option for patients who are not ideal candidates for LASIK. Click on the links below to learn more about these great LASIK alternatives:
AcrySof® ReSTOR® IOL
Until recently, life without reading glasses or bifocals was not an option for most cataract patients. You now have an option. The AcrySof® ReSTOR® intraocular lens (IOL), which is an artificial lens that is implanted in the eye to replace the eye’s clouded crystalline lens during cataract surgery, is a unique technological innovation that can provide you with quality vision throughout the entire visual spectrum – near through distance – with increased independence from reading glasses or bifocals.
The AcrySof® ReSTOR® IOL is now available and delivers a high level of glasses-free vision for cataract patients.
In the clinical study, 80% of patients receiving the AcrySof® ReSTOR® IOL reported that they never wear glasses for any activities. With the AcrySof® ReSTOR®IOL they can read a book, work on the computer, and drive a car – day or night – and play golf or tennis with an increased freedom from glasses. In fact, patients were so pleased with their vision, nearly 94% of patients said they would have the AcrySof® ReSTOR® IOL implanted again, if given the choice.
Eye Care Specialists and Dr. Harvey Reiser were selected as one of only 16 surgeons an sites in the United States to participate in the clinical research leading to the FDA Approval of the AcrySof® ReSTOR® IOL. Eye Care Specialists is one of the leading ophthalmology practices on the East Coast implanting the AcrySof® ReSTOR® IOL .
How Does the AcrySof ReSTOR IOL Work?
As we perform daily activities such as reading, watching television or working at the computer, our eyes are constantly focusing on objects at varying distances – up close, far away and everything in-between. The ability to quickly change focus throughout this range of vision is called accommodation. Accommodation is the ability of the eye’s lens to change shape to focus on objects at various distances. Unfortunately, this ability diminishes as we grow older, causing us to become dependent on bifocals or reading glasses. However, the AcrySof® ReSTOR® IOL was designed to provide quality near to distance vision by combining the strengths of apodized diffractive and refractive technologies. Similar technology has been used for years in microscopes and telescopes to improve image quality, and has now been patented for use in intraocular lenses by Alcon.
Apodization is the gradual tapering of the diffractive steps from the center to the outside edge of a lens to create a smooth transition of light between the distance, intermediate and near focal points. Diffraction involves the bending or spreading of light to multiple focal points as it passes through the lens. On the AcrySof® ReSTOR® IOL, the center of the lens surface consists of an apodized diffractive optic. This means that the series of tiny steps in that center area work together to focus light for near through distance vision. (Distance vision: Refers to focal points that are typically 7 feet or further from your eyes. Items that typically fall within the distance range of vision are billboards, street signs, and movie screens).
Refraction involves the redirection of light passing through the lens, to focus on the retina. The refractive region of the AcrySof® ReSTOR® IOL bends light as it passes through the lens to a focal point on the retina. This outer ring of the AcrySof® ReSTOR® IOL surrounds the apodized diffractive region and is dedicated to focusing light for distance vision.
During the AcrySof® ReSTOR® IOL clinical studies, patients experienced lifestyle enhancement through quality vision, and greater freedom from reading glasses and bifocals. In fact, according to the AcrySof® ReSTOR® clinical studies, four out of five patients with the AcrySof® ReSTOR® IOL reported never wearing glasses following cataract surgery in both eyes, compared to only 1 out of 10 patients with monofocal lenses. This is the highest level of freedom from glasses ever demonstrated in an IOL clinical trial.
Additionally, the AcrySof® ReSTOR® clinical studies indicated that nearly 94% of the study subjects were so satisfied with their new quality vision that they would have the AcrySof® ReSTOR® IOL implanted again.
ReZoom™ intraocular lens is a second-generation refractive multifocal IOL that provides hyperopic cataract patients with greater independence from glasses than monofocal IOLs. The ReZoom™ proprietary multifocal design provides a range of vision that monofocals cannot match.
The ReZoom™ Balanced View Optics™ technology distributes light over five optic zones so that each lens has a distance-dominant central zone for distance vision in bright light conditions when the pupil is constricted.
Clinical studies show that 92% of those receiving the ReZoom lens “never” or “only occasionally” need to wear glasses after their surgery.
Unlike conventional single-vision (monofocal) lens implants, state-of-the-art ReZoom™ lenses have been specially designed with multifocal zones that provide good vision across the spectrum of varying distances and light conditions. So you can see well anywhere and anytime, be it near, far or in between. Patients no longer have to settle for monofocal lenses that only provide good distance vision with limited ability to see objects that are near without glasses.
The ReZoom™ multifocal lens is a clear, foldable implant made of a high-refractive-index acrylic material. This new technology multifocal lens is designed to provide a full range of vision – near, distance and intermediate – after cataract treatment.
Is the ReZoom Multifocal Lens Right for Me?
If you are diagnosed with cataracts and are experiencing one or more of the following cataract symptoms, you may be a candidate for the ReZoom™ multifocal lens:
Difficulty seeing close objects
Difficulty seeing to drive, especially at night
Changing glasses prescriptions
Astigmatism occurs when the cornea is curved unevenly. Often there is more curvature in one direction than in the other. With astigmatism, light rays that normally focus in one point on the retina (light-sensitive tissue at the back of the eye) have no single point of focus. This causes images to appear blurry and distorted.
Astigmatic keratotomy (AK) and limbal relaxing incision (LRI) are the procedures that treat astigmatism. Our surgeons make a microscopic incision over the corneal surface. These incisions are made in the steepest part of the cornea, allowing it to relax and become more round. AK and LRI are often performed in combination with other refractive procedures and cataract surgery because astigmatism frequently accompanies nearsightedness or farsightedness. If you have significant astigmatism, your vision is somewhat blurry all the time.
AK or LRI combined with cataract surgery can improve your chances of excellent uncorrected postoperative vision. Patients with more than a diopter of topographical astigmatism should be considered for AK or LRI at the time of their cataract surgery. Use of AK or LRI becomes more important when using multifocal intraocular lenses (IOLs) because good simultaneous uncorrected distance and near vision can be obtained only with a nearly spherical cornea.
Toric IOLs for Astigmatism
Toric IOLs are designed to correct astigmatism. This provides another new option for cataract surgery patients. The ACRYSOF® Toric IOLs are artificial lenses implanted in the eye to restore vision after a clouded natural lens (cataract) is removed. The unique design of the AcrySof® Toric IOL makes it possible to reduce or eliminate corneal astigmatism and significantly improve uncorrected distance vision.
The lens of the IOL is convex on both sides (biconvex) and made of a soft plastic that can be folded prior to insertion, allowing placement through an incision smaller than the optic diameter of the lens. After surgical insertion into the eye, the lens gently unfolds to restore vision. The supporting arms (haptics) provide for proper positioning of the IOL within the eye.
Most surgeons who treat astigmatism in their cataract surgery patients tend to use astigmatic keratotomy (AK) pr limbal relaxing incisions (LRI) which involves making incisions in the cornea.
The ACRYSOF® Toric IOLs can also be used in adult patients with corneal astigmatism during cataract removal. The ACRYSOF Toric IOLs have been shown in a clinical study to provide good uncorrected distance vision in patients who have undergone cataract surgery and required reduction of corneal astigmatism.
