Premium lens implants
Introduction to Premium Lens Implants
A new lifestyle alternative
If your doctor has told you that you are in the early stages of developing cataracts or has suggested that refractive lens exchange would be a good vision correction option, you might want to research the new emerging lens implant technology in the field of ophthalmology. If you are nearing the age for cataract surgery and want a reliable vision correction solution premium lens implants might be a good idea. Premium lens implants have been helping people over 40 and cataract aged patients have the active lifestyle they has when they were younger. Imagine playing golf or being able to read the newspaper with a dependency on glasses. Life without glasses could dramatically impact your overall happiness.
Emerging Lens Implant Technology
This intraocular lens technology of modern day ophthalmology has recently made some swift advancements that can dramatically improve a patient’s ability to see with lens implants after cataract surgery or even as refractive lens exchange before the development of cataracts. Some of these new intraocular lens implants might even be a better vision correction option than LASIK eye surgery depending on your prescription and age. In the past with LASIK eye surgery our doctors could correct myopia, hyperopia and astigmatism. Now with the advent of premium multifocal IOL lens implants the giant burden of presbyopia can now be corrected. Presbyopia affects a vast part of our aging population and often requires bifocal glasses. People in their mid forties that have trouble with reading and typically experiencing the first effects of presbyopia. Presbyopia is an accommodation problem with the lens of the eye. As the lens hardens and becomes inflexible with age it becomes more difficult to focus.
Main Types of Premium Lens Implants (ALSO called lifestyle lenses because there is potential for them to drastically reduce the need for eyeglasses after surgery.
Multifocal Lens Implants
Multifocal IOL lens implants enable patients to see at near far and intermediate distances after surgery. The 2 major brand names in this category are the The AcrySof® ReSTOR® IOL by Alcon and the Tecnis® by AMO. (Recently acquired by Abbott). 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 less artifacts or distortion in either of the images, providing good quality of vision at both distance and near.
Toric Lens Implants are a unique type of lens implant that are used to correct astigmatism. A toric lens implant is NOT the only method of astigmatism correction so consult a doctor about the current possibilities. 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.
Accommodating IOL – Crystalens®
How does the Crystalens® IOL work?
After the age of 40 people will often start to experience serious trouble reading as the eye’s natural lens starts to harden. Prior to the age of 40 it is not uncommon that many people often experience excellent vision and are typically confused as to what is happening with their eyes. Because their vision may have been perfect they have never consulted an ophthalmologist as to what is naturally occurring. This inability to see at close distances or difficulty for the muscles in the eye to auto-focus can be very discouraging. This is known as loss of accommodation, or presbyopia. The crystalens lens was researched and developed specifically to help correct the aging vision condition and was engineered with a hinge design that allows the optic to move as your focus on an image changes.
The crystalens® procedure is performed in a surgery center environment. After a small incision is made at the edge of the cornea, the natural lens is removed with phaecoemulsification and the crystalens® is implanted. crystalens® can usually be implanted in less than 15 minutes.
The recovery period is usually short. Most patients are able to pursue normal activities almost immediately after surgery. Discuss with your doctor beforehand what to expect before, during, and after the procedure as well as eye drops and postoperative office visits.
If you are like most patients who have the CRYSTALENS®, you can expect to enjoy the “luxury of sight” near, far, and everywhere in between and see everything more clearly. Your focus will be sharper than it has been in years, and you can expect to see improvements over time.
FDA Clinical Trial Information
- 98.4% of patients implanted with crystalens in both eyes could pass a driver’s test without glasses
- 100% could see intermediate (24″ to 30″) without glasses, the distance for most of life’s activities
- 98.4% could see well enough to read the newspaper and the phone book without glasses.
- Some patients did require glasses for some tasks after implantation of the crystalens
- Significantly more patients implanted with a crystalens (88.4%) could see better at all distances then patients implanted with a standard IOL (35.9%)
