The Cataract Surgeons
Improving your vision with Lens Implants through cataract surgery can be a multi-step process that requires input from you and your eye doctor. Selecting the best intraocular lens, or IOL, to replace your natural lens is one crucial part of cataract treatment. With the right IOL, not only will you have a clearer vision, you can correct lifelong eye problems such as near- or farsightedness and enjoy close to 20/20 vision. In some cases, however, eyeglasses may be needed after surgery to fine-tune distance and/or reading vision.
Multifocal Lens Implants
Multifocal IOL lens implants enable patients to see near, far and intermediate distances after surgery. 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 fewer artifacts or distortion in either of the images, providing good quality of vision at both distance and near.
Accommodating lens implants have garnered a significant amount of positive reviews and testimonials from thousands of early patient adopters. These special lenses are designed to mimic or accommodate, just like the eyes natural lens would. The hinge design of the lens enables it to move inside the eye just like the original natural lens. The end result is that patients can see better at multiple distances. The only accommodating IOL available is known as the Crystalens® by Bausch & Lomb.
Toric lens implants are a unique type of lens implant that is used to correct astigmatism. A Toric lens implant is NOT the only method of astigmatism correction, so consult a doctor about the current possibilities. The 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.
Premium lens implants can be very exciting for patients that want to have a new level of spectacle freedom after cataract surgery, or with clear lens extraction. Due to the complex nature of each person’s visual system, it is difficult for a patient to make an assessment of the right lens without consulting a medical ophthalmologist.
