What is a Cataract?
Cataracts happen when the natural lens of the eye is clouded. Cataracts have a gradual process that can cause loss of visibility and may eventually cause blindness if the patient goes without treatment. Most cataracts are a product of genetics or age, but there are other types as follows:
· Traumatic cataracts that result from injury to the eye
· Radiation cataracts that result of radiation exposure
· Secondary cataracts from complications of glaucoma, diabetes, or certain medications
Age-related cataracts generally become noticeable sometimes after age 55. Signs of cataracts include:
· Increasing glare
· Poor night vision
· Cloudy or burry vision
· Faded colors, often described as dull or flat vision
· Double vision with only one eye open
· A sudden change in your classes prescription
· Light sensitivity
Cataract surgery is necessary to remove the cloudy lens, which is then replaced by an artificial lens called an intraocular lens (IOL). Until recently all IOL’s were fixed for one distance; requiring most patients to need glasses after cataract surgery. Today, there are many different lens options available and depending on your individual needs and lifestyle, Dr. Alward will help you decide which lens best suits you.
Lens Replacement Options for Cataract Surgery
Dr. Alward is recognized nationally as a leader in cataract surgery and lens replacement, specializing in advanced lens replacement procedures. At the time of catract surgery, you can choose to have your natural lens replaced with either a traditional single focus lens (IOL) or an advanced Lifestyle IOL option.
The new lens implants provide a fuller range of vision, improving your vision at near, intermediate and distance most like the lenses you were born with. Most patients who choose these lenses do so because they prefer a fuller range of vision without glasses the majority of their day.
Choosing the Right Lens Implant
Until recently, cataract patients had virtually no choice in the lens implants used to restore vision. With new Lifestyle lenses, you now have several choices based on your individual visual needs and lifestyle.
· Standard IOL: Good for distance only. You will still need to wear glasses for up-close visual.
· AcrySof ReSTOR: Multifocal lens provides good vision at all distances. Alcon’s patented technology combines the strengths of apodized diffractive and refractive technologies, which are similar to the technologies used in microscopes and telescopes, allowing for good vision at a wide range of distances.
