Cataracts are the most common cause of impaired vision. They cloud the normally clear lens of the eye, causing images to blur – much as they would be seen through a dirty camera lens. No one is sure what causes cataracts, but risk factors may include aging, family history, eye injuries, certain diseases and some medications.
What are the symptoms?
Cataract symptoms include:
- Hazy or blurred vision.
- Steady deterioration of vision leading to more-frequent changes in your eyeglass prescription.
- Halos and glare appearing around lights at night; difficulty driving at night.
- Colors appearing less vivid than usual Depending on a cataract’s density, vision loss can range from slight to complete.
None of these symptoms is “proof” of a cataract. A thorough examination by our staff of ophthalmologists and optometrists can determine whether cataracts are present.
How Are Cataracts Treated?
There are no medicines, vitamins, diets or lifestyle changes known to either prevent or correct cataracts. Cataracts are correctable only through surgery; typically, the procedure is both routine and highly effective. You can learn more about cataracts here.
Cataract surgery is considered by many a modern-day miracle. It is fast, simple, minimally invasive and typically creates dramatic improvement in vision. The procedure is routinely performed on an outpatient basis.
Grossnickle surgeons perform “no-stitch” cataract surgery. You will receive mild sedation and topical anesthetic drops. Working under a microscope, the surgeon will make a very small incision through which the cataract will be removed and an interocular lens implanted. The entire procedure takes less than 15 minutes. You will be awake throughout, and experience little or no discomfort. After surgery, you’ll receive complete instructions from the nursing staff. You will be examined the following day, and may then resume normal activity, generally without restriction. Follow up appointments with your optometrist, for further examination and new glasses, may be scheduled as appropriate.
The ReSTOR® lens represents a significant advancement over traditional lenses. By incorporating a highly advanced, proprietary technology calledapodization, the AcrySof® ReSTOR® lens offers patients a full range of vision resulting in the highest level of spectacle freedom demonstrated in clinical trials.
The AcrySof® ReSTOR® apodized diffractive lens structure is made up of a series of concentric steps formed in a circular pattern. A gradual decrease in step heights creates a smooth transition of light between the distant, intermediate and near focal points. This design improves image quality while minimizing visual disturbances.
As light passes thru the lens, these concentric steps create light waves that form distinct images as they intersect at different focal points. These multiple points of focus enable the patient to achieve a quality range of vision near thru distance.
The AcrySof® ReSTOR® lens can therefore provide lifestyle vision for a majority of active patients who desire to reduce their dependency on glasses. Clinical studies show 80% of patients never needed to wear glasses for any activity. Results based upon quality of life questionnaires demonstrate that patients have the vision needed for daily tasks such as applying make-up, shaving, reading a car dashboard or viewing a computer screen without glasses.
AcrySof® ReSTOR® is also used in refractive lens exchange for those patients with nearsightedness and presbyopia (the need for reading glasses) who do not have a cataract but would like good vision at distance and close without dependence on glasses.
Crystalens™, is an accommodating implantable lens that allows patients to focus automatically and seamlessly at all distances. A revolutionary new breakthrough in vision enhancement, it is an implantable lens replacement that accommodates like the eye’s natural lens, allowing for seamless focusing up close, far away and at all distances in between, giving patients their best possible vision.
The ability to provide patients with clear vision at all distances is a significant technological breakthrough. Unlike standard lenses used for cataract surgery, the Crystalens™ restores vision at all distances and in many cases eliminates the need for glasses and contacts for everyday tasks.
The Crystalens™ is the result of more than 14 years of research and development. Early in its research, it was noted that the ciliary muscle in the eye did not stop functioning as patients got older. This muscle inside the eye is responsible for focusing the eye in younger patients. Therefore a lens was created that works by moving in a backwards and forwards motion in response to pressure changes in the front and back of the eye that result from relaxation and contraction of the ciliary muscle. As a result, patients experience the vision they had when they were younger, for most without the hassles of corrective lenses.
In contrast, standard implantable lenses restore only distance vision – therefore patients may still require glasses or contacts to see up close and all points in between. Most people don’t realize how much vision occurs at arm’s length and at in between distances. In between vision means you can sit at your computer, read a magazine or engage in a hobby, even use a golf scorecard, in most cases without corrective lenses.
Crystalens™ is also used in refractive lens exchange for those patients with farsightedness, nearsightedness and presbyopia (the need for reading glasses) who do not have a cataract but would like good vision at distance and close without dependence on glasses.
