Cataracts are a universal aging change of the natural lens in the eye. The lens of a normal eye is clear when we are born, but as we age, most of us have at least a slight clouding of the lens. We look through the lens to see (it focuses light rays on the retina inside the eye, much like the lens in a camera focuses light on the film), so clouding of the lens makes it harder to see clearly. If there is only mild clouding of the lens, or very mild cataract, the vision may not be affected enough to warrant treatment.

As cataracts progress and get denser, vision becomes more affected. This is generally a gradual visual change. A sudden change in vision is NOT typical of a cataract.

Cataract Symptoms

Patients with mild cataracts may not have any symptoms. As cataracts progress, patients may notice one or more of the following symptoms:

  • Dimmer or darker vision
  • Blurred or hazy vision
  • Double vision
  • Poor vision in bright light
  • Seeing halos around lights
  • Poor vision at night
  • Difficulty driving at night
  • Yellowish tinged vision
  • Needing more light to read
  • Frequent changes in eyeglasses or contact lens prescription

Cataract Treatment

Treatment for cataract-related vision changes begins with a thorough eye exam, including dilation of the pupil to make sure that there are no other eye problems causing loss of vision. Once the ophthalmologist concludes that the cataract is the source of the visual complaints, there are several options. Often a glasses or a contact lens prescription update will improve the vision enough that the patient sees well and is content with his/her vision.

About the Cataract Procedure

Dr. Wyse performs cataract surgery at Glenbrook Hospital in Glenview and at NorthShore Surgicenter in Lincolnwood. The procedure itself typically takes 10 to 15 minutes, and patients are usually at the hospital or surgicenter for about 3 hours. Patients are given sedation and topical drops (no shots) to make the procedure very comfortable. Patients who are anxious can receive extra sedation so that they essentially sleep through the procedure. Afterwards, patients can usually resume most of their regular activities and return to work within 1 to 2 days.

Our doctors perform state-of-the-art, cataract surgery using the most advanced equipment and techniques. This minimally invasive, small-incision, no-stitch cataract procedure is called “clear cornea phaco-emulsification under topical anesthesia.” This technique allows for rapid recovery after the procedure with very little downtime.

We also offer bladeless laser cataract surgery using the LenSx femtosecond laser, the latest and most advanced method of cataract removal.  This laser procedure includes real-time imaging of the eye during surgery to allow for unsurpassed precision and customization in cataract surgery.

Surgery involves removal of the natural lens of the eye, which has become cloudy over time, and replacement of the lens with a clear lens implant (most commonly made of acrylic). A microscopic incision is made in the cornea, and ultrasound or laser is used to break up the lens into small fragments. The lens fragments are then removed, leaving the capsule that surrounds the natural lens in place to hold the new artificial lens (the intraocular lens implant or IOL). This is all done under topical anesthesia (meaning eye drops rather than shots), and with intravenous sedation to make it a very comfortable experience for the patient.

Standard Lens Implants

Traditionally, after the cataract is removed, the natural lens is replaced by a standard or single focus intraocular lens implant (standard IOL). This lens improves the patient’s DISTANCE VISION, but reading glasses or bifocals may still be required to view things closer than arms length. Alternatively, the patient may choose a single focus lens implant (standard IOL) that provides focus at NEAR VISION, and will therefore still require glasses to see distance.

Advanced Technology Lens Implants

One of the most exciting changes in cataract surgery in the last 10 years has been the introduction of a variety of special lenses called “Advanced Technology “ lens implants (also referred to as “Premium” lens implants). These lenses include the Alcon Toric lenses for astigmatism correction, Alcon ReSTOR® Multifocal Lenses, TECNIS® Multifocal, Symfony Extended Range, Symfony Toric Extended Range and Crystalens® accommodating lenses. These more advanced lenses are designed to allow patients to be more independent of glasses. Measurements of the eye using the most technologically advanced, state-of-the-art equipment are taken in the office to determine if one of these implants would be appropriate for the patient’s eye.

Based on these measurements and the wishes of the patient, we can identify the best lens choice for the individual. This is an interactive process between the patient, the doctor, and our staff, and we understand that patients may have many questions and need clarification. You will find that our staff is very knowledgeable and accessible, and willing to spend as much time as it takes to answer all of your questions.

After Cataract Removal

After the procedure, most patients can resume their normal activities within a day or so. Dr. Wyse is available by pager 24 hours a day should any concerns or questions arise. Patients are seen for follow up the day after and about a week after the procedure.
