    Presbyopia 101

    Last updated 1 year ago

    When most people think of refractive errors, their first thought is of nearsightedness, farsightedness, or astigmatism. But there is another form of refractive error that few people are familiar with—presbyopia. Presbyopia occurs when the lens within the eye loses its flexibility and can no longer focus clearly on nearby objects, and often develops during the early to mid-40s.

    While the symptoms of presbyopia may seem to occur suddenly, the loss of flexibility of the lens takes place over several years. Individuals with presbyopia may experience a number of symptoms, such as holding reading materials at arm’s length, blurred vision at normal reading distance, eye fatigue, eye strain, and headaches.

    If you are suffering from presbyopia, your ophthalmologist may be able to prescribe you with reading glasses, contact lenses, bifocals, or trifocals. Learn more about the treatment options for presbyopia by calling the ophthalmologists with Ophthalmic Consultants of Chicago at (847) 388-0309.

    A Look at the Different Types of Cataracts

    Last updated 1 year ago

    A cataract is the clouding of the lens within the eye responsible for reflecting light onto the retina, resulting in blurred or cloudy vision. While your ophthalmologist can determine if you are a good candidate for cataract surgery, it is important to first educate yourself on the different types of cataracts.

    Nuclear Sclerotic

    Cataracts are typically the result of age, injury, or genetic predisposition. However, most cataracts are the result of the aging process. The most common age-related cataract is a nuclear sclerotic cataract, in which the central portion of the lens known as the nucleus becomes hardened and yellows over time, in what is known as sclerosis. As the cataract grows in size, it interferes with the eye’s ability to focus properly, while close-up vision may temporarily improve.


    Another common age-related form of cataracts is a cortical cataract, in which white cloudy areas form on the cortex of the lens located on the peripheral or outside edge. This is often the result of changes in the water content of the lens fibers, which allow for the development of fissures that look like spokes leading from the outside edge of the lens towards the center. As light enters the eye, it scatters across these fissures and can lead to blurred vision, contrast changes, glare, and changes to depth perception.

    Posterior Subcapsular

    Posterior subcapsular cataracts are similar to cortical cataracts, except that the opaque or cloudy areas form on the posterior or back surface of the lens rather than the edge. Individuals with this type of cataract often struggle with reading and experience “halos” or glare around lights.

    What to Expect Before, During, and After LASIK Surgery

    Last updated 1 year ago

    In previous years, individuals suffering from refractive errors were forced to rely on prescription glasses and contact lenses to correct their vision—but thanks to LASIK eye surgery, those with hyperopia, myopia, and astigmatism can now improve their vision without the need for corrective lenses. Make sure you know what to expect before, during, and after undergoing LASIK surgery with your ophthalmologist by reading over this article.

    Before Surgery

    As with any medical procedure, you will first be required to meet with your ophthalmologist for an initial consultation before undergoing LASIK surgery. During this time, you will complete a patient medical history questionnaire outlining your family’s history of disease, personal history of illness, previous surgeries, symptoms, current medications, and lifestyle factors. Once this is complete, your eye doctor will perform a comprehensive eye examination before determining your candidacy for the procedure.

    During the Procedure

    After administering anesthetic drops into your eyes, your ophthalmologist will use an automated instrument known as a microkeratome to create a thin flap of tissue along the top layer of your cornea. This flap is then lifted back in order to reveal the middle layers of the cornea before they are reshaped using an excimer laser.  The flap is then placed back into position where it heals without the need for stitches.

    After Surgery

    By correcting the curvature of the lens, LASIK surgery effectively allows light to focus properly on the retina for clearer, sharper vision. While some individuals may experience light sensitivity for a few days, most patients experience improved vision immediately following the procedure and are able to return to work the day following the procedure.

    Examining the Function of Your Eyes

    Last updated 1 year ago

    Protecting your vision is imperative to your overall health and wellbeing. But to do so, it is important that you understand how your eyes work. For example, did you know that light comes in through your cornea, or the clear tissue that covers the front of your eye? The pupil, or the dark spot in the middle of your eye, controls the amount of light that enters your eye. When it’s dark, the pupil widens to allow more light in and when it is bright, the pupil narrows to limit the amount of light entering the eye.

    While vision changes are often normal, in some cases vision loss can be a symptom of a larger problem. As such, it is essential that you schedule an eye appointment with your ophthalmologist whenever you experience noticeable vision changes. Call (847) 388-0309 to schedule an appointment with Ophthalmic Consultants of Chicago today.

    Symptoms of Dry Eyes

    Last updated 1 year ago

    Dry eyes can range in severity from a minor inconvenience to a serious vision problem. Symptoms of dry eyes can include a stinging, burning, or scratchy sensation in your eyes. Patients with dry eyes may have increased eye irritation from smoke or wind, sensitivity to light, and excessive tearing. In addition, they may realize that they are suffering from eye fatigue or eye redness. Blurred vision or trouble focusing, particularly at the end of a long day, can also be a symptom of dry eyes.

    If you are experiencing symptoms of dry eyes, schedule an appointment with your ophthalmologist.
