    What Is Keratoconus?

    Last updated 8 months ago

    A normal, healthy cornea is shaped like a dome. If your eye doctor diagnoses you with keratoconus, it means that your cornea has developed an outward, cone-like bulge. Keratoconus is caused by the weakening of the protein fibers, or collagen, in the eye. When these fibers lose their strength, they can no longer hold the cornea in its proper shape. Keratoconus can become worse over time, or it may develop abruptly. Typically, one eye is affected first, and the other eye later develops it. Although more research is needed to determine the exact causes of keratoconus, it is believed that genetics plays a role.

    Keratoconus can significantly interfere with your eye’s ability to focus on objects. You’ll likely notice blurry vision, light streaking, and halos around lights, particularly at night. Many people with keratoconus also have trouble with glare at night. You’ll require eyeglasses or contact lenses to see properly. If you have a severe case of keratoconus, your ophthalmologist may recommend a corneal transplant.

    Qualities to Look for When Choosing an Ophthalmologist

    Last updated 8 months ago

    Ophthalmologists are medical doctors who have received specialized training in eye care. They are qualified to administer examinations, diagnostic procedures, and treatments, including eye surgeries. If you’re looking for a new ophthalmologist, or you’ve never seen one before, there are a few factors to consider. Use the points below to guide your decision when selecting an ophthalmologist.

    Qualifications

    Ophthalmologists must complete a minimum of eight years of medical training after college. Additionally, some choose subspecialties, such as pediatric care or glaucoma management. Ask the doctor what type of training he or she has received and whether he or she is board certified. Also, make a note of whether the doctor has received any awards or other achievements, and how much experience he or she has. Some ophthalmologists choose to participate in research, such as clinical trials, to contribute to medical advances.

    Availability

    With kids, work, and other obligations, you likely have a full schedule. When choosing a new ophthalmology practice, consider the availability of appointments. Depending on your schedule, you might prefer a practice that offers early morning or evening appointments, or perhaps same-day availability.

    Services

    Depending on your specific eye care concerns, you may wish to choose an ophthalmology practice that specializes in certain areas, such as Lasik surgery for vision correction or cornea transplants for diseased or damaged corneas. Ask the ophthalmologist about his or her practice’s range of services, specialties, and available technology.

    Patient Education

    A key component of any type of medical service is patient education. Choose an ophthalmologist who believes strongly in the value of educating patients about the basics of eye care and specific conditions.

    At Ophthalmic Consultants of Chicago, we pride ourselves on our wide range of services in our state-of-the-art facility and on the extensive qualifications of our providers. Please call us at (847) 388-0309 to schedule an appointment or ask any questions you may have. We offer same-day appointments whenever possible.

    Nearsightedness and Farsightedness

    Last updated 8 months ago

    Your eyes are complex organs. An eye works by passing light rays through the cornea, which is the clear lens on the front of your eye. Then, the light travels through the pupil and focuses on the retina. If you have myopia, or nearsightedness, the light doesn’t focus properly and you have trouble seeing objects far away. Farsightedness, or hyperopia, is just the opposite—far objects are clear while close objects are blurry.

    Learn more about how your eyes work by watching this animation. You’ll learn more about the parts of the eye and how the light rays are converted to create images.

    If you experience headaches or other symptoms of eyestrain, it’s time to schedule an exam with an ophthalmologist. Call Ophthalmic Consultants of Chicago at (847) 388-0309 or visit our website to view our ophthalmology services.

    Your Guide to the Different Types of Refractive Errors

    Last updated 9 months ago

    One of the conditions your Refra might diagnose you with is a refractive error. Refractive errors occur when there is a problem with light rays focusing on the retina, which is located at the back of the eye. Normally, light rays enter through the cornea, are transferred through the pupil, and are focused onto the retina by the lens. If you have a refractive error, your eye doctor will diagnose you with one of the following types:

    Myopia

    Myopia, commonly called nearsightedness, occurs when the eye is excessively long or has focusing difficulties. If your eye doctor tells you that you have myopia, it means objects in the distance are blurry. You’re able to focus better on close objects. This type of refractive error typically becomes progressively worse, particularly through the teen years and early 20s.

    Hyperopia

    If you can see objects in the distance more clearly than objects close to you, your doctor will diagnose you with hyperopia, or farsightedness. This refractive error occurs because the eye is too short or it does not have sufficient abilities to focus. Unlike myopia, hyperopia tends to worsen during early childhood, yet improve or stabilize during the teen years.

    Presbyopia

    Presbyopia is a form of farsightedness associated with changes of the aging process. The middle of the lens becomes harder than usual, which makes it challenging to see objects close to you. It is possible to have both nearsightedness and presbyopia. In fact, most people over the age of 50 are affected by presbyopia to some degree.

    Astigmatism

    Like presbyopia, it is possible for your eye doctor to diagnose you with a combination of astigmatism and another refractive error. Astigmatism is a condition in which the cornea curves abnormally in one direction, causing blurry vision.

    If you’ve noticed changes in your vision, schedule an appointment with an ophthalmologist promptly. Call Ophthalmic Consultants of Chicago at (847) 388-0309 for an appointment with one of our highly qualified eye doctors. Ask us about our Lasik surgery procedures to correct refractive errors.

    Cataracts and the Aging Eye

    Last updated 9 months ago

    It is normal for your visual acuity to decline as you grow older, as the natural lens within your eye becomes harder and yellows in what is known as a cataract.

    In this video, we take a closer look at how cataracts develop and affect the eyes. Cataracts are extremely common, and affect approximately 50 percent of all adults by the time they reach age 80.  Individuals who develop cataracts often struggle to see objects at close distance, experience halos or glare around lights, and suffer eye fatigue. Learn how you can protect your eyes and postpone the development of cataracts by watching this full clip.

    Don’t let cataracts interfere with your vision. Get the facts about cataract surgery and LASIK eye surgery by contacting Ophthalmic Consultants of Chicago at (847) 388-0309.
