    What Is LASIK Surgery?

    Last updated 7 months ago

    Laser-assisted in situ keratomileusis, better known as LASIK, is a popular surgical procedure for the correction of nearsightedness, farsightedness, and astigmatism. It’s estimated that more than 600,000 LASIK surgeries are performed each year in the U.S.

    To learn more about LASIK vision correction, including its benefits and risks, watch this informative video from the FDA. Most patients report being satisfied with the outcome of LASIK, but this procedure is not for everyone. If you have recent changes in your eyeglasses prescription, diabetes, a medical condition that inhibits healing, or a history of eye disease, injury, or surgery, you may not be an ideal candidate. Watch the full video for complete information about what to expect from LASIK.

    At Gerstein Eye Institute in Chicago, our eye surgeons are proud to offer the latest in laser vision correction technology to our patients, including custom LASIK with our state-of-the-art IntraLase FS laser and ALLEGRETTO WAVE® Eye-Q.

    Questions to Ask Your Doctor about Cataract Surgery

    Last updated 7 months ago

    Cataract surgery is one of the most common operations performed in the United States and is a safe, effective way to improve vision. If your eye doctor has diagnosed cataracts as the cause of your vision problems, you may be considering surgery. Here are some questions to ask your eye surgeon.

    Should I Have Cataract Surgery Right Away?

    Cataracts do not constitute a medical emergency. Although vision will progressively worsen if cataracts are left untreated, there is no distinct advantage to early intervention and no long-term damage will be caused if surgery is delayed. If cataracts are impairing your ability to drive, read, or perform other everyday activities, it may be time to seriously consider surgery.

    Which Type of Replacement Lens Is Best for Me?

    During surgery, the clouded lens of the eye will be removed. In most cases, the natural lens is replaced with an artificial intraocular lens (IOL) that is permanently implanted. An IOL can be monofocal or multifocal. Though multifocal lenses may eliminate the need for glasses in some cases, not every patient is an ideal candidate. Implanting multifocal IOLs is more complicated than the procedure for monofocal lenses and is not recommended for those with diabetic retinopathy, macular degeneration, or other eye diseases.

    What Can I Expect during Recovery?

    You should avoid strenuous activity and lifting heavy objects for a short time following surgery, but most other normal activities can be resumed almost immediately. Slight discomfort, itching, and light sensitivity are common during the first few days after surgery. Your eye surgeon is likely to recommend eye drops to prevent infection, and you should follow all of your surgeon’s instructions for aftercare.

    What Will My Vision Be Like after Surgery?

    IOLs offer a degree of vision correction, so you will likely need a new prescription for your glasses and contact lenses after recovery. Because the clouded lens will be removed, you should be able to see much more clearly. Glare, poor night vision, and double vision caused by cataracts will also be eliminated.

    If you would like to explore your options for cataract surgery, call Gerstein Eye Institute of Chicago at (773) 649-5532 to schedule a consultation with an eye surgeon. Established in 1968, we are a leading eye center for cataract surgery and LASIK. Please call or visit our website today.

    How LASIK Surgery Can Correct Your Vision Problems

    Last updated 7 months ago

    Laser-assisted in situ keratomileusis (LASIK) is a popular type of eye surgery used to correct refractive errors and dramatically improve vision. LASIK is capable of correcting nearsightedness, farsightedness, and astigmatism. If you find corrective lenses cumbersome, consider talking to your eye doctor about whether you could be a good candidate for LASIK. 


    If you’ve ever broken your eyeglasses, lost a contact lens, or had an eye infection due to your corrective lenses, you may have already considered undergoing LASIK surgery. This innovative procedure offers the freedom and convenience of no longer having to depend on eyewear. LASIK surgery has a very high rate of patient satisfaction. You’ll enjoy vision correction no later than a few days after your procedure. Plus, the laser application takes less than one minute to complete!


    Your eye surgeon will apply numbing drops to the eye to eliminate the possibility of any discomfort. Then, he or she will create a very small flap in the cornea. Sometimes, this is accomplished with a microkeratome, which is a special mechanical blade. Many patients prefer bladeless LASIK, which involves the use of a femtosecond laser to create the flap, rather than a blade. After the flap is created, the eye surgeon applies an excimer laser to reshape the cornea. Reshaping the cornea allows the eye to focus light properly, which corrects vision.


    Over the years, LASIK technology has undergone a number of improvements. In addition to bladeless technology, some eye surgeons use the Allegretto Wave Eye-Q excimer laser. This laser operates at a very fast speed to reduce the procedure time even further. Plus, the laser is highly customizable, allowing the eye surgeon to adjust it to each eye’s unique structure. This provides a higher quality of vision.

    Gerstein Eye Institute is proud to offer bladeless LASIK surgery, which gives our patients a safe and precise option for eye surgery. We also use the Allegretto Wave Eye-Q to customize each procedure to each patient’s unique eyes. You can schedule a consultation with our practice in Chicago by calling (773) 649-5532.

    Age-Related Eye Diseases and Conditions

    Last updated 7 months ago

    Advancing age often places you at a higher risk of certain conditions, even if you’ve led a generally healthy lifestyle. It’s a good idea to schedule regular appointments with an eye doctor to check for signs of age-related eye conditions, such as cataracts, macular degeneration, and glaucoma. When an eye doctor detects these problems early, patients are less likely to suffer from complications such as permanent vision loss.


    Cataracts are areas of cloudiness on the eye’s lens. They cause cloudy or foggy vision. Often, patients with cataracts report having difficulty driving at night and coping with glare. Over half of all adults over the age of 65 have cataracts, and cataract surgery is among the most common types of eye surgeries. Although age is a significant factor in the development of cataracts, other risk factors can contribute. For example, you’re more likely to get cataracts if you smoke, consume alcohol immoderately, or do not protect your eyes from exposure to ultraviolet light.

    Macular Degeneration

    Your retina is located at the back of the eye. The macula is a small area in the retina that allows you to discern fine details. For example, the macula is the reason why people can read small print or thread a needle. Age-related macular degeneration (AMD) occurs when the macula deteriorates, causing symptoms such as blurry vision and dark areas in the central vision. Sometimes, permanent central vision loss occurs.


    Glaucoma is another condition that is more prevalent among older adults. Glaucoma is a group of eye diseases characterized by damage to the optic nerve. The optic nerve can become damaged because of increased intraocular pressure, or pressure within the eye. Early detection is critical to prevent permanent vision loss.

    The eye doctors of Gerstein Eye Institute in Chicago have extensive experience in detecting and treating numerous eye conditions. We offer cataract surgery with advanced technology intraocular lenses, among many other innovative treatments. Call our eye surgery practice at (773) 649-5532 to schedule an appointment.

    How Advanced Technology Intraocular Lenses Can Restore Vision

    Last updated 7 months ago

    Cataracts are a common vision problem that causes progressively worsening vision loss. If you have cataracts, your ophthalmologist may recommend undergoing cataract surgery. This type of surgery involves removing the cloudy lens and replacing it with an intraocular lens (IOL). Your ophthalmologist may recommend an advanced technology IOL such as the AcrySof Toric lens. Not only does this innovative lens restore your sight following cataract removal, but it can also reduce or eliminate astigmatism. Patients who receive this IOL enjoy significantly improved distance vision, without the need for contact lenses or eyeglasses.

    Advanced technology IOLs are an exciting development in the ophthalmology field because older adults can once again enjoy the same vision quality they had in their younger years. These IOLs are ideal for restoring near, intermediate, and far vision. Plus, these lenses have been proven to be just as safe as traditional lens implants.

    To determine whether you could be a good candidate for advanced technology intraocular lenses, call Gerstein Eye Institute at (773) 649-5532 and make an appointment with our eye doctor. We also invite you to browse our website for more helpful information on cataract surgery.
