• Comparing How Nearsightedness and Farsightedness Affect Your Vision

    When someone suffers from nearsightedness or farsightedness, that person’s eyes are not properly shaped, which means that they cannot bend light the way they should for perfect eyesight. Both nearsightedness and farsightedness can negatively affect vision clarity . Continue reading to find out how these different conditions impact vision.


    Nearsightedness, which is also called myopia, occurs when a person either has an eye that is too long or a cornea that curves too much. Because of the way light hits the retina, a person who is nearsighted has difficulty seeing objects that are far away. Without some kind of corrective lenses, objects that are far away appear blurry. A person with myopia can see objects that are close by without issue, however. Glasses or contacts can improve the way the light hits the retina so a patient has no more trouble seeing far away objects.


    Farsightedness, or hyperopia, is a condition that occurs when a person’s eyes are too short or when the corneas do not curve enough to send light correctly to the retinas. When someone has hyperopia, he or she has trouble seeing items that are close by, but can usually see far away objects with no problem. The eyestrain associated with farsightedness often leads to headaches, aching or burning eyes, and difficulty concentrating. If you have hyperopia, your eye doctor will probably give you a prescription for either glasses or contact lenses to correct the issue.

    In addition to corrective lenses, LASIK surgery is a treatment option for both nearsightedness and farsightedness. Dr. Mark Hornfeld of NYC can help address these vision problems, as well as many others.

  • Looking Back at the History of LASIK Surgery

    LASIK surgery has helped millions of people correct optical issues that affect their vision. If you and your ophthalmologist have discussed this procedure as a possible treatment for your eye issues, keep reading to learn more about the history of this revolutionary procedure and how it has improved through the years.

    Lasers and Eye Treatments

    In the 1970s, the invention of the excimer laser gave Stephen L. Trokel, a researcher at Columbia University, a reason to study how this laser could be used to correct vision issues. By 1988, Trokel’s colleague, Marguerite McDonald, performed the first photorefractive keratectomy (PRK) surgery on a woman with malignant melanoma. By 1991, Canada officially approved the excimer laser and used it to perform PRK surgery—the U.S. followed suit in 1995.

    Advancements in Laser Eye Treatment

    In 1990, Greek eye doctor Ioannis Pillakaris and Italian eye doctor Lucio Burrato managed to make this new laser eye surgery more effective. Instead of pointing the laser to the top of the corneal surface like doctors had been doing, they decided to cut a small flap in the cornea and use the laser on the underlying tissue. Once this was complete, they replaced the flap. These new additions made the procedure more effective and reduced recovery time, which paved the way for modern LASIK surgery.

    Better Precision for LASIK

    By 1999, doctors figured out how to use technology to actually map a patient’s prescription. Each corneal map serves as a kind of fingerprint for a specific person. Using this technology allows ophthalmologists to get even more precision with laser treatments, so they can offer their patients the best results.
