• Understanding the Symptoms of Glaucoma

    Infected eye

    Glaucoma is a common, yet misunderstood, eye condition. It is one of the leading causes of blindness in the United States, but few people understand their risk of developing the condition. Anyone can get glaucoma, but it is most common in older people and African Americans. Could you be experiencing the symptoms of glaucoma? Here is a look at what you need to know.

    Open-Angle Glaucoma Symptoms

    Open-angle glaucoma is the most common form of the disease, and unfortunately, it doesn’t have many symptoms in its early stages. With this kind of glaucoma, the eye drainage canals become clogged, which causes pressure to rise in the eye. Over time, the pressure damages the optic nerve. At first, most patients don’t notice any changes in their vision, because initially, only peripheral vision is compromised. Because open-angle glaucoma progresses so slowly, by the time most patients begin to notice vision loss, the disease is in an advanced stage. Open-angle glaucoma’s status as a silent disease is one of the reasons why having regular eye exams is so important. An ophthalmologist can detect glaucoma in its early stages, when treatment is possible, by testing your eye pressure.

    Angle-Closure Glaucoma Symptoms

    Angle-closure glaucoma is much rarer than open-angle glaucoma. With this type of glaucoma, which is caused by a complete blockage of drainage canals, symptoms set in very quickly. Sudden vision loss, headache, and nausea that occurs with severe eye pain are all common symptoms with this type of glaucoma. Angle-closure glaucoma is a medical emergency.

  • What Is Nearsightedness?

    Nearsightedness – or myopia – is a very common vision problem. People who are nearsighted can see fine up close but struggle to see things in the distance. It often runs in families, and in some cases, it gets worse with age. Nearsightedness can be treated with glasses, contacts, or refractive surgery.

    Nearsightedness is caused by a cornea that is curved too much or an eyeball that is too long. These malformations don’t allow light entering the eye to focus correctly. As a result, images focus in front of the retina instead of directly on it. People with untreated nearsightedness often have frequent headaches and find that they have to squint and strain to see. They may also become fatigued while driving or playing sports. Nearsighted children often struggle to see the board at school.

    Glasses and contacts can correct nearsightedness, but why not consider a permanent solution like LASIK? Find out if LASIK is the right choice for you by scheduling a consultation with Dr. Mark Hornfeld. You can make an appointment at our NYC ophthalmologist’s office by calling (646) 681-3100.

  • Getting to Know the Most Common Types of Laser Eye Surgery

    Eye surgery.

    If you’re tired of relying on glasses and contacts to see, laser eye surgery could be the solution you’ve been waiting for. Thanks to major advances in eye surgery in recent years, procedures are exceedingly safe and effective. Millions of people have chosen laser eye surgery to correct their vision problems. There are several different types of laser eye surgery, and while only your ophthalmologist can help you determine which type is right for you, this overview can help you weigh your options.


    LASIK stands for laser in-situ keratomileusis. This refractive eye surgery can correct many common vision issues, including nearsightedness, farsightedness, and astigmatism. LASIK relies on a laser to reshape the cornea so that light is focused properly. A small cut in the outer cornea is made to give the eye surgeon access to the treatment area. Recovery is fast and the results are long-lasting.


    Photorefractive keratectomy, or PRK, addresses minor cases of the same vision problems that LASIK treats. Like LASIK, PRK relies on a laser to reshape the cornea and improve the way light is focused. The difference is that PRK doesn’t require a cut in the cornea like LASIK does. Instead, a cool stream of ultraviolet light goes directly into the cornea to do the reshaping.


    LASEK is short for laser epithelial keratomileusis. It is similar to PRK. During LASEK, an epithelial flap is created, and then an alcohol solution is used to loosen the epithelial cells. Next, a laser is used to reshape the cornea. In the final step, the surgeon places a contact lens to secure the epithelial cells as they heal. Like other laser procedures, LASEK treats nearsightedness, farsightedness, and astigmatism.
