People with hyperopia, also known as farsightedness, can usually see objects in the distance, but their close vision is blurry. Symptoms of untreated hyperopia include: Difficulty concentrating on near work, such as reading Eye strain Headaches after reading or other activities involving close focus Aching, burning eyes Irritability from concentrating on tasks In children, eyes…
Treatment for glaucoma often begins with medicated eye drops. The goal of these medications is to lower the pressure in the eye (intraocular pressure) and prevent damage to the optic nerve. To gain the most benefits of these medications, use them exactly as prescribed by your eye doctor. Sometimes your doctor may prescribe more than…
Collagen crosslinking (CXL) is a relatively new procedure used to treat patients with keratoconus. Keratoconus is a thinning of the corneas which causes them to form a cone shape and bulge outwards. Many countries outside the U.S. use CXL, but the procedure hasn’t yet received FDA approval. However, since 2008, many people with keratoconus have…
Presbyopia is the gradual decline in close vision that occurs with age. The condition occurs as the lens in the eye stiffens and loses its flexibility, thereby impairing its ability to focus at images or objects up close. While multifocal prescription glasses, such as bifocals, are one possible treatment option for presbyopia, the popularity of…
Laser-assisted in-situ keratomileusis, or LASIK, is the most common type of refractive surgery. If the curvature of your cornea deviates from the ideal curvature, light entering your eye will bend (refract) incorrectly. This is known as a refractive error and can cause vision problems. For many patients, LASIK safely and successfully corrects the shape of…
When the cornea is misshapen, light bends (refracts) incorrectly, leading to vision problems. Refractive surgeries aim to reshape the cornea, thereby improving vision. LASIK is one of the most popular types of refractive surgeries. However, not everyone is an appropriate candidate for LASIK. Fortunately, photorefractive keratectomy (PRK) is often a suitable treatment option for patients…
Glaucoma is a condition characterized by excessive pressure in the eye, or intraocular pressure. This irregularly high pressure is due to a buildup of fluid in the eye. As intraocular pressure increases, it can compress the eye’s optic nerve, eventually leading to vision loss. Around 3 million people in the United States have glaucoma; although…
The iStent Trabecular Micro-Bypass is a surgical device that is available for use in treating patients with mild-to-moderate open-angle glaucoma. Glaucoma is characterized by an excessive accumulation of fluid inside the eye, which leads to an increase in the inner eye pressure (intraocular pressure). This can damage the optic nerve and lead to a gradual…
Corneal transplantation is a surgical procedure to replace part of a damaged or diseased cornea with corneal tissue from a donor. The cornea is the transparent, dome-shaped surface on the front of the eye. It plays a large part in vision by helping to focus light onto the retina. Reasons for Corneal Transplantation If the…
Intacs Intacs, or intracorneal ring segments (ICRS), is a non-laser treatment for mild nearsightedness. It can also be used to treat the astigmatism and nearsightedness that occurs with keratoconus, one type of corneal disorder. How Intacs Works Intacs is a pair of crescent-shaped plastic devices that are implanted in the eye. During the procedure, an…
