LASIK is a popular surgical procedure used to correct conditions that affect vision such as nearsightedness, farsightedness, and astigmatism. Almost all patients will gain their desired vision after the procedure. Also, while changes made to the cornea cannot be reversed, in most cases, patients have reduced or lost altogether their dependence on using eyeglasses and contact lenses.
Before scheduling a LASIK session, you have to meet with an eye surgeon who will discuss what to expect during and after it. An evaluation of your medical history will be performed along with a thorough examination of your eyes. These steps are needed to determine whether you are a good candidate for the procedure. If you are wearing contact lenses, it is strongly advised that you do not wear them for at least three weeks before your evaluation.
At this point, you should also tell the doctor about the medicines you are currently taking (including over-the-counter products) and other medications that you might be allergic to. Take time to weigh the possible risks and benefits of undergoing the procedure, asking your eye doctor for input as needed.
Remember that the results of the LASIK procedure cannot be reversed. Do not hesitate to ask your doctor for detailed information about it.
Ask anyone about which sense they fear losing the most, and a majority would definitely give “eyesight” as their answer. It’s not difficult to understand why: humans function and react based mainly on what they can see. Eye doctors can attest that only with proper care and maintenance will our eyes serve us well in our lifetimes, with little or no impairment whatsoever.
Eat right to see right
Proper nutrition will help keep your vision clear as well as maintain overall health. Vegetables like carrots contain Vitamin A that is beneficial to eye health; a deficiency in this important nutrient often results into xerophthalmia, or drying of the eyes which could lead to permanent blindness. Food that contains antioxidants and zinc is also good for the eyes.
If you were born with defective eyes, you could develop congenital eye disorders such as astigmatism, myopia, and glaucoma. These can be corrected via surgery, eyeglasses, or eye drops. Patients with cataracts and macular degeneration should consult an ophthalmologist.
Each time you go out into the world, anything from a speck of dust to sunlight can result in eye discomfort and might even escalate to something serious. Use protective eyewear when travelling or working with industrial equipment to avoid flying debris. Dark sunglasses with ultraviolet-rated protection should be used to prevent damage caused by intense light. Also, avoid rubbing your eyes with your hands and reading in dim light.
Some residents of Durham, North Carolina, will have caught the bug to fly. The city is host to an engine facility for General Electric Aviation, and at least three companies in the area offer flight training or air charter services. If you want razor-sharp vision to aid your capacity as a pilot, consider getting LASIK through Durham, NC practices like the North Carolina Eye, Ear, Nose & Throat.
The joint study revealed that it’s the eye pressure that compounds the inflammation by activating a protein that works against microbial infections. Research co-author Dr. Zhang Kang says that the anti-microbial protein also kills cells in the retina. The only treatment seen to inhibit the eye’s production of these substances at present is a drug that’s already undergoing tests for cancer and stroke patients.
Most people are aware that LASIK surgery is a procedure that aims to restore a person’s efficient vision. However, some of its aspects are still unknown to most people. As such, here are the answers to a few of the most frequently asked questions regarding LASIK surgery: Continue reading →
At one point in time, some doctors specialized in eye, ears, nose, and throat health. They were known as EENT doctors. However, all these changed in 1979.
Ophthalmology and otolaryngology grew together during the early 20th century. In 1903, the American Academy of Ophthalmology and Otolaryngology was formed, dedicated to the major advancement of both fields. Its recruitment base expanded from the New England area to the rest of the United States. Continue reading →
Either constantly or intermittently, the condition may manifest in the eye appearance. The eyes may be visibly crossed or misaligned (i.e. one is deviated upward, downward, or to the side). Alternatively, the eyes may not move together, or one or both eyes may move to another direction while looking at something—a condition known as “wandering eye”. Older children may also complain of double vision or sensory loss in one eye. If these signs are present in your child, take him/her to an eye doctor in Durham, NC for diagnosis and treatment.
There are various possible causes behind strabismus. The most common is farsightedness or other focusing problems that have been left untreated. Other congenital or genetic diseases like Down’s syndrome, cerebral palsy, and cataracts; as well as bleeding, tumorous, or nervous disorders may also result in strabismus. These conditions can weaken the eye muscle or the nerve that controls it, and manifest as crossed eyes.
Does your vision blur no matter how near or far you are from an object or person? Do you often find yourself squinting trying to see well? Do you often experience eye strain or headaches, especially after reading or prolonged computer use? If you said yes to any of these questions, you may have astigmatism. Continue reading →
For the record, eye color has little to no bearing on visual acuity. However, it may tell a different story about a person’s optical profile.
Before delving into details, it’s important to know how eye colors are formed. Brown is the most common color, shared by over half of the world’s population. Brown eyes come from inheriting at least one dominant gene from one or both parents. Due to variations in genetic coding, it’s possible for both blue-eyed parents to have a brown-eyed offspring.
Perhaps the biggest impact eye color has on a person, other than defining his or her looks, is light sensitivity, or photophobia. Brown eyes are less light-sensitive because of the high presence of melanin in them, as produced by a gene known as OCA2. On the other hand, light-colored eyes can be more light-sensitive as they have less protective pigments.
This puts athletes with blue eyes at a slight disadvantage, as their reduced resistance can blind them while playing on a sunny day. The glare can also disrupt an affected person’s situational awareness, an essential skill in daily life that can save one from a roadside mishap.
Other causes of photophobia include contact lens irritation, corneal abrasion, and meningitis. Because of its possible implications, it is important to have this condition checked by an eye doctor, who can make a proper diagnosis and prescribe the right solution.
