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.
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 →
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.
Many people today assume that it’s all downhill when their eyesight begins to lose its usual sharpness. Fortunately, one does not have to resign himself or herself to to wearing spectacles just yet: LASIK surgery can help blurry-eyed patients recover their ailing vision.
The surgery, however, will render the patient’s eyes sensitive for an amount of time. It is important for these patients to properly take care of themselves and their eyes, or they risk losing what they had repaired at the hands of a reliable professional.
Here are some tips that can help patients recover post-LASIK surgery:
Be Careful Around Water
The eyes are still sensitive after the procedure it went through, so exposure to water may nullify (or worsen) their condition. Patients should not take a bath for a day after the procedure, nor should they get soap in their eyes.
LASIK surgery is not a procedure that affects physical function significantly, but it is important to be careful with certain activities. Exercise and swimming should not be done for a week. It is also important to avoid rubbing the eyes a month after the procedure, as tempting as it might be. Eye makeup must also be avoided for a week.
These steps will help ensure the success of the LASIK eye surgery, and will help people like you to live spectacle-free lives.
Glaucoma is an eye disease caused by excess pressure in the eye due to poor circulation of eye fluids. If left untreated, the pressure could damage the optic nerve and cause permanent blindness; in fact, it is the second most common reason for blindness in the world.
Most of the risk factors for glaucoma, such as age and race, are out of your control. However, there are a few things you can do to minimize your risk:
Make smarter decisions when eating. Cutting down on trans fats helps lower high blood pressure. This means reducing the amount of fried foods and processed foods in your diet.
Increase the amount of fish, particularly ones rich in omega-3 fatty acids like salmon— in your diet. Blueberries and cranberries are rich in bioflavonoids, which strengthen the capillaries in the eyes, allowing more essential nutrients to reach it.
Regular exercise has been proven to be effective in lowering your intraocular pressure (IOP). You do not need to work out in the gym like a bodybuilder to achieve this effect though. Moderate exercise like jogging three times a week is enough to lower your IOP.
Take note that you can still develop glaucoma despite following the tips above, especially if you have a family history of the disease. With that in mind, it is best that you see an ophthalmologist for a thorough eye exam every year once you reach the age of 40.
LASIK is a corrective surgical procedure that reshapes a patient’s cornea to improve vision. This treatment may get rid of such conditions as near-sightedness, far-sightedness, and astigmatism. LASIK is known to be very effective, but not all patients can undergo the procedure. Those who are thinking of getting this treatment must first consider a few details. Continue reading →
Do you have trouble reading objects from a distance or up-close? Then it is likely that you have a refractive error, a condition wherein the shape of your eye prevents sufficient light from focusing on your retina. Refractive errors come in one of four major types: myopia, hyperopia, presbyopia, and astigmatism. You need to go to reliable eye doctors and get tested to get proper diagnosis. Continue reading →
