The Fuzzy Facts of Myopia

For a student, the onset of childhood myopia can be a frustrating and confusing experience. Squinting to see the blackboard, difficulty concentrating and a decrease in participation in class are all classic signs that a child is experiencing nearsightedness. Once properly diagnosed with myopia and fitted with corrective lenses, the difference in the child’s performance in school and their general happiness is very noticeable.

An abnormal oblong shape to the eye does not allow light to refract as it should. Myopia occurs when blurred images are transmitted to the brain when the cornea and lens overly bend the light coming into the eye, causing a refractive error in the retina. Genetics play a role, but environmental influences such as close computer work, using lighted instruments such as lasers and general eye strain are contributing factors. Other outside influences or health issues can cause episodes of nearsightedness that are not diagnosed as myopia. Night myopia occurs when dim lighting changes the eyes ability to focus in dark conditions. Diabetes can cause nearsightedness as one of the first signs that cataracts are forming in the eye. People who perform up close work can sometimes experience a temporary nearsightedness that corrects itself once the eyes are rested.

 

The occurrence of myopia is highest in school age children and young adults, and is the world’s most common eye dysfunction. The condition is most often diagnosed, by an ophthalmologist or optometrist, after a teacher realizes a student is having difficulty reading the blackboard and is starting to struggle with schoolwork. Studies around the world indicate that in the last several generations, the cases of nearsightedness have increased especially among school-aged children. While familial inheritance of the disease has been proven to increase the likelihood of myopia, outside aspects such as close reading work have greatly contributed to the number of those affected in recent generations. The exact nature of how environmental issues and inheritance combine to produce myopia remains unknown.

There are a certain number of people affected with nearsightedness, who can benefit from one of three different surgeries to correct the refraction in the eye. The repair improves the focus of the light rays on the retina by reshaping the cornea. Well known LASIK surgery, radial keratotomy and photorefractive keratectomy are all done as outpatient surgery, on those whose condition warrants surgical intervention. For others, corrective lenses and eye glasses are the myopic treatment of choice. No preventatives exist for myopia, but the treatment options allow the person with nearsightedness to once again see clearly into the distance.

Going Under the Laser: Thinking about Laser Eye Surgery

Very few people today can claim that they don’t use contact lenses or glasses. Brainstatistics.com notes that 75 percent of the American population (225 million people) use some form of corrective lens. Yet others are diagnosed as needing corrective lenses, but they choose not wear them for fear of inconvenience or cost.

Indeed, both contacts and glasses come with their pro and cons. Whether it is cleaning contacts regularly, taking time to enter them in the morning, or taking them out at night, contacts can be a nuisance. Likewise, trying to keep track of glasses can be a chore (also see What to Do With Your Old Glasses After Lasik Surgery). Many people have wondered whether there’s an easier way to see clearly, one that doesn’t disrupt their daily lives.

A new option has surfaced: laser eye surgery. This form of correction has shown tremendous effectiveness at correcting vision problems. According to the FDA, doctors reviewed patients over a course of 1, 3, and 6 months, and it was shown that the surgery improved 92% percent of the eyes by 20/20 or higher. Based on the high success rates, many are casting their glasses and contacts aside and turning to laser eye surgery, or Lasik.

Lasik is an elective surgery that can greatly improve eye health, but it’s not for everyone. Lasik surgery is for individuals with nearsighted vision, difficulty seeing objects in the distance, and astigmatism (unclear vision). The ultimate goal is to help a person’s eyes focus more clearly on objects in the distance. This means that despite the clarity from the surgery, an individual may still need glasses or contact lenses to see objects closer to his or her face.

The surgery requires an incision on the cornea, the top clear layer of the eye, and for a laser to pulse UV rays into the eye. Its side effects include slight pain and discomfort for at least seven days after the surgery. There is no one who can give better information about this option than a medical professional, and one can visit an eye clinic in Singapore to find out more.

The first step to considering laser eye surgery is to find out costs of Lasik @lasiksurgery.sg. A doctor can help to assess if Lasik is the right choice, and whether it fits within an individual’s budget. Taking the time to have a few consultations with more than one doctor about your overall eye health is a good step to help determine who is a good candidate for the procedure.

The History of LASIK Procedure

A Colombia based Spanish ophthalmologist Mr. Jose Barraquer is considered as the inventor of lasik procedure. He has first applied this procedure in his clinic in Bogota, Colombia in the middle of last century. He has used microkeratome to cut the thin flaps of the cornea to alter the shape. This technique is known as keratomileusis. He has also developed this procedure which was helpful for long-term result. Radial Kerototomy (RK) is the further development of the LASIK procedure which was invented in 1970 by Svyatoslav Fyodorov. Following the RK, Photorefractive Keratectomy (PRK) was introduced in 1983 at Colombia University by Dr. Steven Trokel. Then excimer laser was used to ablate corneal tissue for the correction of optical errors like myopia, hypermetropia and astigmatism as a advancement of PRK. LASIK was first applied in the United States in 1989, but before that it was implemented in other countries. Faster lasers, larger spot areas, bladeless flap incision, intra-operative tachymetry, and wavefront-optimized techniques have improved the reliability of this procedure significantly.

How Lasik Surgery Changed My Life

Pat wore glasses since the fourth grade. At first her eyesight just needed slight correction, but year after year she kept having to get a stronger prescription. It got to the point where she could only see the top letter on the eye chart clearly.

While in her late twenties Pat kept hearing about the advantages of undergoing Lasik. She asked friends and family what they thought about having the procedure. After talking about it with her eye doctor, they decided to explore to see if it would be a viable option for her. Over the next several weeks she had tests that indeed resulted in the okay from her eye doctor to proceed with the surgery.
Before surgery Pat had to sign papers that she understood that undergoing any surgery involving the eye could lead to blindness, but that there was a very low risk of that actually happening. The doctor told Pat of some Lasik side effects she might experience; such as halos around headlights while night driving and that she had to be careful of riding in a car with an air bag which if it hit her in the face could damage her eyesight until her eyes were fully healed.

So on the morning of the surgery she was a little apprehensive knowing that she would be awake during the procedure. The Lasik surgery itself is quite quick. It only takes about fifteen minutes for the entire procedure. Pat was led into a small room with what looked like a dentist chair with a machine beside it that looks like and x-ray machine. Pat sat in the chair and was prepped for surgery. The doctor positioned the machine and told Pat, “Focus on the blinking light, and don’t move once we start the machine”. The doctor started the machine and after a few minutes he was finished. The doctor then bandaged here eyes was told to go home and rest. If she felt pain she could use any over-the-counter pain reliever of her choice. The next morning she returned to the Lasik surgery clinic and they removed her bandages and checked her eyesight it was twenty/fifteen in one eye and twenty/twenty in the other eye.

The first morning that Pat woke up with restored eyesight she was amazed to be able to see photos hanging on the wall across the room clearly. Before she had Lasik surgery everything was fuzzy unless it was about six inches away from her face. Pat was amazed that she could now distinctly see the different greens in a close group of trees. She kept scaring herself because now her peripheral vision was allowing her to see things she had never been aware of.
