LASIK Surgeons on the Most EffectiveTreatment for Refractive Error

Around 80 percent of the information that the brain receives is delivered by the eyes. This means you owe to your eyes much of your knowledge of the world around you. The eyes are the fastest-moving and somehow the most extensively used organs in the body. So it’s only right that you take good care of your eyes at all times.

How the Eyes Work

When light hits an object, it is either absorbed or reflected. Absorbed light stays within the object, while reflected light is scattered in all directions. There are only a handful objects in the universe that do not reflect light, such as the black hole. Everything else does. When the light reflected by the object reaches the eye, visualization takes place.

The reflected light enters the eye through the cornea and is filtered by the pupil to eliminate excess light that could harm the retina. Photosensitive cells within the retina send information about the light they received to the brain. Read more from this article: http://bit.ly/2DMwnyU

LASIK Surgery: How It Can Help Correct Refractive Error for Good

Worldwide, over 624 million people are suffering from vision impairment due to refractive error. When left uncorrected, this condition can worsen and affect a person’s ability to function optimally and engage in activities of daily living. Thanks to modern technology, refractive error can now be treated by using wearable lenses or through surgery.

Although eyeglasses and contact lenses are effective in correcting the main types of refractive error—myopia, hyperopia, and presbyopia—a lot of people these days are preferring surgery, particularly laser-assisted in situ keratomileusis (LASIK), and for a plethora of good reasons. Apart from being a quick procedure (lasting about 30 minutes or less), LASIK promises guaranteedresults. It is also not invasive, which is why it can be done using minimal anesthesia with conscious sedation.

How Does LASIK Work?

Unlike other types of surgery that consist of multiple steps, LASIK only involves two—flap creation and corneal reshaping. Of course, prior to surgery, a comprehensive exam will be performed by the eye doctor to determine if the patient is a candidate for surgery and if certain risks factors have to be managed. Once the patient’s suitability is established, the surgery will be scheduled. Read more from this article: http://bit.ly/2n8KF1D

Life After Laser Eye Surgery: Is LASIK Really a Permanent Solution?

Despite plenty of scientific evidence to the contrary, some LASIK myths just don’t seem to go away. For instance, many people still think that the results produced by this form of laser eye surgery only last for a few years. This is simply not the case. LASIK will permanently correct vision problems that a patient comes in with to have the procedure, including astigmatism, nearsightedness and farsightedness.

Learning more about how LASIK corrects vision may help you put such a rumor to rest. Here are a few facts that can shed light on this matter.

How LASIK Works

The excimer lasers used by an ophthalmologist during the procedure are designed to reshape the cornea itself. This enables light to enter the eye properly and be focused onto the retina. Doing so eliminates the imperfections in your eye that are causing myopia, hyperopia or astigmatism, resulting in clearer vision. In and of itself, reshaping the cornea is a permanent process. Meaning, it is impossible for your eyes to revert to their previous state afterwards. Read more from this article: http://bit.ly/2DEmpiU

Why a LASIK Surgeon Might Advise Patients Not to Rush to Have the Procedure Done

With FDA approval and a high patient satisfaction rate, LASIK is perhaps the most well-known method of vision correction out there. Nevertheless, those interested in this procedure would do well to remember that it is still a form of refractive surgery. As any board-certified LASIK surgeon in Orange County will tell you, it is not for everyone. There may be factors or existing conditions that make you a poor candidate for the operation.

Just because your doctor advised against going through with LASIK now, however, doesn’t mean that you can’t have it done later on. Sometimes, postponing or delaying the surgery is the best course of action. If any of the following circumstances apply to you, you might want to wait just a little while longer.

You’re Simply Too Young for LASIK

Currently, the FDA has only approved LASIK for patients over the age of 18. Most providers also won’t perform the surgery on those who are not yet in legal age, and will often encourage young adults to wait a few more years before having the procedure. This is because the vision of those who are under 18 are still subject to many changes. For instance, you may have a case of refractive instability, which can cause complications during the operation. If possible, it’s best to wait until you’re in your mid-20s.

Five Reasons Not to Put Off LASIK Surgery Out of Fear of the Procedure

Having LASIK surgery, or any kind of eye surgery for that matter, is an important decision that will have a profound impact on your life. It is understandable, therefore, that you may harbor some fears or anxiety towards the procedure itself. However, what you need to keep in mind is that laser surgery from decades ago is not the same as it is today.

Through continued improvements, cutting edge technology and advanced surgical skills possessed by today’s specialists, LASIK has now achieved an unprecedented 96 percent patient satisfaction rate, according to the American Refractive Surgery Council. Patients considering the procedure have absolutely nothing to worry about, but to further ease your worries, here are five reasons why you should not be afraid of LASIK.

Virtually Painless

Because LASIK surgery is done while the patient is awake, many automatically assume that it’s a painful procedure. You’ll be glad to know that this is simply not true. Yes, your eyes will be open while the surgeon operates on you, but your doctor will apply numbing eye drops and administer a mild sedative so you don’t feel any discomfort.

LASIK Eye Surgery Can Help You Get 20/20 Vision for Careers Where Perfect Eyesight Is Required

Have you ever wondered why some jobs require people to have perfect eyesight? For the most part, these careers have a high standard for vision due to the nature of the work to be performed. In some types of job, an individual’s ability to perceive depth, color, distance and other similar visual aspects can mean the difference between life and death. Take for example air force pilots, air traffic controllers, firefighters, airline pilots, and astronauts who may be entrusted with the lives of many on a daily basis.

This explains why strict requirements are in place and other preconditions must be met by applicants depending on their choice of career and employer. Before significant advancement in vision correction, this might be a problem for many hopeful applicants. Today, however, LASIK eye surgery can help you fulfill your dreams of working in your desired field.

Defining 20/20 Vision

To help you better understand what optimal vision entails, you must learn what it actually means to have 20/20 vision. This measurement is derived from the Snellen Chart—the black and white eye chart commonly seen at an eye doctor’s exam room—which displays a number of lines and letters that progressively get smaller the farther down you go. Opticians used millions of results from the Snellen Chart to determine what the “normal” level of sight is among the population, which happens to be 20/20.

Cataract Surgeons Highlight the Three Primary Types of Age-Related Cataracts

As you age, your risk for cataracts increases. It is also very likely that you will develop any one type or a combination of any types of cataract over time. Therefore, understanding the different kinds of cataract is of utmost importance. Being privy to such vital information can help both you and your doctor determine the best treatment option for you.

Cataract surgeons categorize age-related cataracts into three primary types: nuclear sclerosis, posterior subcapsular, and cortical. Each one differs from the other in terms of anatomical location, appearance and underlying conditions.

Nuclear Sclerosis

Nuclear sclerotic cataract is considered to be the most common among all age-related cataracts. It gradually forms deep within the central zone or the nucleus of the lens, hence the name. It initially presents as a central yellowing and hardening of the lens, accompanied by opacification. Nuclear sclerosis is also known to progress slowly and may take years before it can affect your vision. Read more from this article: http://bit.ly/2EO57Mz
