Lasik Procedure - Impact on Human Health & Ethical Issues

Impact on Human Health & Ethical Issues

After the Lasik procedure, the eyes may feel irritating or itchy and sometimes they may feel as if they are burning which will cause them to become watery. Due to having frequent tears in the eyes, the vision becomes blurry. Additional procedure could be a possibility if the eyes get continuously rubbed which could affect the corneal flap. It could be shifted or dislocated and to reposition it, an additional procedure may be required. Often there would be discomfort and pain in which the doctor would provide pain killers but there would still be many symptoms. Light sensitivity, hazy vision, along with reddened eyes are the most common symptoms after the procedure and if your condition gets worsened then you should contact your doctor as soon as possible without wasting any time. Your vision could be blurry for a couple of days after the surgery, but during your first postoperative visit, the doctor would recommend you to continue using antibiotics, fake tears after examining your eyes. Doctors may also recommend taking rest and not participate in sports for a few days or sometimes weeks depending on your recovery. Pools, and lakes will be advised to keep a distance from as eye infection could occur, rest your doctor will let you know when you could start participating in your regular activities.

It is recommended that do not apply any sort of makeup, creams or perfumes as they could also risk for an infection, but again your doctor will let you know when to use them. Your vision could change various times during the first few months after the surgery but your vision should be stabilized by two weeks. You may face hardships in driving at night, and having a glare but that will also be part of the process of your vision’s stabilization. If you are facing problems with your vision then immediately visit your doctor in order to get a checkup; vision loss could be the result. Additional treatments may be applied but before any further steps, you should have your eye measurements done to know whether your vision would improve with the enhancement. Risks still apply in the initial surgery and there are no guarantees of a positive result.

There is not always a positive result after the surgery since the possible outcomes may be vision delusion, the results may not be permanent for a life time. After the surgery glasses or contacts might be still needed and more overly vision loss is one of the biggest risks. Lasik could also make your vision worse during the night and it could make the dry eye symptoms worse. Along with the negative results, there are some positive points as well. The procedure of Lasik is pretty fast and is approximately 10-15 minutes and painless. Since the computer guides the laser, the results are precise and accurate.

Some ethical issues that apply in the Lasik surgery are confidence. Many patients don’t have much confidence in the procedure because of the disadvantages, negative results and side effects. People often continue to wear contacts or lenses because they fear that their eye sight may worsen or may result in a vision loss. Along with confidence, fear is also there. Fear that the process may not guarantee a life-time without glasses and lenses and fear of having the worst symptoms which may last over a long period of time. Many fear of vision loss or vision blur and some fear the actual process in which a blade is used. Visual aberrations such as having each eye visualizing two different sizes and or the increased sensitivity of light towards the eyes are another fear.

Lasik Procedure - How it Works

How it Works?

Laser Eye Surgery is the process which many people choose over wearing glasses or contact lenses, but many don’t know the process, advantages, disadvantages and the side effects after this procedure. Lasik and Lasek are two different laser eye surgery procedures but the most common and popular procedure is Lasik because it is more comfortable and less longer than Lasek. The recovery time after having Lasik is far less than Lasek since to recover from a Lasek procedure, it may take over a week whereas people could be doing their regular activities within a time span of 48 hours. Hence the Lasik procedure is more common than the Lasek procedure.

One of the major differences between a Lasik procedure and a Lasek procedure is that during the Lasik procedure, a flap is created. The flap is made of the outer transparent part of the eye; which is called the cornea, and before the laser is applied, the flap is separated from the surface of the eye. Intralase describes how the flap is created during the Lasik procedure. During the standard Lasik, the flap is created by using a microkeratome; which is a surgical blade, while a laser is used during Intralase. In most cases, Intralase is often considered to be a more exact and safer procedure than standard Lasik because no blade is used during the procedure unlike the standard Lasik procedure. People find Intralase as a better procedure since no blade is being used.

Both Lasik and Lasek have Wavefront which describes the way the laser is applied. Wavefront is more of an accurate eye surgery compared to a standard Lasik or Lasek procedure. In this procedure, many measurements are taken across the cornea while only a few are taken during the standard Lasik procedure. The chances of the vision you achieve after the Wavefront procedure are 20:20 which is much better than the standard Lasik procedure.

During the actual laser surgery, the cornea is reshaped depending on your prescription and the vision is also blurred due to one major reason which leads to two different ones. The retina at the back of the eye is affected by the light entering the eye does not focus properly which leads to a blurry vision. The vision is also affected whether you are long sighted or short sighted, and these two different sights have different effects on the vision during the laser eye surgery. The light slips back of the retina if you are long sighted while the opposite happens if you are short sighted. When the light is focused on the retina, chances are that you will have a 20:20 vision and will not need lenses or glasses.
