Lasik Eye Surgery Information

What is Lasik eye surgery?

laser eye surgery processIt is a type of surgical procedure that rectifies certain visual problems, hence reducing an individual’s dependency on contact lenses or glasses. The term Lasik in full is Laser-Assisted in Situ Keratomileusis, and it permanently transforms the shape of your cornea, a clear covering at the front of your eye, using an excimer laser.

It is the most popular type of refractive surgery and it is intended to refract or bend light rays to focus specifically on your retina instead of at some point short or beyond your retina. Its main goal is to produce a sharper, clearer vision.

How does Lasik Surgery work?

During the procedure, a trained eye surgeon (in the particular field) begins by creating a thin, precise hinged corneal flap by means of a microkeratome. He/she then pulls back the flap exposing the underlying corneal tissues, then uses the excimer laser to reshape (ablates) the cornea in an exclusive pre-specified pattern for every patient. The surgeon then gently repositions the flap onto the underlying cornea devoid of sutures.

Who is eligible for this type of surgical procedure?

If you are suffering from any of these eye or vision problems, then you may consider going for this surgery.

  • · Nearsightedness or short-sightedness (myopia)

You are said to be suffering from this vision problem when your cornea curves very sharply or when the eyeball is a bit longer than usual, thus resulting to light rays focusing on the front of your retina resulting to blur distant vision. This means that you can see things that are near more vivid, but not those far away from you.

  • · Farsightedness or long-sightedness (hyperopia)

This occurs when your eyeball is shorter than average or you cornea is very flat, resulting in light focusing behind rather than on it. This in turn results to near vision and at times distant objects looking blurry.

  • · Presbyopia

This is a vision problem caused by age-related eye changes that lead to the steady loss of your visual strength, or your eyes’ capability to actively change focus on near objects.

  • · Astigmatism

This happens when your cornea flattens or curves unevenly, thus resulting to disruption of your focus of distant and near vision.

Benefits of Laser eye surgery

  • · It is capable of correcting most levels of hyperopia (farsightedness), myopia (nearsightedness), and astigmatism.
  • · Due to the fact that the procedure is guided using a computer, it is very precise and the outcomes are very accurate.
  • · The surgical procedure is quick, usually takes approximately 5 – 10 minutes only and in general it is painless.
  • · In most situations, a single treatment will provide you with the desired results; nevertheless, enhancements are possible if you need them, even several years after the first surgery.

Disadvantages of LASIK

  • · Results may vary from one patient to another due to the fact that they heal differently.
  • · To some people, the surgical procedure may worsen the dry-eye symptoms.
  • · In some situations, the procedure may make certain elements of your vision worse, including your night visions with halos and glare.
  • · Although it happens in rare situations, the surgical procedure may worsen your vision and make them difficult to correct even with contact lenses or glasses.

Facts About Vision Correction

vision correctionNowadays there are quite many different types of vision correction to choose from. Vision correction is basically a field that is ever growing. There are many kinds of correction procedures that you can actually undergo that are completely reliable and successful. One of them is Lasik eye surgery which is very popular today. It has emerged, during the recent years, as an incredible option to a life of glasses or contacts. While initially, Lasik vision correction was determined to have high patient qualifiers to meet, the growing technology and procedures have really allowed for a changing of guidelines thus making it for individuals with many vision problems to effectively receive close to perfect vision correction.

This procedure can resolve the problem of being farsighted, but at the expense of losing the distance focusing. A typical farsighted individual can see distant objects without experiencing any challenge, but with Lasik surgery can truly solve the close focusing problem and the distance focusing is actually sacrificed in the process. A majority of people would consider this as simply trading one problem for another. Nevertheless, research has shown that there is a way this surgery can assist patients that suffer from farsightedness. It seems like the brain of a human being processes influential capabilities when processing the images. An eye exam is normally used to determine which eye is best suited for the distance viewing and that eye remains unchanged. The other eye then undergoes the Lasik procedure and is optimized for the close object focusing.

Laser eyeWhenever the patient views an object, whether it is far away or near, the brain accepts the images from the two eyes and merges them through complex processing. Essentially, one eye focuses on the close up objects while the other on the far away objects. The brain uses both the images and the final result is that the patient can now see both the far away objects and close up objects. If you are at the age where you have started to notice your farsightedness, it may be good to wait a couple of years before undergoing the Lasik eye surgery. The reason is that during the early onset of farsightedness, your eyes usually tend to change regularly, so if you have the procedure performed too early, your changing eyes could actually negate the results in a year or two, therefore you may need to procedure done again. And if you wait until your eyes stabilize or at least the changing process slows down, definitely you are likely to realize longer lasting results.

Coping and Controlling Vision Loss – Causes & Home Care

vision lossLoss of vision can be sudden or gradual, it can be complete when it involve both eyes or it can be partial when only one eye is affected.

Vision loss is considered loss of sight that cannot be corrected to normal level by use of eye glasses. It is totally different from blindness which mostly occurs right from birth.

Common causes

  • Diabetes, it is major cause of vision loss among elderly.
  • Macular degeneration.
  • Cataracts.
  • Accidents such as and spot injuries.

Partial vision loss may differ depending on the cause, for example.

Cataract vision loss is characterized by cloudy or fuzzy vision, while a lot of light will cause glare.

People who suffer vision impairment out of diabetes, they will have blurred vision, difficult seeing at night and missing area of vision.

With macular degeneration, the side vision will remain normal but central vision will be gradually lost.

Other causes include:

  • Obstructed blood vessels
  • Difficulties of premature birth.
  • Difficulties of eye surgery.
  • Lazy eyes.
  • Stroke
  • Tumors, for example, retinoblastoma.

Home care

For those complete vision loss, you they will not drive and perform most of domestic chores, thus they will need to be assisted. For those suffering partial vision loss, they will be assisted in some activities that requires in-depth observation such as driving and sewing.

Coping with vision loss

Vision loss is a very difficult condition that requires a lot of moral support. But some causes such as diabetes and some corneal diseases can be treated so that vision is restored or maintained.

Some conditions especially those that arises out of chemical or spot injuries may not be treated and this may lead to blindness.

You can cope with vision loss by;

Discussing with your eye doctor (we suggest Dr Michael A McMann MD), if you are employed, you need to talk with your boss so that you can be assigned duties that will not put you into risk or those that you may not be able to handle.

Look for Therapeutic Counseling

Vision loss is a major traumatizing life event that can bring loneliness, depression and anxiety. You need to seek counseling and family members should be supportive to ensure patient does not suffer such feelings.

The patient may also attend some classes that will enable him/her to live confidently with some self-independence.

Patient may also use low vision aids such as:

  • Telescope glasses.
  • Lenses that will filter light.
  • Hand magnifier.
  • Reading prism.


For chemical and spot injuries, ensure your eyes are free from chemical or any material that may injure your eyes.

Loss of vision as a result of diseases can be mitigated by seeking medical attention immediately you notice some sort of vision impairment.

It is good to have good diet such as carrots will help in lowering the risk of suffering vision loss.

Understanding Cataract Surgery

A cataract is an eye condition that is characterized by the clear lens of an eye becoming opaque or cloudy and thus causing a decrease in vision. Cataract SurgeryIt is the role of lens to focus light on the back of eye, also known as the retina making images to appear clear and without any distortion. When this lens becomes cloudy as a result of a cataract formation, it causes a distortion of vision. Cataracts appear in the normal and gradual aging process but can at times occur rapidly. When cataracts begin to affect vision, they can be removed through surgery. However, the decision to undertake cataracts surgery depends on the individual surgery and a doctor will be best placed to advise whether to proceed with the surgery or not.

What is cataract surgery?

Cataract surgery involves the removal of the eye’s natural lens after it has developed a cataract. During the surgery, the cloudy natural lens is removed and replaced with a synthetic one.

Candidates for cataracts surgery

For individuals with a significant loss of vision, surgery is recommended. However, it is not advisable to undergo a surgery if you have other eye diseases that are unrelated to cataracts but limits your vision. Sometimes, after undergoing a previous eye surgery or trauma to the eye, a cataract can make it difficult for the eye-care professional to see the retina. In such cases, it may be advisable to have the cataract removed so as to enable a further optic or retinal nerve evaluation and also to enable treatment to occur. The surgery mode can be tailor made to meet the need the coexisting medical condition of the patient. Minimal sedation is required for cataract surgery and the operation doesn’t take more than 30 minutes.

Cost of cataract surgery

There are many variables that affect the cost of cataract surgery. These include the type of procedure and the intraocular lens (IOL) to be implanted into the eye. The cost can also differ from one area to the other. However, the average cost of cataract surgery in the United States is around $3,429 per eye. But if you need a presbyopia-correcting intraocular lens for the cataract procedure, the cost will rise to an average of $4,269 per eye.

The good news is that most of those who require the surgery are covered by health insurance such as Medicare, as these aspects of the procedure are medically essential. When you feel as if you need the procedure, you should contact an eye-care professional.
