Lasik is getting very popular lately to correct for refractive lens problems such as short sightedness, long sightedness and astigmatism. However, before you join the crowd blindly and go for Lasik, weigh the pros and cons first. This is called taking an informed decision. Understanding the basics of Lasik will enable you to choose the best options to correct your eye sight.
You have a natural pair of lens in your eyes that you are born with. Those of you who are fortunate will have very little problems with this set of natural lens. However, some of you may have defective lens, causing blurred images to be received by your eyes. These blur images resulted because the light reflected from external images cannot be focused correctly on your retina. Short sightedness and long sightedness are due to under or over focus of the images on your retina, while astigmatism is due to uneven focusing of images on your retina.
Lasik can help to repair the focusing of images with your natural lens, as it uses laser that can target specific tissues or muscles very precisely for repair. However, Lasik, being an artificial means, also brings with it a certain amount of risks and costs for the procedures, and pre and post consultations. I used to wear eye glasses for short sightedness, but have threw away my glasses several years ago. No, I did not go for Lasik, but instead opted for low cost, safe and natural means to improve my eye sight.
I now have perfect vision in my right eye, and near perfect in my left. I have searched for natural ways to improve my vision, and have found one that actually works for me. Do check out the scientifically proven, natural and easy way to improve your vision, without burning a hole in your pocket. Go to the website http://health11.info for more information.

Cataract is the clouding of the lens of the eyes. It affects vision. A thin lining of cloudy natural lens is removed from the eye because it blocks the passage of light. This is how a cataract surgery is done. Cataract surgery is a harmless procedure. Every year, there are more than 1.6 Americans who undergo this treatment to repair their vision. More than half of the American population have cataract or may have been through a cataract surgery by the age of 80. Some people believe that when one eye has cataract, the other eye will definitely be next. This is a myth. Cataract doesn’t spread. It can occur in either or both eyes though.

On the day of the surgery itself, there is a list of things to do such skipping breakfast and avoiding intake of liquids. An eye drop to dilate pupils and sedative are given prior to the actual procedure. Topical anesthesia is also given in order for the patient not to feel the pain. After the areas around the eyes were completely cleansed and after a sterile covering is put into place, at least a small cut is done into the eye to enable the surgeon to remove the cloudy lens. There are two methods to remove the cloudy lens. One is through sonically breaking up the cataract then extracted out of the eye. The other one is through mechanically breaking up the cataract into small pieces then removed from the eye through a small incision. After this, a plastic or silicon intraocular lens will replace the natural lens that was taken off the eye.
After the operation, a protective shield is placed on the eye. Then the patient is usually sent home after few minutes in the recovery room. Surgeons advise patients to apply eye drops for a number of times in a day. This goes on for few weeks depending on the surgeon’s advice. Just like any other medical procedure, there are dos and don’ts patients are given to ensure effectiveness of the operation.
The price of a cataract surgery is around $3,000, exclusive of health insurance. Fortunately, HMOs, Medicare and other health insurances cover this specific surgery. It is indeed pricey however, the American Society of Cataract and Refractive Surgery reports 98% of the patients believe it is highly recommended since it simply worked for them.

Cataract is a malfunction of the human lens. It actually is an opacity or cloudiness of the natural lens inside the eye. Cataract comes often – but not exclusively – with old age, and it’s very common among old people.
The amount of lens opacity is influenced by various factors and differs from person to person. Most people who suffer from cataract have it in both eyes, but it’s also possible to have it in one eye only.
Cataract is not contagious from one eye to the other, or between persons, and once it is removed completely, it will not come back. Cataract can start very mild, and there’s a huge difference between people in how fast it progresses. If cataract comes with old age, it can progress through years, while in traumatic cataracts, it can mature in days or even hours.
Cataract Symptoms
The most common symptoms of developing cataracts are:
1. Cloudy or blurred vision that gradually gets worse over time. There shouldn’t be any pain associated with your blurred vision. Eyes that are painful and red are more likely to be effected by glaucoma rather than cataracts. You should see a doctor immediately if there is sudden and complete loss of vision.
Young people are more likely to notice the blurring, even if they only have mild cataract symptoms. Older people are less likely to report blurred vision even if their cataracts are more advanced. Distance vision is usually more blurred than near vision. As a cataract thickens, even reading vision can start to get blurry.
2. Lower contrast between colors.
3. Increased levels of glare when you are faced with bright sunlight, or headlights during night time driving.
4. You may start to see a halo around lights, even during the daytime.
5. Night vision will start to decrease and you will have trouble seeing when it is dark.
6. Double vision can occur when cataract occurs in one eye(also referred to as monocular double vision). If you cover one eye, you will still have double vision. This is one symptom that may actually disappear as the cataracts get worse.
7. If you wear prescription glasses, you might find that they need to be changed frequently as the refractive power of your eyes changes.
8. One unusual symptom is that your near vision may actually improve and become clearer without the use of prescription glasses. This phenomenon is called “second sight”.
Though these symptoms may all point to possible cataracts, they can also indicate other potential eye problems. If you experience any of these above symptoms, you should make an appointment with an eye care professional as soon as possible.
