More than 80% of the people undergoing the laser surgery are satisfied with the results of the surgery. However, there are some laser eye surgery risks, which the person willing to undergo a laser surgery should be aware of. You should consult your eye specialist before taking this important decision. Ocular surgery is another way for laser eye surgery. Opthalmologists carry out this surgery on the adnexa of the eye of the patient. Every patient willing to undergo the laser eye surgery is recommended to be fully aware of the laser eye surgery risks and benefits.

Types of Eye Surgeries
Photo refractive keratectomy or PRK and LASIK are the two main types of vision correction surgeries, which are performed over patients with eye related disorders. The LASIK is a type of refractive eye surgery. This eye surgery is sometimes also written as Lasik. The main purpose of the LASIK surgery is to help the patients recover from eye related disorders such as hyperopia, astigmatism and myopia. The photorefractive keratectomy can also be called as the advanced surface ablation. The LASIK surgery type is always preferred over photorefractive keratectomy or PRK because, after the surgery is over, the patient recovers faster than the PRK surgery. To add to this, the pain caused to the patient during the LASIK surgery is much less than the PRK type. People who do not like to wear spectacles or contact lenses should go for the Lasik surgery. However, the PRK is also a widely used eye surgery.

Benefits of Laser Surgery
There are many laser eye surgery benefits. Laser surgery is like a one time investment. Once you recover completely from it, you can save a lot of money on eye examinations, buying contact lenses and eye solutions and drops. You would not require to wear your spectacles all the time. Maintaining contact lenses is a big issue for many people. You can get a permanent relief from all the contact lens related eye problems.

Many people who undergo the laser eye surgery experience dryness in their eyes. Dry eyes after Lasik eye surgery is due to the reduced capacity of the eyes to produce tears due to the damaging of the corneal nerves. The tears produced by the eyes help to keep the eyes moist. This side effect of the laser surgery may or may not be permanent. Due to this dryness in the eyes, the ability of the eyes to see things properly decreases. Laser surgeries in certain people have led to a serious condition known as corneal ectasia.

Corneal ectasia is characterized by the presence of a fluid build-up in the eye which underwent the laser surgery. If this kind of complications arise, then eye surgeons usually recommend the corneal transplant operation. The possibility of a vision loss due to the laser surgeries also cannot be ruled out. The issues like blurred vision, possibility of developing a double vision are also common side effects of this surgery. Some people face problems while viewing things or driving at night. The patients need to be very careful and take precautionary measures to avoid infections after the surgery. Some patients do complain that their earlier vision was better than the vision after surgery. This question raises doubts about the effectiveness of the laser surgery. Retinal detachment and cornea problems also follow after laser surgery in some cases. The above mentioned laser eye surgery risks are not applicable for each and every individual. Researchers over the world are studying the laser eye surgery risks and benefits to discover better options for patients.

In his respect, deuternopia, a kind of shade loss of sight is referred to as daltonism. In most of the situations, shade loss of sight is genetic. An children gets this problem from his or her mother. The great majority of the genetics responsible for along with perspective are located on the X-chromosomes. A inherited problem may affect the 3 kinds of the spool tissues that definitely finds different colors in the noticeable light and imparts along with perspective to a individual. In women, the sex chromosomes are XX and the men have XY pair. This is why shade loss of sight impacts men more than it does to the women. The spool tissues are discovered in the retina of sight. One kind of the spool tissues get sensitive when light of short wave length drops on them, the second kind gets thrilled when they sign-up light of method wave length and the third kind of spool tissues can sign-up light of long wavelengths. This capability of the spool tissues enable us to see red, natural and blue colors and their colors. If a individual is lacking in one or all of these spool tissues, it makes him shade sightless.

Symptoms of Color Blindness
The harshness of shade loss of sight relies on the amount of spool tissues that are missing in the retina of the eye. In some situations, shade loss of sight is so light that the patient may not even know about it. However, a individual seriously suffering from this difficulty may encounter following signs of shade blindness:
He may encounter trouble seeing colors. He may also fail to sign-up their lighting.
