LASIK eye Surgery
LASIK eye surgery are often used to correct refraction error to the retina. When experiencing spherical refraction errors (commonly referred to as near or far sighted) properly focused into the retina making images blurry. When experiencing cylindrical refraction errors the lens in the eyes are bent like the side of a cylinder instead of a sphere. This can cause Astigmatism where light coming at different angles have different level of clarity, and Presbyopia where light from close objects are blurred because of reduced flexibility of the lens usually caused by aging. In a LASIK eye surgery, a laser cuts a section on the top of cornea to create a flap. Then a laser is used to reshape the cornea by vaporizing some of the tissue until the desired shape is created and the error is able to be corrected. The flap is folded back and healed on to the eye. |
Selective Laser Trabeculoplasty
Selective Laser Trabeculoplasty is used to treat glaucoma which is a disease that affects the optical nerves of the eye, where the pressure is too high in the eye because of poor fluid drainage. Glaucoma can lead to blindness, it is usually treated with medication like drugs, but may resort to surgery in severe cases. In a Selective Laser Trabeculoplasty, a low powered laser is beamed on the tissues responsible for drainage in the eye, improving fluid flow and reduce the pressure.

Retina Tears or Holes
In some cases the Retina that is responsible for sensing light, may have tears or holes, this can lead to leakage of eye fluid and blood as well as abnormal growth of blood vessel. A thermal laser can be used to seal the leak.
Diabetic retinopathy
Diabetic Retinopathy is the loss of vision from the result of diabetes, diabetes may cause abnormal blood vessel growth and leakage in the eye. A thermal laser is used to seal leakages and vaporizes abnormal growth.

Cancer Treatments
Treating cancer with laser is know as laser therapy, a high powered laser is directed on to a tumor to shrink or destroy the tumor. Laser surgery is used only to treat superficial cancer which are on the surface of the body or organ. Usually, laser therapy uses Carbon dioxide or Argon as mediums. The method is to vaporize or cut the tumor or growth, if directed at areas inside the body, a flexible endoscope is used.
Endovascular Surgery
When arteries are blocked with plaque, it can lead to heart attacks and blockages which may be fatal. Using a laser contained in a catheter, the plaque is removed by precise movement of high powered lasers.

Cosmetics
In addition to treating diseases, lasers can also be used in cosmetics specifically scar removal where a laser melts the scar and removes the marking and laser hair removal where hair follicles are destroyed by exposure to laser to remove unwanted hair growth permanently.

Pros and Cons of Laser surgery
Laser surgery has brought us many benefit, mainly as a method to treat various diseases many of which are difficult to treat without lasers specifically eye diseases. Laser surgery are more beneficial than normal surgery because they are more precise, they cause less pain, bleeding, swelling, scarring and infection versus normal surgery, lastly they take much less time to heal after the procedure.
As much benefits the laser surgery has, it also has many disadvantages. Laser surgery requires extensive treatment and heavy equipment that are both much costly compared to the common surgery. Laser surgery may also require repeated treatments.
In the future laser surgery can perform operations on places that regular surgery cannot reach or is difficult to operate such as the brain. As people gain more knowledge of lasers, we can create light sensitive drugs that can be activated by lasers to get to hard to reach area and specific tissues. Overall the application of lasers can cure many disease and holds much more remedies.
