Surgeries performed with laser beam techniques are much simpler than traditional procedures. Lasers are frequently retina. Lasers can also burn papillomas and excise pre-cancerous lesions from the mouth without scarring. Currently lasers are used to break down kidney stones and to open clogged arteries. 

LASER ANGIOPLASTY 

When fatty deposits accumulate in the arteries, plaque forms, and the internal channel for blood flow narrows. Laser angioplasty can be used to eliminate this plaque. In this operation, a catheter with a small balloon is used. The balloon is introduced into the artery and is inflated to momentarily cut off the circulation. The plaque is removed easily by a laser emitter located at the tip of the catheter. The Laser angioplasty is recommended when only one artery is blocked. The laser angioplasty operation is quick , and the patient's recovery period is usually short .

1. INCISION: An incision is made in an arm or leg or in an artery. The catheter is introduced. Guided by X-rays or ultrasound, it is directed towards the location of the blocked artery.
2. LOCATION: The catheter is directed towards the location of the blockage. The balloon is inflated, and it presses against the arterial walls. Blood circulation is temporarily cut off to permit the removal of plaque.
3. DESTRUCTION: From the tip of the catheter, the laser emitter applies a beam directly on the atheromas of the artery. The fragments of plaque are removed through a vacuum mechanism.
4. CONTROL: Once the process of destroying the plaque is finished, the blood pressure is checked on both sides of the arterial wall to ensure that it is equal. The catheter with the balloon is then removed. The recovery period is short; the patient only needs a brief post-operative rest period.

LASIK SURGERY

The procedure is very simple and takes only 15 minutes. The cornea is shaped so that images will be more precisely focused on the retina. The cornea's structure is modified depending on the condition being corrected.

1. LOCAL ANESTHETIC: An anesthetic is applied to the eye in the form of drops to allow the eye to remain open.
2. EXTERNAL LAMELLA: A small cut is made on the cornea. A very thin flap is lifted where the laser beam will enter.
3. LASER BEAM: In only five minutes, the centre of the cornea is shaped by the laser beam, which is controlled by a computer.
4. FINAL STEP: The flap is returned to its original location. It adheres to the cornea without the need for stitches. The patient is able to walk out of the operating room.
