How Laser Eye Surgery Works
Laser Eye Surgery is a means of vision correction where lasers are used to produce precise pulses of UV light energy. These pulses are delivered accurately onto the cornea by our laser eye surgeon.
This energy weakens the bonds between atoms in the cornea. It enables the microscopic amounts of tissue to be removed in a process called Cool Ablation.
Since little to no heat is produced during Laser Eye Surgery, no damage is done to the adjacent tissue. It allows the computer-guided laser to generate a new corneal profile by sweeping back and forth across the eye. It allows for an accurate focus of light on the retina for improved vision.
For nearsighted people, the goal in laser eye surgery is to flatten the Cornea; with farsighted people, a steeper Cornea is desired. Excimer lasers can also correct astigmatism by smoothing an irregular cornea into a more normal shape.
This reshaping can be done on the front surface of the eye by gently removing a thin layer of cells. This procedure is called LASEK. Or it’s done by first forming a flap in the Cornea, a procedure called LASIK.
In LASIK the flap is carefully repositioned before a bandage lens is placed. It usually takes a few days for your eye to settle. You will need to use eye drops for a few weeks after your treatment.
Every person and every eye is unique. Your consultant will provide you with more detailed information about your particular condition.
