Final answer:
Laser skin resurfacing works by using an excimer laser to precisely remove skin layers. This technique harnesses the excimer laser's ability to emit a well-focused, single-wavelength light that is strongly absorbed by skin tissue, enabling accurate and effective improvements in the texture and appearance of the skin.
Step-by-step explanation:
Laser skin resurfacing is a medical procedure that uses lasers to improve skin texture and appearance. The process involves the use of a laser to remove layers of skin with precision. During the procedure, a specialized excimer laser emits bursts of ultraviolet radiation, which is strongly absorbed by the corneal tissue, allowing for precise ablation—or vaporization—of the tissue. This method of using a pure, well-focused single wavelength of light allows for extremely accurate removal of tissue, which is essential for correcting vision issues such as nearsightedness, farsightedness, and astigmatism.
In this procedure, a computer-controlled program delivers a series of rapid bursts to selectively remove tissue at the microscopic level. The laser ablation process reshapes the cornea based on a detailed assessment of the patient's vision, resulting in improved vision for the majority of patients. The selective absorption of the laser wavelength and precise focusing enables accurate and effective treatment, leading to rapid and nearly painless healing.
