Which laser is commonly used in refractive surgery?

• A. CO2 Laser
• B. Excimer Laser
• C. Nd:YAG Laser
• D. Argon Laser

Answer: (B)

The Excimer Laser is the most commonly used laser in refractive surgery, particularly for procedures such as LASIK and PRK. This laser operates at a wavelength of 193 nanometers, which is well-suited for precisely reshaping the cornea. The main advantage of the Excimer Laser is its ability to remove corneal tissue in an accurate and controlled manner without damaging surrounding areas. This precision is essential for achieving the desired refractive correction while maintaining the integrity of the cornea. In contrast, the CO2 Laser, while effective for other surgical procedures, is not typically used in refractive surgery due to its inability to precisely target corneal tissue without causing thermal damage. The Nd:YAG Laser is primarily employed in procedures like posterior capsulotomy and laser iridotomy rather than for refractive correction. Similarly, the Argon Laser is used in treating retinal conditions and for other ophthalmic procedures but is not indicated for refractive surgery. Thus, the unique properties of the Excimer Laser make it an ideal choice for this specific application in ophthalmology.
