Introduction to LASIK Eye Surgery
Understanding LASIK
Laser-Assisted in Situ Keratomileusis (LASIK) is a popular refractive eye surgery designed to correct vision problems such as myopia, hyperopia, and astigmatism. By reshaping the cornea, LASIK improves the way light is focused on the retina, enhancing visual clarity.
History and Evolution of LASIK
The roots of LASIK date back to the 1950s with the development of keratomileusis. Over the decades, technological advancements have refined the procedure, making it safer and more effective. Today, LASIK is one of the most common elective surgeries worldwide.
How LASIK Eye Surgery Works
The LASIK Procedure
LASIK involves creating a thin flap in the cornea using a microkeratome or femtosecond laser. The surgeon then lifts the flap to access the corneal stroma and reshapes it with an excimer laser. The flap is then repositioned, and it naturally adheres without the need for stitches.
Technology Used in LASIK
Modern LASIK utilizes advanced technology such as wavefront-guided lasers and femtosecond lasers. These innovations allow for precise corneal reshaping and customization based on the patient’s unique eye structure.
Pre-Operative Steps
Before undergoing LASIK, patients must go through a thorough eye examination. This includes measuring corneal thickness, mapping the surface of the eye, and determining the degree of refractive error. These steps ensure the patient is a good candidate for the procedure.
Benefits of LASIK Eye Surgery
