Refractive surgery is a type of eye surgery designed to correct vision problems by reshaping the cornea, the transparent front part of the eye. The goal is to improve how light is focused onto the retina, reducing or eliminating the need for corrective lenses. Common refractive surgeries include:

• LASIK (Laser-Assisted In Situ Keratomileusis): Uses a laser to reshape the cornea after creating a thin flap.
• PRK (Photorefractive Keratectomy): Reshapes the cornea using a laser, but does not involve creating a flap.
• SMILE (Small Incision Lenticule Extraction): Involves removing a small, lens-shaped piece of corneal tissue through a tiny incision.

These procedures are typically used to correct conditions like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
