LASIK

LASIK (an acronym for Laser-Assisted In Situ Keratomileusis) is a type of refractive eye surgery used to correct myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. It is a widely-used surgical procedure with the goal of reducing dependency on glasses or contact lenses.

Procedure

LASIK involves reshaping the cornea, the clear front part of the eye, using a laser to allow light entering the eye to be properly focused onto the retina for improved vision. The surgery consists of creating a thin flap on the eye, folding it to enable remodeling of the tissue beneath with a laser, and then repositioning the flap.

Risks and Complications

While LASIK is generally safe and effective, potential complications can arise, including dry eyes, glare, seeing halos around lights, and difficulty driving at night. In rare cases, loss of vision can occur.

Contraindications

Not everyone is a good candidate for LASIK. Contraindications may include corneas that are too thin or irregular, severe dry eye, conditions that affect wound healing such as autoimmune diseases, and unstable vision prescription.

Aftercare

Postoperative care for LASIK typically includes using eye drops to prevent infection and inflammation, and avoiding activities that might harm the eye while it is healing, such as contact sports or swimming.
