Elective eye surgery, also known as LASIK (an acronym for Laser-Assisted in Situ Keratomileusis), is a type of refractive surgery that uses laser technology to reshape the cornea and correct vision problems such as nearsightedness, farsightedness, and astigmatism. It is a safe and effective procedure that can be used to improve vision without the need for glasses or contact lenses. The procedure is usually done on an outpatient basis and takes only a few minutes to complete. Patients typically experience improved vision within a few days after the procedure.
