As anyone who has accidentally called a boss "mom" knows, being able to tell who's who is vital to the preservation of dignity. Put life into focus with today's Groupon: for $2,600 you get bilateral custom LASIK vision-correction surgery at Advanced Sight Center's Creve Coeur or Washington locations (a $5,200 value). Groupon buyers must schedule their initial evaluation within 45 days of their purchase.

The board-certified ophthalmologists of Advanced Sight Center can reduce or eliminate the need for glasses or contact lenses using LASIK eye surgery. LASIK changes the shape of the cornea to correct vision, and can restore or improve eyesight to 20/20 in patients suffering from nearsightedness, astigmatism, and some cases of farsightedness. Patients may schedule a procedure after an initial evaluation determines whether they are viable candidates. Once patients settle into the eye chair, doctors numb their peepers with a few drops of anesthetic, allowing the medication to take effect. Sight specialists then elevate a thin flap of the cornea, sculpt it into the correct shape, and place back it atop the eye using the Visx Star S4 laser. The procedure can cause mild pain and discomfort and takes approximately 30 minutes. After the procedure, patients should have a friend available to drive them home, as post-lazing eyes should not be taxed with life-and-death pothole-evasion maneuvers.

All patients receive a day-after follow-up exam, one-month follow-up exam, three-month follow-up exam, and any additional exams and laser treatments necessary for up to one year following the procedure. Appointments may be scheduled at either location, but all surgeries are performed at the Creve Coeur location. Patients should allow a few days after the procedure for recovery, and may not experience full results for three to six months following LASIK.
