Bad vision makes it hard to read traffic signals, giving many eyeglass-wearers backaches when they mistake Stop signs for Stoop signs. Genuflect in the presence of proper direction with today's Groupon: for $2,425, you get a CustomVue blade-free iLASIK vision-correction procedure on both eyes at Sudarshan Eye Experts (a $4,850 value). Pre- and postsurgery consultations and eye exams can be redeemed at either of Sudarshan Eye Experts' locations in Brownsville or Weslaco, but the surgery itself takes place at the Brownsville office. Clients must undergo the presurgery consultation by September 9, 2011 to make sure that they qualify for the treatment.

At Sudarshan Eye Experts, Dr. Alexander Sudarshan and his team of certified technicians aim to correct vision problems such as farsightedness, nearsightedness, and astigmatism through blade-free laser eye surgery. Once a preprocedure consultation determines that their baby blues are equipped to handle surgery, patients return to the office for comprehensive eye exams to ascertain their corneas' health and clock ocular 40-yard-dash times. During the surgery itself, lasers expertly reshape corneas in a humidity-controlled, air-conditioned chamber. 3-D ActiveTrak technology and a CustomVue light map helps ensure accuracy by instantaneously adjusting corrective lasers to minute, involuntary eye movements, such as those caused by breathing or tap-dancing eyebrows. At a follow-up appointment, the next day or soon after, doctors will check vision, eliminate eyedrops, and take other measures to ensure that brows remain free of eyeglass shackles.
