I say get the eye surgery. Having suffered from poor eyesight my entire life, I would jump at the chance. My sister had such bad eyesight that she couldn't recognize people's faces at all unless she was wearing her glasses/contacts. She went to Canada in the early days of lasik surgery (before they were offering it in the US) and she had spectacular results. She went from 20/400 to 20/15 vision. 10 years later, she now has to wear reading glasses but she still doesn't regret it.
Final thought: If it was your husband or kids who needed the lasik, what would you say? Yeah, I thought so. Get the surgery.
But check prices, because like others have said, the $4k sounds a little high.
