- Individuals with wholesome eyes who need to depend upon glasses and call lenses much less (maybe due to an lively or sport-oriented way of life)
- People who find themselves illiberal of glasses or contact lenses
- Individuals with prescription eyeglasses who nonetheless don’t get their finest imaginative and prescient

Laroche, additionally director of glaucoma providers and president of Superior Eyecare of New York, now not performs LASIK, concentrating totally on glaucoma remedy, together with surgical procedure. He warned that having LASIK can “give artificially low stress readings” throughout eye exams.
Hersh notes that in a small share of individuals, imaginative and prescient doesn’t enhance as a lot as they want after the surgical procedure, so they could have to have one other remedy, usually 3 to six months later to “tune it up, so to talk, to convey it from the 6-yard line to the 3-yard line.”
Dry eye and irritation are likely to get higher over time in most sufferers, though a handful go on to longer-term dry eye, Hersh notes. Sometimes, visible results like glare, halo, and hassle with night time driving ease quickly after the process; certainly, many sufferers have higher imaginative and prescient at night time than they did with their glasses or contact lenses. And LASIK gained’t forestall the necessity for studying glasses.
