Is it better to over correct or under correct vision?

No benefits of over-correction of myopia was found. The overall findings are equivocal with under-correction causing a faster rate of myopia progression. There is no strong evidence of benefits from un-correction, monovision or over-correction. Hence, current clinical advice advocates for the full-correction of myopia.

Is Undercorrection good for myopia?

Overall, undercorrection of myopia may lead to the stimulation of eye elongation due to the presence of blurred vision at any distance and accelerate the progression of myopia.

Can LASIK under correction be fixed?

Correcting Lens Overcorrection & Undercorrection
