What is the Range for Laser Vision Correction
The absolute range for correction of nearsightedness, astigmatism and farsightedness goes from about -14.00 to +6.00, so, technically, at +5.50, this patient may be a candidate. The more important question is what is the thickness of the cornea and the "shape" of the cornea, before we perform LASIK. Obviously, this question can only be answered after a thorough eye examination and consultation. At my office in Maryland, we do not charge for this visit.

LASIK for high plus corrections
Hyperopic (or farsighted) LASIK surgery can be done for corrections up to +6 diopters with most advanced lasers. It IS FDA approved for these high corrections. However, most experienced surgeons have seen best results up to +4D or so, with results between +4 and +6D being good but not as good.
For higher corrections, there is a higher risk of night glare/halos, increased risk of subtle loss of best corrected visual acuity, and a higher risk of needing a touchup surgery. Also, for people...

Of course it is necessary to otherwise be a good candidate for these procedures, and not everyone is capable of having this programmed into the laser for their particular eyes.
Assuming that the shape of the eyes is symmetric and normal on scans and...

Range of LASIK vs LASEK
The most you can usually safely treat with LASIK without cutting too deep and going too deep into the cornea, and violating too much tissue, and causing iatrogenic keratoconus, is about -9 or -10. Maybe -11 if you start out with thick corneas, and don't do CustomVue as that takes away more tissue when you laser compared to the older standard non-custom procedure.
With LASEK, which is a much more advanced version of the older PRK that was the initial laser procedure that was...
