Will LASIK be able to fully correct astigmatism?

Doctor's Answers 2

Yes, LASIK can correct astigmatism, as well as myopia (shortsightedness) and hyperopia (longsightedness).

It can correct any of these problems fully, within certain limits.

For example, the maximum shortsightedness that can be corrected is around 1000 degrees, depending on corneal thickness. With astigmatism, the maximum is lower, around about 400-450 degrees or so.

Bear in mind that any refractive surgery has a risk of under or over correction, although in most cases, the final result will be very close ie within +/- 50 degrees or so from the target.

Modern Lasik platforms are highly effective in treating all forms of refractive error (myopia, hyperopia), and especially up to -5 to -6 dioptres of astigmatism.

It is important to have a thorough and comprehensive evaluation by your trusted ophthalmologist, as it is important to establish whether other eye conditions that may result in progressive astigmatism are excluded prior to considering any laser surgery.

For progressive corneal conditions, patients may also consider an adjunctive corneal collagen cross-linking procedure during the laser procedure.

For high levels of astigmatism that may not be fully corrected with Lasik, patients also consider an implantable collamer lens as a refractive treatment option.

Best of luck!

Does LASIK enhancement for hyperopia require a longer recovery period?

Hi, generally speaking, it is quite common to have some amount of haziness of vision in the early period after laser procedures, although this is usually least for LASIK as compared to other procedures like epiLASIK/PRK or even SMILE. Also, usually there is no/minimal difference whether it is LASIK enhancement for myopia or hyperopia. I would agree with Dr Chan that it is difficult to advise further unless we have further information and have a chance to examine your eyes.

What is the effect of LASIK on strabismus (cross-eyed)?

Thanks very much for your enquiry. Generally speaking, I would advise LASIK before any squint/strabismus surgery. This is because there is a risk that changing the spectacle power of the eye (via LASIK) may make the intermittent exotropia more obvious if a patient finds it harder to ‘fuse ‘ the images from each eye after LASIK. If so, the strabismus surgery can then address the full effect and magnitude of the squint. Ideally, if strabismus surgery is required, it would be performed at least a month after LASIK surgery when the vision and spectacle power has usually stabilized.
