Can you get LASIK with corneal scar?

James Aquavella, MD, a professor in the department of ophthalmology at the University of Rochester, cautions that LASIK should not be performed if the scar is central, as visual acuity would remain affected following the procedure.

Does LASIK reshape the cornea?

During LASIK eye surgery, an eye surgeon creates a flap in the cornea (A) — the transparent, dome-shaped surface of the eye that accounts for a large part of the eye’s bending or refracting power. Then the surgeon uses a laser (B) to reshape the cornea, which corrects the refraction problems in the eye (C).

What kind of eye problems can LASIK solve?

According to the National Eye Institute over half of all Americans experience a refractive error that can be corrected. LASIK, or other forms of vision correction surgery can improve the most common types of refractive errors including myopia (nearsightedness), hyperopia (farsightedness), astigmatism and presbyopia.

How do you treat higher order aberrations?

Certain types of new wavefront designed glasses, contact lenses, intraocular lens implants, and wavefront-guided laser vision correction can correct higher-order aberrations.

Does LASIK permanently fix eyes?

How Permanent Is LASIK? “LASIK surgery is permanent, with a few exceptions,” ophthalmologist and Manhattan Eye director Yuna Rapoport, MD, tells WebMD Connect to Care. “There is a chance that the prescription and correction can regress, and the vision regresses slightly back to what it was before.

Can LASIK fix optic nerve damage?

The procedure reshapes the outer layer of the eye (cornea) to improve vision. Because LASIK improves the cornea on the outer layer of the eye and glaucoma affects the optic nerve in the eye, LASIK cannot improve the condition.

Can higher order aberrations be fixed?

Higher-order aberrations (HOAs) are more subtle and complex refractive errors than nearsightedness, farsightedness and astigmatism. Because of their complex nature, these aberrations cannot be corrected with regular eyeglasses and most contact lenses.

Is it possible to eliminate all aberrations?

Currently, all that can be accomplished is the projection of a single plane onto another plane; but even in this, aberrations always occurs and it may be unlikely that these will ever be entirely corrected.
