Is LASIK suitable for high myopia?

It is suitable for patients with high myopia (500-1000 degrees), astigmatism (up to 500 degrees), dry eyes and intolerance to contact lenses.

What is the maximum power of a myopic eye?

Mild myopia includes powers up to -3.00 dioptres (D). Moderate myopia, values of -3.00D to -6.00D. High myopia is usually myopia over -6.00D.

Will high myopia lead to blindness?

High myopia may raise your child’s risk of developing more serious sight conditions later in life, such as cataracts, detached retinas and glaucoma. Left untreated, high myopia complications can lead to blindness, so regular eye exams are critical.

Does myopia cause blindness?

Myopia, particularly high myopia, not only impacts your vision in the short term, but it can eventually lead to blindness. Studies across the world have shown that myopia can increase your risk of blindness through disorders like macular degeneration, retinal detachment, glaucoma, and cataracts.

Can monovision be used for IOL power calculations following LASIK or PRK?

Many patients opt for monovision as part of their laser vision correction strategy for LASIK or PRK. This works well in the setting of laser vision correction, but for IOL power calculations following LASIK or PRK, the level of accuracy required to achieve this may not be possible.

Can IOL power be calculated following keratorefractive surgery for myopia?

This section contains outlines of several popular IOL power calculation methods that can be used following the various ablative forms of keratorefractive surgery for myopia, such as LASIK and PRK.

Do the benefits of LASIK surgery justify the risks?

The possible benefits of LASIK surgery may not justify the risks. You have fairly good (overall) vision. If you see well enough to need contacts or glasses only part of the time, improvement from the surgery may not be worth the risks. You have age-related eye changes that cause you to have less clear vision (presbyopia).

How long after LASIK can I get my refractive error calculated?

Often, the calculations may be influenced our inability to determine the true post-LASIK refractive state (without the influence of lens-induced myopia). This is why for any of the historical methods that the post-LASIK refractive error is usually determined at four to six months after LASIK.
