Which eye surgery is the best to correct my vision?

Laser Eye Surgery Toronto

The holiday and the summer are usually a time when many people ask me about Laser eye surgery?

Should I do it?
Why do/don't you do it?
Which eye surgery is the best?
When is the best time to do it?

These are some of the frequently ask questions.
The most critical question is if you should do it? The other one is which procedure is the best?

The types of procedure out there today include PRK, LASIK, wavefront-guided LASIK, reLEX-SMILE, and ICL (implantable contact lens).

What is best is irrelevant in this case. What is best for you is a better question that can be addressed.
Aside from the few absolute contraindications such as glaucoma, retinal holes, keratoconus, there are relative contraindications or considerations such as your own eye power, amount of astigmatism, corneal thickness, keloid/scarring, amount of dry eyes, previous eye/lid surgeries, personality type, visual needs.

To find out if you are a good candidate, and which procedure is best for you, ask your local Optometrist for a refractive surgery consult. You would get an independent opinion on which procedure is best for your eyes, which equipment, and/or which surgeon might work best with you.

Why do my contacts make everything look bigger?

If you are myopic, or nearsighted, you would have been wearing minus (-) lenses. Those lenses minimizes the images you see out of them.

When you remove you glasses, or wear contact lenses, you would no longer see them minimized, so things look larger.

The opposite is true for Hyperopia or farsightedness, with plus(+) lenses.

You should adapt to them quite well, unless you switch between glasses and contact lenses too frequently.
When in doubt, call your local contact lens fitter or Optometrist for details.

We learned that good old Leonardo Da Vinci had mirror writing, with his left hand.
It's actually quite common for children under age 8 to have mirror writing too. It has to do with eye dominance.

Did you know that dyslexia is related to vision? Their eye dominance is usually developed by age 7-11 years old.. However, if it hasn't, then there is no differential treatment by the brain in picking the images out of both eyes past age 7. Find out more about dyslexia here.
