What is the number one reason that patients decide to have LASIK?  Why do patients come in and see their eye doctors the most?

Usually is it the most common vision symptom – what many term ‘blurry vision’.

What is Blurry vision and what causes it?

Blurry vision is defined as a decrease in sharpness or a lessening of the clarity in vision which usually develops on a gradual basis.

Blurry vision can be caused by disorders of the retina, clouding of your cornea, lens or vitreous humor, disorders affecting pathways of nerves (like the optic nerve) that go to your brain, or the MOST common cause which we call: “refractive errors”.

Refractive errors are essentially when rays of light are imperfectly focused on your retina. These refractive errors are called nearsightedness, farsightedness or astigmatism.

There are some rare disorders that also cause blurry vision but those include inherited disorders which affect our optic nerves or corneal scarring. Read more here.

When is blurry vision ‘concerning’?

  • If you have eye pain
  • If you notice a sudden change in your vision
  • If you notice a loss of a specific area in your vision (what we call a ‘visual field defect’)
  • Your vision is reduced severely in one eye
  • You have any condition which affects your immune system (for example if you are using medication that is immune-suppressing or chemotherapy)

What happens if you have blurry vision?

Go see an eye doctor!

You can see either an ophthalmologist or an optometrist. Read more about the difference between the two here.

They will perform testing and an eye examination which will determine the cause, and if you have a refractive error, will determine which one – then will provide you options for treatment.

How will blurry vision be treated?

Depends on the patient!  There are glasses or contact lenses – and then there is refractive surgery like LASIK which we are happy to share more about HERE.

There are more ‘refractive’ surgery options now – like the ICL and Refractive Lens Exchange (“RLE”) and we would be more than happy to see you and share all of the options out there with you. Our specialists will guide you on the best option for your vision, age and lifestyle.
