Emil William Chynn, MD, FACS, MBA · Answer

it depends on the type of lens, how you wear it, the fit, if you wear it overnight, etc

	so there are no hard rules, only very loose guidelines

	the real test if your corneal topography must be normal and unwarped before surgery

	sometimes this takes no time at all, sometime it takes months

	the very LOOSE rules-of-thumb are:

	soft contacts 1-2 weeks

	soft toric lenses 2-3 weeks

	extended wear lenses 2-3 weeks

	hard lenses 1-3 months

For people who wear soft contact lenses it is advice to be out of contacts for a minimum of one week. For those that wear hard contact lens, then the recommended time is at least 2 weeks.

Michael K. Tracy, MD · Answer

This really depends on the type of contact lenses you wear. 

	 

	Soft contacts should be discontinued two weeks before your exam and left out two weeks before surgery. 

	 

	Hard contact should be out for six weeks to six months before LASIK, depending on how long you have worn them. 

	 

	If your corneas look abnormal on the topographic scan, your doctor will want you to leave them out until your scan normalizes.

Ilan Cohen, MD · Answer

Contact lens wear should be stopped prior to laser vision correction because contact lenses themselves can alter the shape of the cornea. This can affect the measurments we take to correct the vision. How long you need to be out of the contacts depends on their material, shape and your wearing habits. The usual period is between 1 and 3 weeks but sometimes, particularly with hard lenses, it can be 6-8 weeks.

Anthony J. Kameen, MD (retired) · Answer

I prefer contact lenses to be removed approximately 10-14 days before Laser Vision Correction(Lasik or PRK). The reason for the time spread is that patients with a low level of astigmatism do not need to leave their lenses out for as long. Contact lenses can cause a very temporary "warpage" to the corneal surface, so the worse the astigmatism, the longer I like the lenses out, in order to uncover natural warpage rather than lens induced warpage. I see no reason to leave contacts out for a year before Lasik, unless there is some health issue with your cornea that makes this necessary.
