Dry Eyes

Postby DeMa » Sun Jul 30, 2006 9:31 pm


I had LASIK surgery 1 & ½ years ago. I think I might need an enhancement. The reason I’m not sure is that I have extremely dry eyes (which is caused by the LASIK). Is it possible that my dry eyes are causing me not to see as clearly as I should be? I’ve even had plugs put in and that didn’t work. Not to mention, that I have tried all of the drops out there! It’s quite frustrating. If I went for an enhancement, would opening up the corneal flap make my eyes even drier? I also have poor night vision. Would getting an enhancement correct the night vision problem or would it make it worse?

Thank you,

Undoubtedly the dry eyes are the key to your vision problems. Chronic dry eyes can cause vision quality to be poor, can induce refractive error and increase the need for glasses, and can cause or exacerbate night vision problems.

We have a detailed article about Lasik Dry Eye Treatment that you should review. You will see that tears are about much more than just quantity. If you have a poor lipid layer, then punctal plugs will only marginally help and can even make things worse. If the artificial tears you use are not 100% preservative-free, they may be causing dry eye. Restasis is a prescription medication that has been shown in FDA clinical trials to resolve one of the underlying causes of dry eye. I recommend that you read the article and then visit a dry eye specialist.

If your dry eyes are caused by or exacerbated by the creation of the Lasik flap with your initial surgery, lifting the existing flap for enhancement surgery (if you actually need it) would likely restart the healing process – including restarting the dry eye issues. Surface ablation techniques tend to cause dry eye problems less often than Lasik and IntraLasik. If you do decide to have enhancement surgery, consider PRK or LASEK on the flap as an alternative lifting the flap for traditional Lasik enhancement surgery.

Depending on the root cause of your night vision problems, it is possible that the use of a wavefront-guided ablation will reduce or resolve those problems. Wavefront Lasik, PRK, or LASEK enhancement is normally possible, however you would need to have a detailed analysis to determine if you would benefit from this technology. Learn about Wavefront Lasik and talk to your doctor.

If the night vision problems and poor vision quality are simple refractive error (nearsighted or farsighted) then you may do well with contact lenses or even glasses.

You seem to have many options available to you, but which is best will depend upon totally upon the actual cause of your difficulties and your current refractive state. This can only be determined by a comprehensive examination from a competent doctor.
