Will Blepharoplasty Affect my Previous Lasik Surgery?

In general, there are no major problems with blepharoplasty after lasik. However, dry eye syndrome is beleived to be more common, particularly after lower eyelid bleph following lasik. The usual recommendation is to wait 6 months.

There is a very small chance that your prescription can change ever so slightly after blepharoplasty and this is due to a change in tear film. If your eyes are dry, you want to be cautious after LASIK, because blepharoplasty too soon after can have this effect. If your eyes are well lubricated, then there shouldn't be a problem.

A question more commonly asked nowadays, but there are few scientific papers that address when it safe to proceed and what complications may be more prevalent if blepharoplasty is done too soon. If your eyes are "not dry" and your lasik surgeon gives you the go ahead, it is most likely safe to proceed. The actual blepharoplasty surgery will not affect the lasik surgery but the timing of such is important to avoid eye complications or side effects.

You should be fine. You just need to make sure that the surgeon and the anesthesiologist are both aware that you have had LASIK surgery, so they can take extra precaution to keep your eyes lubricated and protected.

Dear Tingmm,
Lasik causes dry eye by cutting the sensory nerves to the corneal surface when the flap is lifted. It takes time for this to resolve.
The eyelid surgery can also exacerbate dry eye. A properly done eyelid surgery will have a minimum impact on the dry eye situation. Having said that, you need a proper assessment of the condition of the eyes prior to eyelid surgery. If your cosmetic surgeon is not prepared to assess and manage the dry eye condition, you will need assessment by a general ophthalmologist which could be your refractive surgeon. The timing of the eyelid surgery should be deferred to whoever will be responsible for managing the eyes.
What it the worst that could happen is the closure of the eyelids could be compromised by the eyelid surgery in a setting where there is reduced corneal sensitivity following Lasik. This could lead to corneal break down after eyelid surgery. This can initiate a melting syndrome of the cornea, or a frank corneal ulcer which is a baterial infection. For these reasons, it is worth your while to take your time, and heal from the lasik prior to undertaking eyelid surgery and not proceed with eyelid surgery until cleared by your ophthalmologist.
