Tightening the Outer Corners of the Eyes with Blepharoplasty?

The eye shape can and should be addressed when a lower blepharoplasty is performed.
Often, the problem occurs during a first blepharoplasty, when skin is removed from the lower eyelid. This causes pulling down of the eyelid and rounding of the eye. In some patients, theyr eyeball (globe) is prominent, and protrudes out of the bony socket. Both of these conditions can cause dry eye by too much rounding of the eye and too much exposure of the very sensitive cornea, the lining of the eyeball.
When the corners of the eye are corrected, a canthopexy or canthoplasty can be performed. In our practice, we almost always combine this with a cheeklift (LUSIC cheeklift), in order to "give" tissue to the lower eyelid so that can then be used to be reconstruct the corner of the eye.
The eye can change in shape, almost always for the better. Most patients prefer the unoperated appearance of an almond shaped eye to the rounded, operated appearing eye.
The lower eyelid is one of the trickiest areas in all of plastic surgery, and the patient should do their research carefully before undertaking the procedure. The highest incidence of unfavorable results in all of eyelid surgery occurs in patients with prominent globes.
There are several publications on this topic on our website drbrent.com for patients interested in the fine details.

A blepharoplasty procedure can be performed successfully during a facelift procedure.
In the case of a patient with dry eyes, a plastic surgeon should be cautious of exacerbating the dry eyes by revisional surgery on the upper or lower eyelid. A thorough analysis of the causes of dry eyes is appropriate, with examination of the cornea, tear output, and lacrimal gland function.
A canthoplasty can also be performed during a blepharoplasty procedure to tighten the lower eyelid to prevent further exposure of the lower eyelid. However, this will help based on the identification of the causes of the dry eyes.
In your case, I would perform a complete eye examination and also have a referral to a corneal specialist who would examine the lacrimal gland function. These tests, in addition to an anatomic examination will allow a thorough plan to minimize further injury to your eyes.

Thanks for your questions Page -
In my practice, we perform upper and lower blepharoplasty, and a careful history about dry eye must be obtained. The issue is that blepharoplasty can make eye dryness worse and interfere with your ability to protect your eyes, causing complications that can be as serious as blindness.
The fact that you note you have some prominent globes increases possible complications.
For patients with multiple risk factors, we typically employ several tests to determine the severity of your issues. These tests look at the anatomy and elasticity of your lids, your ability to protect your cornea, and the quality of the lubrication of your eyes.
It sounds like your surgeon has recommended a canthopexy to tighten your lower lid. This can help with some of these problems. The cathopexy can have an impact on cosmetic result, but when done properly, this can be part of improving the overall look.
Proceed with caution and make sure to discuss these issues in depth with your surgeon.
Be sure to be dealing with a board certified plastic surgeon in this situation.
I hope this helps!
