Is It Possible to Achieve a More Deep-set Eyes?

Dear Smilebaby
This is an unusual concern that you are describing. It is the nature of the world we live in that you may find someone who will try to do whatever you ask. However, you need to be carefully assessed to determine if what you are considering makes sense. Orbital decompression with fat and bone remove is used to set the eyes back into the orbit when thyroid eye disease pushes the eyes forward. However, it is much less common to use these surgeries to perform "comsetic' orbital decompressions for the purpose of moving the eyes back.
My best advise is to seek several opinions for expert ophthalmic plastic surgeons. These are board certified ophthalmologists with specialized training in eyelid and orbital plastic surgery.
The American Society for Ophthalmic Plastic and Reconstructive Surgery maintains a directory that will help you located a quailified doctor near where you live: www.ASOPRS.org.

When patients are noted to have prominent eyes, they should be evaluated for both congenital and medical conditions. Medical conditions such as hyperthyroidism can cause prominent globes, while congenital conditions can cause the boney orbits to be small. Both conditions can make the eyes protrude in an outward direction.The vast majority of patients with slight eye prominence fall into normal range. The vast majority of these patients aren't bothered by the appearance of their eyes.Rarely, patients request treatment of this condition. Under these circumstances, it's possible to make the eyes more deep set by performing an operation known as an orbital decompression procedure. Unfortunately, this procedure is complicated and has a poor risk benefit ratio and for this reason, is only rarely utilized unless severe deformities are present.When patients are concerned about prominent eyes, it's important that they be evaluated by a board certified plastic surgeon. This surgeon should be able to formulate a treatment plan that addresses their anatomic findings and aesthetic goals.

Orbital decompression is the name of the procedure done to achieve what you're describing. But it's an operation reserved for significant eye problems from diseases such as Graves' ophthalmopathy. A frequent side-effect of such decompression surgery is diplopia--double vision--which has to be subsequently corrected by additional surgery on the eye muscles.
From a cosmetic standpoint, the risks don't justify the procedure.
All the best,

The eyeballs cannot be made more deep-set into the orbit of the face. Fat pads when present on the lower lids can make the area look puffy, these can be removed to create the illusion of a more inset eyelid. However, the puffiness has to be present first prior to removing any of that lower orbital fat.

Smilebaby,
Bulging eyes or exophthalmos can be caused by metabolic/endocrine conditions such as hyperthyroidism. Start with a visit to your internist for some simple blood tests to rule out these conditions. Then, you might want to see a board certified plastic surgeon for options to correct your eye appearance. Good luck!
