Every eyelid surgery candidate should have a full ophthalmic exam prior to under going this rejuvenating procedure. As an Ocular Plastic Surgeon I examine and review several aspects of the patient's eyes prior to surgery. It may not be enough for your cosmetic surgeon to only look at your eyes at a distance. The eyelids and eyes must be checked for several conditions that could effect your happiness in regard to your surgical outcome. Your physician must check the height, contour, and muscle strength of the lids. For example if your eyelids do not fully close prior to the procedure or the lid is weak or "floppy" you may have problems with tearing or irritation after the surgery. The front of the eye, the cornea, must be healthy and this includes a good tear film. This can only be checked by a slit lamp exam. If your eyes are dry, you may still be able to have the procedure. If they are severely dry or you have corneal problems, you may end up with tearing problems. After eyelid surgery more air can hit off the eye worsening a dry eye or corneal problem. It is very important for patients who have had refractive surgery (LASIK) to have an ophthalmic evaluation prior and these patients are more prone to tearing problems. One of the most important tests is a Schirmer test which can be used to predict a dry eye problem. Ocular Plastic Surgeons check all of these factors prior to perfoming blepharoplasty.
