Blepharoplasty is the surgery that seeks to rejuvenate the eyelids by remodeling the periocular tissues. It is performed mainly for aesthetic reasons, but in some cases also for visual reasons (functional blepharoplasty) since the skin drop of the upper eyelids can cause a reduction of the visual field.
The cosmetic surgery of the eyelids can be performed in adults of all ages and in both genders. Some patients undergo surgery to correct problems of laxity of the skin or blepharochalasis even at an early age such as 20 or 30 years.
The aging process causes several changes in the periocular area. In the upper eyelid are characterized by an excess and fall of the skin of the eyelid, which causes an aesthetic alteration but, in some cases, also causes an alteration of the visual field of the patient and ocular fatigue due to the weight that the excess of skin represents for the eyelid. This is a condition called dermatochalasis. Another condition associated with aging is the presence of a palpebral ptosis caused by laxity of the fibers of the elevator palpebrae superior muscle.

In the lower eyelid, the laxity of the fibro tendinous structures that appear with age causes two fundamental changes at the eyelid level. On the one hand, the orbital fat, which occupies a large part of the orbit, is herniated forward, becoming visible on the skin and giving rise to the known "bags". Secondly, the stretching and flaccidity of the skin, orbicular muscle and tendons of the eyelids give rise to wrinkles, folds and a lower eyelid descent and droopiness of the lower eyelids, showing white below the iris (colored portion of the eye). 
Likewise, palpebral positions such as ectropion, which in turn would produce an alteration in the drainage of the tear, can also occur in association with aging.
Aesthetic eyelid surgery can usually correct these problems, though other treatments may also need to be considered. For example, if the upper eyelid condition is accompanied by sagging of the eyebrows.
The upper and lower Blepharoplasty procedure was made during 25 years with the Novalupse CO2 laser in the cut mode at 5 or 6 WATTS, either with the titanium tip or with the diamond blade and the CO2 laser. The technique allows us to remove excess skin, fat and sometimes muscle, without bleeding, making the procedure faster and without residual bruises for the patient.
Because of individual factors, not everyone will achieve the same results from eyelid surgery. The surgeon will choose the most appropriate technique for each patient. As an example, we have performed different variants of the same technique in over 2000 patients. Most of them from Latin-American origin and wanting to correct some degree of ptosis, laxity of skin, blepharochalasis, dark eye, etc.
