While both procedures interact with the epithelium atop the cornea, the PRK procedure removes this entirely, while LASEK brushes the material away for the procedure, before being placed back for healing after laser surgery. [2] The procedure can be used to treat astigmatism, nearsightedness, and farsightedness. [3]
Recovery time is longer with PRK than with LASIK, though the outcome (after 3 months) is about the same (very good). More recently, customized ablation has been performed with LASIK, LASEK, and PRK. Transepithelial photorefractive keratectomy (TransPRK) is a laser-assisted eye surgery to correct refraction errors of human eye corneas. It uses ...
CO 2 lasers are both efficient at cutting and coagulating. [4] Laser surgery is commonly used on the eye. Techniques used include LASIK, which is used to correct near and far-sightedness in vision, and photorefractive keratectomy, a procedure which permanently reshapes the cornea using an excimer laser to remove a small amount of the human tissue.
Results of lingual frenectomia via laser surgery have been thought to be superior to those of traditional cold steel methods, however, minimal evidence exists. The skill of the provider is most important in the success of this procedure. It is unknown if laser frenectomy results in a lower risk of relapse (i.e. adhesion). [2]
Fat removal procedures are used mostly in cosmetic surgery with the intention of removing unwanted adipose tissue. The procedure may be invasive, as with liposuction , [ 1 ] or noninvasive using laser therapy , radiofrequency , ultrasound or cold ( cryoablation or cryolipolysis) to reduce fat, sometimes in combination with injections.
Buccal fat pad extraction or buccal fat removal is a plastic surgery procedure that removes a piece of buccal fat-pad tissue from each side of the face. This reduces the appearance of cheek puffiness, creating a sharper jawline. The amount of fat removed varies based on the desired facial shape. [1] It is a strictly cosmetic surgery. [2]
