phototherapeutic การใช้

• An option for minimally invasive and long-term effective therapy is laser phototherapeutic keratectomy.
• Phototherapeutic keratectomy ( PTK ) can be used to excise or ablate the abnormal corneal tissue.
• It is also used in assessing the effectiveness of pharmacologic, behavioural, phototherapeutic or chronotherapeutic treatments for such disorders.
• Diseases that only affect the surface of the cornea can be treated with an operation called phototherapeutic keratectomy ( PTK ).
• Both of these parameters have been implicated in phototherapeutic effectiveness; further supporting the distinction between Type-I and Type-II mechanisms.
• Phototherapeutic keratectomy ( PTK ) using [ Excimer laser ] can restore and preserve useful visual function for a significant period of time in patients with anterior corneal dystrophies.
• Sulphonated benzochlorin derivatives demonstrated a reduced phototherapeutic response against murine leukemia L1210 cells " in vitro " and transplanted urothelial cell carcinoma in rats, whereas the tin ( IV ) metallated benzochlorins exhibited an increased photodynamic effect in the same tumour model.
