This review provides information about MyoRing treatment of keratoconus (KC). MyoRing is a complete ring implant that is inserted into the cornea via a narrow lamellar entrance between two corneal layers at 300 μm depth beneath the corneal surface. Since MyoRing is a complete ring it can achieve both visual rehabilitation and stop of progression. The procedure is very safe and effective and lasts only 10 to 15 minutes. It is performed under topical anesthesia and is intra- as well as postoperatively free of pain. Complications are extremely rare.
