Mechanical dissection using PocketMaker microkeratome

Mechanical dissection using PocketMaker microkeratome procedure for MyoRing implantation included the creation of pocket within corneal stroma at 8 or 9 mm diameter (based on MyoRing diameter) and 300 μm in depth using a PocketMaker microkeratome (Dioptex GmbH). After determining the correct position of the blade, the micro-vibrating diamond blade was set at 300 μm of the measured corneal thickness and a single 0.5 mm radial incision was made at the steepest meridian. Thereafter, the ring was inserted into the created pocket and its position was adjusted intraoperatively using a keratoscope.
