Described herein are delivery devices and methods of using the devices for delivering an ocular implant into a suprachoroidal space without use of a goniolens. The system may include an illumination source, a platen, a light detector, an optical train, and a computational unit. The control circuit is coupled to a processor running window environment software and having a display. The magnetic sensor is inserted into an axial gap between the pair of magnetic yokes without contacting the magnetic yokes. Said method comprising fermentation of Escherichia coli microorganisms wherein at least one of the nucleotide sequence coding for the gcvT, gcvH, and gcvP gene is overexpressed. Embodiments may also include etching the storage component material so that at least a portion of the storage component material remains on the approximately vertical walls and the bottom of the trench, wherein the trench is contacting an electrode and a selector such that storage component material on the bottom of the trench contacts the electrode.
