An ophthalmic laser system includes a laser beam delivery system and an eye tracker responsive to movement of the eye operable with a laser beam delivery system for ablating corneal material of the eye through placement of laser beam shot on a selected area of the cornea of the eye. The shots are fired in a sequence and pattern such that no laser shots are fired at consecutive locations and no consecutive shots overlap. The pattern is moved in response to the movement of the eye.

The jet injection device of claim 2 wherein said device defines a recess extending axially and including a pair of lateral extensions for receiving latching lugs carried on said injection cartridge, said safety ring including a plate-like portion partially closing a forward side of said safety ring, and defining an aperture matching said recess in shape to receive said injection cartridge including said latching lugs, in said first position of said safety ring, said aperture of said safety ring being congruent with said recess to allow said injection cartridge to move axially in and out of said recess; and in said second position of said safety ring, said aperture being rotationally disposed relative to and non-congruent with said recess so that said injection cartridge is either trapped in said recess or prevented from entering said recess by confrontation of said latching lugs with respective portions of said plate-like portion of said safety ring. 5. The jet injection device of claim 2 wherein said latching member includes a latch plate slidably movable laterally of said device body, and said latch plate defining an aperture through which a portion of said injection cartridge is received, said device including a plate-like spring member including an axially and radially extending spring arm portion, and said spring arm portion yieldably engaging said latch plate to yieldably bias said latch plate to a first position in which it latchingly engages said injection cartridge, said latch plate including an outwardly disposed finger pad by which said latch plate may be moved to a second position unlatching from said injection cartridge, and said axially and radially extending spring arm of said plate-like spring member elastically yielding to allow movement of said latch plate member to said second position. 6. The jet injection device of claim 2 wherein said latching member includes a latch plate slidably movable laterally of said device body, and said latch plate defining an aperture through which a portion of said injection cartridge is received, said device including a plate-like spring member including an axially and radially extending spring arm portion, and said spring arm portion yieldably engaging said latch plate to yieldably bias said latch plate to a first position in which it latchingly engages said injection cartridge, said latch plate including an outwardly disposed finger pad by which said latch plate may be moved to a second position unlatching from said injection cartridge, and said axially and radially extending spring arm of said plate-like spring member elastically yielding to allow movement of said latch plate member to said second position. 7. The jet injection device of claim 6 wherein said plate-like spring member further includes an axially and circumferentially extending spring finger confronting a portion of said injection cartridge, said device body including a recess into which said injection cartridge is receivable to be engaged by and carried by said device body, said recess leading to said plate-like spring member, so that said spring finger is engaged by said injection cartridge and urges said injection cartridge out of said recess. 8. The jet injection device of claim 6 wherein said gas piston further includes an axially extending stem, said plate-like spring member defining a centrally disposed guide hole, an a forward portion of said gas piston stem extending through and being guided in reciprocation by said guide hole in alignment with said injection cartridge. 9. The jet injection device of claim 6 wherein said device further includes a return spring at one end bearing upon said gas piston and urging said gas piston to a first position in preparation for receiving pressurized gas communicated thereto, said plate-like spring member opposing said return spring at an opposite end so that opposite end of said return spring seats upon said plate-like spring member. 10. A gas powered hypodermic jet injection device, said device comprising: a device body having provision for engaging with and carrying a jet injection cartridge; a gas piston reciprocable in said device body and cooperable with the jet injection cartridge to effect a jet injection in response to communication of pressurized gas to said gas piston; a valve device for effecting communication of pressurized gas to said gas piston in response to movement of said valve device from a first to a second position; a safety ring rotationally carried on said device body and in a respective first position preventing movement of said valve device from said first to said second position, said safety ring being rotationally movable to a respective second position in which said valve device is movable from said first to said second position; said valve device including a projection extending toward said safety ring, and said projection moving between a respective first disposition and a second disposition in response to movement of said valve device between said first position of said valve device and said second position of said valve device; said safety ring including a cam surface which in said first position of said safety ring confronts and is engageable by said projection, thus to prevent said valve device from moving from said first position of said valve device to said second position of said valve device. 11. The jet injection device of claim 10 wherein said safety ring further includes an axial and radially extending recess which in said second position of said safety ring aligns with and into which said projection of said valve device is receivable upon movement of said valve device from said first position of said valve device to said second position of said valve device. 12. The jet injection device of claim 11 wherein said projection of said valve device when received into said axially and radially extending recess of said safety ring in said second position of said valve device prevents rotational movement of said safety ring from said second position of said safety ring to said first position of said safety ring. 13. A gas powered hypodermic jet injection device, said device comprising: a device body having provision for engaging with and carrying a jet injection cartridge; a gas piston reciprocable in said device body and cooperable with the jet injection cartridge to effect a jet injection in response to communication of pressurized gas to said gas piston; a valve device for effecting communication of pressurized gas to said gas piston in response to movement of said valve device from a first to a second position; a safety ring rotationally carried on said device body and in a respective first position preventing movement of said valve device from said first to said second position, said safety ring being rotationally movable to a respective second position in which said valve device is movable from said first to said second position; and wherein said device body defines a cavity for receiving a gas pressure cartridge, said device body further including a door hingably attaching to said device body by means of a hinge pin, and said gas pressure cartridge being impaled at a penetrable, diaphragm portion thereof upon a penetrator member of said injection device in response to closing of said door so that gas pressure within said gas pressure cartridge acting on said penetrator member causes a recoil force directed axially of said device; said hinge pin being disposed off axis of said device body so that said recoil force passes off center of said hinge pin in a direction relative to said hinge pin causing a closing torque to be effected on said door. 14. A gas powered hypodermic jet injection device, said device comprising: a device body having a forward end; an axially extending recess at said forward end for receiving and retaining an injection cylinder which includes cy
