Abstract

In certain embodiments, a system for performing refractive treatment of an eye comprises a laser, a printer, and a computer. The laser emits a laser beam to prepare the eye for the refractive treatment. The printer prints material onto a print area of a target. The printer comprises a printer head and a printer controller. The printer head directs the material onto the print area, and the printer controller moves the printer head to direct the material onto a specific location of the print area. The computer comprises a memory and processors. The memory stores instructions for a pattern for the target. The pattern is designed to provide the refractive treatment for the eye. The processors instruct the printer controller to move the printer head to print the material onto the print area according to the pattern.
