A system for making an implant for an eye, comprising: a printer configured to print material onto a target, the printer comprising: a printer head configured to deposit the material onto the target; and a printer controller configured to move the printer head to deposit the material onto a specific location of the target; a camera configured to generate an image to monitor the printing of the material; an ablation laser configured to shape the printed material; a computer configured to: store a pattern for the implant, the implant designed to provide refractive treatment for the eye and the pattern defining an external size and shape of the implant; send instructions to the printer controller to move the printer head to print the material onto the target according to the pattern; send instructions to the ablation laser to ablate the printed material according to the pattern; assess the image from the camera according to the pattern by: identifying an external size and shape of the printed material in the image; and comparing the identified external shape and size with the external shape and size of the implant defined by the pattern to determine a difference between the identified external shape and size of the image and the external shape and size of the implant defined by the pattern; and adjust the instructions in response to the image to reduce a determined difference by instructing the printer to print needed material or instructing the ablation laser to ablate unwanted material. a printer configured to print material onto a target, the printer comprising: a printer head configured to deposit the material onto the target; and a printer controller configured to move the printer head to deposit the material onto a specific location of the target; a printer head configured to deposit the material onto the target; and a printer controller configured to move the printer head to deposit the material onto a specific location of the target; a camera configured to generate an image to monitor the printing of the material; an ablation laser configured to shape the printed material; a computer configured to: store a pattern for the implant, the implant designed to provide refractive treatment for the eye and the pattern defining an external size and shape of the implant; send instructions to the printer controller to move the printer head to print the material onto the target according to the pattern; send instructions to the ablation laser to ablate the printed material according to the pattern; assess the image from the camera according to the pattern by: identifying an external size and shape of the printed material in the image; and comparing the identified external shape and size with the external shape and size of the implant defined by the pattern to determine a difference between the identified external shape and size of the image and the external shape and size of the implant defined by the pattern; and adjust the instructions in response to the image to reduce a determined difference by instructing the printer to print needed material or instructing the ablation laser to ablate unwanted material. store a pattern for the implant, the implant designed to provide refractive treatment for the eye and the pattern defining an external size and shape of the implant; send instructions to the printer controller to move the printer head to print the material onto the target according to the pattern; send instructions to the ablation laser to ablate the printed material according to the pattern; assess the image from the camera according to the pattern by: identifying an external size and shape of the printed material in the image; and comparing the identified external shape and size with the external shape and size of the implant defined by the pattern to determine a difference between the identified external shape and size of the image and the external shape and size of the implant defined by the pattern; and identifying an external size and shape of the printed material in the image; and comparing the identified external shape and size with the external shape and size of the implant defined by the pattern to determine a difference between the identified external shape and size of the image and the external shape and size of the implant defined by the pattern; and adjust the instructions in response to the image to reduce a determined difference by instructing the printer to print needed material or instructing the ablation laser to ablate unwanted material.
