BACKGROUND: This study describes a novel method of customised spectacles prototyping and manufacturing using 3-D printing technology.
METHODS: The procedure for manufacturing customised spectacles using 3-D printing technology in this study involved five steps: patient selection; using surface topography; 3-D printing of the phantom model; 3-D designing of the spectacles; and 3-D printing of the spectacles.
RESULTS: The effective time required for 3-D printing of the spectacles was 14 hours. The spectacles weighed 7 g and cost AUD$160.00 to manufacture. The 3-D-printed spectacles fitted precisely onto the face and were considered to provide a superior outcome compared with conventional spectacles. Optical alignment, good comfort and acceptable cosmesis were achieved. One month after fitting, the 3-D-printed spectacles did not require further changes.
CONCLUSION: Customised 3-D-printed spectacles can be created and applied to patients with facial deformities. As a significant number of children with facial deformities require spectacle correction, it is essential to provide appropriate frames for this group of patients. The 3-D printing technique described herein may offer a novel and accurate option. It is also feasible to produce customised spectacles with this technique to maximise optical alignment and comfort in special conditions.
