Optometric Applications for Three-dimensional Printing: A Technical Report from Low Vision Rehabilitation Practice.

SIGNIFICANCE: Delivering personalized three-dimensional (3D)-printed solutions for our patients is easier now than it has ever been. This technological revolution makes things possible that it would be extremely challenging to achieve using traditional approaches.

PURPOSE: The purpose of this study was to increase awareness among the optometric and vision science community of opportunities to apply 3D printing to enhance clinical practice and research.

METHODS: A widely available fused deposition modeling 3D printing approach was used to fabricate several plastic items for use in optometric practice and low vision rehabilitation.

RESULTS: The authors will share nine optometric extensions of 3D printing: (1) an attachment for glare-acuity testing, (2) a disposable cover paddle to limit infection spread for red-eye visits, (3) ophthalmic equipment repair/modification, (4) ophthalmic lens thickness calipers, (5) NoIR lens filter flipper, (6) Optivisor faceplate, (7) EasyPocket lanyard card holder, (8) dome magnifier handle, and (9) a phoropter near card holder.

CONCLUSIONS: Designing customized solutions and problem-solving for our patients and offices are becoming easier to do using 3D printing every year. The possible applications for this technology are constantly being expanded. This technology allows for cost-effective production of solutions, some of which would not be feasible otherwise.
