Tissues are more valuable than the acrylic prosthetic eye or acrylic scleral shell eye. We highly recommend proper maintenance for prosthetic eyes to prevent contamination, irritation, and possible infection. Polishing and adding the anterior clear coat of the prosthesis or scleral shell will remove protein deposits helping reduce giant papillary conjunctivitis. If this conjunctival tissue lining is damaged, it will require tissue replacement and cause bleeding. Hence, we have built a maintenance service page on our website so prosthesis eye care is achieved and prosthesis eyes are shipped back within a 24-48 hour period.
