Many people say that eyes are the window to the heart, but eyes are more important than that. When we just woke up, we must open our eyes first before getting out of bed to do other activities. Eyes are, therefore, important because they make us see and perceive things that happen around us. But for those who lost their eyes, either due to congenital disability or an accident, they not only cannot see but also suffer in terms of individual image, social interaction, and other opportunities.
The ‘Prosthetic Eye Center’ of Thammasat University Hospital provides ocular prostheses to people who have lost their eyes free of charge, under the policy proposed by Assoc. Prof. Gasinee Witoonchart, the Rector of Thammasat University, while serving as the Vice Rector for Planning and Quality Development and the acting Dean of the Faculty of Dentistry, Thammasat University in 2015. The project was initially supported by Bangkok Bank with the funding of 600,000 THB together with extra supports from Prof. Dr. Sittichai Koontongkaew, D.D.S. And Assoc. Prof. LadyAmpornSukhonthamarn, M.D..
The Prosthetic Eye Center has adopted a multidisciplinary approach, with the joint effort from ophthalmologists, dentists, and engineers, to create 3D-printed ocular prosthesis that matches the real eye and requires less time to produce. “In creating permanent ocular prosthesis, a lot of time is required to draw the sclera and the pupil that perfectly match the other eye”, Adj. Prof. Dr. Sakchai Wongkittirak, M.D., the Director of Thammasat Eye Center said.
In the multidisciplinary development process, the ophthalmologists will assess the type of prosthetic eye that is suitable for each case. Then the engineers implement 3D printing technology, starting by scanning the patient’s eye to capture the color of the pupil and the blood vessels in the sclera which are unique. The 3D printer will adjust the color of the prosthetic eye to match the real eye. The 3D-printed ocular prostheses are produced using the material used in dentures, which thus requires the supervision by dentists.
The 3D-printed prosthetic eyes can be completed in a matter of hours, allowing them to be used while the patients are waiting for their permanent ocular prosthesis. The 3D-printed temporary prosthetic eyes do not have any negative effect, can be worn for a long period of time, and can be taken out to clean in the same way as contact lenses. If these 3D-printed prosthetic eyes are developed to be more durable, there are chances that they can be used as permanent ocular prostheses.
The 3D-printed prosthetic eyes innovation has won a national-level excellence award in service innovation from the Office of the Public Sector Development Commission On 16 September 2020. Thammasat Eye Center received this award for the second consecutive year. In 2019, the Center won an award from ‘music therapy during phacoemulsification surgery’ from the Thammasat Cataract Center.
