Versatile low-cost ophthalmic wet lab device to improve diagnostic and surgical eye training

Introduction: Cataracts and glaucoma are the leading causes of worldwide blindness, accounting for more than 50% of blindness cases. Blindness from this condition could be treated before severe vision loss occurs. Cataract and glaucoma surgery can be performed to achieve better conditions. Training conducted by ophthalmologists for eye examinations and surgeries is carried out in wet laboratories. So, tools are needed to help facilitate training for eye examinations and surgeries, one of which is an eye holder made of affordable materials with an easy manufacturing method. Methods: The eye holder of experimental animals is designed in 3D with a funnel shape that resembles an orbital eye socket. The author made a 3D printing design to optimize the use of this device in wet lab activities. Results: Experimental animal eye holders could potentially be used for 1.) Ultrasound Biometry, 2.) Handheld Keratometry, 3.) Tonometry, and 4.) Training in ophthalmological surgical techniques. These activities can be performed stable on the animal’s eyes inside the holder in flat and inclined positions. Conclusion: This versatile experimental animal eye holder has great potential for use in wet lab activities in conducting diagnostic and surgical training by veterinary students specializing in ophthalmology, general practitioners training to become ophthalmology specialists, and optometry students.
