The general electronic ophthalmic diagnostic device developed by the Waudo District People’s Hospital in Nampho is winning popularity with experts and patients.

“The general electronic ophthalmic diagnostic device has such functions as funduscopy, sectional magnification retinography, and corneal thermography, slit lamp microscopy and ultrasonography,” said So Pyong Guk, director of the hospital, adding it is portable and can be powered by both 220V AC and 12V DC.

According to him, since existing ophthalmic diagnostic tools are suited to individual tests, they caused inconvenience and took much time and electricity. But the newly developed device overcame such shortcomings, while improving the accuracy.

Also, it can be made at a low production cost.

The developer is Ryu Chol Ryong, an ophthalmologist at the hospital.

He is said to have spent seven years building the device.

“At that time, we were having many troubles in the treatment of patients with eye diseases for the lack of diagnostic tools. Such reality pushed me into developing the new diagnostic device,” said Ryu.

Although he had little understanding and no reference information about diagnostic devices, he disassembled several devices dozens of times to learn their structures and principles and devoted all his energy to the development work in collaboration with technicians.

To develop a comprehensive ophthalmic diagnostic device of Korean style—it was his goal.

His wife Choe Un Ju used to complain to him as he treated patients in daytime and worked hard on the device at night, asking why he made his own troubles since a doctor’s duty is to do the treatment.

Then he would say that he felt a pang of conscience as a doctor whenever patients suffered due to the lack of equipment, she said.

Afterwards, she became her husband’s supporter and assistant, and finally they successfully built the diagnostic device.
