Innovative technology! Weiren Medical Intelligent OCT guided digital laboratory configuration of corneal shaping lens

In recent years, myopia among children and adolescents in our country has shown a trend of high incidence and low aging. As a rare means to delay the development of children's myopia in clinical practice, corneal shaping glasses can effectively control the rapid growth of the ocular axis and the rapid aggravation of myopia, and are increasingly widely used. At present, the fitting of corneal shaping lenses is mainly based on the test piece method, which depends on the subjective experience of professional doctors. It is also easy to lead to problems such as inaccurate fitting of corneal shaping lenses and low success rate of fitting.

Guangdong Weiren Medical Technology Co., Ltd. (hereinafter referred to as "Weiren Medical"), relying on the characteristics of OCT high-speed, high-definition, micron level quantitative analysis, and the advantages of its own artificial intelligence team, optimized and upgraded the original scanning mode and algorithm, and innovatively launched the OCT guided corneal shaping lens digital test configuration scheme. The digital laboratory matching scheme can shorten the learning curve of doctors, reduce the requirements for doctors' experience, accurately measure the vector height, make the data more intuitive, reduce the error of data conversion, and improve the success rate of one-time matching. At the same time, digital laboratory matching can simulate fluorescein sodium staining, thus avoiding teenagers' discomfort and allergy to fluorescein sodium staining in the process of matching, and can accurately judge the positioning and wearing tightness of corneal shaping glasses, reduce the number of times of trying on glasses, and greatly improve the comfort and safety of the wearer.

"The mainstream fitting method of domestic corneal plastic lenses is still trial wear assessment, and sodium fluorescein staining is required to observe the tear thickness between the lens and the cornea. This fitting method requires high experience for doctors, different doctors will have different habits and ideas, and there is a physiological limit for naked observation of fluorescence reaction. Weiren corneal shaping lens digital test matching scheme can provide objective and accurate quantitative analysis, which opens a new idea and method for further improving the matching success rate. " Mao Xinjie, director of the Eye and Optics Hospital affiliated to Wenzhou Medical University, affirmed Weiren Medical's innovative plan.

Mei Ying, President of the Ophthalmology Center of Shanghai New Hongqiao International Medical Center Park, pointed out: "Now some corneal shaping lenses are designed based on the concept of sagittal height, so the sagittal height measurement of OCT is more intuitive, which will also help the accuracy and success rate of fitting. The OCT stain free tear film thickness analysis under the lens is a new evaluation scheme, which shows us a better possibility in the future. "

Weiren OCT guided digital test and matching scheme of corneal shaping lens can realize stain free, digital quantitative evaluation, and help precise and intelligent matching of corneal shaping lens.

Before wearing the lens, 18mm panoramic anterior segment scanning can realize free chord length and sagittal height measurement, which provides more data support for corneal shaping lens selection, especially suitable for corneal shaping lenses that have been proposed to be matched with the concept of sagittal height in recent years. After wearing the lens, the relationship between the lens and the cornea can be analyzed quantitatively based on the micron level. While eliminating sodium fluorescein staining, it breaks through the 20 micron limit of fluorescence observed by the naked eye to provide doctors with quantitative fitness assessment support.

At the same time, in the application process of corneal shaping lens, OCT can accurately locate the depth of corneal injury caused by improper wear or care, and protect doctors and patients in terms of safety.
