Ming Vision & Ophthalmology is a one-stop, full-procedure, precise and personalized myopia surgery platform, focusing on vision improvement surgeries that cross the two disciplines of optometry and ophthalmology, including myopia, hyperopia, astigmatism, presbyopia and cataract. With the changes and development of society, people with both myopia and presbyopia have become a key group requiring urgent attention. The Maikeshi presbyopia laser surgery fulfills the wish of people entering the presbyopia stage to regain youthful vision. Since 2015, Professor Li Ying has been performing presbyopia laser surgery to help clients aged 40 and above, and has accumulated extensive experience in clinical plan design.

Professor Li Ying shares insights and answers questions

At the conference, Professor Li Ying shared the presentation "Clinical Practice of Presbyopia Laser Correction Surgery". In her speech she deeply analyzed the difficulty of presbyopia surgery, namely the personalized design of presbyopia treatment. For patients with age-related accommodative insufficiency combined with refractive error, it is necessary to make a reasonable option and design among the bilateral myopic plan, the monovision plan and the optimized monovision plan, taking into account each person's ocular conditions and the needs for distance, intermediate and near vision. At the same time, standardized and comprehensive preoperative examinations, refraction and comfort trial wear are also the keys to achieving good results.

Tao Ye, Executive President of the Jianguomen Branch of Ming Vision & Ophthalmology, Jia Shiwei, Senior Optometry Technician of the Jianguomen Branch of Ming Vision & Ophthalmology, and Guo Yun, Director of the Reception Center of the Jianguomen Branch of Ming Vision & Ophthalmology, respectively gave excellent on-site presentations on the standardized operation of the Maikeshi presbyopia surgery equipment, preoperative refraction and trial wear for presbyopia surgery, and patient communication.

A normal cornea is an aspheric structure that is thin in the center and thick in the periphery. The average central corneal thickness in Asians is about 530 microns, and a cornea thinner than 500 microns can be considered a thin cornea. For patients with thin corneas, Ming Vision & Ophthalmology proposes that when choosing the refractive surgery method, consideration should be given to the patient's ocular conditions, personal wishes, and occupational and lifestyle needs, and that thin-flap femtosecond LASIK, implantable lens surgery, or corneal laser surgery combined with corneal cross-linking reinforcement should be appropriately adopted to help patients give up glasses.

Thin-flap femtosecond LASIK is suitable for people with high and ultra-high myopia and relatively thin corneas, and is a type of personalized femtosecond-assisted LASIK. During the surgery, Ming Vision & Ophthalmology creates a corneal flap with a thickness of 90 μm and uses the VISX S4-IR laser equipment, which consumes less corneal tissue, to maximize the saving of corneal ablation thickness, saving an average of 5 to 7 μm per 100 degrees. Meanwhile, for patients with thin corneas who do not necessarily need laser surgery, Ming Vision & Ophthalmology also fully carries out implantable lens surgery for myopia, and mainstream lenses such as Longjing and ICL-V5 are available for patients to choose.

Zhang Jing, Assistant to the Chief President of Ming Vision & Ophthalmology, shared the presentation "New Advances in the Diagnosis of Keratoconus and the Choice of Indications for Refractive Surgery Combined with Cross-Linking" on site. For keratoconus patients identified during the screening before corneal laser surgery, corneal cross-linking treatment can effectively control the condition and prevent further deterioration of the disease. For myopic patients with high myopia or relatively thin corneas, laser myopia surgery combined with corneal cross-linking reinforcement can effectively prevent corneal ectasia, and irregular astigmatism is also effectively suppressed, thereby further stabilizing long-term postoperative vision.
