1、 "Corneal stromal lens implantation for correction of hyperopia" is the opposite

As early as 2012, Professor zhouyuehua pioneered the technology of "corneal stromal lens implantation for correction of hyperopia" on the basis of all femtosecond laser surgery, which attracted high attention from the industry at home and abroad. This achievement caused a sensation at the annual meeting of the European cataract refractive surgery Ophthalmology Association (ESCRS), and Professor zhouyuehua also won the global smile surgical quality management contribution award and surgical Excellence Achievement Award.

In all femtosecond laser correction surgery, femtosecond laser cuts a convex lens in the corneal stromal layer and takes it out through a small incision of 2mm to achieve the purpose of correcting myopia. Professor zhouyuehua envisions whether the convex lens taken out in the full femtosecond operation can be implanted into the eyes of hyperopia patients to correct hyperopia. After repeated argumentation and experiments, this technology has finally been introduced, making the correction of hyperopia change from the original subtraction mode to the addition mode.

2、 "Corneal stromal lens implantation for correction of hyperopia" tests doctors' Technology

In the past, the international conventional correction of hyperopia was to use excimer laser subtraction to correct hyperopia by ablating the central and peripheral corneal tissue with excimer laser, but for patients with high curvature and hyperopia, after surgery, the central vision was acceptable, the peripheral vision was poor, the overall visual quality was poor, and it was easy to fall back; Lens implantation surgery can solve the problem of high hyperopia, which has relatively little impact on corneal biomechanics and higher safety.

In general, the lens implantation surgery for correction of hyperopia is very fine, the operation is difficult, and the requirements for doctors are higher. Doctors need to complete lens coating, interlayer treatment and lens peripheral treatment in a short time, which requires rich experience to ensure the safety of surgery.

Back To List
Diagnosis and treatment of keratoconus
Keratoconus is an absolute contraindication to corneal laser. Beijing mingshiguang Ophthalmology, as a specialized medical institution for myopia surgery, has been studying the screening, timely diagnosis, treatment and control of keratoconus, and has made innovative progress in the early diagnosis and treatment of keratoconus. In particular, it has developed the technology of corneal stromal lens implantation combined with corneal cross-linking in the treatment of keratoconus. The corneal stromal lens removed in full femtosecond surgery is implanted into the corneal stromal pocket of keratoconus patients, and the cornea is padded thick for cross-linking, so that more patients can control the development of the disease in time.
Conjunctival pigmented nevus
There are spots on the white eye kernel, which affect the appearance. Traditional scalpel resection is easy to leave scars on the surface of the eye, which affects the vision and beauty. The PTK surgery for conjunctival pigmented nevus adopted by Professor Li Ying can accurately remove conjunctival pigment using laser, without sutures, leaving no scars, without changing the ocular surface structure and involving the corneal area, which has little impact on vision. This technology provides a precise and safe solution for those patients who are anxious about the "nevus" of the eye or seek improvement due to appearance problems.
Surgical correction of refractory ametropic amblyopia in children
If children's amblyopia caused by refractive error cannot be effectively corrected and improved with glasses, adults will face the reality of amblyopia all the time without other effective measures. Professor zhouyuehua pioneered the "laser correction of children's refractory ametropic amblyopia" in China, and successfully helped many desperate families bring hope. It not only gave these children a clear vision when they grew up, but also opened up a new research direction for the academic circle of Ophthalmology.
Medical optometry glasses
A beautiful spectacle frame can add people's temperament, but the quality of the lens determines the clarity of vision. The accuracy of optometry data not only determines the clarity of vision, but also affects the long-term comfort of wearing glasses. Ming Optometry Ophthalmology medical optometry: nearly 100 professional teams, with more than 10 years of myopia medical experience; Dozens of imported ophthalmic examination equipment to accurately collect eye data; Formulated by the optometry expert team, the glasses are personalized and accurately matched.
