Director Zhang Yang graduated from Kunming Medical College, 1998, and has been engaged in clinical ophthalmology, teaching and scientific research for a long time. He went to Chongqing Daping Hospital, Tianjin Eye Hospital and Beijing Huangsi Cosmetic Surgery Hospital, the medical beauty center of the whole army. He has rich clinical experience and high surgical level in strabismus, pediatric ophthalmology and eye plastic surgery. Up to now, strabismus surgery 10000 cases, eye plastic surgery 6000 cases, lacrimal duct diseases, eye trauma and other operations have been completed. Eye plastic surgery is good at double eyelid surgery, epicanthus correction (opening canthus), ptosis correction, ptosis correction, lacrimal groove deformity correction, eyebrow ptosis surgery, facial lifting (wrinkle removal), facial micro-plastic surgery, eyelid ectropion correction, orbital fracture reduction, enucleation+orbital implantation, conjunctival sac formation, symblepharon, eyelid and face. In 2009, combined with neurosurgery, the first reconstruction of orbital contents (orbital filling) after orbital tumor resection in our province was completed. A new operation method of eyelid insufficiency after facial paralysis was improved and created: high-density porous polyethylene lower eyelid transplantation combined with lateral eyelid batten suspension. This method can not only reconstruct the function of eyelid closure, but also solve the aesthetic problems of patients to the greatest extent. This technology is at an advanced level at home and abroad. Great achievements have been made in the diagnosis and treatment of strabismus. In addition to conventional strabismus, various complex paralytic strabismus, A-V sign, special types of strabismus (such as DVD, DHD, fixed esotropia, eyeball retraction syndrome, TAO or restrictive strabismus caused by orbital fracture, Brown syndrome, etc.) have been developed. Current new technology: 1. Modified Knapp strabismus correction; 2. Separation of anterior ciliary artery; 3. Lengthening and moving up the lower eyelid after facial paralysis; 4. Facial elevation after facial paralysis; In a leading position in the province.
