In the field of ophthalmology, the Second Hospital of Zhejiang Medical College is well-known in Hangzhou and even the whole country, and is one of the few ophthalmology hospitals in the country. In the "2016 China Hospital Specialty Reputation Ranking" released by Fudan University (the selection of the list was jointly participated by 1,579 famous experts and scholars from 30 clinical specialties across the country, and the score was formed after comprehensively examining the key factors such as discipline construction, clinical technology and medical quality, and scientific research level of each hospital), Zhejiang Second Ophthalmology ranked sixth with a score of 5.17, and the first and second ranked were Zhongshan Eye Center of Sun Yat-sen University and Beijing Tongren Hospital, respectively.
Whether it is in terms of hospital reputation, equipment or expert level, the performance of the Second Hospital of Zhejiang Medical College is impeccable. The hospital began to carry out excimer laser myopia surgery in 1996, which is one of the earliest medical units engaged in the project in China, and is also the refractive specialty with the largest number of laser myopia surgeries completed in Hangzhou every year, accounting for more than 70% of the total number of laser myopia surgeries in Hangzhou, with a success rate of up to 100%. The huge total number of surgeries not only improves the surgical proficiency of doctors, but also creates good revenue for the hospital, coupled with the strong financial support of the state, the Second Hospital of Zhejiang Medical College can afford a number of international advanced medical equipment, including German Zeiss equipment. The VisuMax laser refractive surgery system developed by ZEISS is the only system in the world that can be applied to femtosecond laser surgery. In 2016, the Second Hospital of Zhejiang Medical College comprehensively upgraded the Visumax system in the hospital, becoming the first batch of institutions in the country to unlock the VisuMax version 3.0, which expanded the indications for ReLEx surgery to 1250 degrees, far ahead of the ordinary hospitals that are still using version 2.0, and has an incomparable advantage over ordinary public hospitals.
Refractive correction surgery is not complicated, but the safety and reliability of the surgery must be based on medical equipment, expert level and preoperative safety examination, all three of which are indispensable. The Second Hospital of Zhejiang Medical College has a first-class refractive team headed by Yang Yabo, Du Xinhua and Qiu Peijin, among which Professor Yang Yabo is the most famous. Professor Yang Yabo is one of the first doctors in China to obtain a certificate for laser treatment of myopia, and he cooperated with his supervisor to develop a wavefront aberration meter and a wavefront aberration detection method during his study at Harvard. This invention allows laser surgery to be performed under wavefront aberrometer-guided conditions, making the procedure safer and more reliable. Many smaller ophthalmology institutions invite famous doctors to practice in their hospitals, and Professor Yang Yabo is the golden sign of major ophthalmology clinics and hospitals, and his professional level is beyond doubt. At present, Professor Yang Yabo's schedule at the hospital is Wednesday afternoon and Friday morning, but the number of patients who come to see him every week is huge, and the hospital usually releases numbers a week in advance, and Professor Yang's ticket numbers are often sold out within a few hours. If patients can't make an appointment with Professor Yang Yabo, they can also make an appointment with doctors such as Qiu Peijin and Wu Fang, who have easier registration consultation and scheduling than Professor Yang.
It is important to note that not everyone can undergo laser surgery, and patients must undergo a detailed preoperative examination before undergoing laser surgery. The purpose of the examination is threefold: 1. to determine whether the myopia patient is suitable for surgical treatment, 2) if the patient undergoes surgery, what kind of visual effect will be achieved after surgery, and 3. the doctor can design a personalized surgical plan suitable for the myopia patient according to the patient's preoperative examination data. The famous doctors of Zhejiang Second Ophthalmology Department are conscientious and responsible, and usually give suggestions and formulate the most suitable surgical plan from a rigorous and professional perspective according to the results of preliminary examinations and the surgical needs of myopia patients. Rather than advocating the high price of femtosecond surgery like private eye clinics.
If you decide to have laser myopia surgery, you can make an appointment through the WeChat public account "Zhejiang Medical Second Hospital", and the registration fee of the eye center is generally between 10 yuan and 150 yuan. It is of little significance to have a medical number in the early examination, because the examination is standardized by the physician's assistant, and the doctor who does the operation can choose later. At present, the cost of pre-examination and eye drops in the Second Hospital of Zhejiang Medical College is about 600 yuan, the price of full femtosecond surgery is 25,000 yuan/eye, and the price of half femtosecond surgery is 16,000 yuan/eye, and it takes about one month for patients to complete the operation from appointment to operation. Although the Second Hospital of Zhejiang Medical College is the top tertiary hospital in China, there are still common problems such as a large number of patients, noisy and crowded medical environment, and long waiting time in large hospitals.
Science:
1. Can laser myopia surgery be done? Will it be blinding?
Answer: Laser myopia surgery is not suitable for everyone, before the operation, it is necessary to use professional instruments to conduct a detailed preoperative examination of the patient to obtain the patient's naked eye visual acuity, intraocular pressure, corneal morphology, corneal endothelial cell density, preoperative total high-order aberrations and all order aberrations, ocular lens, vitreous and fundus, dry eye, corneal thickness and other detailed data, only through a comprehensive and systematic examination can determine whether it is suitable for surgery. For myopia patients who are suitable for surgery, laser surgery is to change the corneal curvature by cutting the cornea, thereby changing the refractive angle of light, so that the image is clearly imaged on the retina, so as to achieve the purpose of correcting vision. Figuratively speaking, laser surgery is equivalent to carving a pair of glasses on the cornea that never needs to be taken off, and since the surgical laser does not involve the inside of the eyeball, there is no possibility of blindness caused by surgery.
2. Is laser surgery safe? Will there be any sequelae?
A: Laser surgery has gone through more than 20 years since its inception, and its safety and effectiveness have been widely recognized by the scientific community. The operation time can be as short as tens of seconds and as long as about 20 minutes, and it has restored good vision for tens of millions of patients around the world. For myopia patients who have passed the preoperative examination, the occurrence of serious complications such as corneal ectasia and corneal infection that affect vision after surgery is very low, and the occurrence of such complications can be avoided by choosing the appropriate surgical plan, the doctor's standardized operation and the patient's postoperative care. Therefore, it is particularly important for patients to choose a formal and professional medical institution when undergoing laser surgery.
3. Will I still be myopic after surgery?
A: Many myopic people may worry about myopia after surgery, but in fact, this phenomenon may exist. It can occur for one of two reasons:
(1) Myopia caused by poor eye use. I don't know if you have found it in your life: some people have not been myopic before, and suddenly become myopic at the age of thirty or forty, or the degree of myopia has stabilized, and the number has increased in recent years. In fact, this is related to our lifestyle, living environment, excessive use of eyes and not paying attention to eye rest, and has nothing to do with whether or not laser surgery has been performed, which is also the vast majority of the reasons for the emergence of new prescriptions after laser surgery.
(2) Refractive retraction (rebound). Refractive regression refers to the proliferation of the cornea cut by the laser, if the cutting surface proliferates uniformly, it will not cause a change in degree, but when the central proliferation of the cutting surface is more than four weeks, there will be a slight regression, the possibility of regression is related to the degree of myopia, generally speaking, the possibility of refractive regression in patients with low and medium myopia is very small, and the possibility of regression in patients with high myopia is greater, however, due to the development of surgical technology, refractive regression is predictable and controllable, The regression of patients with high myopia can generally be controlled at about 5% of the original degree, which is low-grade myopia. In the unlikely event that refractive regression does occur, a second make-up surgery can be performed if the patient meets the requirements for laser surgery after the examination.
4. What are the current types of laser surgery?
PTK, also known as epidermal surgery, directly uses an excimer laser to ablate the epithelial cell layer, Descemet's layer and part of the stromal layer of the cornea. After the surgery, the corneal epithelial layer is regenerated, the Descemet's layer "disappears", and the stromal layer is partially cut according to the individual's degree. This procedure is more painful and has a long recovery time. Lasik first uses a lamellar knife or laser to make a flap, which is called semi-femtosecond, and forms a reversible "manhole cover" on the surface of the cornea, and then uses an excimer laser to cut the stromal layer to complete the correction of the corresponding degree, and then resets the "manhole cover" to complete the operation. After the operation, the epithelial cell layer was regenerated, and the incision was made in the Descemet's layer, which was about 20 mm, and the stromal layer was partially removed. At the beginning of the operation, a laser is used to make a convex lens in the corneal stromal layer, and then a micro-incision of about 2-4mm is made on the surface of the cornea to remove the lens, and the purpose of correcting vision is achieved by changing the thickness of the cornea. Compared to Lasik, the incision is smaller and the postoperative impact resistance is stronger. However, the specific type of surgery that is suitable for it depends on the results of the preoperative examination, and it cannot be simply assumed that full femtosecond is necessarily superior to half femtosecond.
