In the 2010-2017 Annual China Hospital Ranking released by the Institute of Hospital Management of Fudan University, Xiehe has ranked first for eight consecutive years. This result is not unexpected, whether it is the people's reputation or industry recognition, Xiehe is the best general hospital in China.
The Xiehe Refractive Cornea Professional Group is the first unit to carry out excimer laser surgery in China, and it is also the deputy leader unit of the Ophthalmic Corneal Disease Professional Group of the Chinese Medical Association and a member unit of the Asian Dry Eye Society and the Asian Society of Corneal Diseases, ranking eighth in the "Annual Chinese Hospital Specialty Reputation Ranking". The Department of Ophthalmology of Union Medical College has the earliest eye bank approved by the state, is a national consultation center for difficult corneal diseases, and is equipped with advanced myopia laser surgery equipment, which can carry out various refractive surgeries, including SMILE ReLEx, LASIK semi-femtosecond, LASIK, all-laser TransPRK, LASEK, SBK, PRK, PTK, etc., and patients have a wider choice of surgical types than their colleagues.
In addition to the most popular SMILE femtosecond and LASIK femtosecond, TransPRK is also a type of superficial corneal refractive correction surgery that Concord vigorously promotes. TransPRK is a huge transformation from "knife" to "knifeless", only operating on the surface layer of the cornea, with strong safety, no need to make corneal flaps, no need to enter the stroma to take lenses, no alcohol soaking, no epithelial curettage, and no complications during the operation; The operation is simple, after the laser is hit, the cutting is completed in one step from the epithelium to the stroma, the wound is small, the damage to the corneal structure is small, the wound can be completely healed, and it is not afraid of external impact; The corneal thickness is not required, and patients who are afraid that the cornea will become thinner after surgery can rest assured. The Armas 750s device used by Concord can monitor the patient's eye status at any time during the operation, and with SPT intelligent pulse technology, it can make the corneal cutting surface smoother and ensure the accuracy of the operation. However, its disadvantages are also obvious, compared with femtosecond, TransPRK has low accuracy, and there may be a risk of undercorrection or overcorrection, which requires high clinical experience from doctors. The recovery period is long, the pain may last for 2 months, and the eyes should not be exposed to ultraviolet rays for 4 months after surgery, and at the same time, it should be combined with hormones and non-steroidal drug treatment, and the number of follow-up visits is large, and the probability of corneal haze (haze) is high, and it is not suitable for people with scar constitution. Considering the excellent long-term visual quality of Trans-PRK, it is a worthy option for people with strong follow-up, low to moderate myopia (less than 600 degrees), thin corneas, special occupations (military, police, athletes), and sports lovers, and its price is also the lowest among mainstream refractive correction surgeries.
In addition, although ICL intraocular lens implantation surgery is not included in the scope of laser correction surgery, it will not be discussed in detail in this list, but because it does not require periiris resection, it reduces the damage to eye tissue caused by surgery, and can correct myopia up to 2000 degrees, 1000 degrees of hyperopia, and astigmatism of nearly 600 degrees, and will not lead to complications such as corneal ectasia and keratoconus that may be induced by corneal refractive surgery. Dr. Luo Yan of Xiehe has extensive clinical experience in this field and leads the world in the number of surgeries, which is undoubtedly an intraocular surgery worth considering for patients with moderate to high myopia and thin corneas.
There are many famous doctors in Xiehe, chief physician Li Ying is a well-known expert in corneal disease and refractive surgery in China, often active in various refractive correction science programs and forums, good at all kinds of laser myopia correction surgery, as well as the treatment of complications after laser refractive surgery, refractory corneal disease, conjunctival disease, keratoconus and other diseases, Tuesday and Friday mornings in the ophthalmology outpatient clinic, the registration fee is 100 yuan; On Wednesdays, at the special needs ophthalmology clinic, the registration fee is 300 yuan; On Fridays at International Medical Care (Ophthalmology), the registration fee is 900 RMB. At the same time, Dr. Li Ying is also a special expert in a number of private ophthalmology, if you wait too long for surgery in Xiehe, you may wish to consult the doctor which institution to practice more to speed up the progress of surgery. If it is not for a famous doctor, Xie's other refractive doctors are also excellent examples of experienced and responsible, and it is relatively convenient to register for consultation and make an appointment for surgery.
The price of femtosecond LASIK is 16,800 yuan/binocular, the price of femtosecond SMILE is 26,800/binocular, and the price of TransPRK is 15,800 yuan/binocular. The preoperative examination fee for ICL intraocular lens implantation is 700 yuan to 1000 yuan, the preoperative blood test fee and drug fee are 700 yuan, the lens without astigmatism is 12000 yuan/monocular fee, and the lens with correctable astigmatism is 15000 yuan/monocular fee. At present, Peking Union Medical College Hospital has opened five registration methods: APP appointment, telephone appointment, online appointment, bank card appointment and hall self-service machine appointment, among which APP appointment is very convenient, and a new number source is released at 16:00 pm every day, and the price of ordinary outpatient clinic to well-known expert number segment is 50 yuan-100 yuan, and the price of special outpatient clinic from deputy chief physician to chief physician is 200 yuan-300 yuan, and special registration is self-pay and does not participate in medical insurance. The app also provides services such as self-service payment (only for self-paying users), viewing doctor's visit information, obtaining report forms, and case filing.
Risk Warning:
Solve the common complications of refractive correction surgery
(1) Dry eye syndrome
Dry eye syndrome after laser surgery is the destruction of the corneal sensory nerve endings. The occurrence of dry eye syndrome is a high probability event, and almost everyone has experienced dry eye to varying degrees and at different times. In contrast, ICL surgery rarely causes dry eyes.
For patients with myopia who are dry (still within the normal range) or have poor tear film stability, it is recommended to choose a surgical method that destroys nerve endings less than ordinary LASIK, such as ReLEx has less damage to nerve endings than ordinary LASIK, while ICL has almost no damage to nerve endings. For most patients, dry eye disease improves as nerve endings recover and the nervous system compensates.
(2) Glare
The direct cause of glare is that the surgically created optical area (the size of a lens) is not large enough, and the light enters the pupil and is refracted at the edge of the light area, resulting in glare, which is usually noticeable when looking at the light source.
When wearing glasses, especially rimless glasses, light can also pass through the edges of the lenses, which should be experienced by myopia patients. The smaller the light zone and the larger the pupil, the more prone it is to glare. As a result, light sources in the field of view tend to glare when the environment is dark (a typical environment with dim and complex lighting is driving at night).
If you want to avoid glare, you must first do a good job of preoperative screening, and patients with large dark room pupils must choose a large enough light area in the design of the surgical plan. Generally speaking, the higher the degree of myopia, the smaller the light area, because the thickness of the laser surgical cut is limited; Lens surgery is similarly limited by the size of the implanted lens. Laser surgery is also limited by corneal thickness. In general, lens surgery can create a larger area of light than laser surgery.
In fact, glare will not go away, and it is recommended not to drive at night for the first three months, because patients can generally get used to the presence of glare after three months.
(3) Refractive regression
Refractive regression (rebound of vision) is a common problem with laser surgery, which means that the effect of surgical correction of the area light is reduced.
For example, a person's eye axis is elongated so that he has 600 degrees of myopia, which is corrected by laser surgery. When he recounts 100 degrees of myopia a year later, there are two possibilities, one is that he is more nearsighted (700 degrees) and the other is that the laser surgery has regressed (now only 500 degrees have been corrected). The former is called myopia deepening, and the latter is called refractive regression (rebound). Therefore, it is recommended to go for surgery when you are older and your prescription is stable.
The reason for the rebound is that after the laser surgery cuts part of the cornea, there is a hyperplasia, thickening and deformation, but when the correction is low, such as 300 degrees, the rebound may be less than 25 degrees, which is completely imperceptible to the patient, so patients with altitude should pay more attention to this situation.
(4) Keratoconus
Iatrogenic keratoconus is one of the most serious complications of laser surgery, and the main way to prevent this condition is to ensure that the postoperative corneal thickness is above the safety line. The remaining corneal stromal bed thickness can be roughly estimated using the following formula, i.e., remaining stromal bed thickness = preoperative central corneal thickness - corneal flap thickness - laser cutting depth. For example, if the thickness of the cornea center is 530 mm, the thickness of the corneal flap is 130 mm, and the laser cutting depth is 60 mm, the thickness of the remaining corneal stromal bed is 530-130-60 = 340 mm.
At present, most clinicians believe that the remaining corneal bed thickness after LASIK is at least 250 mm, or one-half of the preoperative central corneal thickness. However, this figure is based only on clinical statistics and is not based on any tangible laboratory results. Even if the stromal bed is retained at 250 mm after LASIK, there is no guarantee that corneal dilation will not occur after surgery. Therefore, the higher the degree of myopia corrected, the thicker the corneal flap, the thinner the corneal stromal bed preserved after surgery, and the greater the likelihood of secondary keratoconus. From this point of view, the superficial cutting technology, i.e., Trans-prk, still has certain advantages over LASIK, because the superficial cutting technology only makes a corneal epithelial flap with a thickness of about 50~60 microns, which is thinner than the corneal flap of ordinary LASIK, and the biomechanical structure of the cornea is more intact after surgery.
In addition, noniatrogenic keratoconus is currently of unknown etiology and cannot be cured.
