Approaching the Spring Festival, I wish you all a happy family and all the best!
With the development of the times, ophthalmic technology has also moved to a new height, and the development of cataract surgery technology is particularly eye-catching. Since cataract surgery has entered the refractive era, patients can not only see more clearly, but also have the comfortable feeling of being off the glass. What kind of technology makes such a great result?What is the feedback from patients on this?How to ensure the quality of surgery?It is hoped that the following popular science can answer the questions in the minds of the majority of patients.
Surgical techniques have evolved in tandem with intraocular lenses.
The rapid improvement in the effectiveness of cataract surgery is due to the development of both surgical technology and intraocular lens technology. On the one hand, the improvement of phacoemulsification equipment and other technologies used to remove cataracts has promoted the upgrading of surgery from large incisions to small incisions, making the surgery more accurate, controllable and safe. On the other hand, the intraocular lens used to replace the turbid cataract lens has developed from the traditional monofocal to bifocal, trifocal and other types, breaking through the limitation that the monofocal intraocular lens can only choose one of the two to see far and near and still need glasses to assist after surgery, and can be used by patients to choose according to their own eye needs, and to solve common refractive problems such as presbyopia and myopia in cataract personally, and restore the visual effect close to that of normal people. Clinically, many patients with complex cataracts with eye diseases such as high myopia also have the opportunity to restore high-quality vision with the help of refractive intraocular lenses.
The development of intraocular lenses brings more and better choices to patients, and for doctors, the more important task is to ensure that patients meet the implantation requirements of the selected intraocular lens, for this reason, we will require patients to undergo professional ophthalmic examinations before surgery, including fundus, astigmatism, ophthalmic optical indicators, eye examinations such as kappa angle, alpha angle, and physical examinations such as blood routine, so as to strictly check the feasibility and safety of surgery.
Physics professor "rejuvenation" because of trifocal
A few years ago, a physics professor at Fudan University came to see him, and his situation was quite special. Generally speaking, cataract surgery is a "one-step operation", i.e. the implantation of an intraocular lens that best meets the patient's needs for life. However, when the old professor underwent cataract surgery a few years ago, due to technical limitations, he could only choose a monofocal intraocular lens, although the postoperative distance vision could reach 10, but reading, writing and other near-vision scenes are quite difficult, you need to wear reading glasses to see clearly, and there are many inconveniences in life. Later, during his study in Germany, he heard that the intraocular lens technology had made a qualitative leap, and the all-vision trifocal intraocular lens could achieve clear vision in the far, middle and near distances, and he did not need to wear glasses in any scene, so he came up with the idea of replacing the intraocular lens. Clinically, the full-vision trifocal intraocular lens is mainly used for integrated cataract, presbyopia, myopia and other problems to improve visual clarity and eye convenience. Intraocular lens replacement after surgery is uncommon, and the risks and prognosis of surgery are difficult to control. In particular, the old professor was old and worried that the trauma caused by the replacement surgery might be too much to bear, so we did not recommend replacement at first. However, in order to meet his needs as much as possible, we considered that the risk of trauma was within a controllable range after careful examination and evaluation, and finally performed intraocular lens replacement for him after many times of communication and confirmation. The operation went well, and the old professor took off his reading glasses as he wished, and excitedly described the postoperative effect as "rejuvenation".
Improve theoretical knowledge, fine technical operation, and promote the development of refractive cataract surgery.
The old professor's story refreshed my understanding of intraocular lens technology, and also proved to the majority of patients that a successful operation requires adequate preoperative communication, exquisite technology, and appropriate intraocular lens selection. Preoperative communication can help doctors assess the patient's eye needs and demands, so as to select the most appropriate intraocular lens; It can also help patients understand the principles and processes of surgery, weigh the pros and cons of different surgical options, and establish reasonable expectations for surgical results to improve postoperative satisfaction. The exquisite technology requires doctors to be proficient in the basic operation skills of cataract surgery, and also requires doctors to be fully involved in the field of eye diseases such as fundus disease, corneal disease, and glaucoma, so as to flexibly respond to complex situations such as joint surgery.
In order to train more qualified ophthalmologists and better carry out eye diseases such as cataracts, almost every hospital will arrange doctors to enter various academic groups to rotate to improve the knowledge system and enrich work experience. At the same time, it actively promotes ophthalmologists to participate in scientific research and innovative practices, shares advanced experience based on patient samples, and promotes the improvement of clinical excellence. In addition, the continuous improvement of ophthalmology technology and the constantly updated needs of patients have also prompted ophthalmologists to learn for life, catch up with the pace of technological development, and apply international cutting-edge diagnosis and treatment methods to clinical practice to benefit the majority of eye disease patients.
In the future, with the innovation of ophthalmic technology, ophthalmologists will face more challenges, and I hope that every ophthalmologist can have the spirit of Bethune in their hearts, take it as their responsibility to help patients restore their eye health, continue to move forward on the road of medicine, and help more patients find their own light of happiness.
