The higher the degree of myopia, the more powerful the fundus lesions. It is recommended that highly myopic patients with cataracts should have early surgery Xiamen Eye Center of Xiamen University Cataract Ye to 78-year-old Liu Yim had 1200 degrees of myopia when she was young and developed cataracts more than 30 years ago. Due to the lack of timely and effective treatment, coupled with the high degree of myopia with more fundus problems, the elderly almost went blind. A few days ago, she was able to regain her sight by using the smallest coaxial ultrasound emulsification device at Fuzhou Eye Hospital. According to the introduction, due to abnormalities in the structure and nutrient metabolism of highly myopic eyes, cataracts tend to appear earlier. Moreover, the higher the degree of myopia, the more powerful the fundus lesions are, and the difficulty of cataract surgery increases. Therefore, ophthalmologists remind that, in principle, highly myopic patients with cataracts should have surgery as early as possible and pay attention to preoperative evaluation and good surgical skills so that they can have good postoperative vision. In the recent past, there were two special highly myopic patients in the cataract department of Fuzhou Eye Hospital. 78-year-old Yim Liu had high myopia when she was young, and her vision was blurred even when she wore 1,200-degree glasses. As early as 30 years ago, Liu began to develop cataracts, and due to the fear of surgery, she has been seeing Chinese medicine practitioners and taking health care drugs for a long time, but her vision has been declining. Six months ago, Liu Yiem’s eyes could only see her hands moving in front of her eyes, and she needed to be accompanied by someone in her daily life, which brought great inconvenience to her life. The examination found that due to high myopia, the diameter of her eyes was severely stretched (up to 32.43mm, compared to about 23mm for normal people), the retina became very thin and the eyeball became soft, while the cataract nucleus was very hard. He had undergone laser excimer cutting of the cornea (LSAIK) surgery 5 years ago because his vision had receded, and his vision had dropped significantly in the past 2 years. Since both eyes had already undergone 2 surgeries, and there were greater risks and uncertainties in high myopic cataract surgery, Mr. Lin was always confused. High myopia cataract surgery, there are three difficulties Dr. Ye Xiang, vice president of Fuzhou Eye Hospital, said that high myopia is very easy to complicate cataract, and it happens earlier than normal people, many people only know they have cataract when they go to the hospital for examination because they feel their myopia deepens. There are three main difficulties in the treatment of high myopia cataracts: First, patients with high myopia have long eye axes and thin eye walls, and the pressure in the eye is less stable during surgery, which will make the surgery more difficult and the chance of complications is higher. Second, patients with high myopia often have combined fundus pathologies, such as retinal atrophy, macular degeneration and hemorrhage, and retinal detachment, which can affect postoperative results. Third, due to the growth of the eye axis in high myopia, the corneal and retinal morphology may become irregular, causing errors in the IOL measurement, resulting in an insignificant improvement in post-operative visual acuity. Especially for patients who had myopia surgery when they were young, IOL prescription measurement is a difficult problem, and they need to find a surgeon with extensive experience to perform the surgery. Micro-incision ultrasound emulsification can reduce post-operative astigmatism Dr. Ye Xiang introduces that surgery is not contraindicated for highly myopic cataract patients, although the surgery is difficult and the post-operative results are uncertain, the vast majority will obtain satisfactory results through detailed evaluation of the retina and accurate measurement of the IOL before surgery. For the safety of the surgery, Dr. Ye Xiang chose the micro-incision ultrasound emulsification technique with an incision of only 1.8mm for Yim Liu and Mr. Lin, which not only ensures the confinement and stability of the eye during the surgery, but also reduces post-operative astigmatism, and both of them obtained satisfactory vision on the first day after the surgery. Dr. Ye introduced that the old method of cataract surgery with an incision of about 6 to 8 mm, in which the entire cataract is removed through a large incision, is highly traumatic, slow to recover and has unsatisfactory post-operative results, and has basically been eliminated. Since the old method required taking out the whole cataract, this is the reason why it used to require the cataract to be mature before it could be done. Nowadays, we use ultrasonic emulsification technology, which uses ultrasonic waves to break up the cataract and then suck out the debris through a very thin tube, so the surgical incision is small, no sutures are needed, and complications are minimal. The Stellaris ultrasound machine with 1.8mm micro-incision adopted by Fuzhou Eye Hospital is the smallest coaxial ultrasound emulsification device in the world, and the tiny incision can make the surgery safer and more delicate with faster recovery.
