Cataracts "fog" your life? Choose the correct artificial lens to solve presbyopia and astigmatism in one go
According to data from the National Health Insurance Administration, approximately 229,000 cataract surgeries were performed in 2018, which increased to 244,000 in 2020, indicating that the number of patients in Taiwan who are in need of cataract surgeries is growing. Cataract surgery restores the patient’s vision by replacing the intraocular lens. With the advancement of medical technology, there are more and more types of intraocular lenses, and the choice of lens has become a topic that patients must consider carefully.
It is important to choose the right lens according to your personal eye needs
Lin Hongyu, deputy director of Xiu Chuan Memorial Hospital, said that clinically it is recommended that when patients choose intraocular lenses, they can consider their own eye needs based on the nature of their work and leisure activities if their financial situation can afford it. For example, although focal intraocular lenses can provide patients with clear vision at specific visual distances, as cataract patients become younger and the popularity of mobile phones increases, patients’ visual distance requirements become more and more extensive. Even if multifocal intraocular lenses provide near, intermediate, and near vision, Clear vision at long distances, but areas between focal points may be blurry. In addition, there will be glare problems in low-light environments. If you need to use your eyes at night, it is recommended to discuss other more suitable artificial lenses with your attending physician.
Full-focus artificial lens with wide visual distance range and continuous vision improves visual quality
He added that the human eye has ciliary muscles in its structure, which can adjust the lens according to different viewing distances to achieve focusing. In order to compensate for the blurred vision between different viewing distances, the full-focal intraocular lens simulates the function of the ciliary muscle, and has an extended focal length based on the multifocal intraocular lens. The closest viewing distance can reach 33~40 cm, maintaining good mid- and long-distance vision. Vision, like a zoom lens, provides clear continuous vision, allowing patients to see more clearly between focal points at different viewing distances. There will be no glare problems in low light environments, greatly improving safety, and the characteristics of the closest viewing distance are also corrected. The problem of presbyopia is eliminated, and there is no need to wear reading glasses after the operation, making life more convenient.
Doctors for cataract patients with astigmatism: lens replacement can be done in one go
Vice President Lin Xiuyu said that about half of Taiwanese people have astigmatism problems. Astigmatism will cause patients’ vision to have overlapping images and halos, affecting the quality of life and road safety. Therefore, in addition to the visual distance, when choosing an artificial lens, consider , Astigmatism correction is also very important. If a cataract patient has astigmatism of more than 75 degrees, it is generally recommended to choose an artificial lens with astigmatism correction function to solve the cataract and astigmatism problems at once, and the new generation of astigmatism correction technology allows the lens to be more stable in the capsular bag. Stable and improve postoperative stability.
Middle-aged driver who frequently uses mobile phone will develop premature cataracts
Excessive use of mobile phones may accelerate the turbidity and hardening of the lens, causing more and more people to suffer from early-onset cataracts. Vice President Lin shared that in the clinic, a 47-year-old bus driver with thousand-degree myopia and 200-degree astigmatism was diagnosed as a patient with early-onset cataracts. The cataract increased his degree to 2,000 degrees, which not only affected driving safety, but also affected the passengers. It’s not clear how much money was invested. After a detailed discussion with the doctor, it was decided to replace the new generation full-focal astigmatism-correcting intraocular lens. After the operation, the myopia degree is below 50 degrees. I no longer need to wear glasses. The astigmatism problem has also been solved. I can safely transport passengers and enjoy a beautiful and clear life.
Vice President Lin Hongyu of Xiuchuan Memorial Hospital said that when choosing an intraocular lens, you should consider your eye needs based on the financial burden, nature of work, and leisure activities. With the younger age of cataracts and the popularity of mobile phones, the visual distance requirements are becoming more and more widespread, and with low There will be glare problems in the light source environment, so it is recommended to discuss the appropriate artificial lens with the attending physician.
