The eye is the window of the heart, while the cataract may blur the window. cataracts are more common in many eye diseases, especially among older persons. But how did it come about? What are the treatments? Let’s find out.
The formation of cataracts is mainly related to changes in the crystals within the eyes. It is like a transparent lens between the iris and the glass, and its main function is to focus on the light that allows us to see objects clearly. Under normal circumstances, crystals are transparent, but as age increases, the proteins of the crystals change over time, just as the egg’s egg is clouded by transparency, and the crystals slowly become confused, thus affecting the passage of light, leading to a loss of vision, the most common age-related cataract.
In addition to age factors, there are a number of other reasons that can cause cataracts. Long-term exposure to UV exposure, such as for people who often work outdoors and do not have adequate eye protection, can damage the protein structure of crystals and accelerate the formation of cataracts. A number of systemic diseases, such as diabetes, cause glucose levels in crystals to increase in patients over a long period of high blood sugar, resulting in a series of chemical reactions leading to changes in crystal inoculation pressure, fibre swelling, fractures and, consequently, cataracts. Nor should the trauma to the eye be overlooked, since if the crystal was hit by external force, its structure could be damaged, perturbed, causing a traumatic cataract. In addition, the persistent use of certain drugs, such as sugar-coated hormones, may increase the risk of cataract morbidity.
Treatment needs to be considered when cataracts develop to a certain extent, affecting daily life and work. At present, surgical treatment is the main treatment for cataracts. The most common method of surgery is the combination of ultrasonic emulsion of cataracts with artificial crystal implantation. During the operation, the doctor produces a small cut on the edge of the corneal, then stretches the ultrasound probe into the eye, using ultrasound energy to emulse and siphon out the mutilated crystalline, and then implants it into an artificial crystal. This artificial crystalline is like a new, transparent “synthesis” that replaces the previously convoluted crystalline, allowing the light to re-focus on the retina, thus restoring sight. The procedure is small, quick to recover, and there is a marked improvement in post-operative vision.
Another method of surgery is flight-second laser-assisted cataract surgery. Flight-second lasers can more accurately complete some of the key steps in the operation, such as the production of corneal cut-off, tore-up, etc., which further enhances the safety and accuracy of the operation, particularly in some complex cases of cataracts, although at relatively high cost.
For some early cataracts, where the symptoms are light and have little visual impact, a strategy of observation and waiting can be adopted, together with some medication. Although drugs cannot be treated as cataracts, they can slow their progress to some extent. For example, some eye drops can be resistant to oxidation, nutrient crystals, etc. It should be noted, however, that the effects of drug treatment are limited and do not replace surgical treatment.
In daily life, we can also take measures to prevent cataracts. Whenever possible, he wears sunglasses when going out to reduce UV damage to the eye; actively controls all-body diseases such as blood sugar and blood pressure; avoids eye trauma; rational use of drugs, etc.
Although cataracts can be a problem for our eyesight, their treatment has been very significant as medical technology continues to develop. If symptoms such as loss of vision and blurry of vision are found in one ‘ s own or family, medical examinations should be made in time for early diagnosis and treatment, so that our eyes continue to be bright and clear.
