cataract<\/span>is the leading cause of blindness worldwide. The World Health Organization (WHO) reports that an estimated 19.34 million people globally are blind due to age-related cataracts, accounting for 43% of all cases of blindness.1<\/sup>\u00a0As the population grows and lives longer, the number of blind people and the rate of cataract blindness in the world will continue to rise. Common cataract symptoms include blurred vision, glare, landscape colours becoming dull, etc. Minimally invasive phacoemulsification is the most common type of cataract treatment. It requires the implantation of IOL (monofocal lens or multifocal lens) without hospitalisation and replacement after the treatment.<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

What is Cataract?<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

A cataract is a change in the protein of the lens in the eye that gradually degrades, hardens, and becomes opaque, so that vision is blurred as if covered by a foggy lens. The disease is likely to occur in one or both eyes, which, however, do not spread or infect each other. The condition varies depending on the location and degree of clouding of the lens. Vision loss also varies from person to person and can be severe enough to cause blindness.<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Currently, there is no medication that can effectively prevent or treat cataracts. Cataract treatment is the only recognized effective method of management.\n

\nPhacoemulsification, or phaco, is the most common type of cataract treatment. It requires only local anaesthesia. The main treatmentprocedure is the use of ultrasound to emulsify the cloudy lens into fragments which will be aspirated from the eye. Finally, an intraocular lens will be implanted. After the treatment, when all opacified materials have been removed, light can be refocused on the retina. Vision can be restored and refractive errors corrected at the same time. The treatment is not long and can be done in a day treatment centre so patient can go home directly afterwards.<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
