The main newer cataract treatments are ultrasonic emulsification lens extraction surgery and femtosecond laser-assisted ultrasonic emulsification lens extraction surgery, and there are more options for IOL implantation. 1. Ultrasound Emulsification Lens Removal: Using Ultrasound Emulsification Cataract Aspiration, ultrasound energy is used to emulsify the cloudy lens nucleus and cortex and then aspirate and preserve the posterior lens capsule. 2. Femtosecond laser-assisted phacoemulsification for lens extraction: The incision, capsule tearing and nuclear fragmentation are performed with the assistance of a femtosecond laser. The other steps are largely the same as those of phacoemulsification, but the operation will be more precise, and the impact of ultrasound energy on the intraocular tissues will be reduced. 3. Lens implantation: In this aspect, monofocal IOL implantation was mostly chosen in the past, but now there are more choices such as multifocal lens implantation, which can satisfy more visual needs of patients. It is recommended that cataract patients go to regular hospitals for specific examinations under the guidance of doctors and take targeted treatment according to the examination results.
