Brief Summary:
Cataract is the number one cause of blindness, and the main treatment method is surgery to remove the cloudy lens and install an intraocular lens. The operation relies on ophthalmic micromanipulative instruments, but in complex cases such as abnormal lens capsule, ocular trauma, etc., the difficulty of surgery increases, so that conventional instruments are often unable to complete the operation well. In order to better cope with these complex situations, we designed and improved a new set of multi-functional cataract surgery auxiliary devices, including ophthalmic surgery auxiliary hooks, eye retractor hooks and membranous cataract scissors, which have obtained utility model patents and first-class medical device filings. Their common feature is that they have the function of 2-3 traditional surgical instruments, which can be switched intraoperatively, reduce the replacement of different surgical instruments, reduce the number of surgical instruments in and out of the incision, reduce trauma and improve surgical efficiency. The purpose of this multi-center prospective clinical study is to verify the advantages of this new group of multifunctional devices and further summarize the experience and improvement by comparing the safety and effectiveness of traditional cataract surgical instruments combined with new multifunctional cataract assisted surgical instruments and traditional cataract surgical instruments alone.
