Summary

In order to better cope with complex situations of cataract surgery, 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. Their common feature is that they have the function of 2-3 traditional surgical instruments, which can be switched in operations, reducing the replacement of different surgical instruments, lowing the number of surgical instruments in and out of the incision, reducing trauma and improving 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.

Conditions

  • Cataract

Interventions

DEVICE

multifunctional instruments

Ophthalmic retractors can be used to lift the lens during surgery to assist in lens sucking or resection; Intraoperative injection of reagent, which has the advantage of retractable, micro-incision. Ophthalmic hooks can be used to secure support capsular bags; auxiliary cleavage; polishing capsule; Viscoelastic agent is injected as needed. The front end of the membranous cataract scissor is a capsular tearing forceps, and the capsule tearing and capsule scissors can be flexibly switched. All three instruments have the functions of two or three traditional instruments, which can be designed to reduce the number of times the instruments enter and exit the incision during surgery, improve surgical efficiency,

DEVICE

traditional instruments

traditional Cataract-assisted instruments for cataract operation.Puncture knives, microscissors, microscopic forceps, nucleus hooks, lens graft forceps, are used to cut the cornea, assist in removing the cloudy lens, suturing wounds.
