Sub-1 Millimeter—700 Micron Cataract Surgery

Abstract

We have reviewed the surgical technique, advantages, and limitations of sub-1 mm–700 micron cataract surgery or ‘microphakonit.’ The small clear corneal incision is made with the 0.8 mm microphakonit knife and the instruments, such as the phacoemulsification needle, irrigating chopper, and bimanual irrigation aspiration set, are made with a 0.7 mm diameter. We have also reviewed some of the work done by the authors in 700 micron cataract surgery and our analysis of microphakonit wound architecture has been explained. The clear corneal wound architecture in microphakonit has been evaluated with anterior segment optical coherence tomography and the healing process has been assessed. The microphakonit has proven to have early wound healing and less post-operative astigmatism as compared with the wound with extension.
