Capsulotomy describes the opening of the lens capsule during this surgery and is most commonly performed by manual tearing, thermal cutting, or laser ablation. This work focuses on the development of a flexible instrument for high precision capsulotomy, whose motion is controlled by a hybrid mechanical-magnetic actuation system. Methods: A flexible instrument with a magnetic tip was directed along a circular path with a hybrid mechanical-magnetic actuation system. The system\u2019s motion control and thermal cutting behavior were tested on ex vivo porcine lenses. Results: Position control of the magnetic tip on a circular path with radius of 2.9[Formula: see text]mm resulted in a relative positioning error of 3% at a motion period of 60[Formula: see text]s. The instrument\u2019s accuracy improves with decreasing speed. A fully automated capsulotomy is achieved on an ex vivo porcine lens capsule by continuously coagulating the tissue under controlled conditions. Conclusions: Robot assisted capsulotomy can be performed with excellent precision in ex vivo conditions. <\/jats:p>","DOI":"10.1142\/s2424905x18500010","type":"journal-article","created":{"date-parts":[[2017,11,1]],"date-time":"2017-11-01T04:50:07Z","timestamp":1509511807000},"page":"1850001","source":"Crossref","is-referenced-by-count":7,"title":["A Robotic Diathermy System for Automated Capsulotomy"],"prefix":"10.1142","volume":"03","author":[{"given":"Franziska","family":"Ullrich","sequence":"first","affiliation":[{"name":"Multi-Scale Robotics Lab, ETH Zurich, Tannenstrasse 3, 8092 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3241-8164","authenticated-orcid":false,"given":"Jonas","family":"Lussi","sequence":"additional","affiliation":[{"name":"Multi-Scale Robotics Lab, ETH Zurich, Tannenstrasse 3, 8092 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vasileios","family":"Chatzopoulos","sequence":"additional","affiliation":[{"name":"Multi-Scale Robotics Lab, ETH Zurich, Tannenstrasse 3, 8092 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephan","family":"Michels","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, City Hospital Triemli, Zurich, Birmensdorferstrasse 497, 8063 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew J.","family":"Petruska","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Colorado School of Mines, 1610 Illinois St., Golden CO 80401, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bradley J.","family":"Nelson","sequence":"additional","affiliation":[{"name":"Multi-Scale Robotics Lab, ETH Zurich, Tannenstrasse 3, 8092 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2018,2,8]]},"reference":[{"key":"S2424905X18500010BIB003","doi-asserted-by":"publisher","DOI":"10.1038\/eye.1995.119"},{"key":"S2424905X18500010BIB004","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9394(03)00226-5"},{"key":"S2424905X18500010BIB005","first-page":"1","author":"Raviv T.","year":"2009","journal-title":"Cataract Refract.
