Development Of A Surgical Instrument Prototype To Perform A More Precise Capsulorhexis, Kirk Haugen
Interdisciplinary Program Research
Performing capsulorhexis is often considered the most difficult part of cataract surgery. Not only is it difficult to perform, but doing it correctly is important for refractive outcomes (Okada, Hersh, Paul, & Straaten, 2013). Poorly done capsulorhexes are associated with problems including posterior capsulor opacification, capsulor fibrosis, and capsulor phimosis (Raviv, The perect capsulorhexis: more critical than ever, 2010). This study investigates whether or not a proposed surgical instrument will produce more precise capsulorhexes as measured by the circularity index. 60 capsulorhexes were performed on cigarette paper laid over clay. Half were done using the continuous curvilinear capsulorhexis method, while …
