Performing capsulorhexis is often considered the most difficult part of cataract surgery. Not only is it difficult, but performing it correctly is important for refractive outcomes.4 Inaccurate capsulorhexes are associated with complications including posterior capsular opacification, capsular fibrosis, and capsular phimosis.6 This study investigates the possibility of a proposed surgical instrument producing more precise capsulorhexes as determined by the circularity index. 60 capsulorhexes were performed on cigarette paper laid over clay - half using the continuous curvilinear capsulorhexis (CCC) method, and half using the proposed instrument. The precision of the capsulorhexis was then measured using the circularity index. The capsulorhexes cut with the proposed instrument were more precise than the current method, suggesting the adoption of the instrument may lead to better refractive outcomes in patients.
