Obtaining a pristine cornea the very next day in a hard cataract is a dream far from reality. Prechop means nuclear division without the use of phaco energy. In this article, we describe a prechopping technique using a new sickle-shaped (saber tooth curvature and tip) novel prechopper that has a slender, sleek, and elegant design well suited for nuclear disassembly. The novel prechopper has proved to be a wonder device for hard, soft, white, posterior polar, and exfoliation cataracts. All maneuvers of prechop are performed in the bag away from the endothelium to be easily emulsified, subsequently making phacoemulsification easier, faster, and safer.<\/jats:p>","DOI":"10.4103\/ijo.ijo_2792_23","type":"journal-article","created":{"date-parts":[[2024,5,22]],"date-time":"2024-05-22T03:00:50Z","timestamp":1716346850000},"page":"1369-1371","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Dr. Sohel Khan\u2019s prechopper and prechopping technique"],"prefix":"10.4103","volume":"72","author":[{"given":"Sohel I M","family":"Khan","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Dr S C Government Medical College, Nanded, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2024,5,20]]},"reference":[{"key":"R1-20260427","doi-asserted-by":"crossref","first-page":"1551.","DOI":"10.21037\/atm-2019-rcs-04","article-title":"The history of cataract surgery: From couching to phacoemulsification","volume":"8","author":"Leffler","year":"2020","journal-title":"Ann Transl Med"},{"key":"R2-20260427","doi-asserted-by":"crossref","first-page":"1360","DOI":"10.1016\/j.jcrs.2012.04.025","article-title":"Complication rates of phacoemulsification and manual small-incision cataract surgery at Aravind Eye Hospital","volume":"38","author":"Haripriya","year":"2012","journal-title":"J Cataract Refract Surg"},{"key":"R3-20260427","first-page":"69","article-title":"Phaco prechop: Manual nucleofracture prior to phaco-emulsification","volume":"1","author":"Akahoshi","year":"1998","journal-title":"Op Tech Cataract Ref Surg"},{"key":"R4-20260427","doi-asserted-by":"crossref","first-page":"307.","DOI":"10.1016\/j.jcjo.2014.03.017","article-title":"RE: Ultrachopper tip","volume":"49","author":"Escaf","year":"2014","journal-title":"Can J Ophthalmol"},{"key":"R5-20260427","doi-asserted-by":"crossref","first-page":"564","DOI":"10.1016\/j.jcrs.2012.02.001","article-title":"Middle prechop: Fracturing the middle portion of the nucleus","volume":"38","author":"Berger","year":"2012","journal-title":"J Cataract Refract Surg"},{"key":"R6-20260427","doi-asserted-by":"crossref","first-page":"176","DOI":"10.1136\/bjophthalmol-2017-311766","article-title":"Microinterventional endocapsular nucleus disassembly: Novel technique and results of first-in-human randomised controlled study","volume":"103","author":"Ianchulev","year":"2019","journal-title":"Br J Ophthalmol"},{"key":"R7-20260427","doi-asserted-by":"crossref","first-page":"199","DOI":"10.1080\/08941939.2017.1391358","article-title":"A prechop technique using a reverse chopper","volume":"32","author":"Zhao","year":"2019","journal-title":"J Invest Surg"},{"key":"R8-20260427","doi-asserted-by":"crossref","first-page":"1053","DOI":"10.3928\/1081597X-20091117-04","article-title":"Initial clinical evaluation of an intraocular femtosecond laser in cataract surgery","volume":"25","author":"Nagy","year":"2009","journal-title":"J Refract Surg"},{"key":"R9-20260427","doi-asserted-by":"crossref","first-page":"1431","DOI":"10.4103\/ijo.IJO_730_17","article-title":"Comparative analysis of endothelial cell loss following phacoemulsification in pupils of different sizes","volume":"65","author":"Maggon","year":"2017","journal-title":"Indian J Ophthalmol"},{"key":"R10-20260427","doi-asserted-by":"crossref","first-page":"862.","DOI":"10.1016\/j.jcrs.2017.04.029","article-title":"On the proinflammatory effect of femtosecond-laser assisted cataract surgery in diabetic retinopathy and its possible consequences on postoperative visual outcomes","volume":"43","author":"Hanhart","year":"2017","journal-title":"J Cataract Refract Surg"}],"container-title":["Indian Journal of Ophthalmology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/IJO.IJO_2792_23","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,13]],"date-time":"2026-08-13T18:53:54Z","timestamp":1786647234000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/IJO.IJO_2792_23"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,5,20]]},"references-count":10,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2024]]}},"URL":"https:\/\/doi.org\/10.4103\/ijo.ijo_2792_23","relation":{},"ISSN":["0301-4738","1998-3689"],"issn-type":[{"value":"0301-4738","type":"print"},{"value":"1998-3689","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,5,20]]},"assertion":[{"value":"2023-10-18","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-02-02","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
