One hundred and three patients (103 eyes), aged 18 years and above, with nuclear sclerosis (NS)+2, NS +3, +4, cortical, and posterior subcapsular cataracts (WHO Cataract Grading Group) were included, whereas patients with uveitis, glaucoma, traumatic cataracts, small pupils, zonular weakness, lens subluxation, small palpebral fissures, soft cataracts (NS + 1), and posterior polar cataracts were excluded from the study. The stop-and-chop technique was performed in 58 (56.3%) patients, whereas the two-hole-assisted chop technique in the rest. Ultrasound time (UST), total surgical time, and volume of balanced salt solution (BSS) delivered were recorded.<\/jats:p>\n <\/jats:sec>\n \n RESULTS:<\/jats:title>\n \n The mean age of the participants was 65.12 \u00b1 8.85 years. The comparison of the two techniques revealed no statistically significant difference in the UST (\n P<\/jats:italic>\n = 0.723), volume of BSS used (\n P<\/jats:italic>\n = 0.102), and total surgery time (\n P<\/jats:italic>\n = 0.517). However, a significant positive correlation between cataract grade and UST (Spearman\u2019s\n r<\/jats:italic>\n = 0.888,\n P<\/jats:italic>\n < 0.001), BSS volume delivered (Spearman\u2019s\n r<\/jats:italic>\n = 0.831,\n P<\/jats:italic>\n < 0.001), and surgery time (Spearman\u2019s\n r<\/jats:italic>\n = 0.846,\n P<\/jats:italic>\n < 0.001) was observed. Moreover, the UST comparison between cataract grades revealed a significant difference between the three groups (\n F<\/jats:italic>\n = 185.09\n P<\/jats:italic>\n < 0.001).\n P<\/jats:italic>\n < 0.05 was considered statistically significant.\n <\/jats:p>\n <\/jats:sec>\n \n CONCLUSION:<\/jats:title>\n The two-hole-assisted phaco chop is a safe and efficient transitional technique between stop-and-chop and direct-chop techniques for nuclear disassembly in cataract surgery performed by resident surgeons. In addition, the phacoemulsification parameters of the two-hole-assisted chop technique are comparable with the stop-and-chop technique.<\/jats:p>\n <\/jats:sec>","DOI":"10.4103\/sjopt.sjopt_37_24","type":"journal-article","created":{"date-parts":[[2024,6,10]],"date-time":"2024-06-10T02:00:22Z","timestamp":1717984822000},"page":"31-36","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":2,"title":["Comparison between two-hole-assisted phaco-chop and stop-and-chop techniques for nuclear disassembly in residents\u2019 cataract surgery"],"prefix":"10.4103","volume":"40","author":[{"given":"Rehan","family":"Naqaish","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Al-Shifa Trust Eye Hospital, Rawalpindi, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hamzeh M.","family":"Alrawashdeh","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, National University Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rayyan","family":"Sabih","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Al-Shifa Trust Eye Hospital, Rawalpindi, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Syed A.
