Abstract

Background: There are various techniques to improve the safety and effectiveness of phaco surgery, including the capsulorhexis technique using a 30G needle. Objectives: To evaluate the clinical effectiveness and several related factors of phaco surgery with a 30-gauge needle assistance technique to attain a single stage Continuous Curvilinear Capsulorhexis in intumescent cataract. Materials and methods: A prospective, cross-sectional study on 13 patients with intumescent cataracts having indications for phaco surgery from 8/2022 to 4/2023. Results: The average axial length was 23.40 ± 0.86 mm. The average lens thickness is 4.62 ± 0.59 mm. The average anterior chamber depth was 3.13 ± 0.45 mm. The percentage of patients with the milky liquefied cortex was 53.8%. The successful Continuous Curvilinear Capsulorhexis  were l00%. Total phaco energy used was 48.13 ± 6.92% with a total time of 48.58 ± 9.49 seconds. The mean preoperative visual acuity was 2.24 ± 0.23 logMAR increased statistically significantly after surgery at 1 week was 0.15 ± 0.08 logMAR, 1 month was 0.07 ± 0.05 logMAR, and 3 months was 0.06 ± 0.06 logMAR (p<0.001) with 100% of patients having good visual acuity better than 0.16 logMAR (7/10). The difference of astigmatism and intraocular pressure between before and after surgery were not significant (p>0.05). No intraoperative and postoperative complications were noted. Conclusion: Phaco surgery with a 30-gauge needle assistance technique was an effective and safe method in patients of intumescent cataract.
