Efficiency of modified hydrodissection vs traditional method in age related cataract surgery: a randomized clinical trial

Abstract

Abstract Purpose To investigate whether our modified hydrodissection is safe and efficient in age related cataract surgery. Methods A prospective, randomized, single-blind clinical study was performed in Chongqing Bishan Old Town Hospital from May 16 to August 31, 2022. Age related cataract patients without any other ocular disease were included. They were randomly allocated into modified hydrodissection and traditional hydrodissection groups. Hydrodissection was performed using modified or traditional method. It kept the same procedures as routine in incision, continuous circular capsulorhexis, phacoemulsification, irrigation-aspiration. Hydrodissection time and Oscar score are the main measurement to evaluate the efficiency of the modified method. Descemet membrane detachment, unstable anterior chamber and posterior capsular rupture were the main measurements to evaluate the safety. Results There were 156 patients (age:71.39 ± 7.17 years old; gender: 90 (57.7%) female, 66(42.3%) male) with age related cataract participating in this study. The hydrodissection time was 12.23 ± 1.84s and 18.72 ± 1.69s in the modified hydrodissection group and traditional group, respectively (P༜.001). 89.7% of eyes in modified hydrodissection group achieved Oscar score 5, which was achieved by only 75.6% eyes in traditional group (P = .033). There was no complication occurred in these patients. Conclusions This study demonstrated that the modified hydrodissection was as safe as traditional method but with more efficiency.
