Abstract

Objectives: Efficacy of the srk/t formula for intraocular lens calculation at nghe an eye hospital. Methods: Descriptive prospective study enrolled 162 eyes of patients with cataract that underwent phacoemulsification at the nghe an eye hospital from 11/2022 - 3/2023.  Residual refractive error at 1 weeks, 1 month and 3 months after surgery was reported. The achieved refractive error at 3 months was compared to the predicted postoperative refractive error by the SRK/T formula. Results: The mean residual equivalent spherical and spherical refraction of the whole study group were 0.35 ± 0.11 and 0.44 ± 0.1 respectively. The average spherical refraction and equivalent spherical refraction of the sediment study group over time, after 3 months, the residual refraction fluctuates within ± 0.50D. Results after 1 week, equivalent spherical refraction from +0.50 → -0.50D had 111 eyes (68.5%) accounting for the highest percentage, after 1 month and 3 months, this ratio increased to 72.8, respectively. % and 77.8%. After 1 week, most of the postoperative visual acuity without glasses was over 20/70, accounting for 90.1%, vision with glasses reaching over 20/70, accounting for 93.3%. After 1 month and 3 months, the rate of stability is 90.7% of distance vision without correction and 95.1% of distance vision with correction
