Cataracts remain the leading cause of blindness in our country and globally. Cataract surgery has a high success rate in improving visual acuity. Objective: This study aimed to analysis and assess clinical findings of Visual acuity before and after surgery for patients who underwent Cataract surgery. Patients and methods: A cross-sectional study was conducted on 75 patients who participated in visual acuity assessments conducted in different hospitals in Iraq between 4 April 2022 and 19 August 2023. The study evaluated visual acuity before and after cataract surgery in patients aged between 50 and 70 years. Results: Our study found that males had a higher rate of cases with 60% than females with 40%, 45% of the patients developed by obesity; most comorbidity prevalence in the patients were posterior subcapsular opacity, which had 45 cases, operative time, min was 15-30 minutes per eye, postoperative days until follow-up was 22. 6 ± 8.42, cylindrical reading, dioptres were - 1.13 ± 0.94, spherical reading, dioptres were - 0.12 ± 3.68, no complications were 90.67%, while the most common complication in patients after surgery was posterior capsular tear and anterior capsular tear. In terms of visual acuity after surgery, Unaided was 0.24 ± 0.21, BCVA was 0.08 ± 0.19, Pinhole was 0.12 ± 0.14, and Best was 0.09 ± 0.14, Visual acuity variations include loss 6/9 < VA < 6/24 had 4 cases, 6/24 < VA < 6/60 had 2 cases, 6/60 < VA had only one case, while gain had 68 cases. Conclusion: The study revealed that following surgery, visual acuity exhibited a notable improvement in patients with lens opacity. This observation has prompted questions regarding the efficacy of a 20/60 level for acuity enhancement.
