. Purpose: To investigate and compare the long‐term subjective and objective visual functional results of phacoemulsification in diabetics and non‐diabetics. Methods: A prospective, longitudinal, population‐based study comprising 57 diabetics and 473 non‐diabetics, who had cataract surgery during a 1‐year period at Norrlands University Hospital, Umeå, Sweden. Visual acuity data, visual function questionnaire (VF‐14) responses, and level of diabetic retinopathy were recorded pre‐ and postoperatively as well as 5 years after surgery. Results: Four months postoperatively, the median VF‐14 total score for both the diabetics and the non‐diabetics was 100; at 5 years, the score decreased to 96.4 and 97.2, respectively (p = 0.81). The median best corrected visual acuity (BCVA) of the operated eye was logMAR 0.046 (Q1:Q3 = 0:0.15) for both the diabetics and the non‐diabetics 4–8 weeks postoperatively. Five years later, the BCVA for the diabetics was logMAR 0.14 (Q1:Q3 = 0.02:0.34) and for the non‐diabetics 0.1 (Q1:Q3 = 0.02:0.3), (p = 0.34). Five years after surgery, 26% of the diabetics and 22% of the non‐diabetics had a reduction in VF14‐score of 10 points or more (p = 0.64) compared with 4 months postoperatively. One‐third of both the diabetics (18/57) and the non‐diabetics (149/473) had lost more than 0.1 log MAR unit in BCVA of the operated eye (p = 0.86). Conclusion: Subjective and objective visual function 5 years after cataract surgery remained stable in most surviving diabetics and non‐diabetics. The longitudinal visual function in diabetics was not significantly worse compared with non‐diabetics.
