To determine the influence of phacoemulsification on choroidal vasculature in patients with diabetic retinopathy (DR) undergoing cataract surgery using swept-source optical coherence tomography (SS-OCT). Methods. The study was conducted in 23 eyes of 23 cataract patients with mild\/moderate nonproliferative diabetic retinopathy (NPDR) without diabetic macular edema (DME) and 23 age-matched controls. Choroidal thickness (CT) and choroidal vascularity index (CVI) were measured at baseline and 1 week, 1 month, and 3 months after surgery. Results. The baseline CVI in the DR group was significantly lower than that in the control group (<jats:inline-formula>\n                     <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mi>P<\/a:mi>\n                        <a:mo>=<\/a:mo>\n                        <a:mn>0.001<\/a:mn>\n                     <\/a:math>\n                  <\/jats:inline-formula>). CVI in DR patients after surgery significantly increased compared with preoperative values (all <jats:inline-formula>\n                     <c:math xmlns:c=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\">\n                        <c:mi>P<\/c:mi>\n                        <c:mo>&lt;<\/c:mo>\n                        <c:mn>0.001<\/c:mn>\n                     <\/c:math>\n                  <\/jats:inline-formula> for 1 week, 1 month, and 3 months after surgery). Postoperative increase of CVI and CT in the DR group was more than in the control group, and the difference was significant 1 month and 3\u2009months after surgery (all <jats:inline-formula>\n                     <e:math xmlns:e=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M3\">\n                        <e:mi>P<\/e:mi>\n                        <e:mo>&lt;<\/e:mo>\n                        <e:mn>0.05<\/e:mn>\n                     <\/e:math>\n                  <\/jats:inline-formula>). Conclusion. Patients with mild\/moderate NPDR have reduced CVI compared with nondiabetic patients at baseline; diabetic cataract surgery tended to induce more increase in CVI and CT as compared with nondiabetic patients.
