Comparison of macular thickness and inflammatory cytokine levels after microincision versus small incision coaxial cataract surgery

INTERVENTION: This prospective randomized study included 84 eyes which were randomly allocated to one of the following two treatments: 1. Phacoemulsification with microincision coaxial cataract surgery (2.2 mm incision) 2. Phacoemulsification with small incision CONDITION: Cataract ; Eye Diseases ; Cataract, unspecified PRIMARY OUTCOME: 1. Intraoperative measurements included:; 1.1. Ultrasound time (UST); 1.2. Mean cumulative dissipated ultrasound energy (CDE); 1.3. Total balanced salt solution (BSS) use; 2. Clinical measurements included preoperative, 1‐week postoperative, 1‐month postoperative and 2‐month postoperative:; 2.1. Best corrected visual acuity (BCVA); 2.2. Central corneal thickness (CCT); 2.3. Endothelial cell count (ECC) SECONDARY OUTCOME: Enzyme‐linked immunosorbent assay (ELISA) and reverse transcription polymerase chain reaction (RT‐PCR) were performed for IL‐1alpha, IL‐6, VEGF and PGE2 preoperatively and at 1 week postoperatively INCLUSION CRITERIA: Eyes with nuclear density from Grade 3 to 4
