Purpose: The 2.2-mm microincision cataract surgery and small-gauge vitrectomy system is known to result inless surgically-induced astigmatism (SIA) in comparison to conventional surgical methods. We compared theamounts of SIA after combined phacoemulsification and 23-gauge transconjunctival sutureless vitrectomy(23G-TSV) using the 2.2-mm microincision and 2.75-mm standard incision methods. Methods: We studied 59 patients (61 eyes) who underwent combined phacoemulsification and 23G-TSV fromNovember 2008 to September 2012. Twenty-eight patients (28 eyes) underwent 2.2-mm microincision coaxialphacoemulsification, and 31 patients (33 eyes) underwent 2.75-mm standard incision phacoemulsification. SIAwas evaluated using Naeser’s polar method with the simulated keratometric values obtained from corneal topography. Preoperative and 1-week and 1-month postoperative KP (Naeser’s polar value along the specific axis) andΔKP values were compared between the 2.2-mm microincision and 2.75-mm standard incision groups. Results: One week after surgery, both groups exhibited similar amounts of SIA (-ΔKP[120], 0.40 ± 0.41 vs. 0.51± 0.56 diopters [D]; p = 0.390). One month after surgery, however, the amount of SIA was significantly smallerin the 2.2-mm microincision group as compared to the 2.75-mm standard incision group (-ΔKP[120], 0.31 ± 0.54vs. 0.56 ± 0.42 D; p = 0.045). Conclusions: In combined phacoemulsification with 23G-TSV, 2.2-mm microincision coaxial phacoemulsificationinduces less SIA than does 2.75-mm standard coaxial phacoemulsification.
