Uncorrected distance visual acuity (UCDVA) and refractive astigmatism measurements were obtained, with an average follow-up of 4 weeks.Results: The average preoperative cylinder was similar (0.61 D in the femtosecond group [n=124] and 0.57 D in the conventional group [n=100] (P> 0.05)). More patients had ≤ 0.5 D of postoperative corneal astigmatism in the femtosecond group (n=110/124, 89%) than in the conventional group (n=71/100, 71%), respectively (P=0.001). The mean absolute postoperative refractive astigmatism was higher in the conventional surgery group than in the femtosecond group (0.43 ± 0.4 D vs 0.26 ± 0.28 D); these differences were statistically significant (P< 0.001). The percentage of patients with UCDVA of 20/20 or better vision was higher in the femtosecond group (62%) than the conventional group (48%) (P=0.025).Conclusion: Using the femtosecond laser for arcuate incisions in combination with a novel nomogram can provide excellent anatomic and refractive outcomes in patients with lower levels of preoperative astigmatism at the time of cataract surgery.Keywords: femtosecond laser-assisted cataract surgery, arcuate incision, visual acuity, refractive outcome, corneal astigmatismWortz GGupta PKGoernert PHartley CWortz BChiu JJaber NDove Medical Pressarticlefemtosecond laser-assisted cataract surgeryarcuate incisionvisual acuityrefractive outcomecorneal astigmatismOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 14, Pp 2229-2236 (2020)
