Objective. To analyze postoperative visual functions, refractive and keratometric changes in eyes after cataract extraction. Materials and methods. During 2013 and 2014 were analyzed 299 eyes after cataract phacoemulsification and implantation with IOL in Lithuanian Health Sciences University Eye Clinic. Visual acuity, refractive, keratometric and biometric measurments were analyzed preoperatively and at least 1 month after the surgery. MS excel and SPSS statistical programs were used to calculate the data. P<0.05 was considered significant. Results. The best corrected visual acuity improved from 0.20±0.18 before the surgery to 0.78±0.22 after the surgery (p<0,001). Visual acuity of 0.5 and better was achieved for 87.9 percent patients. A postoperative refraction between – 0.5 D and +0.5 D was achieved in 54.2 percent patients, – 1.0 D and +1.0 D in 80.9 percent patients. The mean of corneal astigmatism after the surgery was 1.05 ± 0.97 D with the prevalence of against the rule astigmatism. Surgically induced astigmatism was 0.42±0.52 D. Conclusions. In this study we found markedly improvement of best corrected visual acuity after cataract surgery (0.78±0.22). 80.9 percent of patients achieved postoperative refraction between – 1.0 D and +1.0 D. Surgically induced astigmatism was 0.42±0.52 D. These findings indicate satisfactory outcomes following cataract surgery.
