Comparative evaluation of the efficiency of astigmatism correction methods in cataract surgery

The purpose of the study was to compare the effectiveness of methods of astigmatism correction in the surgical treatment of cataract. Material and Methods. Analysis of 157 cases (eyes) of surgical treatment of cataract with concomitant astigmatism was carried out, of which 131 eyes were operated using the ARKUATA method and 26 were operated using the TORIKA method. The age of patients ranged from 40 to 72 years. Results. As a result of the study we obtained statistically substantiated data, which showed that there were no objective differences in the compared methods for correcting corneal astigmatism: the formation of arcuate relaxing incisions and the use oftoric lOLs. Using the classification tree method, a model for predicting positive effect of the outcome of an operation with a value of un-corrected visual acuity of 1.0 was built. Conclusion. Both methods, in the absence of complications, can correct corneal astigmatism with the same statistical probability, allowing to achieve an uncorrected visual acuity of 1.0. However, from an economic point of view, the cataract surgery is most optimally performed using toric lOLs, as the cost of this treatment is 29.83% lower than when using femtosecond technologies.
