Traditional Method vs AI. Which Is Better? Barrett Universal Ii or Ladas Super Formula

Pursuing optimal visual outcomes following cataract surgery remains a cornerstone of modern ophthalmology. Central to this objective is the precise calculation of intraocular lens power. However, despite significant advancements in biometric measurements and computational algorithms, variability in refractive outcomes continues to pose a challenge. This study aims to analyse the outcomes comprehensively by reviewing established and newer techniques. The eyes included in the study were evaluated based on various criteria, and a total of 210 eyes which met these criteria were included in the research. Our study is a retrospectively designed observational research study. The study included individuals who had experienced successful IOL implantation to correct refractive errors or cataracts. The ARGOS SS-OCT device is a spectral-domain optical coherence tomography system was used in the study. In measuring the lens power, values were obtained using Barrett Universal II and Ladas Super Formula. These values were compared. Postoperative assessments were conducted at 1-3 months, and 3-12 months, including spherical equivalent. In our study, 210 eyes were examined. The mean age of the participants was 63.44±11.62 years. The study's two most frequently used lens brands were ALCON and ZEISS. The lens powers calculated using the Barrett Universal II and Ladas Super Formula were compared. The means of the two calculations were found to be very close, and no statistically significant difference was observed between them. We compared the spherical equivalent values calculated during the participants' first and second postoperative follow-ups. The spherical equivalent values were similar, with no statistically significant difference. Formulas represent significant advances in ophthalmology and significantly improve visual outcomes; however, differences in their methodology and predictive accuracy warrant further analysis.
