A Study on Repeatability and Agreement of Keratometry & Refractive Prediction between Verion and IOL Master
Kaksha Desai, Riddhi Shah
Abstract: Purpose: The aimed to analyse the predictability of the instrument for calculation of IOL power and K reading on VERION planner and to check the verion predicted refractive power or final follow - up refractive power. Methodology: From March 2020 to July2021, a retrospective investigation was done at the Rotary Eye Institute in Navsari. The study included 120 eyes, both preoperatively and postoperatively, from people who had cataract surgery (phacoemulsification). The patients were assessed on both machines by the same examiner during each individual pre - assessment, and then followed up on the VERION image - guided system as well as the IOL master roughly 2 months after surgery by the same examiner. The calculation for the predictive spherical outcomes for both the IOL Master and VERION systems. Then both IOL Master IOL power and verion IOL power and the VERION Predicted refractive power and after final follow up refractive power were compared using SPSS software. Result: Pre - operative IOL K1 (43.42 ? 1.94) was almost same significantly (p<0.01) VERION K1 value (43.42 ? 1.94). Pre - operative IOL K2 (43.31 ? 2.07) was significantly same as the VERION K2 (43.40 ? 2.07). Pre - operative VERION predicted refractive status (SPH & CYL) in 2.2mm incision ( - 0.15 ? 0.12) ( - 0.70 ? 0.54) was decreases (- 0.04 ? 0.20) (- 0.49 ? 0.60) significantly after Final follow - up. Pre - operative VERION predicted refractive status (SPH & CYL) in 2.8mm incision (- 0.18 ? 0.11) (- 0.93 ? 0.56) was decreases ( - 0.07 ? 0.21) ( - 0.88 ? 0.96) significantly after Final follow - up. Pre - operative VERION predicted refractive status (SPH & CYL) in 3.0mm incision (- 0.17 ? 0.10) (- 0.76 ? 0.54) was decreases (-0.13 ? 0.33) (- 0.88 ? 0.96) significantly after Final follow - up. The correlation between two (IOL master 500 & VERION) for determining pre - operative keratometry reading demonstrated a high relationship between the pre - operative K1 of IOL master & VERION (p<0.01, r=0.975) and pre - operative K2 of IOL master & VERION (p<0.01, r=0.981). The correlation between (IOL master, VERION and IOL implanted power) demonstrated a medium relationship between the IOL master power and VERION power (p<0.01, r=0.679) & a high relationship between the IOL master and IOL implanted power (p<0.01, r=0.954) & a high relationship between the VERION and IOL implanted power (p<0.01, r=0.748). Conclusion: After the two months final follow - up the Sph&Cyl power are decreased then the VERION predicted refractive power but the cylinder power was almost same as the VERION predicted power. The analysis suggests that there was a statistically correlation between IOL master and VERION.
