Purpose
To determine the preoperative biometric parameters obtained with a Heidelberg ANTERION that can feasible predict postoperative vault in ICL implantation.
Setting
CODET Vision Institute, Tijuana, Baja California, Mexico.
Methods
This study included 102 eyes of 57 patients implanted with ICL V4c for correction of myopia and astigmatism. Anatomical measures were obtained with swept-source optical coherence tomography (SS-OCT) ANTERION (Heidelberg Engineering, Heidelberg, Germany). Biometric parameters analyzed and correlated with postoperative vault were mean keratometry (K), central corneal thickness (CCT), white to white (WTW), anterior chamber depth from corneal endothelium (AQD, lens thickness (LT), axial length (AL), horizontal angle to angle (ATA) and spur to spur (STS) distance as well as anatomical position of the crystalline lens using the crystalline lens rise (CLR) and lens vault (LV). Postoperative central vault was evaluated 6 weeks after the surgery.
Results
A total of 91 eyes of 52 patients implanted with 12.6 and 13.2 mm Visian ICL V4c were included in the final analysis. For univariate and bivariate data analysis the 12.6 mm and 13.2 lens sizes were treated as independent groups. For the 12.6 mm lens size, the vault was positively correlated with the AXL (p <0.001). For the 13.2 mm lens size the vault was positively correlated with the AQD (p = 0.014), and AXL (p = 0.009), and negatively correlated with the CLR and LV (p < 0.001). On multivariate lineal regression (MLR) analysis AQD (p = 0.16), STS distance (p = 0.03), and LV (p = 0.004) were found as the best predictors for postoperative vault according to the different ICL sizes and a predictive model was addressed with these parameters.
Conclusions
Preoperative anatomical measures obtained with SS-OCT Heidelberg Anterion showed strong correlation with postoperative vault after ICL implant and predictive formulas can be addressed based in high-resolution anterior segment imaging with this platform.
