Study type | Observational |
The goal of this retrospective study is to quantify the physiological lens tilt of the phakic eye. The main question it aims to answer is: -What influence does misalignment or tilting of IOLs have on visual quality? Preoperative biometry data are compared with anterior segement OCT data. Measurements were obtained using high-resolution swept-source optical coherence tomography. The influence of biometric measurements on tilt is analyzed.
