Purpose

To analyze the tilt and decentration of Carlevale IOL in eyes without capsular support using second-generation swept-source anterior segment optical coherence tomography (AS-OCT). Indeed, significant IOL tilt and decentration can induce astigmatism and higher-order aberrations, leading to visual disturbances​.

Setting

This retrospective multicenter study was conducted at the following three centers in Italy:

  • Beauregard Hospital, Aosta Valley (AUSL Valle d'Aosta)
  • IRCCS Azienda Ospedaliera-Universitaria, Alma Mater Studiorum University of Bologna
  • Piero Palagi Hospital, Florence (AUSL Toscana Centro)

Methods

Consecutive patients who underwent sutureless scleral-fixated Carlevale IOL implantation between January 2023 and December 2023 were included. At six months post-surgery, AS-OCT imaging (Casia2, Tomey) was performed to measure IOL tilt and decentration through an automatic software. This eliminates the need for operator-dependent post-processing of images to calculate IOL tilt and decentration. However, all images were reviewed and manually adjusted when the surface of the IOL was misrecognized by auto-detection. IOL tilt was defined as the angle between the IOL axis and the line connecting the fixation point to the corneal apex, while IOL decentration was defined as the linear distance between the IOL center and the reference axis.

Results

A total of 63 eyes from 63 patients (29 male and 34 female) implanted with Carlevale IOL were included. The mean patient age was 71,2 years. The mean tilt was 5,81°and the mean IOL decentration was 0,49 mm.

Conclusions

To the best of our knowledge, this is the largest study assessing Carlevale IOL tilt and decentration using second-generation swept-source AS-OCT. In this cohort, the values for IOL tilt and decentration obtained with AS-OCT were clinically acceptable and low in magnitude, reaffirming the high precision and stability of sutureless scleral-fixated Carlevale IOL.
