Purpose
To evaluate the tilting and decentration of sutureless scleral-fixated IOLs using anterior segment OCT (AS-OCT), specifically comparing the Carlevale IOL and the 3-piece IOL implanted with the Yamane technique.
Setting
A retrospective monocentric study conducted at Beauregard Hospital (Aosta), AUSL Valle d’Aosta, Italy.
Methods
Consecutive patients who underwent sutureless scleral-fixated IOL implantation (Carlevale and Yamane techniques) between January 2023 and December 2023 were included. Six months post-surgery, AS-OCT imaging (Casia2, Tomey) was performed to measure IOL tilting and decentration.
Results
A total of 33 eyes from 33 consecutive patients were evaluated with AS-OCT. Of these, 19 eyes had undergone 3-piece IOL fixation using the Yamane technique, while 14 eyes had Carlevale IOL fixation. The mean tilting in the Yamane group was 6.9° compared to 6.4° in the Carlevale group (p=0.59). In terms of decentration, the mean values were 0.61 mm in the Yamane group and 0.48 mm in the Carlevale group (p=0.23).
Conclusion
The analysis revealed no statistically significant differences in tilting and decentration between the two techniques. However, a trend toward lower decentration was observed with the Carlevale IOL compared to the Yamane technique. Overall, in this limited sample, the mean values for tilting and decentration obtained with AS-OCT were clinically acceptable and low in magnitude, reaffirming the high precision and reliability of both approaches.
