Purpose
To investigate how angle alpha and angle kappa influence refractive accuracy, visual outcomes, and patient satisfaction following implantation of a full-range vision intraocular lens (IOL) with an AI-engineered spiral optic design.
Setting
Dunya Goz Hospital Group, Istanbul, Türkiye
Methods
A total of 60 patients who underwent cataract or refractive lens exchange with an AI-designed spiral optic IOL were analyzed. Key evaluation criteria included monocular and binocular uncorrected visual acuity at distance (UDVA), intermediate (UIVA), and near (UNVA), as well as residual refractive error and patient-reported visual quality. The association between preoperative angle alpha and kappa with postoperative visual and refractive performance was examined.
Results
The mean values for angle α and angle κ were 0.43 ± 0.24 mm and 0.36 ± 0.20 mm, respectively. Both angles were predominantly positioned temporally in relation to the visual axis. Statistical analysis did not demonstrate a significant correlation between these parameters and postoperative refractive accuracy or visual function. Most patients attained favorable uncorrected vision across multiple distances and reported high levels of satisfaction with their visual experience.
Conclusions
Preoperative measurements of angle alpha and kappa did not have a statistically meaningful impact on postoperative refractive precision, visual clarity, or patient-reported satisfaction in individuals receiving an AI-designed spiral optic IOL. These parameters should be considered as part of a comprehensive assessment rather than a standalone criterion for patient selection.
