Purpose: To evaluate the efficacy of a cloud-based surgical planning platform with regards to refractive target accuracy.
Methods: This was a retrospective chart review of consecutive cases from January 2022 through December 2023. Surgical planning was performed using the SMARTCataract platform, eyes were implanted with Clareon monofocal IOLs, and power calculations were done using the Barrett Universal II formula. Data were collected for the percentage of eyes within ±0.5 D of target refraction, mean absolute error (MAE), and postoperative visual acuity.
Results: A total of 148 eyes were identified that met the inclusion/exclusion criteria. The percentage of eyes within ±0.5 D of the planned target was 94%. The MAE was 0.25 ± 0.17 D. In addition, 57%, 93%, 98%, and 100% of eyes had MAE ≤ 0.25 D, ≤ 0.5 D, ≤ 0.75 D, and ≤ 1.0 D, respectively.
Conclusion: The results of this study suggest high refractive accuracy when using the SMARTCataract planning platform with the Barrett Universal II formula and excellent distance visual acuity.

When the natural lens inside the eye develops a cataract (becomes opaque) it can be replaced with a clear artificial intraocular lens (IOL). Good visual outcomes after surgery are heavily reliant on implanting the optimal lens power. A new cloud-based surgical planning tool (SMARTCataract) aims to automatically use patient data, surgeon preferences, favored IOL power calculation formulas, and desired IOL type to guide surgical planning. However, to date there are no data on the refractive outcomes when using the SMARTCataract platform. The purpose of this study was to evaluate the efficacy of the SMARTCataract platform with regards to refractive target accuracy. The results of this study suggest high refractive accuracy when using the SMARTCataract platform with the Barrett Universal II formula and excellent distance visual acuity.
