Sirius Cutting Mode enhances vision and reduces myopia severity through personalized treatment

To assess the reliability of vision correction for presbyopia using the Sirius Cutting Mode and its effect on visual acuity, corneal mechanics, and high-order aberrations over time.

This retrospective study analyzed data from 150 presbyopic patients. Of these, 74 received personalized vision correction using the Sirius Cutting Mode, while 76 served as controls with no presbyopia treatment. Participants were selected from a predefined database based on strict inclusion and exclusion criteria. Data on spherical equivalent, visual acuity, stereo testing, eye mechanics, and high-order aberrations were collected at baseline and at the end of the follow-up period. Multivariate regression analysis was conducted to identify factors influencing near visual acuity outcome.

The treatment group demonstrated significant improvements in uncorrected distance visual acuity (UDVA) and near visual acuity (NVA) at all follow-up intervals compared to the control group (both P < 0.001). Additionally, the treatment group showed a significant reduction in myopia, with lower spherical equivalent values at 10 days, 1 month, 3 months, and 6 months (all P < 0.001). High-order aberrations were significantly reduced, and corneal biomechanical properties, including maximum deformation amplitude and maximum deformation curvature radius, and improved at 6 months (all P < 0.001). Multivariate analysis identified the Sirius Cutting Mode as a significant predictor of NVA outcomes (P < 0.001).

The Sirius Cutting Mode with personalized treatment results in improved vision for both near and far distances, reduced myopia severity, and decreased higher-order aberrations in presbyopic patients.
