Advancements in ray-tracing refractive surgery technology

Overview

Recent developments in ophthalmology highlight the growing role of ray-tracing technology in improving the precision of refractive and cataract-related surgeries.

Research presented at the American Academy of Ophthalmology suggests that patients experiencing visual distortions, such as halos or faded colors after cataract surgery, may benefit from minor laser corrections guided by ray-tracing rather than a second cataract procedure. This technology maps light paths to assess the alignment between the cornea and implanted lenses.

Further advancements focus on personalized visual experiences for complex refractive errors. The ‘PersonalEYES’ solution uses ray-tracing to create a ‘Digital Eye Twin,’ a 3D model that simulates light paths to calculate customized ablation profiles. Additionally, clinical comparisons involving the SMILE Pro procedure have shown higher accuracy in correcting astigmatism compared to standard SMILE surgery, specifically reducing residual astigmatism and under-correction rates.
