A well-sized and properly centered capsulorhexis is essential for achieving optimal outcomes in phacoemulsification cataract surgery, yet digital guidance systems that improve precision are not widely available in many settings. To address this gap, a study evaluated whether manual marking–assisted capsulorhexis (MMAC) is noninferior to digital guidance–assisted capsulorhexis (DGAC) in terms of capsulorhexis accuracy following phacoemulsification for age-related cataract in 156 adults.
The study found that median deviations between the capsulorhexis and target diameters were 0.22 mm vs 0.27 mm for horizontal diameter and 0.27 mm vs 0.33 mm for vertical diameter in the MMAC and DGAC groups, respectively, both within the noninferiority margin of 0.20 mm. The proportion of ideal capsulorhexis was 96.2% (75/78) in the MMAC group compared with 88.5% (69/78) in the DGAC group, meeting the…
