Abstract Details


To investigate the impact of fixation stability on refractive error after cataract surgery in high myopic eyes.


Retrospective, cross-sectional study


The clinical records of 98 consecutive high myopic patients who underwent cataract surgery were reviewed. Demographic data, axial length (AXL), and corneal curvature were analyzed. Refractive error was calculated 1 month after surgery. Fixation stability was evaluated using the MAIA microperimeter system, which assessed the fixation pattern in terms of 63% and 95% of the bivariate contour ellipse area (BCEA). Multiple linear regression analysis was performed to identify independent predictors of postoperative refractive error.


Postoperatively, 56.1% (55/98) of the patients had a hyperopic shift of ≥ 0.5 diopters (D), and 25.5% (25/98) had a hyperopic refractive error of ≥ 1.0 D. The 63% and 95% BCEA ranged from 0.1 to 8.7 deg2 and from 0.4 to 26.2 deg2, respectively. The factors 63% or 95% BCEA were positively correlated with the postoperative refractive error (r = 0.383, P < 0.001 and r = 0.320, P = 0.002, respectively). Multiple linear regression analysis showed that postoperative refractive error in high myopic patients was significantly correlated with AXL, 63% BCEA, and corneal curvature.


High myopic eyes usually had hyperopic refractive error after cataract surgery. Fixation stability might serve as an important determinant of postoperative refractive error in this population.
