Abstract Details

Purpose:

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

Setting:

Retrospective, cross-sectional study

Methods:

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.

Results:

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.

Conclusions:

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.
