Abstract
Purpose :
To evaluate refractive change after trabeculectomy.
Methods :
We prospectively evaluated refractive changes of 97 patients who underwent trabeculectomy. The primary outcome measure was the refractive change after trabeculectomy. Secondary outcome measures included postoperative complications and prognostic factors for refractive change.
Results :
The refraction progressed myopic shift significantly by -0.80 diopter at 12 months after surgery. In the phakic eyes, the refraction progressed myopic shift significantly by -0.46 diopter at 3 months after surgery (P = 0.003), -0.52 diopter at 6 months (P = 0.012), and -1.31 diopter at 12 months (P <0.001). In the pseudophakic eyes, no significant progression of refraction was found at any post-surgery follow-up visits. In multivariable analyses, the change of nuclear color grade of the lens was a significant prognostic factor for refractive myopic progression (P <0.001).
Conclusions :
Trabeculectomy causes refractive myopic progression in phakic eyes. The nuclear sclerotic cataract progression is associated with refractive myopic shift after trabeculectomy.
