Evaluation of preoperative data and post-operative results of phacotrabeculectomy in minimum five-year follow-up

ABSTRACT

Objective:

To evaluate the results of phacotrabeculectomy in a follow-up of five years or more.

Methods:

Retrospective, interventional and analytical study that was carried out in the surgical center of clínica de olhos do juazeiro with patients operated on from 2006 to 2013. 34 eyes of 29 patients with senile cataract and primary open-angle glaucoma, who underwent phacotrabeculectomy were involved in the investigation. A risk score for glaucomatous dam-age ranging from 0 to 5 when evaluating intraocular pressure, excavation of the optic disc, number of hypotensive drugs used to treat glaucoma and the patient's age in years. The sample was of convenience and paired. The paired Wilcoxon test was used to verify differences be-tween means. P <0.05 was accepted for the rejection of the null hypothesis. The study was approved by the ethics committee of the Brazil platform and follows the principles of resolu-tion 466 of the National Health Council.

Results:

The mean visual acuity was significantly higher after a five-year follow-up (preoperative average 0.42 +/- 0.23 versus postoperative average 0.62 +/- 0.29 - p = 0.0031). The average risk score for glaucomatous damage after five years of follow-up was significantly lower when compared to the preoperative (preoperative mean: 9.47 +/- 1.61 versus postoperative mean 6.55 +/- 2, 21) p <0.0001, considered extremely significant.

Conclusion:

Phacotrabeculectomy was significantly effective in improving visual acuity and reducing the risk of glaucomatous damage after a five-year postoperative follow-up.
