Abstract

PURPOSE: To investigate the structural changes of anterior chamber after photorefractive keratectomy in myopic eyes, we assessed the changes of anterior chamber(AC) depth, angle and correlations with ablation depth at sixth postoperative month.
METHODS
We performed photorefractive keratectomy on 77 eyes of 40 patients and divided them into 3 groups by the degree of preoperative myopia; less than -4.0 diopter, between -4.0 and -6.0 diopter and greater than -6.0 diopter. We assessed the changes of AC depth and angle using Scheimpflug camera(EAS-1000, Nidek, Japan) after 6 months.
RESULTS
The average preoperative AC depth and angle were 3.59+/-0.27 mm, 44.20+/-2.58 and 3.53+/-0.27 mm, 43.29+/-1.65 at sixth postoperative month. The reductions in AC depth and AC angle were statistically significant(P<0.05), and there were no differences among three myopia groups(P>0.05). The changes of both AC depth and AC angle were not affected by ablation depth(P>0.05).
CONCLUSIONS
Structural changes of anterior chamber were significant 6 months after photorefractive keratectomy and the changes were not affected by degree of myopia nor by ablation depth.
