Purpose:
|
The goal of this study was to compare differences in the mean hetrophoria and fusional amplitudes before and after photorefractive keratectomy (PRK) for myopia.
|
Methods:
|
In a prospective controlled study, myopic patients were treated with aspheric and wavefront-guided (personalized) PRK with a Bausch & Lomb Technolas 217z excimer laser. The manifest refraction, visual acuity, fusional amplitudes and hetrophoria were evaluated preoperatively and at 3 and 6 months postoperatively. Fusional amplitudes were measured at far (6 meters) and near (40 centimeters) by rotary prism and hetrophoria was evaluated by Maddox wing.
|
Results:
|
A total of 48 cases (96 eyes, 68.75% female) were treated, with a mean age of 26.70 ± 4.89 years (18–34 years).In the fusional reserves, comparisons between preoperative and 6 months postoperative means showed that far and near base out recovery points were changed significantly. In hetrophoria measurements, contrary to the rest of the deviations, exophoric deviation was increased, but not significantly (p = 0.063).
|
Conclusion:
|
Findings of this study imply that far and near base out reserves were changed significantly postoperatively. The other fusional reserves were similarly decreased 3 months postoperatively and returned to the preoperative values at 6 months.
