Abstract:
To evaluate croneal haze related to amount of correction, age and sex following excimer laser photorefractive keratectomy(PRK) in myopic eyes, 39months follow-up study on 358 eyes was performed prospectively. The preoperative spherical equivalent refraction ranged from -1.0D to 11.25D(mean -6.18D). The subjective corneal haze grading showed a maximum with mean grading of 0.92 at 2 months and a gradual decrease to 0.14 at 24 months after PRK. The degree of haze was statistically greater with higher amount of correction(p<0.05). No difference was found related to age and sex(p>0.05). Clinically significant corneal haze and scarring was frequent in higher myopia group(p<0.05). Individual variation in corneal haze after PRK was found. However, high myopia is a risk factor of the corneal haze following PRK, and further study to decrease the corneal haze after PRK is necessary.
