ABSTRACT
ObjectiveTo predict the fluctuating intervals of intraocular pressure readings in mild and medium myopia after photorefractive keratectomy(PRK).MethodsThe intraocular pressure(IOP)readings of 383 eyes,of which spherical equivalent were less than-6.0 diopters(D)before and over 1 a after PRK,were measured with noncontact tonometer(NCT).The IOP data were analyzed with paired-sample t test,linear correlation and regression.Regression equation was used to predict the fluctuating intervals of IOP readings after PRK.ResultsThe IOP readings after PRK(10.38±2.08)mmHg were lower than those before PRK(15.43±2.74)mmHg.The difference of IOP readings between before and 1 a after PRK was significant (P<0.001).The postoperative IOP readings were related to those of preoperation (r=0.625,P<0.001)and the regression equation was Y=0.474X+3.064[X=IOP reading before PRK(mmHg),Y=IOP reading followed over 1 a after PRK(mmHg)].If IOP reading before PRK was X0,the 95% tolerant interval of IOP readings followed over 1 a after PRK was 0.5X0-0.1,0.5X0+6.3(mmHg).ConclusionIOP readings before PRK can be used to predict the fluctuating intervals of IOP readings in mild and medium myopia after PRK.
