Purpose : To evaluate differences in intraocular pressure(IOP) change according to the refractive error, corneal thickness and ablation depth in experienced and inexperienced, soft contact lenses pre LASEK.
Methods : The medical records of 189 eyes of 95 patients who underwent laser assisted epithelial keratomileusis(LASEK) were reviewed. Experienced and inexperienced, soft contact lenses before surgery was classified into two groups, postoperative change in intraocular pressure(IOP) by a month after the conditions were compared.
Results : Experienced and inexperienced, soft contact lenses, after refractive surgery for intraocular pressure(IOP) before and after the change of 12.95±2.60mmHg, 14.20±4.04mmHg from 10.13±2.82mmHg, 11.47±3.55mmHg(p=0.04) in both groups, IOP 2.82±2.81mmHg(p=0.000), 2.74±4.20(p=0.000) fell, but postoperative IOP between the two groups were not different. The preoperative spherical equivalent, corneal thickness, laser corneal ablation amount in both groups
according to postoperative IOP changes of soft contact lenses experienced mild and high myopia group (p<0.05) decrease in the intraocular pressure (IOP) was the difference and laser targeted ablation depth (p=0.00) showed a difference of the IOP decrease in all other conditions except for higher preoperative myopia, corneal thickness and intraocular pressure (IOP) that the greater the amount of ablation, but there was no significant difference between two groups.
Conclusions : There were no difference in intraocular pressure change by soft contact lens experienced group and non-experienced group among the three conditions(ablation amount, thickness, refraction) after LASEK surgery.
