[Underestimation of intraocular pressure after laser in situ keratomileusis].
OBJECTIVE
We reviewed 115 eyes of 65 patients regarding the intraocular pressure(IOP) following laser in situ keratomileusis(LASIK).


METHODS
The ages averaged 31.2 +/- 10.5(mean +/- standard deviation) years. The preoperative spherical equivalent averaged -6.85 +/- 2.54 (mean +/- standard deviation) D. A noncontact pneumatic tonometer and Goldmann applanation tonometer were used in measuring the IOP.


RESULTS
The IOP difference before and after surgery was statistically significant(Mann-Whitney U test). The IOP was significantly corrected with the corrected diopter value, corneal thickness, and corneal curvature(Spearman coefficient by rank).


CONCLUSIONS
The findings show that postoperative IOP may be underestimated due to decreased corneal thickness and curvature. Due attention has to be paid to this feature in evaluating IOP after LASIK.
