Intraocular pressure measurement after hyperopic and myopic LASIK.
OBJECTIVE
To assess the effects of hyperopic and myopic laser in situ keratomileusis (LASIK) on the intraocular pressure (IOP) measurement by Goldmann applanation tonometry.


METHODS
Intraocular pressure was measured by Goldmann applanation tonometry pre- and postoperatively in 48 hyperopic eyes (26 patients) and 56 myopic eyes (28 patients).


RESULTS
The mean preoperative spherical equivalent refraction was +3.97 +/- 2.48 diopters (D) in the hyperopic group and -6.73 +/- 4.79 D in the myopic group. Attempted correction was equivalent to preoperative refraction in each group. Mean preoperative IOP was 14.22 +/- 2.56 mmHg and 13.70 +/- 2.09 mmHg in the hyperopic and myopic groups, respectively. Following LASIK, the mean IOP was 11.85 +/- 2.52 mmHg and 11.38 +/- 3.08 mmHg in the hyperopic and myopic groups, respectively.


CONCLUSIONS
The IOP measurement was significantly reduced (P < .001) by 2.37-2.25 mmHg and 2.32 +/- 2.89 mmHg following hyperopic and myopic LASIK, respectively.
