Intraocular pressure after LASIK for hyperopia.
OBJECTIVE
To determine whether hyperopic laser in situ keratomileusis (H-LASIK) affects Goldmann applanation tonometry measurements.


METHODS
Retrospective, comparative, self-controlled case series.


METHODS
One hundred eight eyes of 58 patients were enrolled in the study.


METHODS
Baseline intraocular pressure (IOP) was measured by Goldmann applanation tonometry. These readings were compared with readings obtained at least 6 months after surgery.


RESULTS
After H-LASIK, a decrease was observed in the measured IOP of treated eyes that could not be related to the degree of hyperopia treated or to the treatment zone diameter. A significant difference was observed between the IOP before and after surgery (P < 0.00001).


CONCLUSIONS
The applanation tonometer underestimates the true IOP after LASIK for hyperopia.
