PURPOSE: To evaluate the effect of mild to moderate myopic correction by laser-assisted in situ keratomileusis (LASIK) on intraocular pressure (IOP) measurements with three tonometers: the Goldmann applanation tonometer, Tono-Pen, and pneumatonometer. PATIENTS AND METHODS: In a prospective study of a clinic-based population undergoing elective LASIK surgery for myopia correction, IOP measurements were obtained pre- and postoperatively with a Goldmann applanation tonometer, Tono-Pen, and pneumatonometer. Central corneal thickness and keratometric and astigmatism measurements were also obtained before and after surgery. A paired t test was used to evaluate the significance of differences between pre- and postoperative IOP measurements with each instrument. Linear regression was used to correlate IOP measurements with degree of myopia corrected, astigmatism, and central corneal thickness before and after surgery.
