Intraocular pressure measurements after conductive keratoplasty

J Refract Surg. 2005 Mar-Apr;21(2):171-5. doi: 10.3928/1081-597X-20050301-13.

Abstract

Purpose: To determine the possible impact of conductive keratoplasty (CK) on intraocular pressure (IOP) measurements.

Methods: A prospective, single-center, noncomparative interventional case series was performed. Baseline and postoperative IOPs were measured by Goldmann applanation tonometry in 32 eyes of 18 patients who underwent CK for hyperopia correction. Mean follow-up was 11.9 months (range: 8 to 18 months).

Results: After CK, a statistically significant decrease in the measured IOP was observed (before CK: 14.22+/-1.64 vs after CK: 12.66+/-2.21, P<.001). The change in IOP readings postoperatively was not correlated with age, sex, keratometric readings, or attempted correction.

Conclusions: Despite the limitations due to the small number of patients enrolled in this study, the applanation tonometer appears to underestimate the true IOP after CK.
