Intraocular pressure measurement after corneal transplantation

Measurement of intraocular pressure is an integral part of a comprehensive ocular examination, especially after a surgical intervention that can affect aqueous humor flow dynamics. Most of the intraocular pressure measurement devices are designed for normal corneas and may not be accurate in eyes after corneal transplantation where there is altered corneal morphology. Raised intraocular pressure and glaucoma are known postoperative complications after transplantation, and therefore, accurate intraocular pressure measurement is essential. We review the effect of abnormal corneal curvature, corneal thickness, and different biomechanical properties in the context of corneal transplantation on intraocular pressure measurement using a number of devices.
