Corneal Thickness Factors and Intraocular Pressure

We thank Dr Lempert for his interest and comments concerning our article.1 We agree with him that central corneal thickness may influence the results of applanation tonometry. However, although refractive surgery can alter central corneal thickness and affect subsequent intraocular pressure (IOP) measurements, such evidence is not present for filtration surgery in which there is no actual manipulation of the cornea. In contrast, no significant relationship was found between trabeculectomy and central corneal thickness in patients with glaucoma.2
