Abstract Details

Purpose:

To study the measurement of intraocular pressure (IOP) before and after implantation of intrastromal corneal ring (MyoRing) in patients with keratoconus.

Setting:

Baghiyatallah University of Medical Sciences, Tehran, Iran

Methods:

We compared the IOP of 13 eyes which underwent MyoRing implantation prior and six months post operation using Goldmann applanation (as gold standard), Icare, and Corvis ST (uncorrected, corrected and corrected with cornea biomechanics).

Results:

The resulting intraocular pressure measurements prior to surgery, Icare, Corvis (corrected with cornea biomechanics) overestimated the IOP however measurements by Corvis uncorrected underestimate the IOP. The resulting intraocular pressure measurements after surgery, Icare, Corvis (corrected with cornea biomechanics) overestimated the IOP however measurements by Corvis uncorrected underestimate the IOP

Conclusions:

Consistent intraocular pressure measurements on eyes with Myoring in keratoconus can be obtained with the Goldmann applanation tonometer as the gold standard measurement. We were not able to obtain consistent results when we measured the IOP by Icare and Corvis prior and after surgery.
