Isaac Porter, MD discusses options to control astigmatism that may occur after a corneal transplant in this episode of A State of Sight. As explained in episode #7 of A State of Sight (Astigmatism...): • Astigmatism, toric lens, corneal curv... astigmatism is an uneven curvature of the cornea. • Corneal transplants including penetrating keratoplasty (PKP) and deep anterior lamellar keratoplasty (DALK) replace the central part of the cornea which is the clear covering over the front of the eye. These grafts are attached with sutures around the circular transplant to hold it in place. As time passes, wound healing occurs and the sutures can be removed, usually from 6 months to two years or later after the operation. This wound healing can be unpredictable and cause changes in the curvature of the cornea, creating astigmatism. • Fortunately, this astigmatism can be managed with glasses, toric contact lenses, and rigid gas permeable contact lenses. However, if the amount of astigmatism is greater than these lenses will correct, surgical options may be considered. • It is possible to create incisions in the cornea to lower the amount of astigmatism or relax the wound between the transplant and the host cornea. Also, additional sutures can be placed at the same time in a different location to steepen the cornea in that area and help to balance the astigmatism. The excimer laser that is used for LASIK and PRK can be very accurate in treating astigmatism and may be used following corneal grafts in patients who are good candidates. • Have any questions about astigmatism or how astigmatism can be treated after corneal transplantation?
