This patient desires cataract surgery with an extended depth of focus IOL in order to improve his vision. However, at pre-operative testing, he was noted to have bilateral pterygia which were inducing a significant degree of irregular corneal astigmatism. The most accurate way to achieve a precise refractive outcome is to first remove the pterygium and then give the eye a few months to heal. We can then perform the cataract surgery with more accurate biometry and therefore more precision in the refractive outcome. This video shows the technique of using an amniotic membrane graft to cover the sclera and then fibrin based tissue glue to secure everything without using sutures.
