Case Study – Corneal Toxic Keratopathy (CTK)

Mr M A, a 45 year old managing director wanted to be free of spectacles and contact lenses. He has worn contact lenses for last 13 to 14 years but started having issues when swimming and travelling. He also began to notice changes to his near vision.

Initial Examination:

Corneal Toxic Keratopathy Case Study

Corneal Toxic Keratopathy Case Study 2

The consultation showed the patient to have healthy eyes, a straight forward myopic prescription, with a slight amount of astigmatism and early presbyopia, making him completely suitable for LASIK surgery.

Bilateral Wavefront Intralase LASIK was performed on 10.07.2015 without any complications.

This was not a normal case of DLK and therefore suspicious of bilateral Corneal Toxic Keratopathy (CTK). Further testing was carried out, including OCT and confocal microscopy.
