A limited but favorable effect of transepithelial CXL was noted on keratoconic eyes, without complications. The effect appears to be less pronounced than described in the literature after CXL with de-epithelialization.

Despite 2 complicated cases, intraoperative perforation during DALK had a good final functional prognosis. However, eyes in which the perforation required reformation of the anterior chamber had a mean endothelial cell loss greater than 20%. When air is left in the anterior chamber, close monitoring is required to avoid pupillary block.

Refractive lens exchange in keratoconic eyes predictably corrected myopia. However, ultrasound biometry was inaccurate in almost one third of eyes. Intraoperative autorefractometry is recommended to improve refractive outcome.

An inflammatory presentation is not uncommon in orbital lymphoid tumors. Shape, molding and multiple masses can help radiological diagnosis, whereas MRI T2 intensity is unreliable. Accurate staging can disclose systemic disease in more than 50% of cases of non-Hodgkin lymphoma.

PRK with MMC can safely and effectively correct myopia and regular myopic astigmatism after DALK. Undercorrection should be planned to compensate for the overcorrecting effect of MMC.
