Puis-je effectuer CXL dans mon bureau ?
Qu'en est-il du risque infectieux ?
Remember that every cross-linking procedure not only improves biomechanics, it also ?disinfects? the cornea by directly killing all micro-organisms and by inhibiting cellular replication. This is why a cornea at the end of every CXL and PACK-CXL procedure is ?sterile?. And by the way: office-based cataract surgery et office-based intravitreal injections have been performed in many thousands of cases without increased infection risk.
Le temps n'est-il pas trop long ?
Irradiation time is not too long. Current modern protocols are integrated in the C-eye device and treat in as little as 10 minutes (CXL) and 4 minutes (PACK-CXL). See the published approach ici.
CXL fonctionne-t-il en position assise ?
We need 3 elements for successful cross-linking: UV light, oxygen and riboflavin. Both UV light and oxygen do not ?care? whether the patient is laying down or sitting. As for riboflavin, published research shows that riboflavin concentration is stable in the upright position for up to 60 minutes - much longer than we need for a CXL treatment.
Le patient est-il confortable ?
Offer the patient the comfortable surgeon?s chair with the armrest and take the extra time to ensure that the patient is well-adjusted. Then, the patient is very comfortable.
Qu'en est-il de la fixation du patient ?
Fixation is no issue. Offer the patient the fixation target that most slit lamps offer (for retinal examination) and the patient will keep a very steady fixation, as you can see ici.
