Late Descemet Membrane Detachment After Uneventful Cataract Surgery

Purpose: To report 5 patients with late Descemet membrane (DM) detachment after uneventful cataract surgery. Observations: After a retrospective chart analysis of consecutive patients that developed DM detachment after uneventful cataract surgery, six eyes of five patients were enrolled. In all cases, patients reported good vision initially after cataract surgery. Within days to months, these patients developed late DM detachment with decreased vision. In one patient, the detachment affected both eyes. Filtered air or diluted sulfur hexafluoride were injected in the anterior chamber to tamponade the DM detachment. In five eyes, the cornea cleared after DM reattachment. In two eyes of the same patient, DM reattached spontaneously requiring no further surgical intervention. In one patient, the Descemet failed to reattach and required an endothelial keratoplasty. Conclusion and importance: Descemet membrane detachment may occur after uneventful cataract surgery. Filtered air or long-lasting intraocular gas may be used to reattach DM. Spontaneous DM reattachment may also occur and surgeons should be aware of this to avoid unnecessary procedures

Efficacy of Eyesi surgical simulator training in improving high-tension capsules capsulorhexis performance

ABSTRACT Purpose: To evaluate if Eyesi cataract surgical simulator training using its standard course curriculum is effective in improving performance of cataract surgery trainees on creating capsulorhexis on high-tension capsules on the simulator. Methods: We retrospectively analyzed training reports of ophthalmic surgery trainees (2nd and 3rd year residents and cataract fellowship trainees) that have accomplished the standard Eyesi cataract surgery simulator training course version 2.1 between May 2012 and August 2013 at Instituto de Diagnostico e Terapia Ocular, Rio de Janeiro, Brazil. We compared the mean score (from 0 to 100) attributed by the simulator on performing the same task, a capsulorhexis on a high-tension capsule, on the surgical simulator "before training" (during beginning of the course) and "after training" (at later stages of the course). Results: Thirty-seven trainees' reports were analyzed. Mean and standard deviation "before training" high-tension capsulorhexis score was 41.73 ± 27.08 points and the mean "after training" score was 72.55 ± 16.40 points, a difference of +30.82 points (p value <0.001 on Paired t test), representing a 73% improvement on performance. Conclusions: Eyesi surgical simulator training on course version 2.1 curriculum was effective in improving performance of cataract surgery trainees on creating capsulorhexis on high-tension capsules
