Abstract Details

Purpose:

To analyze the type of intraoperative complications in cataract surgery performed by resident ophthalmology doctors (ROD) and their frequency during the training period, comparing it with each other and with expert surgeons

Setting:

Hospital Universitario de la Princesa, Madrid, Spain. Universidad Autonoma de Madrid, Spain.

Methods:

Retrospective comparative study of 6,097 surgeries performed between 2008-2018. The rate of intraoperative complications including iris damage, anterior capsule tear, posterior capsule rupture, vitreous loss, Descemet membrane tear, dropped nucleus or vitreous haemorrhage were analyzed for all training and expert surgeons. The presence of previous ocular risk factors including white cataract, pseudoexfoliation, corneal opacities, previous vitrectomy, small pupil/floppy iris syndrome were analyzed.

Results:

The main complications were: iris prolapse 4.84% (CI 4.31-5.40); posterior capsule rupture (PCR) 2.56% (IC 2.17-2.98) and vitreous haemorrhage 1.61%; (IC 1.30-1.95). By groups: PCR: ROD1 7.39%, ROD2 4.34%, ROD3 3.03%, ROD4 2.81%; dropped nucleus fragment: 1.56%, 0.84%, 0.39% and 0.35% respectively (p <0.05). For senior adjuncts: dropped nucleus fragment 0.25%; vitreous haemorrhage 1.29%; PCT 1.66%. The presence of risk factors was associated with an increase in PCT OR 2.93% (CI 1.86-4.60), dropped nucleus fragment OR 3.07% (CI 1.04-9.09) and iris prolapse OR 8.02% (CI 6.11-10.51).

Conclusions:

As they progress in their training, residents have lower rates of complications.The most frequent being: iris prolapse, posterior capsular tear and vitreous haemorrhage. The presence of risk factors implies an increased risk of posterior capsule tear, iris prolapse and dropped nucleus fragment.
