Abstract Details


To investigate the complications of modern phacoemulsification cataract surgery in highly myopic eyes previously undergone pars plana-vitrectomy.


Moorfields Eye Hospital, London,United Kingdom


Eyes with axial length ≥26.0 mm undergoing standard phacoemulsification cataract surgery at Moorfields Eye Hospital (London-UK) during the study periods were eligible if they had previously undergone pars plana vitrectomy. As controls, highly myopic eyes with no history of previous surgery were studied. Eyes with history of blunt or penetrating ocular trauma and previous or combined anterior segment surgery were excluded from studied and control groups. Outcome measures were: rates of severe intraoperative adverse events, severe postoperative complications, and critical patient safety incidents.


Consecutive notes of 87 eyes were reviewed. During the same time period, 516 highly myopic eyes had phacoemulsification cataract surgery (used as control). Experienced ophthalmic surgeons carried out the vast majority of the surgical procedures in both series (88.4% and 94.3%, respectively). Mean axial lengths and anterior chamber depths were similar among the 2 series (P=0.157 and P=0.634,respectively). The rate of posterior capsule rupture was 2.30% (versus 0.97% in the control series), no other severe intraoperative adverse events were observed. No critical patient safety incidents were documented, with a single case of severe postoperative complication.


Although both the investigated variables have been regarded as independent risk factors for increased intraoperative complications at the time of phacomeulsification cataract surgery in the past, our study demonstrated that experienced surgeons operating on this specific subgroup of patients can achieve rates of capsule complications similar to average.
