Background: During combined phacovitrectomy, it is common practice to suture the main corneal incision to prevent intraoperative and postoperative wound leak. However, it may be possible to avoid suturing using a self-sealing corneal incision technique as in standard cataract surgery.

Objectives: To evaluate the clinical outcome, safety, and complications of combined phacovitrectomy without preventive suturing.

Methods: This retrospective case series study included consecutive patients who underwent combined phacovitrectomy between January 2018 and June 2019 for mixed indications. Surgeries were performed at a tertiary university hospital. All surgeries were performed by the same two retinal surgeons. Cataract surgery was performed first, followed by insertion of trocars and vitrectomy. Corneal sutures were not planned but were used at the discretion of the surgeon.

Results: The cohort included 106 eyes of 102 patients. Suturing of the main corneal incision was deemed necessary in five cases (5%) because of a main incision leak or anterior chamber shallowing during trocar insertion. No other complications related to the absence of prophylactic corneal sutures were encountered during surgery or follow-up.

Conclusions: Preventive corneal suturing may not be necessary in combined phacovitrectomy surgery and can be used in the few cases in which it is indicated during surgery.

Background: Prolonged life expectancy has increased the number of elderly high risk patients referred for surgical aortic valve replacement (AVR). These referred high risk patients may benefit from sutureless bioprosthesis procedures which reduce mortality and morbidity.

Objectives: To present our initial experience with sutureless aortic bioprotheses, including clinical and echocardiographic results, in elderly high risk patients referred for AVR. 

Methods: Forty patients (15 males, mean age 78 ± 7 years) with symptomatic severe aortic stenosis underwent AVR with the 3F Enable™ or Perceval™ sutureless bioprosthesis during the period December 2012 to May 2014. Mean logistic EuroScore was 10 ± 3%. Echocardiography was performed preoperatively, intraoperatively, at discharge and at follow-up.

Results: There was no in-hospital mortality. Nine patients (22%) underwent minimally invasive AVR via a right anterior mini-thoracotomy and one patient via a J-incision. Four patients underwent concomitant coronary aortic bypass graft, two needed intraoperative repositioning of the valve, one underwent valve exchange due to inappropriate sizing, three (7.5%) had a perioperative stroke with complete resolution of neurologic symptoms, and one patient (2.5%) required permanent pacemaker implantation due to complete atrioventricular block. Mean preoperative and postoperative gradients were 44 ± 14 and 13 ± 5 mmHg, respectively. At follow-up, 82% of patients were in New York Heart Association functional class I and II.

Conclusions: Sutureless AVR can be used safely in elderly high risk patients with relatively low morbidity and mortality. The device can be safely implanted via a minimally invasive incision. Mid-term hemodynamic results are satisfactory, demonstrating significant clinical improvement.
