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: Reports from Europe and North America indicate that significant changes have occurred in the practice of cardiac surgery in the last two decades.

Objectives: To examine the trends and case-mix in cardiac surgery in Israel and their relationship with changes in invasive cardiology.

Methods: We analysed data collected by the Ministry of Health from all cardiac centers in Israel from 1985 to 2002.

Results: Three periods were identified: the 1980s, when a relatively small number of operations were performed; 1990–1994, characterized by a dramatic rise in the number of operations; and 1994–present, characterized by a small decline and stabilization in the rate of operations. The percentage of valve procedures increased significantly from 15% of all cardiac surgeries in 1991 to 21% in 2002 (P = 0.002). In addition, the chance of a diagnostic coronary angiography being followed, in the same patient, by an interventional procedure such as percutaneous transluminal coronary angioplasty or by a coronary artery bypass graft increased dramatically from 42% in 1991 to 69% in 2002. At Rabin Medical Center, there was a constant decline in the percent of repeated CABGs[1] out of the total CABGs performed, from 6.7% in 1996 to 1.3% in 2002.

Conclusions: Despite the rise in the rate of percutaneous coronary interventions since 1991, there has been no significant decline in the rate of CABGs performed. However, there is a significant shift to more complex operations. The number of repeated CABG operations has significantly decreased and, in view of the growing use of arterial grafts and further improvements in invasive cardiology techniques, we expect this decline to continue.

Background: Eyes scheduled for posterior segment surgery may have cataract, which obscures the visualization of the retina. Surgery may be carried out either by a two-step procedure: i.e., removal of the cataract followed later by posterior segment surgery; or it may be done in a single session: i.e., combined surgery of both the anterior and posterior segments.

Objective: To evaluate the outcomes of combined surgery by phacoemulsification and vitrectomy.

Methods: We retrospectively reviewed the records of 42 patients with coexisting cataract and vitreoretinal disease who underwent combined surgery by phacoemulsification and pars plana vitrectomy at one session.

Results: Indications for surgery were vitreous hemorrhage in 71.4%, retinal detachment in 11.9%, macular hole in 11.9%, and epiretinal membrane in 4.8%. There were no significant intraoperative complications.The main early postsurgical complications were fibrinous formation in 11.9%, elevated intraocular pressure in 23.8%, and recurrent vitreous hemorrhage in 9.5%. There were a few late complications related to phacoemulsification: posterior synechia in 9.5%, posterior capsular opacification in 7.1%, and dislocating intraocular lens in 4.8%. Recurrent retinal detachment occurred in five eyes and rubeoisis iridis in one. Visual acuity was improved in 85.8%, stable in 7.1% and worse in 7.1%.

Conclusions: Phacoemulsification performed at the time of posterior segment surgery enables good visualization during the vitrectomy, facilitates surgery, and is associated with only minor complications. In cases with cataract and vitreoretinal diseases, combined surgery by phacoemulsification and vitrectomy in one session may be considered.
