“…These devices have been shown in the literature to allow all maneuvers without leaking any fluids during surgery. 8,9,10 This technique is also recommended for the subacute management of massive ocular traumas. 11 It has been found superior to other methods because it allows closed-system surgery, wide-angle stereoptic vision, and bimanual surgery.…”

Objectives:To evaluate the clinical results of combined pars plana vitrectomy (PPV) with Landers wide-field temporary keratoprosthesis and penetrating keratoplasty (PK).Materials and Methods:From January 2016, traumatic eyes with coexisting corneal and vitreoretinal diseases that underwent combined keratoprosthesis/PPV/PK surgery were retrospectively evaluated. Demographic characteristics, visual acuity (VA), intraocular pressure (IOP) and clinical findings of the cornea, lens, and retina were recorded during the follow-up. Cases with clear corneal graft, attached retina, normotonic IOP, and improved or stable VA were considered successful.Results:Eight eyes were enrolled in the study. The mean follow-up time was 21.1±8.20 months. Surgery was performed a mean of 23 (10-40) days after trauma. Preoperative VA ranged from no light perception to counting fingers from 50 cm. Postoperatively, corneal graft was clear in 5 patients (62.5%) and retina was attached in 6 eyes (75%). Chronic hypotonia developed in 3 patients (37.5%). VA was unchanged in 3 patients and improved in 5 patients. A total of 5 cases (50%) were considered successful. Shorter interval between trauma and surgery was associated with higher likelihood of success (p=0.043). No significant difference was observed between the groups in terms of type or location of trauma (p=1; p=0.143).Conclusion:Although the functional results are not very satisfactory, the combined procedure provides a final opportunity for preserving remaining vision and anatomic reconstruction in eyes that will otherwise result in phthisis due to severe anterior and posterior segment pathologies.

Purpose: To assess the long-term outcomes of combined penetrating keratoplasty (PKP) and pars plana vitrectomy (PPV). Methods: A retrospective review of eyes that underwent combined surgery followed for 12 months or longer. Demographic data, indications for surgery, and pre-/post-surgical eye examinations were retrieved. Results: Thirteen consecutive eyes (13 patients) were enrolled. The mean age was 51.5 ± 20.5 years, and the mean follow-up time was 67 ± 36.9 months. All cases had severe corneal opacity. Indications for surgery included retinal detachment (76.9%), dropped lens (7.7%), dropped intraocular lens (7.7%), and endophthalmitis with corneal abscess (7.7%). Visual acuity improved in 46.1% of the cases, though in most cases visual acuity remained low, and decreased in 23% of the cases. In 23% of the cases (3 eyes), ambulatory vision was achieved for more than 12 months and in 15.4% for three years. Silicone oil tamponade was used in all cases of retinal detachment (10 eyes). Of these eyes, at the final follow-up, four eyes were attached, two eyes were partially attached, and corneal opacity prevented retinal visualization in three eyes. One eye was eviscerated and one eye developed phthisis. Postoperatively, 61.5% of the cases underwent repeated PKP for graft decompensation. At the final visit, graft failure was observed in 75% of the cases. Conclusions: The long-term follow-up of eyes that underwent combined PKP and PPV supports this technique in complex cases for eye and vision preservation. The main problem after combined surgery is the long-term survival of the corneal graft which may require repeated PKP surgeries. With this approach, in 23% of the cases, ambulatory vision was maintained for more than 12 months.
