Purpose

visualization of the posterior segment pathologies during vitreoretinal surgeries is crucial in providing a more efficient and safer surgical outcome.
We aim to evaluate the clinical profile, complications, anatomic and visual outcomes of eyes that underwent combined pars plana vitrectomy (PPV) and penetrating keratoplasty (PK) in one session using a temporary keratoprosthesis (TKpro).

Setting

one armed retrospective cohort case series 

Methods

This was a retrospective review of the medical records at King Khaled Eye Specialist Hospital from June 2014 to December 2022 of all patients who underwent PPV and corneal transplantation in a single surgical occasion using TKpro. We were interested to look at and analyze the following demographics, ocular history, preoperative assessment, concurrent surgical procedures performed, preoperative and postoperative visual acuities, complications, and final anatomic outcomes. Patients with a minimum follow-up of 3 months were included.

Results

A total of 44 eyes of 44 patients enrolled in this study. The mean follow-up period was 52.01±42.26 months (range: 1.31-148.83). The primary indications for PK were as follows: 14 cases traumatic corneal scar (31.8%), 11 cases failed previous PK (25%), 8 cases corneal edema (18.2%), 4 cases corneal scar (9.1%). While the primary indication for PPV was mainly retinal detachment (RD) without proliferative vitreoretinopathy (PVR) in 20 cases (45.5%) and RD with PVR in 10 cases (22.7%). Corneal graft failure occurred in 25 transplants (56.8%) during the follow-up. The retina remained attached until the last follow up in 35 (79.6%) eyes.

Conclusions

Poor visual prognosis despite high rate of reattached retina credited to the prior tissue damage or underlying ocular comorbidities. A careful patient selection and enhance patient counseling about the long-term potential for this type of surgery is important to avoid unwanted complication.
