Materials and Methods: Medical records of participants that underwent combined PPV and PKP surgery with TKP for severe eye trauma were retrospectively analysed. During the follow-up, functional success (best corrected visual acuity (BCVA)) remained the same or increased, and anatomic success (retinal reattachment, graft transparency) and complications were evaluated.
Results: Twenty-two eyes of 22 patients (mean age 43.40±22.43 years, 15 male/7 female) were included in this study. The mean follow-up period was 12±7.8 months. At the last follow-up, BCVA increased in 3 patients (13.6%) and remained unchanged in 16 patients (72.7%). Two of 3 patients had decreased BCVA with LogMAR chart from 2.10 to 3.10 logMAR, while 1 patient had decreased from 3.10 logMAR to loss of light sensation (13.6%). At the last follow-up, the retina was attached in 16 patients (72,8%). Corneal graft remained transparent during follow-up in 12 patients (54.5%), while graft failure was seen in 10 eyes (45.5%).
Conclusion: PPV and PKP surgery combined with TKP is an alternative method for patients with corneal opacities that not allowed to vitrectomy. Although retinal reattachment is achieved in the majority of patients, corneal graft failure is a common postoperative complication. Patients should be informed about the long-term functional outcomes of this complicated surgery.
