Purpose:
To report a case of a successful secondary Descemet membrane endothelial keratoplasty in failed penetrating keratoplasty. Case summary: A 46-year-old male with keratoconus in both of his eyes underwent penetrating keratoplasty in his right eye 30 years ago and in his left eye 14 years ago. From one and a half year ago, the patient’s visual acuity decreased in his left eye due to graft failure. For treatment, secondary Descemet membrane endothelial keratoplasty was performed. Partial detachment of Descemet membrane was observed at 13 days after the operation, and an additional air injection was performed. At 8 months after the operation, the patient’s uncorrected visual acuity improved to 0.5 and the cornea maintained its clearance without rejection.
Conclusions
Secondary Descemet membrane endothelial keratoplasty was successfully performed in a patient with failed penetrating keratoplasty.

Purpose:
To report a case of Descemet stripping automated endothelial keratoplasty (DSAEK) for graft failure after re-penetrating keratoplasty (PK).Case summary: A 33-year-old man of Indian nationality who had developed right eye amoeba keratitis and had received two penetrating keratoplasties and allogeneic kerato-limbal transplant in India sought treatment at our hospital. During the follow-up, Ahmed valve transplantation was performed under the diagnosis of secondary glaucoma in his right eye; the patient also underwent conjunctival recession and conjunctival permanent amniotic membrane transplantation as corneal neovascularization had progressed. Subsequently, the corneal transplantation failed and DSAEK was performed. At 7 months after the operation, the right-eye visual acuity was 20/320 without any complications.
Conclusions
DSAEK may restore good vision without complications in patients with repeated corneal graft failure after PK from corneal endothelial cell failure followed by corneal neovascularization and glaucoma surgery but with good stromal conditions. We present this case, along with a review of the literature. Future studies will require more surgical patients.

Purpose:
To report a case of secondary Descemet membrane endothelial keratoplasty (DMEK) for graft failure after primary DMEK.Case summary: A 47-year-old female underwent primary DMEK in her left eye with a diagnosis of Fuchs’ endothelial dystrophy. At 6 weeks later, corneal stromal edema with epithelial and subepithelial bullae was first observed. From that point on, the condition of the cornea and the visual acuity continued to degrade. After 7 months, a second DMEK procedure (i.e., a repeat DMEK) for graft failure was performed successfully without any complications. Since the second procedure, the cornea has been clear, and the best-corrected visual acuity has remained at 0.6 for 8 months.
Conclusions
To manage graft failure after primary DMEK, we performed a second DMEK procedure. The removal of the previous graft was easy, and there were no complications. Thus, repeat DMEK may be a feasible procedure.

After 5 years, she complained of decreased vision; graft failure was observed. Secondary DMEK was performed; no additional air injection was needed. The corrected visual acuity was 0.2, 3 months after surgery, and the cornea became clear.
Conclusions
Visual recovery can be achieved by performing secondary DMEK after primary DSEK graft failure.

PTEN hamartoma tumor syndrome is a spectrum of disorders characterized by unique phenotypic features including multiple hamartomas caused by mutations of the tumor suppressor gene PTEN. Cowden syndrome and Bannayan–Riley–Ruvalcaba syndrome are representative diseases, and both have several common clinical features and differences. Because PTEN mutations are associated with an increased risk of malignancy including breast, thyroid, endometrial, and renal cancers, cancer surveillance is an important element of disease management. We report a germline mutation of the PTEN (c.723dupT, exon 7) identified in a young woman with a simultaneous occurrence of breast cancer, dermatofibrosarcoma protuberans, and follicular neoplasm. This case suggests that it is critical for clinicians to recognize the phenotypic features associated with these syndromes to accurately diagnose them and provide preventive care.

PURPOSE: We report the clinical manifestations of dry eye syndrome after cataract surgery involving meibomian gland structure, meibomian gland function, and tear lipid layer analysis. METHODS: The clinical manifestations of dry eye syndrome were retrospectively evaluated in 34 eyes of 31 patients who underwent cataract surgery from September to November 2017. The ocular surface disease index (OSDI), tear break-up time (tBUT), Oxford stain score, presence or absence of blepharitis, and meibomian gland expression were measured preoperatively and at 1 week, 1 month, and 2 months postoperatively. Lipid layer thickness (LLT), partial blinks, and meibomian gland images were measured using LipiView® (TearScience, Morrisville, NC, USA), an interferometric eye surface measuring device. RESULTS: The postoperative OSDI was significantly higher than preoperative OSDI (17.09 ± 1.81): 22.76 ± 1.99 at 1 week, 23.12 ± 1.91 at 1 month, and 22.68 ± 1.92 at 2 months (p < 0.05). The postoperative tBUT was significantly lower than preoperative tBUT (5.07 ± 0.39): 3.99 ± 0.31 at 1 week, 3.49 ± 0.27 at 1 month, and 4.72 ± 0.39 at 2 months (p < 0.05). The Oxford staining score increased after surgery, but the difference was not statistically significant. Postoperative meibomian gland expression was significantly lower preoperative values (4.9 ± 2.8): 4.4 ± 2.8 at 1 month, and 3.9 ± 2.8 at 2 months (p < 0.05). The LLT decreased at 1 month postoperatively and increased at 2 months postoperatively, but these differences were not statistically significant. CONCLUSIONS: Cataract surgery resulted in a short-term meibomian gland dysfunction, leading to deterioration of dry eye after cataract surgery. However, we could not confirm structural changes in the meibomian gland, so it will be necessary to observe the clinical features of dry eye syndrome over a longer period of time.
