Frequency of Complications During Preparation of Corneal Lamellae Used in Posterior Lamellar Keratoplasty Using the Pneumodissection Technique (Big Bubble)

Conclusions: We identified higher endothelial cell density, shorter DPT, and the presence of corneal scars after cataract surgery as risk factors threatening successful bubble formation. The only risk factor for creating type II bubbles was higher donor age in our study.

Conclusions: The FS laser-assisted KLAL technique can produce ring-shaped grafts with an even depth and width, resulting in a stable ocular surface and good visual prognosis. After surgery, glucocorticoids and potent immunosuppressive eye drops were administered locally with concentration gradients and effectively inhibited acute immune rejection.

This study prospectively evaluated the use of ripasudil in patients undergoing DSO for FD. Methods: Enrolled patients underwent DSO with or without cataract surgery, performed by 1 surgeon. On the first postoperative day, patients were assigned to topical ripasudil 0.4% (Glanatec) 4 times a day for 2 months or no ripasudil and followed up monthly for the first 6 months and then at 9 and 12 months after surgery. Endothelial cell density (ECD) and pachymetry were evaluated at each postoperative visit. Results: Eighteen patients were enrolled, including 8 women and 1 man in each group. Overall, patients who underwent DS...

Authors: Yamaguchi T, Higa K, Tsubota K, Shimazaki J Abstract Purpose: Primary graft failure after corneal transplantation is caused by dysfunction of corneal endothelial cells. Recently, we demonstrated that preoperative recipients' aqueous cytokine levels are associated with rapid corneal endothelial cell loss after corneal transplantation. In the present study, we evaluated the preoperative inflammatory cytokine levels in the aqueous humor (AqH) of eyes with primary graft failure following corneal transplantation. Methods: Among the prospective consecutive case series (273 eyes), this study included patients...

I met ophthalmologist and corneal specialist Dr. Peter Polack while speaking in Ocala, Florida. He told me that, by having his patients with dry eye—which has increased dramatically over the last 20 years—remove all wheat and grains, he is seeing this condition reverse within weeks, along with all the other health benefits. Unlike other ophthalmologists, who virtually have nothing to do with diet and therefore prescribe the costly drugs Restasis and Xiidra (each cost $500-$550 per month), Dr. Polack rarely has to resort to use of these awful agents. Here Dr. Polack speaks about his phenomenal experience. More a...

Keratoconus and other ectasias are, fundamentally, disorders of refractive error. Since management options span the entire spectrum of anterior segment surgery, these conditions do not respect traditional disciplinary lines between the refractive surgeon, the cataract surgeon, and the corneal transplant surgeon. Corneal crosslinking (CXL), phakic IOL implantation, lens extraction with toric lens implantation, small aperture sulcus implants, intracorneal implants, photorefractive keratectomy (PRK), transepithelial photorefractive keratectomy (PTK), deep or penetrating keratoplasty, and combinations of the above are all empl...

Abstract Here, we present, to the best of our knowledge, the first case of Werner syndrome with corneal blindness due to bilateral primary bullous keratopathy. Werner syndrome is a rare autosomal recessive disorder characterized by features of premature aging, insulin-dependent diabetes mellitus, osteoporosis, atherosclerosis, hypergonadotrophic hypogonadism, hypertriglyceridemia, scleroderma-like skin changes, and sarcomas. Among ocular manifestations, cataracts, cystoid macular edema, and retinal detachment have been reported. Because these patients show features of premature aging, they have decreased corneal e...

We report a case of cataract-combined penetrating keratoplasty that required rekeratoplasty for refractive status because of the inadvertent use of a cornea from a donor who had undergone LASIK surgery. The case presents the use of perioperative visualization, anterior segment optic coherence tomography, and histopathologic confirmation. A 63-year-old female patient with leukoma and cataract in the left eye underwent combined cataract surgery and penetrating keratoplasty. During surgery, a jelly-like layer extending a few millimeters in diameter was observed around the lenticule. In addition, the graft was noticed to separ...

Conclusions: Rasch analysis showed that Catquest-9SF is a valid instrument for measuring visual disability in patients who have undergone corneal transplantation primarily to improve vision.

DISCUSSION: The underlying disease, together with the surgical history, was responsible for the complication presented. The correct anamnesis prior to cataract surgery, a refined technique, and a close post-operative follow-up can avoid such a serious complication. Immunomodulatory treatments are essential in this type of patient. PMID: 28743413 [PubMed - as supplied by publisher]

Conclusion In the absence of human donor corneas, a porcine keratoxenoimplant can be used as temporary therapeutic keratoplasty in case of emergency stop the inflammation process and to save the eye. In cases of keratoxenoimplant, a poor visual outcome is expected. PMID: 28683478 [PubMed - as supplied by publisher]
