Descemetorhexis Without Graft Placement for the Treatment of Fuchs Endothelial Dystrophy: Preliminary Results and Review of the Literature
Conclusions: In partial concordance with previous studies, preliminary outcomes of a central descemetorhexis in FECD performed without endothelial graft placement seemed rather unpredictable. Baring of central stroma may trigger a variable wound-healing response with subsequent posterior stromal scarring and topographical irregularity.
Abstract OBJECTIVE: To evaluate the changes of visual acuity, contrast sensitivity, astigmatism, and higher order aberrations after blepharoplasty in patients with dermatochalasis. METHODS: Two hundred six eyelids of 103 patients with dermatochalasis were prospectively studied. Visual acuity, contrast sensitivity, corneal topography, astigmatism degree, and higher order aberrations were examined and recorded before and at 1 month after upper eyelid blepharoplasty. Change in contrast sensitivity and astigmatism values were determined according to margin reflex distance of patients, which were classified into t...
Conclusions: DWEK induces an increased central posterior float localized to the site of Descemet membrane stripping, confirming the need for centralized stripping. Irregular astigmatism can occur after DWEK but is typically minimal and occurs more commonly in the setting of preoperative irregular astigmatism. DWEK induces about a 0.5 D hyperopic shift, which should be considered when determining intraocular lens power with simultaneous surgery.
CONCLUSION: Analysis of data detected a misdiagnosis of ectasia in 20 patients (26 eyes), a finding of 2.0% (20 of 1000) of referred cases that did not satisfy the diagnostic criteria of corneal ectasia. These conditions are considered a contraindication to corneal crosslinking and there is usually no benefit to topography-guided PRK or intrastromal corneal rings. It is important that clinicians recognize the clinical findings of these conditions and differentiate from true keratoconus, pellucid marginal degeneration, or ectasia after laser vision correction.

CONCLUSIONS Alport syndrome patients without classical ophthalmological findings have smaller crystalline lens diameter and lower lens power. These signs may support the diagnosis of Alport syndrome. Ophthalmologists should not only seek for the known classic signs, but also the parameters of the crystalline lens, especially if genetic testing is not available.

Conclusion: The pressure of upper eyelid in patients with ptosis appeared to have resulted in steepening of the superior cornea along this axis. The surgical correction of ptosis induces flattening of superior cornea as shown by significant decrease in apical keratometry front value postoperatively and restores corneal topography to a more regular state.
Rationale: The etiology of anterior corneal opacities and the effect of debridement cannot be determined by biomicroscopy. Optical coherence tomography (OCT) helps identify the character and depth of these lesions. Patient concerns: A 45-year-old female complained of progressive blurred vision for a long time. Slit lamp biomicroscopy showed irregular, faint scar-like opacity of anterior cornea in her both eyes. Pentacam Scheimpflug camera tomography showed irregular astigmatism of anterior corneal surface. Anterior segment spectral-domain OCT revealed thickened, hyper-reflective linings, and scattered lesions, mainly ...
CONCLUSION: Axial length and risk factors of amblyopia such as anisometropia, hyperopia, and strabismus were not associated with UCNLDO. UCNLDO is likely an isolated defect.
CONCLUSION: Superficial keratectomy is a simple, safe procedure that can be performed for a variety of conditions to improve visual acuity, reduce corneal astigmatism, and alleviate symptoms secondary to ocular surface pathology. PMID: 30502977 [PubMed - in process]
Conclusion: Not all patients of intraoperative DM perforation (including macro perforation) needs to be converted to penetrating keratoplasty. DALK can be successfully done if the perforation is identified early and managed adequately. This is the only known study which has shown a large series of successful DALK even with macro perforations.
Conclusions: Although CEC density of patients with PCV in this study was found to be stable over a long-term follow-up period, strict attention should be given to the possibility of amblyopia in eyes with PCV.
