Benjamin L Custer, Steven R Ballard, Robert B Carroll, Scott D Barnes, Grant A Justin
PURPOSE: To review data on malpractice claims related to refractive surgery to identify common allegations and injuries and financial outcomes. METHODS: The WestlawNext database was reviewed for all malpractice lawsuits/settlements related to refractive eye surgery. Data evaluated included patient demographics, type of operation performed, plaintiff allegation, nature of injury, and litigation outcomes. RESULTS: A total of 167 cases met the inclusion criteria, of which 108 cases (64...

Zeba A Syed, Jennifer A Tran, Ula V Jurkunas
PURPOSE: In advanced Fuchs endothelial corneal dystrophy (FECD), central endothelial changes do not correlate with disease severity. The peripheral endothelial cell count (ECC) has not been studied as a marker of FECD severity. The goal of this study was to determine the relationship between the peripheral ECC and known clinical markers of FECD in advanced cases. METHODS: Patients with FECD examined between January 1, 2013, and September 1, 2016, by 1 cornea specialist were identified...

PURPOSE: To assess the correlation between corneal biomechanical stiffness and refractive error (RE) in the pediatric population. METHODS: A total of 733 pediatric eyes were included in the study retrospectively. All eyes underwent corneal tomography (Pentacam), RE assessment, and air-puff deformation (Corvis-ST). Waveform analyses of deformation provided corneal stiffness (CS) and extraocular tissue stiffness (EOS). Eyes were subgrouped into emmetropia [manifest refraction spherical equivalent (MRSE) ∼ 0 D], hyperopia (MRSE > 0 D), myopia I (MRSE between 0 D and -3 D), myopia II (MRSE between -3 D and -6 D), and myopia III (MRSE greater than -6 D) for multivariate analyses...

PURPOSE: To describe a simple preoperative ink test as a novel adjunct to intrastromal keratopigmentation for post-laser peripheral iridotomy (LPI) dysphotopsias. METHODS: A surgical marking pen is applied to the area over a peripheral iridotomy before intrastromal keratopigmentation. The patient can then assess whether there is any improvement in their symptoms of dysphotopsias. Manual intrastromal keratopigmentation can then be performed using a crescent blade into the clear cornea at 50% depth and tunneled centrally to create a pocket ensuring that the peripheral iridotomy is fully occluded...

PURPOSE: To present the results of 15 cases in which a modified technique of Descemet membrane endothelial keratoplasty (DMEK) with vent incisions was used to assist unfolding of tight peripheral inward folds. METHODS: This is a retrospective case series of 15 consecutive eyes that underwent a modified vent incision technique for DMEK. Six oblique, small-size (1 mm) vent incisions parallel to the limbus and 3.5 mm from the center were performed after descemetorhexis...

PURPOSE: To establish an initial estimation of the MCID of the University of North Carolina Dry Eye Management Scale (UNC DEMS) and assess its association with patient perceptions of symptom change. METHODS: Thirty-three patients (33.3% men, 67.7% women, mean age 60.5 yrs) with previous DEMS scores were recruited from a UNC ophthalmology clinic in spring 2014. We used anchor-based methods, categorizing important symptom change, to compare the change in the DEMS scores across visits to patient assessments of change; linear regression coefficients estimated the MCID...

PURPOSE: Endothelial plaques are a typical characteristic in patients with fungal keratitis. However, bacterial keratitis and herpetic keratouveitis are rarely associated with fibrin formation on the retrocorneal surface. This study was conducted to examine plaques attached to the endothelium in patients with infectious keratitis using anterior segment optical coherence tomography (AS-OCT). METHODS: Seventeen patients (10 women and 7 men; mean age, 75 ± 15.5 years) suspected to have infectious keratitis with retrocorneal plaques were included...

PURPOSE: To minimize recurrence and improve graft stability after pterygium surgery, conjunctival autograft adherence is done using fibrin glue (FG) or autologous blood coagulum (ABC). But there are studies that have reported conflicting or inconclusive results. This meta-analysis was conducted to evaluate the postoperative recurrence rate and graft stability after using FG, sutures, and ABC. METHODS: MEDLINE, Cochrane databases, and ICTRP were searched and PRISMA guidelines as well as recommended meta-analysis practices were followed...

PURPOSE: The objective of this study was to determine the efficacy and safety of topical tacrolimus compounded in the Pharmacy Service for the treatment of subepithelial corneal infiltrates (SEIs) secondary to adenoviral keratoconjunctivitis. METHODS: This retrospective study included patients who had been dispensed topical tacrolimus for the treatment of SEIs during the previous year. Patients were treated with tacrolimus 0.03% eye drops twice daily or tacrolimus 0...

PURPOSE: To find out the interrelationships between 3 parameters of the keratoconic cone. METHODS: A total of 101 keratoconic eyes of 58 patients were included in this retrospective case series study. A complete eye examination was performed. Kmax (K) and pachymetry at the thinnest point (T) were obtained from the Pentacam tomographer. The vertex to thinnest pachymetry distance (D for decentration) was calculated using trigonometry. Pearson correlation coefficients between T and D, between T and K, and between D and K were calculated...

PURPOSE: To compare the effects of collagen cross-linking (CXL) and amniotic membrane transplantation (AMT) on acute corneal alkali burns. METHODS: After establishment of an alkali burn model, 32 rabbits were divided into 4 groups: control group, AMT group, CXL group, and AMT + CXL (combined) group. Clinical parameters, including epithelial wound, opacity, ulceration, and neovascularization, were evaluated on postinjury days 1, 7, 14, and 18. Histological parameters were examined in hematoxylin/eosin (H&E) and Masson trichrome-stained corneal sections...

PURPOSE: To quantify consistency of endothelial cell density (ECD) measurements among technicians in a single US eye bank operating under typical operating conditions. METHODS: In this retrospective analysis of 51 microscopy technicians using a semiautomated counting method on 35,067 eyes from July 2007 to May 2015, technician- and date-related marginal ECD effects were calculated using linear regression models. ECD variance was correlated with the number of specular microscopy technicians...

PURPOSE: To describe the outcomes of femtosecond laser-assisted tuck-in penetrating keratoplasty as a single-step surgical procedure for visual and anatomical rehabilitation of patients with severe keratoglobus (KTG) and endothelial damage. METHODS: Two eyes of a 7-year-old patient with bilateral severe KTG and previous corneal hydrops were operated. Assisted by the femtosecond laser, both donor and recipient corneas were prepared. An 8.5-mm full-thickness donor tissue with a peripheral partial-thickness rim of 1...

PURPOSE: To evaluate the effect of topical application of a matrix regenerating agent (RGTA) in subjects with a persistent epithelial defect after bacterial keratitis treated with topical fortified antibiotics. METHODS: In this prospective case series of 14 subjects (14 eyes) with a persisting corneal ulcer after the cessation of fortified antibiotics, subjects were treated with an RGTA at a dose of 1 drop every other day. The main outcome measure was the proportion of subjects with complete corneal healing 1 month after initiation of treatment...

PURPOSE: To investigate the incidence of limbal stem cell deficiency (LSCD) in donor eyes after conjunctival limbal autograft (CLAU). METHODS: An observational retrospective review was performed on all patients who underwent CLAU alone, combined keratolimbal allograft with CLAU ("Modified Cincinnati Procedure"), or combined living-related conjunctival limbal allograft (lr-CLAL) with CLAU having ≥6 months of follow-up after surgery. The outcome measures were best-corrected visual acuity (BCVA) and ocular surface status...
