Atypical Corneal Phenotype in Patients With Trachoma and Secondary Amyloidosis
Conclusions:
We describe a distinct form of TK unlike the usual presentation of dense, leucomatous, vascularized corneal scarring in trachoma. We believe that amyloid deposits in DM and the corneal endothelium have not previously been reported in patients with trachoma. (Source: Cornea)

Traumatic Flap Complications After Femtosecond LASIK
Purpose:
The purpose of this article was to evaluate the prognosis of traumatic flap dislocation or avulsion in a large series of laser-assisted in situ keratomileusis (LASIK) cases.
Methods:
Retrospective, consecutive, noncomparative case series analyzes the visual and anatomical results after flap dislocation or avulsion, caused by trauma occurred at least 1 month after LASIK.
Results:
A total of 37,315 eyes of 19,602 patients were reviewed. A traumatic flap complication was observed in 9 eyes of 9 patients, with a maximum interval of 37 months after surgery. Flap dislocation with central full-thickness...

Assessment of Corneal Densitometry in Big-Bubble Dissection Versus Manual Dissection Deep Anterior Lamellar Keratoplasty
Purpose:
The aim of this study was to assess corneal densitometry and visual outcomes after big-bubble deep anterior lamellar keratoplasty (BB-DALK) and manual dissection deep anterior lamellar keratoplasty in patients with keratoconus.
Methods:
This retrospective comparative observational study included 40 keratoconic patients who underwent DALK surgery: 22 eyes had BB-DALK (group I) and 18 eyes had failed BB technique and DALK was completed by manual dissection (group II). Best -corrected visual acuity (BCVA), corneal topographic parameters, residual stromal tissue thickness, and endothelial cell count were re...

Long-term Outcomes of Cataract Surgery in Patients With Chronic Ocular Graft-Versus-Host Disease
Purpose:
The aim of this study was to evaluate the outcomes of cataract surgery in patients with chronic ocular graft-versus-host disease (GVHD).
Methods:
A retrospective review was performed on 77 eyes of 42 patients with chronic ocular GVHD that underwent cataract surgery between January 2014 and February 2020 in a tertiary institution.
Results:
Posterior subcapsular cataract was seen in 53 (68.8%) of 77 eyes, with a mean preoperative corrected distance visual acuity (CDVA) of 0.61 ± 0.49 logarithm of the minimum angle of resolution (logMAR). Postoperatively, with a mean follow-up of 21 months, CDVA im...

Conjunctival Autofluorescence and Cytological Changes in Pterygium
Purpose:
The purpose of this study was to evaluate the presence and pattern of autofluorescence and its related cytological changes in pterygium.
Methods:
Eighty-six patients with unilateral pterygium and 76 controls were recruited. We graded pterygium, looked for autofluorescence, performed cytology of the nasal conjunctiva, repeated evaluation after 6 months, compared findings with controls, and assessed the progression of pterygium from photographs with the help of ImageJ software.
Results:
Autofluorescence was present in 51% of cases with pterygium. Autofluorescence at the leading edge (65.9%) was the...

Impact of Scleral Lens on Corneal Curvature and Pachymetry in Keratoconic Eyes
Conclusions:
Minimal transient alteration in the anterior corneal curvature and corneal thickness was observed after 6 hours of scleral lens wear. These temporary changes regressed to baseline after overnight discontinuation of the lens. (Source: Cornea)

Outcomes of Microbial Keratitis Cases Resistant to Antimicrobials in Sydney, Australia
Purpose:
The purpose of this study was to describe demographics, predisposing factors, clinical features, treatment, and outcomes of microbial keratitis cases resistant to antimicrobials.
Methods:
A retrospective case series was conducted. All patients with microbial keratitis resistant to antimicrobials who underwent a corneal scrape and culture from 2012 to December 2016 at the Sydney Eye Hospital were included. Cases were identified from pathology and hospital coding data. Coagulase-negative staphylococci (CoNS), Staphylococcus aureus (S. aureus), and Corynebacterium spp. resistant to cefalotin, chloramphenic...

Glaucoma Evaluation and Management in Eyes With Boston Type 1 and Aurolab Keratoprostheses in an Indian Cohort
Purpose:
The purpose of this study was to evaluate glaucoma and its management in eyes with Boston type 1 keratoprosthesis (Boston-Kpro) and Aurolab keratoprosthesis (Auro-Kpro) in an Indian cohort.
Methods:
This retrospective comparative case series included 175 eyes of 175 patients who underwent type 1 keratoprosthesis from 2009 until 2017; type 1 Boston-Kpro was performed in 107 eyes (107 patients) and Auro-Kpro in 68 eyes (68 patients). The eyes with (Source: Cornea)

Clinical Factors for Determining the Severity of Lid Wiper Epitheliopathy in Dry Eye
This study involved 76 eyes of 76 female patients with dry eye (mean age: 57.2 yrs). In all eyes, tear meniscus radius, spread grade (SG) of the tear film lipid layer (ie, SG 1–5, with 1 being the best), fluorescein breakup time (FBUT), fluorescein breakup pattern, corneal and bulbar conjunctival epithelial damage (CED: 15 points maximum; CjED: 6 points maximum, respectively), upper eyelid LWE grade (3 points maximum), and Schirmer 1 test were evaluated. Blink rate, palpebral aperture height, upper eyelid opening/closing-phase amplitude, upper eyelid opening/closing-phase duration, and upper eyelid opening/closing-phase ...

Deep Anterior Lamellar Keratoplasty: Current Status and Future Directions
Abstract:
Deep anterior lamellar keratoplasty (DALK) involves selective replacement of diseased corneal stroma while preserving normal healthy endothelium. Despite several well-recognized advantages, the uptake of DALK has remained sluggish with an adoption rate that has plateaued over the past decade. Misconceptions such as the rarity of complications of penetrating keratoplasty, lack of standardization of the DALK technique, and limited substantial benefit in visual and refractive outcomes are frequently cited as arguments against performing DALK. This brief review discusses the recent findings that refute these perc...
