Cataract and Refractive
This study reports the outcome of topography-guided photorefractive keratectomy (TG-PRK) in the treatment of patients with corneal scarring. A retrospective case series including six eyes of six patients with corneal scarring and irregular astigmatism who underwent topography guided PRK. The...
Q&A: Mr Goel and Mr Loomba on alcohol delamination and phototherapeutic keratectomy (PTK) for the treatment of recurrent corneal erosion syndrome
Recurrent corneal erosion syndrome is a common, recurrent condition caused by abnormal epithelial adhesion to the underlying basal lamina. Spontaneous breakdown of the corneal epithelium can lead to the sudden onset of ocular pain, blurred vision, tearing and photophobia, typically...Combined PRK and CXL in keratoconus

Cataract and Refractive
This study aimed to investigate the results after photorefractive keratectomy (PRK) followed immediately by standard 30-minute corneal cross-linking (CXL) for keratoconus. This retrospective study included 26 eyes of 16 patients with keratoconus. Uncorrected distance visual acuity (UDVA), corrected distance visual...

Cataract and Refractive
This multicentre, retrospective, interventional case series assesses the outcomes of laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) in 113 patients taking isotretinoin between January 2003 and September 2017. Isotretinoin is contraindicated for LASIK and PRK and patients are...

This study examined changes in tear break up time (TBUT), Schirmer test, tear osmolarity and dry eye questionnaire (OSDI) score from prior to photorefractive keratoplasty (PRK), to two months and four months postoperatively. Fifty eyes of 25 patients were examined....

Stromal keratocytes are responsible for wound healing in the cornea following damage. Keratocytes at the site of injury become activated and differentiate to myofibroblasts which secrete extracellular matrix (ECM) to close the wound, a response mediated by transforming growth factor...

A major disadvantage of excimer laser photorefractive keratectomy (PRK) is pain and discomfort after the surgery, which is thought to be due to damage to corneal sensory nerve fibres or local release of inflammatory substances. Pain only resolves once corneal...
LASEK vs. epi-LASIK for myopia: meta-analysis
Previous studies have produced inconsistent conclusions on the relative benefits between LASEK vs. Epi-LASIK. LASEK uses 20% alcohol to separate an epithelial flap from the Bowman membrane. After ablation, the epithelial flap is repositioned onto the cornea. Epi-LASIK creates the...Corneal crosslinking in pellucid marginal degeneration

Cornea / External Eye Disease
Fourteen studies were included in this first review examining the use of corneal-crosslinking (CXL) to treat pellucid marginal degeneration (PMD). PMD is a bilateral, non-inflammatory corneal thinning disorder characterised by inferior peripheral corneal thinning 1-3mm from the limbus in the...

Cataract and Refractive
This study group compared contrast sensitivity among participants undergoing wavefront-guided or wavefront-optimised photorefractive keratectomy (PRK) or laser-assisted in situ keratomileusis (LASIK) for the treatment of myopia or myopic astigmatism 12 months after surgery. This was a prospective, randomised clinical trial,...
