Topography-guided photorefractive keratectomy in the treatment of corneal scarring

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...

Combined PRK and CXL in keratoconus

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...

Dry eyes after photorefractive keratoplasty

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....

Is laser refractive surgery safe for patients taking isotretinoin?

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...

Stromal cell alignment in damaged cornea

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...

Effect of topical diclofenac on postoperative PRK pain: RCT

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

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...

Contrast sensitivity after laser corneal surgery

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,...

An arm and a leg

“It cost me an arm and a leg.” – Mr B told me. An arm and a leg to be seen by the famous Russian eye surgeon who said that everybody can be spectacle-free. He took Mr B’s money (roughly...

Bausch + Lomb releases new software on TECHNOLAS® TENEO™ 317 Model 2 providing surgeons with improved usability

The latest generation excimer laser from Bausch + Lomb, indicated for refractive surgery and presbyopia treatment, will now include additional functionalities with the 1.30 software upgrade.

Corneal keloid: Report of natural history and Outcome of Surgical Management in Two Cases

Corneal keloids are rare and typically reported following trauma (including post-surgical) and has been reported without any trauma or previous surgery. A corneal keloid differs from a hypertrophied scar in that it occurs months/years after the injury, enlarges over time...
