Therapeutic ocular surface medium for persistent corneal epithelial defect

Corneal ulcers and persistent epithelial defects (PEDs) are caused by a variety of different insults to the cornea, which includes limbal epithelial stem cell failure. PED may be resistant to healing with standard therapy such as frequent ointments and /...

Usefulness of gonioscopy to investigate cause of corneal oedema after cataract surgery

A 72-year-old man with ocular hypertension presented three months after routine right phacoemulsification and toric intraocular lens (IOL) implantation with a two-week history of an irritated right eye and a sudden deterioration in right vision. His preoperative spherical equivalence was...

Incidence of high IOP following corneal collagen cross-linking

This retrospective cohort study examined 405 patients (405 index eyes and 218 untreated fellow eyes) who underwent cross-linking over a 12-year follow-up duration at Duke Eye Center. Preoperative and postoperative intraocular pressure (IOP) measurements were collected at ~1 month, 3...

Impact on the corneal and anterior chamber characteristics after femtosecond laser cataract surgery

Femtosecond laser cataract surgery (FLACS) is being increasingly used in the preparation for cataract surgery. Benefits of circular capsulorrhexis and reduced phacoemulsification energy have been shown in the literature. This study was designed to assess the anterior chamber characteristics and...

Can closing the eyelid during riboflavin induction phase of crosslinking increase corneal thickness?

Corneal crosslinking (CXL) with riboflavin and UVA irradiation is the standard treatment for preventing progression of keratoconus. Thinning of the cornea during the riboflavin loading phase was reported in previous studies which used riboflavin with dextran. A minimum stromal thickness...

Corneal transplantation in the United Kingdom: are we blind to the challenges that still exist after the Organ Donation Bill?

Corneal transplantation (CT) is a significant treatment option for a huge number of patients in the United Kingdom (UK) [1]. For an individual, CT results in a substantial improvement in quality of life. Penetrating keratoplasty with full thickness grafting has...

Intraocular lens choice in patients who have undergone previous corneal refractive surgery

Patients who underwent vision correction in their 20s to 40s are now entering their 50s and 60s, the typical starting age for cataract development [1]. Consequently, ophthalmologists are increasingly encountering patients whose corneal profiles have been surgically altered, requiring advanced...

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...

Systematic review investigating the time taken for corneal stabilisation following contact lens cessation

A systematic literature review of 15 studies (13 prospective, 1 retrospective and 1 case observational case series) to assess corneal stabilisation post-contact lens (CL) cessation by using corneal imaging techniques. The included studies reported stabilisation of corneal parameters as follows;...

Effect of long-term scleral contact lenses on corneal topography, tear film and impression cytology in keratoconus

This study of 16 keratoconus patients aimed to investigate the impact of long-term scleral contact lens (ScCL) wear on corneal curvature, corneal thickness, tear film function and ocular surface in patients with keratoconus. Corneal topography, tear osmolarity test, Schirmer 1...

Histopathology-guided management of ocular surface squamous neoplasia (OSSN) with corneal stromal or scleral invasion using ruthenium-106 plaque brachytherapy

This is a retrospective interventional consecutive case series of 42 eyes of 42 patients with OSSN with histopathologically proven corneal stromal and / or scleral invasion following excision biopsy. The mean tumour basal diameter was 9.3mm and thickness of 3.1mm...

Nurse-led Rapid Corneal Collagen Cross-linking / UKISOP Society Education Day

Nurse-led Rapid Corneal Collagen Cross-linking By Dan Gore Over the last decade, clinical trial data has accumulated for new interventions in keratoconus that promise to arrest disease progression, significantly reduce transplantation rates and save many patients from long-term reliance on...
