Fifteen patients were recruited having medial rectus resection surgery. Resection sections...

Influence of FLEx and SMILE on corneal nerve density and ocular surface

This was a prospective study designed to compare the influence of femtosecond lenticule extraction (FLEx) and small incision lenticule extraction (SMILE) on the corneal nerve density and ocular surface for myopic correction. Thirty patients underwent bilateral lenticule extraction. One eye...

Development of a modern surgical simulation suite to promote safer ophthalmic surgical training

For trainees, having access to surgical simulation equipment is more important than ever. The authors describe the creation of a bespoke teaching and training suite in Glasgow to help trainees develop their skills and promote surgical excellence. Simulation has become...

Microdroplet and splatter contamination during phacoemulsification in COVID-19 era

Half a millilitre of fluorescein was incorporated into 400ml of balanced salt solution to identify microdroplet and splatter from phacoemulsification to simulate possible COVID-19 contamination. Five porcine eyes were mounted to an ophthalmic mannequin head and two surgeons (height 189cm,...

Dead bag syndrome: a new and rare cause of late IOL dislocation

The dead bag syndrome has recently been described as a cause of late spontaneous intraocular lens (IOL) subluxation and / or dislocation. The capsular bag remains clear years after surgery and then becomes diaphanous and floppy. The authors explanted seven...

OCT in microtropia

The aim of this study was to assess whether OCT could be useful in detecting and documenting fixation in children with microtropia. The study used spectral domain OCT (Cirrus) in 15 patients (10 female, five male) and 10 control eyes....

History A 35-year-old male presents with bilateral corneal opacities. Examination shows a honeycomb-type dystrophy. A penetrating keratoplasty is performed and the specimen sent for ophthalmic histopathological assessment. Figure 1 is the haemotoxylin & eosin (H&E). Figure 2 is a Masson...

Corneal lenticule allotransplant

This animal study looked at corneal lenticule allograft transplantation in rabbits. Seven rabbits underwent small incision lenticule extraction (SMILE) procedures, where their stromal lenticules were extracted and transplanted fresh into pre-prepared corneal stromal pockets of seven recipient eyes. Animals were...
