Outcomes of early versus late surgery for infantile esotropia

The authors aimed to provide a better understanding of the clinical spectrum of infantile esotropia by comparing motor and sensory results in the long-term follow-up of patients who underwent surgery. This was a retrospective review over a 17-year period. There...

Congenital ptosis and astigmatism

This is a review of the effect of congenital ptosis surgery on refractive error. Seventy-one eyes of 56 patients were reviewed. The unoperated eye in unilateral cases was used as the control group. The mean age at surgery was 5.1...

Prediction errors of formulas in optical biometers

This study was conducted retrospectively in a private practice setting. Nine formulas were compared for prediction error (postoperative spherical equivalent (SE) minus, predicted SE calculated by each formula), using two optical biometers (Lenstar – optical low coherence reflectometry (OLCR) and...

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...

Strabismus in thyroid eye disease

Pathogenesis Thyroid eye disease (TED) is an auto-immune condition, in the initial phase there is lymphocytic infiltration and oedema of the extraocular muscles with deposition of glycosaminoglycans and hyaluronic acid and adipogenesis, which can lead to an increase in the...

Posterior capsular rupture risk factors as reported in the European registry

In this cross-sectional review of the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO) including 2,853,376 patients and 31,749 cases with posterior capsular rupture (PCR), the authors observed a trend of reduction in PCR rate from 1.44%...

Hughes flap for lower lid retraction

This is a retrospective case series looking at the use of Hughes flap for cicatricial lower lid retraction. Fourteen patients were identified across five different hospitals with varying aetiologies ranging from previous lid lesion excision and reconstruction to trauma. The...

The refractive index in the eye lens – implications for clinical practice and optical design

The eye may appear to be a comparatively simple organ and yet its optical system is complex and continues to be a source of investigation and research. The major optical elements are considered to be the cornea and the lens...

Late stromal rejection in DALK

This case series reported on late stromal rejections in eyes after uncomplicated deep anterior lamellar keratoplasties (DALKs). Four eyes of three patients experienced episodes of isolated stromal rejection 33 to 46 months after surgically uncomplicated DALKs and a minimum of...

Outcomes of horizontal muscle transplantation

The authors propose the technique of transplantation of the resected muscle segment to the previously recessed muscle for correction of residual / recurrent strabismus in order to restrict surgery to one eye and avoid large recession of previously recessed rectus...

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...

A simple technique for managing eyelid retraction in a patient with an exposed Boston type 2 keratoprosthesis (Kpro)

The article describes a patient with mucous membrane pemphigoid and a Boston type 2 Kpro. In the early postoperative period (one week) inferior skin retraction was noted with exposure of the Kpro and carrier cornea. The exposure was managed by...
