IO belly transposition surgery

The authors evaluated inferior oblique (IO) muscle belly transposition to correct mild to moderate IO overaction with small primary position hypertropia. They reviewed 10 patients aged 6-35 years (mean 18.6 years). Aetiologies were mild unilateral superior oblique (SO) palsy for...

Intraocular lens technology to deliver enhanced optical performance after cataract refractive surgery

Modern cataract surgery aims to provide patients with the best possible visual outcome with the least dependence on spectacles and minimal or no complications and to treat both cataract and refractive errors with a single procedure. Phacoemulsification is the standard...

Comparison of surgical procedures for third cranial nerve palsy with large-angled exotropia

The authors present a retrospective case review with the aim to compare two surgical procedures. Cases were operated on at a single centre, by a single surgeon, over a 14-year period. The inclusion criteria were cases with congenital or acquired...

Is lens constant optimisation for IOLMaster indispensable in order to achieve a good refractive outcome?

A study of refractive outcomes following cataract surgery was carried out with the aim of comparing the postoperative refractive outcomes against Royal College of Ophthalmologists standards and to determine the extent of association between accuracy of intraocular lens (IOL) power...

Corneal molecular and cellular biology for refractive surgeon

This is an interesting literature review that looks into the recent advances concerning the corneal molecular and cellular processes that are involved in the wound healing response after excimer laser surface ablation and LASIK surgery. It talks about the complex...

Cyclo spray vs. drops

The purpose of this study was to investigate whether cyclo spray is better tolerated than cyclo drops and to assess the adequacy of cycloplegia achieved by spray for objective refraction. Cyclo drops were given to 72 children and cyclo spray...

Anything new in the control of myopia progression?

This is a review article looking at up to date concepts and evidence in myopia control from current literature and studies. The authors identified that myopia control is best measured in absolute change in axial length as opposed to refraction...

Myectomy with or without proximal end tucking for inferior oblique overaction

This study aimed to compare the outcomes and impact of inferior oblique muscle myectomy with and without tucking the proximal end of the muscle into Tenons capsule in two surgical groups as a treatment for inferior oblique overaction. Tucking the...

Confocal microscopy and corneal graft rejection

Forty-five patients following penetrating keratoplasty (PK) were examined with the HRT III Rostock Cornea Module confocal microscope at various points after their surgery for two years. Activated keratocytes (AKs) were counted manually and their mean number evaluated. A pattern was...

Surgical treatment of high myopia

Although several excellent modalities are available for correcting high myopia, the surgical treatment of this condition remains one of the biggest challenges for refractive surgeons; this group of patients is often very dependent on contact lenses. If these patients become...

Delayed surgical treatment of orbital trapdoor fracture in paediatric patients

This is a retrospective study of 30 patients between three and 14-years-old, recruited between January 2008 to September 2016, who underwent surgery for trapdoor fractures. Two groups were evaluated: Group A- 17 patients with muscular entrapment, Group B- 13 patients...

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...
