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...

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...

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...

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...

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...

Measurement considerations in OCT results with suspected glaucoma

The purpose of this study was to determine retinal nerve fibre (RNFL) thickness parameters and assess the relationship between the cup-to-disc (CD) ratio and RNFL measurements of paediatric patients who had optic nerve appearance suspicious for glaucoma based on enlarged...

Surgery technique for subluxation in Marfan syndrome

The authors evaluated the efficacy and safety of bimanual capsulorrhexis combined with sutureless scleral-fixated IOL implant in children with Marfan syndrome. Seven children (14 eyes) with subluxated lenses underwent bilateral surgery; four female, three male with mean age of 7.1...

PlusoptiX and SPOT screening

The goal of this study was to determine whether an instrument that uses referral criteria having a high specificity (plusoptiX S08) would fail to refer children who have significant amblyopia and who would have been detected by an instrument using...

Myopia-protective against diabetic retinopathy

This meta-analysis evaluates the current evidence of the relationship between myopia and diabetic retinopathy (DR) risk. A systematic search was performed up to April 2015. Three models were used to assess the association between myopia and risk of DR: axial...

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...
