Accuracy of intraocular lens power calculations in paediatric eyes

A study comparing the accuracy of the SRK II, SRK/T, Hoffer Q, Holladay 1, T2 and Super formula in predictive refractive outcomes in children undergoing primary IOL insertion into the capsular bag following cataract surgery. A total of 377 eyes...

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...

Clinical evaluation of a multifocal aspheric diffractive intraocular lens

This is a multi-centre prospective study involving five different centres in Europe including 52 patients with cataract. The average age was 68.5±10.5 years, 35 females were bilateral implanted with aspheric diffractive multifocal lens implantation of the Tecnis 1-Piece multifocal intraocular...

A comparative evaluation of a new diffractive trifocal and EDOF IOLs

This study aimed to compare the outcomes of two diffractive trifocal intraocular lenses and one extended depth of focus (EDOF) intraocular lens (IOLs). This was a six month, single centred, prospective, randomised, comparative study in which patients who underwent routine...

Pentacam vs. IOL Master keratometry measurement in IOL power calculations

The IOL Master measures only the anterior corneal curvature and estimates the total corneal power by assuming a fixed relationship between the anterior and posterior corneal surface. The Pentacam measures both the anterior and posterior corneal surface and therefore calculates...

Intermittent exotropia

Four cases of intermittent exotropia are discussed. Case 1 was a nine-month-old with cycloplegic refraction of +1.0DS and a 30PD intermittent exotropia at near and distance. Discussions considered observation, part-time occlusion, refractive correction and later possibility of surgery. Case 2...

The Eye in History

Amongst the numerous texts that are available, one occasionally encounters a history of ophthalmology. There is such rapid development of technology in recent years and one can get drawn into the minutiae of a particular subject, losing track of the...

LASEK with mitomycin C to correct myopia in thin corneas

This study evaluated the long-term outcomes of laser-assisted subepithelial keratomileusis (LASEK) with intraoperative use of mitomycin C (MMC) performed on thin corneas for the correction of myopia. MMC modulates the corneal wound healing response in surface healing, thus reducing the...

Newer generation IOL platforms designed for high-quality visual performance after cataract surgery

Expanding intraocular lens (IOL) capabilities provide broadening options, ranging from next-generation monofocal IOLs for basic cataract surgery, to specialised premium IOLs for lens-based presbyopia correction and astigmatism correction at the time of cataract surgery. Rod McNeil considers several newer alternative...

A case presentation of morning glory disc anomaly and peripapillary staphyloma

The purpose of this paper is to present a case of an 18-month-old girl initially presenting with strabismus. Fixation of the affected eye was intermittent with a relative afferent pupillary defect. A fundus photography of the affected left eye showed...

Risks to visual function from blepharokeratoconjunctivitis

This study evaluated the prevalence of blepharokeratoconjunctivitis (BKC) and prevalence of amblyopic risk factors with comparison of these rates to rates in the general US paediatric population. The authors evaluated the rate of patient reported symptoms in patients with and...

Optegra Eye Health Care & ZEISS Symposium - Hands-on with latest innovations in ophthalmology

This interactive symposium, presented by Optegra Eye Care and ZEISS, will explore the latest advancements in surgical techniques, diagnostic tools, and patient care. We are proud to announce a special emphasis on practical learning through hands-on workshops
