Is laser refractive surgery safe for patients taking isotretinoin?

This multicentre, retrospective, interventional case series assesses the outcomes of laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) in 113 patients taking isotretinoin between January 2003 and September 2017. Isotretinoin is contraindicated for LASIK and PRK and patients are...

Preterm birth and refractive error in an Indian infant population

This study was undertaken to identify and compare the changes in refractive outcome in infants with and without retinopathy of prematurity (ROP), to inform incidence of refractive error. This was a prospective study of 300 consecutive premature infants with birth...

New Clinical Specialist for the North and National Refractive Specialist

Surgitrac is pleased to announce the appointment of Jessica Seers as Clinical Specialist for the North and National Refractive Specialist for lenses. With a strong clinical background and a passion for ophthalmology, Jessica steps into a dual role that supports...

Effect of refractive corneal surgery on IOP and glaucoma progression

Accuracy of intraocular pressure (IOP) measurement depends on the biomechanical properties of the cornea, including its thickness central corneal thickness (CCT) and keratometry (K). Fifty-six eyes of 56 patients with primary open angle glaucoma (POAG) who had a history of...

Corneal biomechanics and refractive outcomes after cataract surgery

The authors aimed to study a range of corneal properties and correlate them with refractive outcomes after phacoemulsification. Outcomes were reviewed in a fairly small group of 40 patients (including only right eyes) operated by two surgeons using clear corneal...

Refractive changes over time for fully accom esotropia

The purpose of this study was to determine refractive error changes across time and to define factors contributing to decompensation in patients with fully accomodative esotropia (FAET). This was a retrospective study of 223 patients with a mean age at...

Long-term improvement of stereopsis in intermittent refractive esotropia

This was a retrospective study to review the records of patients with refractive accommodative esotropia (RAET) to determine long-term stereoacuity (SA) improvement in those that showed initial poor or no stereopsis. The study included 79 patients; 54% male and mean...

Early refractive correction promotes esotropia control

This study sought to determine the incidence and characteristics of esotropia in a Northern Ireland population of children <7 years old in a one-year period. The authors report a 2013 cohort in which the area catchment had 29,365 children under...

Preventing refractive surprises by real time biometry during cataract surgery

A few months ago a retired lady presented for second eye cataract surgery. I noted on the pre-op ward round that the outcome of her first eye’s surgery looked like a refractive surprise as her spherical equivalent in that eye...

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...

Refractive surprise after cataract surgery caused by posterior capsular striae

Cataract removal with intraocular lens (IOL) implantation is one of the most frequently performed surgeries in current clinical practice [1,2]. New microsurgical techniques and refined IOL power calculations allow excellent refractive outcomes. Refractive surprise following cataract surgery is uncommon [1-3]...

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...
