Implantation of diffractive trifocal intraocular lens

This study reports on 60 eyes of 120 patients who underwent routine cataract surgery followed by implantation of the trifocal IOL model Lisa tri-839MP. This is a diffractive trifocal preloaded IOL with no interruption at the haptic-optic junction, 360 degrees...

Management of high AC/A esotropia

The purpose of this study was to determine the long-term effect of treating high accommodative convergence to accommodation (AC/A) esotropia with single vision lenses (SVL) compared with the effectiveness of using SVL on patients with basic refractive esotropia and a...

Childhood headaches

The goal of this study was to compare headache resolution in children receiving or not receiving refractive correction. The authors conducted a retrospective review of 158 patients: 78 male and 80 female aged three to twelve years (mean eight). Twenty-seven...

QuickSee Free autorefractor results in outreach settings

The Gambia screening project was launched in 2022 to provide vision screening for school-aged children. Within this screening programme, the refractive error measurements of the QuickSee Free autorefractor were compared to cycloplegic refraction in this outreach setting. Six rural schools...

BT outcomes for accommodative esotropia

The purpose of this study was to study the effect of Botulinum Toxin (BT) in refractive and non-refractive accommodative esotropia unresponsive to glasses and poor compliance with glasses. This was a retrospective study of 114 patients who had BT for...

Refraction planning in cataract: avoid creating an unhappy patient

“It is much more important to know what sort of a patient has a disease than what sort of a disease a patient has.” William Osler The focus of this paper is the prevention of an unhappy patient following cataract...

Changes in axial length and refraction in young Chinese school children

The authors aimed to assess refractive error and axial length in children aged seven to eight years (grades 1-2) starting education in South China. The study reviewed 301 students and obtained data for analysis from 291 (50.2% female). Average axial...

Spot screener versus Grand Seiko measurements

The authors aimed to determine repeatability and reproducibility of refractive values and pupil size measured using the Spot Vision Screener and to compare its measurement values with the Grand Seiko autorefractor. This was a cross-sectional study of 22 healthy adults;...

Biomechanical stabilisation of ocular measurements post cataract surgery

This prospective study looks into the time duration of biomechanical stabilisation post uneventful cataract surgery in a case series of 62 consecutive eyes in patients with no ocular or systemic comorbidity. The patients were followed-up at fixed intervals of one...

Photoscreener use in pseudophakia

The purpose of this study was to compare refractive data obtained by the Plusoptix and SPOT to data obtained during masked paediatric ophthalmic examinations with retinoscopy in 44 pseudophakic eyes of 44 children. The average age at measurement was 7.4...

Open-field autorefraction screening

This study aimed to determine the efficacy of the Shin-Nippon NVision-K5001 autorefractometer using the open-field refractometry principle in the elimination of accommodation in children. One hundred and fourteen patients aged three to six years were recruited. After excluding ocular pathology...

Change in hyperopia with strabismus

This study aimed to evaluate hyperopic evolution patterns in children with early diagnosis (before three years) and treatment. This was a retrospective study of 78 eyes of 39 children. Forty-nine percent were males and mean follow-up was 130 months (72-193)....
