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...

Myopathic ptosis and lower lid retraction surgery

This is a description of a surgical technique which simultaneously addresses both the upper lid ptosis and lower lid retraction in patients with moderate to severe myopathic ptosis. The procedure was performed on 16 eyes of nine patients and involved...

Development of testing protocols for high and low contrast visual acuity

Dysfunction of the afferent visual system, characterised by impairments in high-contrast visual acuity (HCVA) and low-contrast visual acuity (LCVA) have been demonstrated in some neurological conditions such as multiple sclerosis and Parkinson’s disease. HCVA and LCVA are also potential quantitative...

Outcome of surgery for infantile exotropia after long-term follow-up of 4 years

The purpose of this study was to report long-term motor and sensory outcomes after unilateral lateral/medial rectus recession/resection (RR) in infantile constant exotropia. This was a retrospective review from 1995–2020 of 20 children (10 female, 10 male) with minimum 4-year...

Capsular tension rings to reduce refractive shift

The study group aimed to determine whether the use of a capsular tension ring (CTR) can increase refractive stability in patients with implantation of two different trifocal intraocular lenses. This was a prospective, consecutive series of eyes which underwent refractive...

Changes in refractive error in patients with accommodative esotropia after being weaned from hyperopic correction

This is a retrospective review of medical records of 47 patients with refractive ocular accommodative esotropia who achieved emmetropisation and orthotropia without hyperopic glasses correction and were followed up for at least three years. The objective of the study is...

What intentional eyecare looks like: Lessons from Aravind Eye Hospital

Jet-lagged, following 24 hours of travel from Boston, sweat rolled down my forehead only to return moments after I had wiped it away. Even the English signs seemed suddenly indecipherable in the humid midday heat of Pondicherry, India. I’ll never...

ESASO Course Series (Volume 3): Cataract

T­­­­­his book is designed as a course manual for cataract and refractive surgery. It starts off by discussing both the fluidics and dynamics of phacoemulsification, touching techniques and management of difficult scenarios. The ins and outs of conventional, accommodative, toric...

Unravelling ocular motility

Ocular motility can often be a slightly abstract concept during the earlier years of ophthalmology training. A large variance on what embodies normality; mythical concepts like fusion and binocular vision, examination techniques that can be fiddly, and complex neuroanatomy all...

Scheimpflug images and graft rejection

This study aimed to assess corneal changes using 360-degree Scheimpflug images and pachymetry readings to outline screening parameters, which define graft rejection. Seventeen eyes of 16 patients developed clinically manifest allograft rejection two to 42 months after surgery – those...

Patients prefer vision from lasik than from smile in a contralateral-eye trial

This prospective, randomised, single surgeon, contralateral-eye clinical trial compared the results in myopic patients undergoing wavefront-guided femtosecond laser in situ keratomileusis (LASIK) in one eye and small-incision lenticule extraction (SMILE) in the fellow eye. The patient-reported outcomes with laser in...

Biometry and IOL choice errors

In the next instalment of this series I focus on problems associated with biometry and intraocular lens (IOL) selection for cataract surgery. I have taken previous medicolegal cases I have dealt with and tried to extract some learning points and...
