Surgical outcome reporting for exotropic DRS

The authors report the surgical outcomes of patients with exotropic Duane’s retraction syndrome (DRS) in a retrospective study of 73 patients; 67 unilateral cases. Patients had a mean age at surgery of 14.11 years (range 2-33). The left eye was...

Association between COVID-19 restrictions and accelerated myopia progression

A retrospective case review aimed to evaluate the association between home confinement and progression of myopia in Argentina during 2020. Data was collected using an online survey of ophthalmologists throughout Argentina. The inclusion criteria included being five to 18-years-old, found...

Topography based keratoconus progression after corneal collagen cross-linking

Case 1 describes a 35-year-old man with progressive keratoconus (PK). His best corrected visual acuity (BCVA) was right 20/80 (-5.25/-7.75 x 85) and left 20/20 (+4.75/-5.00 x 90). His Ks were right 36.32/48.02 D and 41.15/46.41 D. Right central cornea...

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...

Principles of contact lens fitting in keratoconus

Keratoconus is an ectatic condition of the cornea characterised by progressive conical distortion with irregular astigmatism, myopia and apical protrusion. Most cases progress slowly resulting in varying degrees of myopic astigmatism. Management of keratoconus includes spectacles, soft contact lenses, a...

IR recession and prevention of lower lid retraction

The authors report the efficacy in preventing lower eyelid retraction and long-term results of a new technique of inferior rectus recession for vertical strabismus. The results for 35 patients were compared with 22 patients having conventional inferior rectus recession. Inferior...

Blame the lens – not its position – in refractive surprise

Aetiology of postoperative refractive surprise Weber coined the term “wrong eye, wrong intraocular lens, wrong patient” in 2008 as an aide memoir of major factors believed to underlie refractive surprise – defined as a significant unintended difference between dioptric refraction...

Surgical complications of ReLEx

Femtosecond laser refractive lenticule extraction (ReLEx) is a novel procedure for treatment of myopia and myopic astigmatism, which eliminates the use of microkeratome and excimer laser. Currently there are two techniques: FLEx – femtosecond lenticule extraction (similar to conventional LASIK)...

Advances in the understanding, diagnostic and treatment of keratoconus

*Joint first authors Keratoconus is a bilateral and asymmetric eye condition in which the cornea’s structure is affected and thinned, causing a cone-shaped bulge to develop. This results in progressive loss of vision and impairs the ability of the eye...

BT vs primary surgery for infantile esotropia

In this study, the success rate of treatment for infantile esotropia (IET) patients who had surgery because of under correction after botulinum toxin (BT) is compared to those having primary surgery. The study included 52 patients (27 male) with mean...

Retreatment of myopic LASIK with femtosecond and custom ablation

The purpose of this study was to identify the risk factors for retreatment post laser in situ keratomileusis (LASIK). A retrospective chart review was carried out for a four-year period and all patients who had undergone LASIK at the Boston...

Preparing to sit the FRCOphth Part 1 as a new FY1: A modern financial, educational and AI-enhanced study guide

One week into my first year as a doctor, buried under a mountain of ward jobs, night shifts and the sheer vertical learning curve of FY1, I decided to challenge myself further: I booked the FRCOphth Part 1 exam. The...
