The hardest job I had for this issue was to decide which papers to include and which papers to hang on to and save for issue 2 of 2012. At the end of December when I was choosing the content for this issue there were additional 5 papers that could have been included. The final choice came down to various factors; such as first come first served – i.e. which papers had been ready and waiting the longest; secondly which papers had been submitted the earliest; are there similar papers so that it may be beneficial to publish them alongside this paper; and also was the content something which needed to be out there quicker than other papers as it was a current hot topic? But it should be noted that o...

Around 200 abstracts are received for poster, paper, clinical spotlight, photographic and workshop presentations. The academic committee works through them and decides what should be presented and in what format. Of course some budding presenters are left disappointed but many have the task of getting their work ready for presentation at the end of May. The BCLA will now display all poster presentations electronically on the BCLA web page for members to view. Posters that are received electronically at least two weeks before the conference are also entered into the poster competition, kindly sponsored by Elsevier.

Despite advancements in a range of contact lens technologies over the past 20 years, lens-related infections remain a key consideration for practitioners and patients alike. Compliance with lens use or lens care is frequently found to be suboptimal in such cases and this issue presents a range of research studies which address this important area.

It is estimated to affect 8% of patients attending optometric practice but is poorly managed and rarely involves ophthalmic assessment. Seasonal allergic conjunctivitis (SAC) is the most common form of allergic eye disease (90%), followed by perennial allergic conjunctivitis (PAC; 5%). Both are type 1 IgE mediated hypersensitivity reactions where mast cells play an important role in pathophysiology. The signs and symptoms are similar but SAC occurs periodically whereas PAC occurs year round. Despite being a relatively mild condition, the effects on the quality of life can be profound and therefore they demand attention. Primary management...

Complete ophthalmologic examination including manifest refraction, Best spectacle visual acuity (BSCVA), slit-lamp biomicroscopy was performed and corneal topography analysis was done. According to the cone location on the topographic map, the patients were divided into central and paracentral cone groups. Trial RGP lenses were selected based on the flat Sim K readings and a ‘three-point touch’ fitting approach was used. Over contact lens refraction was performed, residual astigmatism (RA) was measured and best-corrected RGP visual acuities (...

This cost-per-wear model will assist practitioners in making an informed decision when offering advice to patients relating to the most suitable replacement modality.

The injury was repaired surgically and she had a good visual outcome, largely due to very good fortune in the site and nature of the injury. This case highlights the danger of exposing untrained handlers to snakes in the entertainment industry.

The corneal apex thickness (CAT), pupil centre thickness (recorded as CCT and corresponded to CCT of UP) and thickness at the thinnest location (CTL) were obtained and compared with each other. Corneal thickness data at 3mm and 7mm temporally, nasally, superiorly and inferiorly from the corneal apex were obtained. The mean corneal thickness values along the 2, 4, 6, 8 and 10mm diameter concentric circles, with the CTL as the centre, were also obtained. Th...

Appropriate diagnosis and understanding of the relevant pathophysiology is important to the effective treatment and an understanding of the aetiological factors responsible for erosions is critical to the development of preventative strategies and effective clinical care.

Further investigation of intraocular scatter in keratoconus is warranted to improve our current understanding of the visual deficits associated with this pathology.

For example, patient attitudes toward compliance may be improved by understanding why so many people continue to wear and benefit from the many advantages of contact lens corrections, as well as appreciating how too many patients become contact lens failures due to non-compliance. There is a strong indication for progressive monitoring of compliance but the methods used should avoid confrontation with and any offence to patients.

Delay in the onset of symptoms associated with non-compliance may allow them to assume that compliance is not important. Explanations which describe why instructions given for lens use are consistent with sustained comfortable and safe lens wear, appear to have the potential to strengthen or change patient attitudes toward being compliant. Behavior modification which reduces the prevalence of non-compliance appears likely to also help sustain better contact lens performance and reduce the prevalence of contact lens failure. These explanations could be modified for use in different practices according to the prefe...

Our data investigates the often-anecdotal evidence that thicker preparations are more effective. However, we did not find this correlation to be statistically significant suggesting further study into factors related to subjective product efficacy. These results lay foundations for the development of future products in the treatment of severe dry eye.

In its early stages it may be managed with spectacles and soft contact lenses but more commonly it is managed with rigid contact lenses. In advanced stages, when contact lenses can no longer be fit, have become intolerable, or corneal damage is severe, a penetrating keratoplasty is commonly performed. Alternative surgical techniques, such as the use of intra-stromal corneal ring...

Status of EW was either daily wear (DW), compliant EW (overnight wear of US Food & Drug Administration (US FDA) EW-approved lenses), non-compliant EW (overnight wear of DW-approved lenses). The effect of demographic and clinical characteristics on the likelihood of reporting EW was examined using logistic regression. Additionally, the effect of these same characteristics on the likelihood of non-compliant EW was assessed with logistic models.Results: Eight-hundred and eight pa...

We are seeing new products all the time and many of the challenges that patients face with contact lenses being addressed such as better vision, more comfort, and increased convenience. Soft lenses certainly have the dominant market share and have many advantages over other lens types.

More than half of the contact lens wearers surveyed were not compliant with their 2-weekly or monthly schedule. Lenses prescribed for longer replacement intervals can lead to more extreme stretching of lens life. To encourage better patient habits, eye care providers should reinforce their recommended frequency of replacement of lenses and storage cases and should reinforce care and hygiene steps at each patient visit.

The condition is most commonly found in males and usually appears between the 2nd and 5th decades of life affecting all ethnicities. The prevalence and aetiology of this disorder remain unknown. Ocular signs and symptoms of patients with PMD differ depending on the severity of the condition. Unless corneal topography is evaluated, early forms of PMD may often be undetected however, in the later stages PMD can often be misdiagnosed as keratoconus. Visual signs and symptoms include longstanding reduced visual acuity or increasing against-the-rule irregular astigmatism leading to a slow reduction in visual acuity. In rare cases, pati...

She was initially treated for a possible viral keratitis due to herpes simplex virus using 3% topical acyclovir and 0.1% dexamethasone eye drops 5 times a day. The patient did not respond to this treatment and six weeks later, corneal scrapings were positive for Acanthamoeba genotype T11.

The reasons for this are several but one suspects that there are two main issues involved. The first of these is subject matter, which may be seen as too esoteric or lacking in relevance to the day-to-day problems faced in the consulting room; and the second is the language in which research articles are generally written. For those not trained in the “scientific method”, and even for many who are, such compositions can appear dull, long winded and opaque.

High-contrast visual acuity at distance was measured with Test-Chart 2000 (100% contrast) and at near with Sloan ETDRS Near Point chart (100% contrast). Low-contrast visual acuity at distance was measured with Test-Chart 2000 (10% contrast) and contrast measurements at near with Mars letter contrast sensitivity chart.Results: Mean spherical aberration was positive for...

Data from our international contact lens prescribing survey were mined to assess recent trends in toric soft contact lens fitting. This survey was conducted by sending up to 1000 survey forms to contact lens fitters in Australia, Canada, Japan, the Netherlands, Norway, the UK and the USA each year between 2000 and 2009. Practitioners were asked to record data relating to the first 10 contact lens fits or refits performed after receiving the forms and to return them to us for analysis. The data revealed a gradual increase in the extent of toric soft lens fitting this century. Excluding Japan – which had a consistently low rate of soft toric lens fitting over the survey period – sof...

In the United Kingdom today, rigid lenses comprise 2 per cent of all new lens fits. Low rates of rigid lens fitting are also apparent in 27 other countries which have recently been surveyed. Thus, the 1998 prediction of the author that rigid lenses – also referred to as ‘rigid gas permeable’ (RGP) lenses or ‘gas permeable’ (GP) lenses – would be obsolete by the year 2010 has essentially turned out to be correct. In this obituary, the author offers 10 reasons for the demise of rigid lens fitting: initial rigid lens discomfort; intractable rigid lens-induced corneal and lid pathology; extensive soft lens advertising; su...

The introduction of silicone hydrogel materials into the market at the beginning of this century heralded the promise of successful extended wear due to the superior oxygen performance of this lens type. To assess patterns of contact lens fitting, including extended wear, over the past decade, up to 1000 survey forms were sent to contact lens fitters in Australia, Canada, Japan, the Netherlands, Norway, the UK and the USA each year between 2000 and 2009.

Prosthetic rehabilitation over the residual eyeball is the preferred treatment of choice over surgical intervention such as enucleation or evisceration. A fundamental objective of any maxillofacial rehabilitation is to enable the patient to cope up with his loss and endure the process of rehabilitation. The present article reports a simplified technique of fabricating the customized prosthesis using digital imaging technique for phthisis bulbi patients. The customized Scleral shell provides better mobility, improved appearance and less discomfort to the patient.

Data that we have gathered from annual contact lens fitting surveys conducted in Australia, Canada, Japan, The Netherlands, Norway, the UK and the USA between 2000 and 2008 indicates an overall increase in daily disposable lens fitting during this period. Daily disposable lenses are especially popular in Japan, Norway and the UK. There is a trend for these lenses to be fitted on a part-time basis. Males are over-represented in daily disposable lens fitting—a trend that is especially evident in Canada.

Certainly for the purposes of entry level into the profession the College of Optometrists in the UK, currently, examines students in the fitting of spherical lenses only but ideally prefers if the student has some knowledge of toric and presbyopic lenses, but without the requirement for fitting them in order to gain registration. For a long time these lenses were more complicated to fit and often required a practitioner with either more skill or more time. In fact we would call them ‘complex lenses’. Indeed, many patients were told they could not have contact lenses due to the level of astigmatism and patients would often declare during history and symptoms that a previous practitioner had t...

What is less known is the effect of these lenses on intraocular imaging; imaging techniques of the retina involve focussing through the entrance pupil and any visual effects caused by the anterior segment could have a consequence on the quality of the image produced.

The rationale for the study was that among dry eye sufferers who attend eye care practices for symptomatic relief, a large number present with conjunctival anomalies evidenced by tissue staining and that conjunctival recovery is essential to their successful long term management. The hypothesis tested was that the decrease in conjunctival staining with Optive is at least as good, and possibly greater, than that with Hylocomod. The cohort population was made up of 47 subjects (11 male and 26 female) aged 42±16 years with at least mild dry eye symptoms and conjunctival and/or corneal staining. The populat...

A year later, in 1987, his team deepened that effort by publishing the questions for screening dry eye patients as well . They found that 5% of patients may have been in need of further diagnostic workup for dry eye. If this issue has been researched for so many years, why is the British Contact Lens Association dedicating this special issue to clinical research aspects of dry eye in 2010? The fact remains that the clinical conundrum of determining effective, easy-to-use treatments for dry eye remains an innovating, complex area in clinical research and practice alike and remains worthy of our attention.

The instillation of any artificial tear or lubricant eye drop should decrease the tear-film osmolarity. The results found that polyethylene glycol 400, 0.25% and sodium hyaluronate (Blink® Intensive Tears) significantly improved tear osmolarity compared with carboxymethylcellulose sodium (CMC), 0.5% (Cellufresh®) and HP Guar 0.18% (Systane®) after instillation.

Pre-lens non-invasive tear break-up time (PL-NITBUT), tear prism height, bulbar hyperaemia and ocular surface temperature (OST) were measured with the lens in situ at 8, 12 and 16h of wear.Results: There was no difference between how many hours the lenses types were worn each day (F=0.90, p=0.44).

Hypo-osmotic drops have the potential to decrease contact lens osmolality which in turn may help improve ocular comfort. This has possible impact on the practitioners’ choice of the lens rewetting drop recommended and the design of future lens rewetting drops.

In phase 2, the sample was further focused, by limiting it to those adolescents who did not already wear CL.Methods: The extent to which CL satisfy aesthetic, visual, and practical needs and their effectiveness, safety, and comfort in the general population and in adolescents was rated by respondents on a 5-point Likert scale.Results: In phase 1, approximately one-third of adolescents (n=146) and parents (n=114) were CL wearers. Most adolescents (77.5% of 223) and parents (66.2% of 230) expressed...

Intra-operatively, the microkeratome oscillating pin broke during flap creation resulting in the separation of the disposable blade from the motor. This resulted in an irregular flap with missing pieces. The procedure was abandoned and the macerated partial flap repositioned as best as possible. The patient recovered a BCVA of 6/7.5. The manufacturer has since reported taking corrective measures to prevent this problem in the future. This case is a reminder that despite care and maintenance by user and manufacturer, extreme and rare hardware malfunctions can occur. Furthermore, although potentially sight threatening if managed well these complications can be followed by good recovery of vision. (Source: C...
