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.

Single-cycle soaks (6, 16 or 64h) and multi-cycle soaks (6, 16, 142 and 48h) were used to assess kinetics and saturation effects of uptake. Lens capacity for uptake of each entity was determined using a semi-saturation model. Release kinetics was assessed for these semi-saturated lenses (100-mL MPS-soaked) in 2mL of a tear mimic fluid.Results: Lenses that exhibited low uptake in a si...

The skill of these early practitioners was to design, and sometimes manufacture, contact lenses to achieve an optimal mechanical fit. The lenses were fitted minimising the pressure exercised on the ocular tissues, while allowing tear exchange, controlled movement and centration.

The introduction of silicone-hydrogel materials and daily replacement modalities has not resulted in a significant decrease in the incidence of microbial keratitis, thus suggesting that the condition is mainly dependent on patient hygiene and wearing habits. Non-compliance, which is endemic in contact lens wear, may be combated by increasing patient awareness of the potential risk factors of contact lens misuse. This is accomplished through constant, rigorous information provided by contact lens practitioners.

It is estimated to affect approximately 20% of the population. Of this subset at least 20% suffer from ocular allergy. It has a significant impact on the quality of life of the individual. Allergic diseases are those conditions in which an antibody- and/or T-cell mediated mechanisms are involved.Allergic eye diseases are characterized by IgE-mast cell mediated, as seen in allergic conjunctivitis; chronic mast cell activation and eosinophil/T-lymphocyte-mediated response, as seen in giant papillary conjunctivitis, vernal keratoconjunctivitis and atopic keratoconjunctivitis; or a T-lymphocyte-mediated response in contact ...

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 reveal an ageing demographic, with Japan being the most youthful. The majority of fits are to females, with statistically significant differences between nations, ranging from 62 per cent of fits in Norway to 68 per cent in Japan.

One patient had worse best corrected visual acuity postoperatively whereas the other did not improve beyond 6/24. We attribute this to the Descemet's folds. We believe the latter to be a complication following DLK consequent to the degree of localised corneal tissue expansion that may occur in advanced keratoconus in a pathological setting. We also discuss possible mechanisms to try to prevent such a complication.

Data gathered from annual UK contact lens fitting surveys over the past 13 years indicate that 64% of hydrogel lenses prescribed during this period were of low/medium water content (≤60% water). Whereas, in the past, practitioners would choose the water content of a hydrogel lens to meet specific clinical needs, this choice appears today to be largely governed by product availability.

Non-invasive tear break-up time (NIBUT) and tear lipid layer structure were evaluated through a slit-lamp mounted Tearscope Plus. A self-calibrating infrared thermography camera was used to record two OST values (one immediately post-blink and one immediately pre the subsequent blink). The most common lipid layer pattern observed was the amorphous pattern (48.3%).

But, in spite of this repeated advice, patients continue with their non-compliant behaviours. Is it the case of the patients not following instructions or is it a problem with the practitioners? How much influence do journal articles and conference presentations have on the prescribing and advising behaviour of practitioners? Most practitioners have heard anecdotal evidence of amazing acts of non-compliance which are frequently quoted when optometrists meet, such as the patient who swallowed her enzymatic tablets for protein removal from the contact lenses. But who is to be blamed for these errors, the optometrist who knows what to do or the patient who...

Although corneal staining has received extensive interest amongst the academic community, most practitioners do not routinely use fluorescein at aftercare visits. The arguments for not using the agent seem to be somewhat flawed in modern contact lens practice and it is hoped by education and wider communications of the value of staining that more practitioners use it more often.

However, data gathered from annual contact lens fitting surveys demonstrate that fewer than 40% of contact lens wearers over 45 years of age (virtually all of whom can be presumed to suffer a partial or complete loss of accommodation) are prescribed a presbyopic correction. Furthermore, monovision is prescribed as frequently as multifocal lenses. These observations suggest that an optimal solution to the contact lens correction of presbyopia remains elusive.

As opposed to the conventional full thickness penetrating keratoplasty for all corneal disease. This is particularly applicable to corneal endothelial failure where only descemet's membrane with endothelium is removed and replaced. This technique is called descemet membrane endothelial keratoplasty (DMEK). Special techniques are being used to retrieve the donor material which is composed from descemet's membrane and endothelium only. This material forms a roll due its elastic properties and in this form is used in DMEK. Descemet's endothelial rolls are being used for DMEK transplantations .

Older hydrogel CL wearers were also more likely to consider discontinuing CL wear compared with younger hydrogel or silicone hydrogel CL wearers in general. Young adult CL wearers should be routinely queried directly about specific aspects of CL wear in order to determine whether different lens types should be prescribed to avoid abandonment of CL wear.

Family social support is based upon a widening of the responsibility for avoiding eye rubbing to all family members. Some patients will need minimal application of these principles with patient education being sufficient intervention to achieve habit reversal. For patients with strong provocation to rubbing and/or by having a well established rubbing habit, a greater exposure to the habit reversal program described is indicated. Successful habit reversal may slow the rate of ectasia progression.

It is particularly well suited to this task due to its fluorescent properties and its high visibility at low concentrations. Ocular surface fluorescence observed clinically is affected by a number of factors including concentration of fluorescein, thickness of the fluorescein layer, the wavelength of the exciting light source and whether or not a barrier filter is used as part of the viewing system. In this review we have attempted to provide a critical evaluation of the published literature relating to three potential cellular mechanisms involved in corneal surface fluorescence: surface pooling, uptake by cells and ingress around cells.

The consistency in the (inferotemporal) location of the TCC merits further research in this regard to the development of corneal ectasia.

Data that we have gathered from annual contact lens fitting surveys demonstrate a commensurate increase in toric lens fitting as a proportion of all soft lenses fitted. The current toric lens prescribing rate (34% of all lenses when cosmetic tints, monovision and multifocal lenses are ignored) is roughly equivalent to the rate that would be achieved if all cases of astigmatism 1.00D or more were fitted with toric lenses. Toric lenses tend to be fitted more to males and prescribed for monthly rather than daily replacement.

They can therefore be excluded from a simplified recording scheme. A simplified and comprehensive soft contact lens fit recording system could consist of a cross-hairs indicating the centre of the cornea; a circle to indicate the lens centration; a mark on the relevant position of the circle to indicate any limbal incursion; a grade (B) below for movement with blink in up-gaze, a grade (L) to the side for horizontal lag and a grade above (P) for the assessed push-up recovery speed.

Data that we have gathered from annual contact lens fitting surveys over the past 12 years demonstrate that contact lenses are worn, on average, 5.4+/-1.9 days per week. Rigid lenses tended to be worn on a full-time basis, typically seven days per week. The distribution of daily disposable lens wear is bimodal, with peaks at two days and seven days per week of wear. Over the survey period there appears to have been a small trend toward the use of contact lenses on a part-time basis.

As demonstrated in this report of the results of annual UK prescribing surveys conducted over the past 12 years, there has been a steady increase in the use of multi-purpose solutions, which in 2007 represented 93% of all lens care systems prescribed. This increase is attributed to factors such as simplicity, reduced cost and enhanced compliance with these products. The apparent reversal of this trend in 2008 is probably due to an undermining of patient and practitioner confidence in multi-purpose solutions relating to withdrawals of some multi-purpose solutions from the market, and controversies concerning corneal staining with some lens-solut...

In selected cases such as the above, large diameter inverse geometry RGP may be fitted only if the eyelid shape and tension permits so. The first case demonstrates that the option of hydrogel lenses is viable when the patient has no interest in RGPs and in certain cases can improve vision to satisfactory levels. In other cases, graft toricity might be so high that the practitioner will need to employ hydrogel torics with large amounts of cylinder in order to correct ...

However, as documented in this report of the results of annual prescribing surveys conducted over the past 12 years, there has been a steady decline in rigid lens fitting over this period. This is attributed to factors such as the initial discomfort of rigid lenses and the increased sophistication of soft lens materials and designs. There is an apparent trend for rigid lenses to be used more for 'specialist' fits, such as sophisticated toric designs, multifocals and orthokeratology.

The selection of a SiHy material provided increased oxygenation to re-establish corneal integrity. However, selecting the appropriate modulus was an additional factor to consider in this case since it had a direct effect on the visual outcome.

Gentle rubbing may double intraocular pressure. However, the combination of tight eye closure and forceful rubbing may raise intraocular pressure to more than 10 times normal levels. The possibility that, in susceptible individuals, chronic habits of abnormal rubbing may lead to the development or progression of keratoconus has been extended to the possibility of rubbing related adverse responses in other diseases and conditions.

A 2-week contact lens free period seems to be adequate for the cornea to stabilize; however, one cannot predict the minimum time needed for each individual patient. Repeating examinations to document corneal stability before refractive surgery may be a safer alternative.

Risk of complications in contact lens wear increases during overnight wear and may further increase when the treatment is used on children. The aim of this paper is to provide a comprehensive guideline for practitioners to improve their orthokeratology practice and minimize unnecessary or preventable complications. The fundamental requirement for starting an orthokeratology practice is to have proper education in the area and to equip the practice appropriately.

Nationally, practices were varied. The majority of ophthalmology departments continued to use non-disposable tonometer prisms, but few seemed aware of the Royal College of Ophthalmologists' recommendation that disposable prisms are used in patients at risk of prion disease, and few track tonometer heads or replace them according to manufacturers guidelines. Use of disposable tonometer prisms would seem to reduce concerns about sterilisation, as well as prevent spread of common pathogens.
