Contact lens-related complications might range from harmless irritation to sight-threatening reactions. The key to prevention other than adhering to good hygiene is preliminary eye examinations and timely aftercare assessments. A retrospective analysis of 33 patient clinical records at the university clinic was performed to determine the ocular complications among soft contact lens wearers and its risk factors. Overall, findings indicate that conjunctival hyperemia was the most prevalent complication. Poor lens fit was associated with limbal injection and CLPC. Sleeping with lenses was the most non-compliant behaviour. Eyecare practitioners need to be alarmed by these risk parameters among the young wearers.

Lens Wear

Non-compliance in contact lens wear poses risks for microbial infection. Understanding the scope and extent of non-compliance behaviour is vital for eye care practitioners in deciding which aspect of lens care is critical when consulting patients. A survey was done to assess the level and scope of non-compliance behaviour among 66 young contact lens wearers. Overall, more than half of the participants (52%) did not comply with lens wear and care regimens. The most non-compliant behaviour was the lens cleaning procedure (59%). Eye care practitioners need to establish creative guidelines to improve compliance among the young lens wearers.   Keywords: Contact lens; Compliance; Students; Lens care.   eISSN: 2398-4287© 2020.

ObjectiveMicrobial keratitis is a sight-threatening complication of contact lens wear, which affects thousands of patients and causes a significant burden on healthcare services. This study aims to identify compliance with contact lens care recommendations and identify personal hygiene risk factors in patients who develop contact lens-related microbial keratitis.Methods and analysisA case–control study was conducted at the University Hospital Southampton Eye Casualty from October to December 2015. Two participant groups were recruited: cases were contact lens wearers presenting with microbial keratitis and controls were contact lens wearers without infection. Participants underwent face-to-face interviews to identify lens wear practices, including lens type, hours of wear, personal hygiene and sleeping and showering in lenses. Univariate and multivariate regression models were used to compare groups.Results37 cases and 41 controls were identified. Showering in contact lenses was identified as the greatest risk factor (OR, 3.1; 95% CI, 1.2 to 8.5; p=0.03), with showering daily in lenses compared with never, increasing the risk of microbial keratitis by over seven times (OR, 7.1; 95% CI, 2.1 to 24.6; p=0.002). Other risks included sleeping in lenses (OR, 3.1; 95% CI, 1.1 to 8.6; p=0.026), and being aged 25–39 (OR, 6.38; 95% CI, 1.56 to 26.10; p=0.010) and 40–54 (OR, 4.00; 95% CI 0.96 to 16.61; p=0.056).ConclusionThe greatest personal hygiene risk factor for contact lens-related microbial keratitis was showering while wearing lenses, with an OR of 3.1, which increased to 7.1 if patients showered daily in lenses. The OR for sleeping in lenses was 3.1, and the most at-risk age group was 25–54.

Most of the complications on a Lasik surgery happen during flap cut. Partial or irregular flaps, buttonholes, epithelial defects and free flaps. Risk factors for these complications include increased age, preoperative hyperopia, and years of contact lens wear. In order to avoid these complications I suggest following these steps before each surgery

Purpose: To compare the morphological changes in the meibomian glands and meibomian glands loss between contact lens and non-contact lenses wears in a young population. The contact lens wearers wore C.L. for max 6 years. Methods: Examination of the meibomian gland (MG) by using a corneal topographer CSO MODI 2 incorporating Phoenix-Meibography Imaging software module from January to June 2019. 80 volunteered students of the University of West Attics participated, and all the subjects selected had no obvious ophthalmological symptoms, aged 19 to 22 years. Results: The Arithmetic mean of Meiboscore for those who did not wear C.L. was 1,23 MGL, while for the C.L. wearers was 2,53 MGL. Conclusion: This Clinical research compares the meiboscore of contact lens wearers at a young age (min. 4 years contact lens wearers) and those who never tried to wear. This study showed that there is a relation between meibomian glands loss (MGL) and contact lens wear. Our observations showed that there a small but positive correlation, as the total period of C.L. wear increases the meiboscore increases. In addition, cumulative frequency % showed this slight increase in meiboscore.

Background/aim: To examine the risk factors, clinical characteristics, outcomes and prognostic factors of bacterial keratitis (BK) in Nottingham, UK. Methods: This was a retrospective study of patients who presented to the Queens Medical Centre, Nottingham, with suspected BK during 2015-2019. Relevant data, including the demographic factors, risk factors, clinical outcomes, and potential prognostic factors, were analysed. Results: A total of 283 patients (n=283 eyes) were included; mean age was 54.4+/-21.0 years and 50.9% were male. Of 283 cases, 128 (45.2%) cases were culture-positive. Relevant risk factors were identified in 96.5% patients, with ocular surface diseases (47.3%), contact lens wear (35.3%) and systemic immunosuppression (18.4%) being the most common factors. Contact lens wear was most commonly associated with P. aeruginosa whereas Staphylococci spp. were most commonly implicated in non-contact lens-related BK cases (p=0.017). At presentation, culture-positive cases were associated with older age, worse presenting corrected-distance-visual-acuity (CDVA), larger epithelial defect and infiltrate, central location and hypopyon (all p<0.01), when compared to culture-negative cases. Hospitalisation was required in 57.2% patients, with a mean length of stay of 8.0 +/- 8.3 days. Surgical intervention was required in 16.3% patients. Significant complications such as threatened/actual corneal perforation (8.8%), loss of perception of light vision (3.9%), and evisceration/enucleation (1.4%) were noted. Poor visual outcome (final corrected-distance-visual-acuity of <0.6 logMAR) and delayed corneal healing (>30 days from initial presentation) were significantly affected by age >50 years, infiltrate size >3mm, and reduced presenting vision (all p<0.05). Conclusion: BK represents a significant ocular morbidity in the UK. Culture positivity is associated with more severe disease at presentation but has no significant influence on the final outcome. Older age, large infiltrate, and poor presenting vision were predictive of poor visual outcome and delayed corneal healing, highlighting the importance of primary prevention and early intervention for BK.

Background/aimsTo investigate the chronological corneal changes associated with long-term rigid gas-permeable contact lens (RGP-CL) wear in patients with keratoconus (KC).MethodsClinical records of 405 patients with KC or with KC suspect were retrospectively reviewed. Patients with mild-to-moderate KC and uneventful follow-up were classified into the CL (RGP-CL wear) and non-CL (without CL wear) groups. Inclusion criteria were (1) at least 3-year follow-up and (2) Scheimpflug-based corneal imaging examination at each visit. The anterior (ARC) and posterior (PRC) radius of curvature obtained in a 3.0 mm optical zone, the thinnest pachymetry reading of the corneal thickness (Tmin), and maximum keratometry values (Kmax) were investigated as tomographic parameters.ResultsTwenty-two and 15 patients who met the inclusion criteria were included in the CL and non-CL groups, respectively (31 and 20 eyes, respectively). The mean observation periods were 75 (CL group) and 63 (non-CL group) months. A multivariable non-linear regression analysis to assess the change in tomographic parameters over the follow-up period and difference of the trend between the two groups demonstrated no significant differences in the chronological change in ARC, PRC and Tmin between the CL and non-CL groups (p=0.318, p=0.280 and p=0.874, respectively).ConclusionBased on corneal tomographic evaluation over 5–6 years, the effects of long-term RGP-CL wear had no effect on KC progression.

Purpose. To evaluate the recent trends in demographics, risk factors, and microbiological profiles of microbial keratitis at a university hospital in Hong Kong. Design. Retrospective review. Methods. The medical records of 51 patients admitted to the Prince of Wales Hospital for microbial keratitis from January 2010 to June 2012 were reviewed. Demographics, risk factors, clinical features, microbiological results, and treatment were recorded. Data was analyzed and compared to our historical sampled data collected 11 years ago. Results. The mean age of patients was 41.6 ± 20.3 years. Contact lens use was the major risk factor (45%), followed by injury (12%). The culture positive rate was 59%, of which 37% were Gram-positive organisms and 53% were Gram-negative organisms. Pseudomonas aeruginosa (50%) and coagulase-negative Staphylococcus (13%) were the most commonly isolated pathogens. No resistance to fluoroquinolones was identified. Conclusions. Our study showed that contact lens wear remained the major risk factor for microbial keratitis in Hong Kong and Pseudomonas aeruginosa remained the commonest bacterium isolated. This is comparable to our historical data and other studies conducted in East Asia.

Lens Wear

Contact lenses are lenses placed on the surface of the cornea to correct refractive errors such as myopia (short-sightedness), hyper­metropia (far-sightedness) and astigmatism. Lens-related complications are becoming a greater health concern as increasing number of individuals are using them as an alternative to spectacles. Contact lenses alter the natural ocular environment and reduce the efficacy of the innate defences. Although many complications are minor, microbial keratitis is potentially blinding and suspected cases should be rapidly diagnosed and referred to an ophthalmologist for treatment. Several risk factors have been identified with extended wear, poor hand hygiene, inadequate lens and lens-case care being the most significant. Promotion of good contact lens hygiene and practices are essential to reduce the adverse effects of contact lens wear.
