Abstract
Purpose The study aims to assess the perception of optical spectacles use among the Ha'il region population in Saudi Arabia. Patients and Methods A cross-sectional survey was distributed via various social media applications to the residents of the Ha'il region. An online questionnaire was designed and included informed consent and questions assessing the participants' perceptions about wearing eyeglasses, contact lenses, and general eye health. Results 32.4% of the participants think that long-term eyeglasses wearing worsens vision, and 43% think eyeglasses wearing improves vision. 75.2% believe that long-term use of glasses could cause lifetime dependency on eyeglasses. Regarding contact lenses, 45.9% believe that long-term wearing worsens vision, and 24.1% think long-term wearing of contact lenses improves vision. 60% think long-term use of lenses causes lifetime dependency on those contact lenses. Conclusion Our results highlighted the misconceptions among the study population regarding wearing prescribed eyeglasses and contact lenses. Thus, education programs and media are warranted to correct the misconceptions about spectacles and raise the awareness about refractive errors and treatment options.

Abstract
The study assessed the contact lens prescribing patterns and associated factors in a university optometry clinic in Trinidad and Tobago. The data relating to habitual or new contact lens (CL) prescribing patterns among wearers over a two-year period were reviewed. Pearson’s chi-squared test and logistic regression models were used to analyze the findings. The Hosmer–Lemeshow goodness-of-fit test was used to examine the model calibration. A total of 243 CL fits were analyzed, and the Homeshow–Lemeshow goodness-of-fit test indicated a good fit (χ2 (7) = 7.296, p = 0.399). The mean age of lens wearers was 29.6 ± 12.4 (mean ± SD); the majority, 155 (63.8 %) of whom, were 21 to 40 years old. Most lenses were fitted on females (64.2% of fits overall) and about half of the wearers (n = 122, 50.2%) were prescribed lenses for cosmetic purposes. Conventional soft CL were the most prescribed modality of wear, accounting for 129 (53.1%) of the fits. Age from 21 to 40 years was the predictor of lens type prescribed, and those in that age range were four times more likely to be prescribed soft lenses compared to other ages. The patterns of CL prescribing in a university optometry clinic in Trinidad and Tobago are similar to the global market trends with slight variations.

Demographic profiles of contact lens wearers and their association with lens wear characteristics in Trinidad and Tobago: A retrospective study. PLoS One 2022; 17:e0264659. [PMID: 35867670 PMCID: PMC9307171 DOI: 10.1371/journal.pone.0264659] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Accepted: 07/10/2022] [Indexed: 11/18/2022] Open
Abstract
Purpose
Contact lenses (CL) remain a popular mode of refractive error correction globally and in the Caribbean, mostly among young people. However, no data on the characteristics of the CL population wearers in the Caribbean is available. This study reported on the characteristics of CL wearers and the associated factors in Trinidad and Tobago (T&T).
Methods
This retrospective study reviewed the clinical records of 243 CL wearers who attended the University of the West Indies (UWI) optometry clinic between 2017 and 2018. Data on their demographic profiles, CL wearing characteristics including lens type, material, purpose of wear, replacement schedule and lens care systems were extracted and analyzed. The associations between the demographic characteristics and CL wearing characteristics were also determined.
Results
About half of the CL wearers used them for fashion (more among those aged 18 to 30 years, 61.0%), therapeutic (more among those <18 years, 43.8%, P = 0.001) and refractive error correction purposes (more in those >40 years, P = 0.001). Females were more likely to use CLs for fashion compared with males (67.0% versus 40.7%). Age (P<0.0005) and gender (P = 0.030) were associated with the lens materials. Those aged 18–30 years were more likely use hydrogels compared with the younger ones (64.1% versus 25.0%). Rigid gas permeable (RGP) CL use was more common in males than females (21.8% versus 10.9%, P = 0.031). Daily disposables were predominantly used by younger respondents (18–30 years old, 31.3%, P < 0.001) and more in females than males (66.7% vs 49.4%, P = 0.040).
Conclusion
The study found that the CL appears to be more commonly worn for fashion in younger females and for refractive error correction in older males. Age, gender, and employment status were the main determinants of lens wear among respondents attending the university clinic in T&T.

Abstract
PURPOSE To document contact lens prescribing trends in the United Kingdom over the past quarter of a century. METHODS An annual survey of contact lens prescribing was conducted each year from 1996 to 2020, inclusive, by asking a random selection of optometrists and contact lens opticians to provide information relating to 10 consecutive contact lens fits between January and March. RESULTS Over the 25 year survey period, 2,671 practitioners returned survey forms, reporting a total of 25,575 contact lens fits. The mean (± standard deviation) age of lens wearers was 35 ± 15 years, of which 64 % were female. Over the survey period, rigid lens new fits decreased from 22 % to 2%. The prescribing of silicone hydrogel lenses has increased steadily since their introduction towards the end of the 1990s, and now represent 80 % of soft lens fits. Soft toric lens prescribing has gradually increased to 47 % - a value at which astigmatism ≥ 0.75DC is theoretically corrected in all contact lens wearers. Daily disposable prescribing increased steadily over the survey period and now represents 63 % of lenses prescribed. Extended wear fits remain at very low levels, except for some prescribing for overnight orthokeratology. Multi-purpose lens care solutions are ubiquitous; peroxide and other systems are now seldom prescribed. Rigid lenses and monthly replacement soft lenses are predominantly worn on a full time basis, whereas daily disposable soft lenses are mainly worn part time. CONCLUSIONS This report documents the evolution of contact lens fitting in the United Kingdom over the past 25 years. The most likely lens fit is a spherical design silicone hydrogel daily disposable contact lens prescribed for a 35 year old female and worn on a part-time basis.

Abstract
Evidence-based contact lens -->practice involves finding, appraising and applying research findings as the basis for patient management decisions. These decisions should be informed by the strength of the research study designs that address the question, as well as by the experience of the practitioner and the preferences and environment of the patient. This reports reviews and summarises the published research evidence that is available to inform soft and rigid contact lens history and symptoms taking, anterior eye health examination (including the optimised use of ophthalmic dyes, grading scales, imaging techniques and lid eversion), considerations for contact lens selection (including the ocular surface measurements required to select the most appropriate lens parameter, lens modality and material selection), evaluation of lens fit, prescribing (teaching self-application and removal, adaptation, care regimen and cleaning instructions, as well as -->minimising risks of lens wear through encouraging compliance) and an aftercare routine.

Abstract
Ultraviolet A (UVA) light-based photoactivation of riboflavin (Rf) to induce corneal crosslinking (CXL) and mechanical stiffening is now a well-known treatment for corneal ectasia and Keratoconus that is being used in a topographically guided photorefractive intrastromal CXL (PiXL) procedure to treat low degrees of refractive errors. Alternative approaches for non-invasive treatment of refractive errors have also been proposed that use femtosecond lasers (FS) that provide much faster, more precise, and safer results than UVA CXL. One such treatment, nonlinear optical crosslinking (NLO CXL), has been able to replicate the effects of UVA CXL, while producing a smaller area of cellular damage and requiring a shorter procedure time. Unlike UVA CXL, the treatment volume of NLO CXL only occurs within the focal volume of the laser, which can be placed at any depth and scanned into any pattern for true topographically guided refractive correction. This review presents our experience with using FS lasers to photoactivate Rf and perform highly controlled corneal CXL that leads to mechanical stiffening and changes in corneal shape.

Abstract
BACKGROUND To assess the general knowledge and attitude of refractive error correction methods among female Saudi university students. METHODS One thousand, one hundred and sixty-five female university students, between 17 and 32 years of age were randomly interviewed using self-administered questionnaires with open and closed-ended questions. The questions collected information on demographics (gender, age, educational status, college of study, and occupation), addressed general knowledge/perception of the difference between the professions of ophthalmology and optometry, and attitudes toward spectacle, contact lens (CL) usage, including coloured prescription CLs, and refractive surgery for correcting refractive errors. RESULTS The response rate was 90 per cent (1,052/1,165). Fifty-two per cent had never had an eye examination and only 28 per cent correctly identified the difference between an 'ophthalmologist' and 'optometrist'. Eighty-one per cent knew that CLs instead of spectacles (81.8 per cent), and coloured CLs (89.7 per cent) can be used for correcting refractive errors. Concerning refractive surgery, although a majority (90 per cent) knew that the technique corrects refractive error and reduces dependency on spectacles/CLs, only five per cent had experienced refractive surgery. Approximately, 46 per cent and 47 per cent used spectacles and CLs, respectively, and while the optometrist was the main source of CL prescriptions (41 per cent), most people visited the ophthalmologist for their eye examination (68 per cent). Surprisingly, 52 per cent had never had an eye examination, or had only had one or two eye examinations (50 per cent) in their lifetime. While 23 per cent of spectacle wearers chose to continue with spectacles at the end of the study, 64 per cent and 12 per cent preferred refractive surgery and CLs, respectively, for refractive correction. Lack of information and fear of complications, but not cost, hindered most people from uptake of CLs and refractive surgery. CONCLUSION The students demonstrated high levels of knowledge and awareness of refractive correction methods, especially for refractive surgery. Although many consulted the optometrist or ophthalmologist for their eye examinations and corrective devices, many remain uncorrected and unaware of the main difference between both professions. The lack of information about correction methods and fear of complications may have affected their interest in uptake of eye services and should be addressed to increase uptake and prevent avoidable vision loss.

Abstract
BACKGROUND Contact lens fittings in a hospital-based practice are different from those in private practices because of specialised conditions. Few studies have been published on material preferences of such wearers, especially in long-term wearers. The aim of this study is to document contact lens prescribing trends in a hospital-based practice among long-term lens wearers and to identify their demographic profile. METHODS Subjects reporting to a contact lens clinic of a tertiary eye-care centre in India from 1 January 2014 to 31 December 2014, with a minimum of five years of lens wear, were included in the study. Data were collected retrospectively from the electronic medical charts of these subjects. RESULTS Three hundred and sixty subjects were included in the study. The average duration of contact lens wear among the subjects was 9 ± 5 years (range: 5-35 years). The average age of the subjects was 31.38 ± 11.75 years (age range: 5-78 years). Hydrogel material and soft spherical type were preferred by most of the soft lens wearers (53 per cent). Eighty per cent of subjects followed hand hygiene and cleaning regimen practices. CONCLUSION The preference for monthly replacement lenses and silicone hydrogel material increased over the years. Regular after-care consultations could enforce the need for compliance with hand hygiene and cleaning regimens among lens wearers.

Abstract
AIM To assess the attitude and practice of contact lens (CL) wearers among teenage school students and to evaluate how much the teenagers adhere to the CL care procedures according to the proper care of CL guidelines. METHODS A cross-sectional descriptive study of Italian teenagers from high schools in Rome who wear CL. We inquired about the different aspects of CL care through a questionnaire. RESULTS We investigated 3,106 students from high schools in Rome (2% of all Roman high school students), 293 of whom wore CL (9%); 151 (52%) of participants responded, 42 (27.8%) male and 109 (72.8%) female. The mean age was 16.4 ± 1.6 years. 79.5% of students were daily users. 45.7% wore CL more than nine hours/day. 87.4% wore soft CL. 33.1% wore disposable CL; 7.9% weekly CL, 55% monthly CL. Thirty-four percent wore disposable lenses twice or more. 14.5% of students did not wash their hands before handling CL and 52.3% wore CL after it had fallen in the sink. 39.7% rubbed and cleaned CL before storing it. 10% used expired lens care solutions. Only 31.1% changed CL cases every three months. 38.4% wore CL in a swimming pool. 61.6% were having problems: redness (13.9%), itching (7.9%), and foreign body sensation (29.1%). CONCLUSION Many students don't properly care for their CL. Education regarding proper care and management of CL among users is advised in view of frequency of symptoms and complications reported.

Abstract
PURPOSE To evaluate the impact of contact lenses wear vs. spectacles wear on visual function of young adults with mild to moderate myopia. METHODS 57 students (27 male and 30 female) with a mean age of 23 years old participated in the study. Their mean best corrected visual acuity was 10/10 binocularly, all suffered from mild to moderate myopia (-3.75 sph/SD 1.25 sph) and they were both contact lenses and spectacles wearers. The VF-14 questionnaire was administered to assess the contact lenses wear vs. spectacles wear impact score on general daily living among the young individuals. It was used translated in Greek after following the 'translation-back translation' procedure. RESULTS The mean VF-14 score among spectacles and contact lenses wearers was 100 and 86.78 (SD 4.08) respectively. Although there was a significant difference between the two groups (p<0.05), both scores were related to a satisfactory functional vision for daily living. The contact lenses wearers were facing difficulty especially while driving at night, seeing steps, as well as doing fine handwork (i.e. sewing, knitting or carpentry). CONCLUSIONS The use of both spectacles and contact lenses provides satisfactory visual functioning for daily activities in young individuals suffering from mild to moderate myopia. However, there is a spectacles' wear superiority in personal satisfaction when compared to contact lenses.

Abstract
PURPOSE The purpose of this study was to investigate the effect of lens care products on short-term subjective and physiological performance silicone hydrogel lenses. METHODS Ten subjects wore either lotrafilcon B or galyfilcon A silicone hydrogel contact lenses soaked in a lens care product containing either Polyquad/Aldox or PHMB or control lenses inserted directly from the pack. Subjects wore the lenses for 6 h. Ocular comfort (graded on a 1 to 10 scale) and ocular physiology were assessed. Unworn but soaked lenses were analyzed for metrological changes, release of excipients into phosphate buffered saline, and changes to their surface chemical composition. RESULTS None of the lens metrology measures or clinically observed conjunctival or limbal redness changed. Corneal staining was significantly (p < 0.008) raised, albeit to low levels, after 6 h wear for either lens type when soaked in the PHMB solution compared with the control lens (lotrafilcon B 0.4 to 0.9 ± 0.7 to 0.4 vs. 0.1 to 0.4 ± 0.3 to 0.5; galyfilcon A 0.2 to 0.3 ± 0.2 to 0.4 vs. 0.0 ± 0.0). For lotrafilcon B lenses, there were decreases in comfort (p = 0.002), increases in burning/stinging (p = 0.002) after 1 h of wear, and increases in lens awareness on lens insertion (p = 0.0001) when soaked in PHMB. However, lotrafilcon B lenses soaked in Polyquad/Aldox showed increases in burning/stinging after 1 and 6 h (p < 0.008) of lens wear. For galyfilcon A lenses, most significant (p ≤ 0.002) changes to symptomatology occurred after soaking in Polyquad/Aldox solution. More PHMB was released from lotrafilcon B lenses, and more MPDS material was released from galyfilcon A lenses. The surface of galyfilcon A lenses changed but irrespective of lens solution type, whereas the changes to the lens surface was dependent on solution type for lotrafilcon B lenses. CONCLUSIONS Lens care products can change corneal staining and comfort responses during wear. These changes may be associated with release of material soaked into lenses or changes to the lens surface composition.

Abstract
The use of contact lens (CL) for the correction of refractive errors, cosmetic use and their usage as a therapeutic modality for corneal pathologies has increased tremendously over the years. The present study was conducted with the aim to find a pattern of CL use amongst college students with a focus on the rationale for CL use and problems related to their use. This study includes 371 college students who were current users of CL at the time of the study. Results showed that 96.8% of the CL users use the ‘daily wear type’ of CL. Most quoted reasons of usage were comfort and convenience (61.2%) with cosmetic benefit (42.9%) as the next most common reply. Common complaints were that of general discomfort (foreign body sensation), dry eyes and watering eyes. Educated use of CLs amongst its users is advised in view of the symptoms and associated complications that may occur.

Abstract
PURPOSE To evaluate the standards of contact lens practice in Portugal, with particular attention paid to the characteristics of first fits and refits regarding aspects such as symptoms of dryness, overnight wear, silicone hydrogel and multifocal prescriptions, and care systems. METHODS A questionnaire was distributed to 300 contact lens practitioners in Portugal, and they were asked to complete them with the following first 10 fittings (only right eye of each patient). Fifty-six questionnaires were returned to total 529 fittings. RESULTS The mean age of contact lens wearers was 28.1 +/- 10.1 years, and 94.4% of the wearers were fitted with soft contact lenses (67.9% hydrogel lenses, 21.2% silicone hydrogel lenses, and 5.2% biomimetic soft contact lenses). Sixty percent of patients wore their contact lenses for 9 to 12 hours per day. The lenses were replaced on a monthly basis in 71% of cases, and 82.8% of wearers used a multipurpose solution for lens cleaning and disinfection. Significant differences were found between first fits and refits regarding the prevalence of dryness symptoms (higher incidence of frequent symptoms in the evening in the refitting group, P<0.01, chi2), replacement schedule (lower incidence of monthly disposable lenses in refits compared to first fits, P<0.05, chi2), and care regimen (lower incidence of multipurpose solutions and higher incidence of hydrogen peroxide in refits, P<0.01, chi2). CONCLUSIONS Statistical analysis of the current trends in the Portuguese contact lens fitting profile showed that contact lens practitioners in Portugal are receptive to use innovations in contact lens products, such as silicone hydrogel and biomimetic materials, and daily-disposable contact lenses to refit patients who have not succeeded with previous lenses. Multifocal lenses also experienced a significant increase in their prevalence among refits and new fits. Rigid gas-permeable materials maintained and even experienced a slight increase in refits. Conversely, there is still a low incidence of extended-wear prescriptions, most of them being made with low-Dk soft contact lenses.

Abstract
PURPOSE To document contact lens prescribing trends in the United Kingdom over the past decade (between 1996 and 2005). METHODS An annual survey of contact lens prescribing trends was conducted each year by asking a random selection of optometrists and dispensing opticians to provide information relating to 10 consecutive contact lens fits between January and March. RESULTS Over the 10-year survey period, 1251 practitioners returned survey forms representing a total of 12,050 contact lens fits. The mean (+/-standard deviation) age of lens wearers was 33+/-13 years of which 64% were female. Over the survey period, rigid lens new fits decreased from 22% to 4%. Low water content lenses reduced from 20% to 2% of new soft lens fits. Soft toric lenses gradually increased to the point where they accounted for the expected proportion of patients with astigmatism>or=1.00DC (i.e. >20% of soft lens fits). Monthly and daily disposable lenses accounted for >90% of all soft lens fits between 2003 and 2005. The proportion of new soft fits and refits prescribed as extended wear has gradually increased, stabilizing at about 5% of new fits and 12% of refits. Multi-purpose lens care solutions increased from 60% of all care systems in 1997 to 91% in 2005. Rigid lenses and monthly replacement soft lenses are predominantly worn on a full time basis, whereas daily disposable soft lenses are mainly worn part time. CONCLUSIONS This survey indicates that technological advancements such as the development of new lens materials, manufacturing methods and lens designs have had a significant impact on the contact lens market over a relatively short period of time.
