Purpose: To assess public awareness and knowledge about presbyopia and their compliance to ocular examination in Jordan.

Patients And Methods: A cross-sectional survey was designed to interview people in different provinces of Jordan. Socio-demographic data such as age, gender and level of education and region was reported.

BCLA CLEAR Presbyopia: Evaluation and diagnosis.

It is important to be able to measure the range of clear focus in clinical practice to advise on presbyopia correction techniques and to optimise the correction power. Both subjective and objective techniques are necessary: subjective techniques (such as patient reported outcome questionnaires and defocus curves) assess the impact of presbyopia on a patient and how the combination of residual objective accommodation and their natural DoF work for them; objective techniques (such as autorefraction, corneal topography and lens imaging) allow the clinician to understand how well a technique is working optically and whether it is the right choice or how adjustments can be made to optimise performance. Techniques to assess visual performance and adverse effects must be carefully conducted to gain a reliable end-point, considering the target size, contrast and illumination.

Assessment of knowledge, perception, and practice patterns of Jordanian optometrists during COVID-19 pandemic: a cross-sectional online survey.

Aim: To investigate knowledge, risk perception, and attitude towards corona virus disease 2019 (COVID-19) and infection control measures among optometrists in Jordan.

Methods: A cross-sectional survey was distributed through social media platforms to optometrists registered with the Jordanian syndicate and Jordanian association of optics. Information on participants' socio-demographic characteristics, knowledge of clinical features of COVID-19, risk assessment and infection control measures for preventing disease transmission were collected.

Perceptions of potential barriers to soft contact lens wear among university students in Jordan.

Clinical Relevance: Identifying potential barriers to contact lens wear could increase awareness about contact lenses and their benefits and boost the confidence of optometrists offering contact lenses to their patients.

Background: Contact lenses provide better visual performance according to many studies. Nevertheless, resistance to wearing them remains an issue.

The effects of tobacco waterpipe smoking on the ocular surface.

Clinical Relevance: This study was conducted to determine the effect of tobacco waterpipe smoking on the ocular surface. The findings could be useful in understanding ocular surface changes and associated symptoms in waterpipe smokers.

Background: Tobacco smoking has been reported to have many systemic and ocular adverse effects.

Public attitudes toward corneal donation in northern Jordan.

Purpose: The aims of this study were to assess the knowledge and attitude toward corneal donation among Jordanian population and to report the reasons which may influence subject's decision and attitude toward corneal donation.

Methods: A self-designed questionnaire was developed. The participants were asked about reasons for both willingness and unwillingness to donate their corneas.

Clinical characteristics and causes of visual impairment in a low vision clinic in northern Jordan.

Aim: The aim of the study was to identify causes of visual impairment among patients attending a low vision clinic in the north of Jordan and to study the relevant demographic characteristics of these patients.

Subjects And Methods: The retrospective study was conducted through a review of clinical records of 135 patients who attended a low vision clinic in Irbid. Clinical characteristics of the patients were collected, including age, gender, primary cause of low vision, best corrected visual acuity, and current prescribed low vision aids.

Patient-related barriers to Rigid Gas Permeable (RGP) lens wear among keratoconus patients in Jordan.

Purpose: To assess potential patient-related barriers to rigid gas permeable (RGP) lens wear for vision rehabilitation in a sample of keratoconus (KC) patients in Jordan.

Methods: Barriers for RGP contact lens wear among KC patients were discussed and specified by a focus group which consisted of five optometrists who are involved in contact lens practice. The focus group addressed potential barriers for RGP lens wear from the patient's perspective.

Awareness of diabetic retinopathy among patients with type 2 diabetes mellitus in Jordan.

Background: Increasing the level of awareness of diabetic retinopathy among individuals with type 2 diabetes mellitus is considered an important factor for early diagnosis and management of diabetic retinopathy. The aim of this study was to evaluate awareness of diabetic retinopathy among a sample of type 2 diabetes mellitus patients in Jordan.

Patients And Methods: The study period was from August to December 2015.

Public awareness of common eye diseases in Jordan.

Background: Cataract, glaucoma, diabetic retinopathy and dry eye disease are common with high prevalence in Jordan. This study aims to assess the awareness of these ocular diseases among Jordanian population.

Method: A self-designed questionnaire was developed in Arabic and used to interview people in different provinces of Jordan.

Trends of contact lens prescribing in Jordan.

Purpose: To evaluate contact lens prescribing trends among optometrists in Jordan.

Methods: Optometrists from 173 practices in Jordan were surveyed about prescribing contact lenses in their practice. Practitioners were required to record information for the last 10 patients that visited their practice.

Epidemiology of symptoms of dry eye disease (DED) in Jordan: A cross-sectional non-clinical population-based study.

Purpose: To describe the prevalence of dry eye disease (DED) symptoms and to identify associated risk factors in a general non-clinical population in Jordan.

Methods: In this cross-sectional study, participants were selected randomly from the general non-clinical population in Jordan. Participants aged 18 years or over completed the Arabic version of Ocular Surface Disease Index (OSDI) questionnaire on dry eye symptoms.

Contact lens in vitro wettability by interferometry measures of drying dynamics.

Purpose: To develop with a thin film interferometer new parameters to describe the drying properties of contact lenses; these are: time to first break-up (onset latency), duration of lens surface drying (drying duration), maximum speed of increase in the drying area (maximum speed), and the time to reach maximum drying speed (peak latency). These new parameters were compared with the contact angle (CA) measurement of contact lenses by the captive bubble (CB) technique.

Methods: A thin film interferometer was connected to a digital camera, which captured images of the pre-lens liquid film of seven soft contact lenses in vitro: 1-Day Acuvue Moist, ACUVUE Oasys (Johnson & Johnson Vision Care); SofLens 38, PureVision (Bausch & Lomb); AirOptix Night & Day, AirOptix Aqua (CIBA Vision, Corp); and Proclear (Cooper Vision).

A novel on-eye wettability analyzer for soft contact lenses.

Purpose: To develop novel methodology to assess two in vivo wettability parameters, contact angle and index of liquid spreading (ILS), for hydrogel contact lenses and to provide a comprehensive investigation of the measurement errors (repeatability) associated with these two parameters.

Methods: A Novel On-eye Wettability Analyzer (NOWA) was constructed which delivered a drop of 0.4% sodium hyaluronate mixed with sodium fluorescein directly on to a lens surface in vivo while a two-camera digital system recorded both the resultant contact angle and liquid spreading.
