“…But most of the results also emphasize on the deep approach to learning. 12 - 14 A study by Samarakoon and colleagues 10 that included the first and final year of medical undergraduate, postgraduate and trainee students observed that the learning approach was strategic with the VARK and ASSIST (Approaches to study skills Inventory for students) questionnaires.…”

ObjectivesTo assess learning approaches of 1st, 2nd, and 3rd-year medical students by using revised two-factor study process questionnaire, and to assess reliability and validity of the questionnaire.MethodsThis cross-sectional study was conducted at the College of Medicine, Riyadh, Saudi Arabia in 2014. The revised two-factor study process questionnaire (R-SPQ-2F) was completed by 610 medical students of both genders, from foundation (first year), central nervous system (second year), medicine and surgery (third year) courses. The study process was evaluated by computing mean scores of two research study approaches (deep & surface) using student’s t-test and one-way analysis of variance. The internal consistency and construct validity of the questionnaire were assessed using Cronbach’s α and factor analysis.ResultsThe mean score of deep approach was significantly higher than the surface approach among participants(t(770)=7.83, p= 0.000) for the four courses. The mean scores of deep approach were significantly higher among participants with higher grade point average (F(2,768)=13.31, p=0.001) along with more number of study hours by participants (F(2,768)=20.08, p=0.001). The Cronbach’s α-values of items at 0.70 indicate the good internal consistency of questionnaire used. Factor analysis confirms two factors (deep and surface approaches) of R-SPQ-2F.ConclusionsThe deep approach to learning was the primary approach among 1st, 2nd and 3rd-year King Saud University medical students. This study confirms reliability and validity of the revised two-factor study process questionnaire. Medical educators could use the results of such studies to make required changes in the curriculum.

“…Patient satisfaction, visual symptoms and spectacle independence questionnaires were also administered at both the 1-month and 3-month visits. The patient reported spectacle independence questionnaire (PRSIQ) 14 was used to determine subjects’ need for spectacles or contact lenses and their satisfaction with vision at various distances. Visual symptoms were reported using a proprietary patient-reported visual symptom questionnaire.…”

Purpose To evaluate the vision, defocus curve, reading speed and patient satisfaction after implantation of an extended depth of focus (EDOF) IOL in one eye and a diffractive multifocal in the fellow eye. Setting One clinical practice in the USA. Design Prospective unmasked non-randomized clinical trial. Methods Subjects presenting for routine cataract surgery interested in reducing their dependence on spectacles were enrolled. Study endpoints included uncorrected and distance-corrected binocular distance (4 m), intermediate (66 cm) and near (40 cm) visual acuity at 3 months. Additional endpoints included the residual refraction, spectacle independence, overall satisfaction with vision, visual symptoms, reading speed and defocus curve. Results With a best distance correction, 77% (30/39) of subjects had 20/25 or better VA at distance, intermediate and near and nearly all subjects had 20/32 or better VA at all three distances. Defocus curve results showed mean continuous vision of 20/25 or better from plano to −2.50 D. Nearly 80% (31/39) of subjects had 20/25 visual acuity from 0.00 D to −2.50 D. The critical print size was between 0.3 and 0.4 logMAR (20/40 to 20/50 Snellen Equivalent). Spectacle independence was 100% at distance, 95% at intermediate and approximately 70% at near. The percentage of subjects who were “not at all” or “slightly” bothered by visual disturbances ranged from 64% (16/25) for Halos to 88% (22/25) for Starbursts. Conclusions EDOF/bifocal IOL blended implantation results in at least 20/25 mean visual acuity from distance to near with good spectacle independence and low reports of severe visual disturbances.

“…In an effort to quantify the functional benefits of the visual gain at intermediate distance provided by this new lens design, Mencucci et al 24 also evaluated spectacle independence using a self-reported, binocular subjective questionnaire: the Patient Reported Spectacle Independence Questionnaire. 25 The results showed that patients implanted with the new lens design were more spectacle independent for intermediate than those implanted with the standard aspheric monofocal IOL; 20% of the patients implanted with the new lens design reported the need for intermediate correction in their everyday life versus 90% of the patients implanted with the standard aspheric monofocal IOL. 24 Additionally, the patients implanted with the new lens design reported a lower frequency of use of spectacles compared to the patients implanted with the standard aspheric monofocal IOL.…”

“…Intermediate vision is becoming more important in the modern world thanks to everyday tasks such as the use of computers and tablets, playing sports, viewing the speedometer in a car, and walking on uneven surfaces. [23][24][25][26][27] To target this unmet need of patients with monofocal cataract, we have introduced a new refractive IOL technology that is designed to improve intermediate vision compared to the standard aspheric monofocal IOLs. Based on simulations and optical bench testing, and reinforced by the clinical data, 24 we conclude that the new lens design provides increased visual acuity in the intermediate range compared to an aspheric monofocal IOL.…”

B efore the introduction of the aspheric technology, the standard of care was the use of monofocal spherical intraocular lenses (IOLs) that have spherical optical surfaces that are well known to induce (positive) primary spherical aberration. The spherical aberration of spherical IOLs adds to the spherical aberration originating from the cornea, increasing the total spherical aberration of the eye and limiting the distance image quality of the pseudophakic eye. 1-3 Aspheric IOLs have been developed to either compensate for the lens' intrinsic spherical aberration ("aberration neutral" or "zero aberration" IOLs) or the corneal spherical aberration (aberration-correcting IOL). 3 Previous studies have shown that aspheric IOLs that fully ABSTRACT PURPOSE: To describe and evaluate a new monofocal intraocular lens (IOL) designed to improve intermediate vision using a unique refractive technology. METHODS: The new monofocal lens is based on a higher order aspheric optic and is designed to improve intermediate vision. Simulated visual acuity from far to-2.00 diopters (D) was calculated using optical bench data. The effect of corneal higher order aberrations (HOAs) on simulated visual acuity, pupil size, and decentration was assessed using realistic computer eye models. The susceptibility to photic phenomena was evaluated by measuring preclinically the intensity of the light distribution in the retinal plane. The new lens design was compared to a standard aspheric monofocal IOL that shares the same platform, material, and primary spherical aberration as the new design. RESULTS: Simulated defocus curves showed increased simulated visual acuity in the intermediate range compared to a standard aspheric monofocal IOL with comparable distance vision, independently of the pupil size and corneal HOAs. At-1.50 D, the new IOL design provided a gain of approximately 0.1 logMAR, whereas at distance, the difference was less than 0.05 logMAR. The tolerance to decentration was also similar in both designs. Finally, experimental results indicate that the susceptibility to photic phenomena with the new lens design was similar to that of a standard aspheric monofocal IOL. CONCLUSIONS: Preclinical data showed that the new lens design improves intermediate vision while maintaining comparable distance image quality and keeping the same photic phenomena profile as a standard aspheric monofocal IOL.
