| 1 | Potential of video games for the promotion of neuroadaptation to multifocal intraocular lenses: a narrative review显示文摘Multifocal intraocular lenses(IOLs) are currently usually implanted for the treatment of cataracts because they have been proved to be superior to monofocal IOLs with respect to spectacle independence. In turn, they are associated with a higher prevalence of dysphotopsia symptoms that is one of the most common causes of patient dissatisfaction. Neuroadaptation seems to play a major role in the optimal adaptation to multifocal IOLs. In this context, the development of strategies that facilitate the neuroadaptation process to multifocality might be an effective strategy to reduce patients' dissatisfaction. Video games have been proved to be effective for the improvement of visual acuity and for the promotion of neuroplasticity in elderly subjects and other populations with cortical-related visual impairment. This narrative review highlights the physiological potential of video games as a perceptual strategy to improve visual acuity and promote neuroplasticity in patients using multifocalIOLs, although research is still needed to confirm these benefits in this specific population, with only one comparative study to this date providing evidence of them. | Maria Begona Coco-Martin Pedro LValenzuela Miguel JMaldonado-López Alejandro Santos-Lozano Ainhoa Molina-Martin David P Pinero | 2019 | International Journal of Ophthalmology(English edition)2019，12，11： | 2 |
| 2 | Profitability analysis of a femtosecond laser system for cataract surgery using a fuzzy logic approach显示文摘AIM:To define the financial and management conditions required to introduce a femtosecond laser system for cataract surgery in a clinic using a fuzzy logic approach.METHODS:In the simulation performed in the current study,the costs associated to the acquisition and use of a commercially available femtosecond laser platform for cataract surgery(VICTUS,TECHNOLAS Perfect Vision GmbH,Bausch & Lomb,Munich,Germany) during a period of 5y were considered.A sensitivity analysis was performed considering such costs and the countable amortization of the system during this 5y period.Furthermore,a fuzzy logic analysis was used to obtain an estimation of the money income associated to each femtosecond laser-assisted cataract surgery(G). RESULTS:According to the sensitivity analysis,the femtosecond laser system under evaluation can be profitable if 1400 cataract surgeries are performed per year and if each surgery can be invoiced more than $500.In contrast,the fuzzy logic analysis confirmed that the patient had to pay more per surgery,between $661.8 and $667.4 per surgery,without considering the cost of the intraocular lens(IOL).CONCLUSION:A profitability of femtosecond laser systems for cataract surgery can be obtained after a detailed financial analysis,especially in those centers with large volumes of patients.The cost of the surgery for patients should be adapted to the real flow of patients with the ability of paying a reasonable range of cost. | Jose Antonio Trigueros David P Pinero Mahmoud M Ismail | 2016 | International Journal of Ophthalmology(English edition)2016，9，7： | 1 |

| 4 | Prevalence of visual impairment and refractive errors in an urban area of Mexico显示文摘AIM: To determine the distribution of refractive errors in a school-age population in Quintana Roo(Mexico) in the framework of an international cooperation campaign for the prevention of blindness. METHODS: A sample of 2647 school-age children(ranging from 5 to 14 years old) with a mean age of 9.1±1.9 years old were tested by trained volunteers for distance visual acuity(VA) and refractive errors. The first screening examination included uncorrected distance visual acuity(UDVA) and VA with a +2.00 D lens. Inclusion criteria for a second complete cycloplegic eye examination performed by an optometrist were UDVA <20/25(0.10 logMAR or 0.8 decimal) and/or VA with +2.00 D ≥20/25.RESULTS: A total of 633(23.9%) children underwent the second complete eye examination. Mean logMAR UDVA was 0.035±0.094(range 1.00 to 0.00 logMAR) for the right eyes and 0.036±0.160(range 1.00 to 0.00 logMAR) for the left eyes. Bilateral amblyopia was found in 17 children(2.7% of refracted eyes;0.64% of the total). The main reason for visual impairment(VI) in the sample analyzed was found to be refractive errors. In 12 children(1.9% of refracted eyes;0.45% of the total) the VI was bilateral and 9(1.4% of refracted eyes;0.34% of the total) achieved a corrected distance visual acuity of 20/25 or better in both eyes. Mean magnitude of sphere and refractive cylinder was +0.20±0.96 D and-0.43±0.85 D in right eyes, and +0.24±1.08 and-0.43±0.83 D in left eyes. The proportion of myopic eyes [standard equivalent(SE) ≤-0.50 D] was 4.6% of the whole sample(5290 eyes). The mean magnitude of myopia was-0.84±3.44 D for the right eyes and-0.82±5.21 D for the left eyes. The proportion of hyperopic patients(SE≥+2.00 D) was 2.4%(15/633), which corresponded to 0.60% of the whole sample(32/5290 eyes). No statistically significant correlation of age to manifest sphere or cylinder was found.CONCLUSION: VI due to uncorrected refractive errors can be easily corrected with glasses but it is still a burden to be treated. Myopia is prevalent in this sample. More efforts towards correcting uncorrected refractive errors are needed. | Isabel Signes-Soler David P Pinero Milagro Ines Murillo Silvia Tablada | 2019 | International Journal of Ophthalmology(English edition)2019，12，10： | 1 |
| 5 | Characterization of the geometric properties of the sclero-conjunctival structure: a review显示文摘To revise the peer-reviewed literature on geometric properties of the scleral-conjunctival structure in order to define their clinical relevance and the potential relationship between their changes and myopia development or progression.A bibliographic search focused on the study of the geometry of conjunctiva and/or sclera as well as those studies evaluating the relationship between geometric changes in the scleral-conjunctival structure and myopia was carried out.Several studies have been performed with different diagnostic technologies,including optical coherence tomography,profilometry and Scheimpflug imaging,to detect geometric changes of the scleralconjunctival tissue in different physiological conditions of the eye,after use of contact lenses and in different ocular pathologies.Likewise,these technologies have been shown to be a valuable clinical tool to optimize scleral contact lens fitting.Future studies should investigate new potential clinical applications of such technologies,including the evaluation of anterior scleral changes related to myopia,as well as to define standardized clinical standard operating procedures for obtaining accurate and reproducible clinical measurement of the scleral-conjunctival morphology. | Laurent Bataille David P Pinero | 2020 | International Journal of Ophthalmology(English edition)2020，13，9： | 0 |
