    Comparison of the impact of nesofilcon A hydrogel contact lens on the ocular surface and the comfort of presbyopic and non-presbyopic wearers
    (Press of International Journal of Ophthalmology, 2019) Lorente Velázquez, Amalia; García Montero, María; Gómez Sanz, Fernando Javier; Rico del Viejo, Laura; Hernández Verdejo, José Luis; Madrid Costa, David
    AIM: To assess and compare the impact of a daily disposable contact lens (CL) with high water content on the ocular surface and comfort of the presbyopic and non-presbyopic population after one day of use. METHODS: Totally 20 presbyopes and 30 non-presbyopes non-contact wearers were fitted with nesofilcon A CLs. CL thickness was measured to assess material stability during daily wear, and ocular surface parameters were also assessed. Optical quality was analyzed for all cases. In addition, CL comfort was rated. RESULTS: No significant differences were found in CL thickness, tear film osmolarity, average tear break-up time, bulbar redness, central corneal thickness, corneal volume, root-mean-square of higher-order aberrations (RMS of HOAs) and vertical and horizontal coma, either as a function of the group or time of use. A significant decrease in tear meniscus height and first break-up of the tear film was found in the presbyopic group (P=0.038; P=0.007 respectively). A decrease in spherical aberration coefficient was found after CL insertion (P=0.031 monofocal CL; P=0.023 low addition multifocal CL; P=0.016 high addition multifocal CL). Multifocal CL were thicker than monofocal CL (P=0.045). Comparison between groups showed more discomfort in presbyopes than non-presbyopes (P=0.003). CONCLUSION: This study evidence that the behavior of the daily disposable CL with high water content seems to be stable during the day of use. Ocular parameters measured during wear show that CL behavior is the same for presbyopes and non-presbyopes, being more uncomfortable for presbyopes.

    The influence of meibomian gland loss on ocular surface clinical parameters
    (Elsevier, 2019-04-10) Rico del Viejo, Laura; Benítez del Castillo, José Manuel; Gómez Sanz, Fernando Javier; García Montero, María; Llorens Quintana, Clara; Madrid Costa, David
    Purpose: To assess the relationship between the meibomian gland loss (MGL) and relevant ocular surface clinical parameters as well as the influence of age in this relationship. Methods: A total of 161 participants (mean age; 42±17 years) were enrolled in this study. Infrared meibography was performed using Keratograph 5M (K5M; Oculus GmbH, Wetzlar). Participants were divided into five groups according to total meiboscore and the ocular surface parameters of each MGL group were studied. In addition, the relationship between MGL and the ocular surface parameters was established including age as covariant. Results: Both eyelids were taken into account since no association between the MGL from upper and lower eyelid was found (k value=0.2; p=0.3) despite they were significantly correlated (r= 0.3; p<0.001). No statistically significant differences were found in symptomatology among different MGL groups. Statistically significant differences were found among MGL groups in tear osmolarity (p=0.02), bulbar redness (p=0.04), corneal and conjunctival staining (p=0.01 and p=0.004, respectively). Despite this, only corneal staining showed a significant correlation with MGL when age was covariant (r=0.2; p=0.04). Conclusions: MGL higher than 50% seems to be accompanied by signs on the ocular surface. Furthermore, age demonstrated to be a relevant factor when assessing MGL. For this reason, future studies should compare age-matched groups in order to know the contribution of the MGL on the ocular surface and establish valid cut-off values for dry eye diagnosis.

    Innovación docente en Prácticas de la asignatura Optometría V del Grado en Óptica y Optometría de la UCM
    (2021-06) García Montero, María; Hernández Verdejo, José Luis; Vázquez Molini, José María; Gómez Sanz, Fernando Javier; Martínez Alberquilla, Irene
    El desarrollo de las prácticas de esta asignatura tiene un componente teórico previo a la ejecución práctica y, en consecuencia, el uso de material en video que favorezcan un aprendizaje on-line activo, autónomo y colaborativo es de vital importancia en conceptos claves. Además, la resolución de casos clínicos a través de cuestiones auto-evaluativas fomenta el aprendizaje clínico basado en el desarrollo de las consultas optométricas con este tipo de pacientes.

    Aplicación de un programa informatizado para emitir informes clínicos en la asignatura de Clínica Optométrica I
    (2019-06-28) García Montero, María; Hernández Verdejo, Jóse Luis; Madrid Costa, David; Gómez Sanz, Fernando Javier; Lorente Velázquez, Amalia; Rico del Viejo, Laura; Martínez Alberquilla, Irene
    El objetivo es optimizar el uso de un programa informático de registro y almacenamiento de datos clínicos y la creación de una nueva herramienta para generar informes clínicos. Los informes clínicos forman parte de la evaluación del alumno.
