Changes in visual quality with soft contact lenses after the instillation of hyaluronic acid eye drops
Hyaluronic acid (HA) is a natural polysaccharide which is mainly present in the connective tissue of vertebrates [1]. It is a versatile biomolecule with many applications in biomedicine due to its ability to act as a lubricant agent, its viscoelastic properties and water holding capacity [2]. Eye drops with viscous agents are used for the treatment of dry eye due to their capability of regenerating the ocular surface damage [3,4]. For this reason, HA is incorporated to eye drops not only for dry eye treatment but also for relieving ocular dryness symptoms associated with environmental factors.

Visual performance with multifocal contact lenses and progressive addition spectacles
As presbyopia occurs, new visual demands create a need for clear vision at multiple distances. Many spectacle wearers adapt into progressive addition lenses (PAL) in order to see clearly at distance, intermediate, and near. A multifocal contact lens provides the ability to see at these same distances without the prismatic effects of a spectacle lens or the peripheral obstruction of a spectacle frame. No studies have been done to date comparing the effect of these types of presbyopic vision correction on a variety of tests of visual performance representative of everyday tasks.

Assessment of four validated questionnaires for screening of dry eye disease in an African cohort
To evaluate the 5-item dry eye questionnaire (DEQ-5) for measurement precision and unidimensionality, and assess the ability of Ocular Surface Disease Index (OSDI), McMonnies Dry Eye Questionnaire (MQ), Ocular Comfort Index questionnaires (OCI), and DEQ to predict clinical measures of DED in an African population.
