Children born with cataracts in both eyes undergo surgery and their visual problems are corrected with contact lenses. However, they often experience problems with visual processing when they are adults. Fortunately, scientists have found a way of dealing with such problems.
The newest studies show that visual processing issues can be resolved with the use of video games. According to Dr Daphne Maurer, a psychologist from McMaster University, after playing an action game for approximately forty hours in the period of four weeks, the participants of the study could read small print and identify faces much better than before, which suggests that the adult brain is able to overcome certain sensory deficiencies.
In her work, Dr Maurer also deals with the phenomenon of synaesthesia, which consists in mixing different senses, resulting in, for instance, patients hearing colours. Her research improves our understanding of how perception and language develop and, for example, has proven that partial synaesthesia is a normal developmental phase exhibited by babies and toddlers.

According to Dr Takashi Kojima and Dr Murat Dogru, guest writing for Contact Lenses Today, Japanese contact lens wearers usually choose two weekly or daily contact lenses. More and more of them, the experts state, wear lenses made of silicone hydrogel material.
ls instead of conventional ones and it is believed that the trend will continue.
As far as contact lens solutions are concerned, multipurpose ones seem to be preferred. However, there are still a number of cases of corneal infections related to contact lens use. In the experts’ opinion, they result from improper use of disinfectants and the situation can be improved by increased patient education regarding maintaining and handling contact lenses.
During last year’s earthquake, Japanese ophthalmologist were faced with numerous problems, helping victims wearing contact lenses, the most common of which was that many contact lens users did not know the exact power of their lenses. This, the experts believe, shows how important patient education is.

Several researchers (led by C.W. McMonnies) have conducted a study to create guidelines regarding contact lenses users’ hand hygiene that would constitute an effective compromise between safety (minimisation of the risk of infection) and convenience.
The study was based on data acquired from publications found through PubMed, Advanced Medline Search, Cochrane Reviews and Google Scholar, which showed that recommendations concerning washing hands depend on the required level of hygiene. In addition, the researchers discovered – taking the levels of non-compliance among healthcare employees into account – that too demanding guidelines result in more patients failing to follow them.
The conclusions that the authors of the study reached were that non-compliance levels can be decreased if patient education related to hygiene is better. Furthermore, the guidelines need to be changed so that the perception of ‘too much bother’ is reduced, leading to more patients willing to follow them.
The guidelines that the researchers prepared included explanations, as they should help contact lens wearers to understand the importance of hand hygiene and motivate them to adopt the recommendations.
