Alternative medicine use
Eyecare specialists need to ask glaucoma patients more about their use of alternative medicine. A study of ophthalmologists across Canada found most either do not ask about alternative medicine use, nor discourage it. Findings were presented by Dr. Tenley Bower from McGill University in Montreal. Dr. Bower said it’s important to ask glaucoma patients about their use of alternative medicines because many can cause glaucoma or interfere with their eye conditions. In many cases, patients may use alternative therapies for their eye condition without the knowledge of their ophthalmologist. A survey was performed on 241 ophthalmologists across Canada. It found a total of 26 per cent asked patients if they use alternative treatments—respondents answered with “always”, “mostly”, or “sometimes”. The study found that those in practice for less than 20 years were significantly more likely to ask their patients about alternative medicine use than those in practice 20 years or more. Most survey respondents, 62 per cent, said they do not discourage alternative medicine use, Dr. Bower said. However, younger ophthalmologists who had fewer years of practice were significantly less likely to discourage alternative medicines than either older ophthalmologists or those with longstanding practices. “When asked about whether or not alternative therapies affect patient compliance with traditional glaucoma therapies, 17 per cent said
The average base curve of an ophthalmic frame is set to about 4 Diopters,while the average Rx strength of the mounted lenses will usually be a cause of excess temple spread due to the natural ?at base curve of the lenses.. One way, and probably the most popular way to avoid excessive spread is to adjust the temples prior to mounting. By doing so, you are enabling yourself to dictate how much spread you think is needed based on the base curve. One way to avoid a potential headache and not to have to manipulate the temples (which some of us will only leave to the pros), is to use surfaced lenses which wi
