Workshop 4 – Contact lens related complications: diagnosis, classification and optometric treatment Dr.ª Maria Jesús González García Universidad de Valladolid, Spain
The insertion of a contact lens (CL) in the eye, produce a series of alterations in the ocular surface, which can induce complications in a short or long term. This is the reason why the new materials and geometries designed for CL manufacture tend to decrease the interaction between CL and ocular surface, making them more bio compatibles and reducing the number of complications of CL use. However, there are still a number of quite common adverse reactions that force the CL wearers to cease the CL use like giant papillary conjunctivitis, or even with collateral effects such as decrease of vision like microbial keratitis. Some others make the CL wearer to reduce the use like contact lens induced dry eye or adverse reactions to the cleaning solutions. The optometrist has to know how to detect these complications, diagnose them correctly and manage them with all the options we have nowadays. And of course, we do not have to forget how to prevent them, the best managing option the optometrist have. The main OBJECTIVES of this workshop are To identify the most common contact lens related complications in the optometric practice through the recognition of the main clinical signs and symptoms of each condition. To manage, from an optometric point of view, the conditions covered in the workshop. These objectives will be covered through the presentation of case reports, in which the presenter will discuss with an interactive presentation the main characteristics of each of the conditions reviewed. Of each complication, will be covered: Symptoms: what the patient tells us. Completing the clinic history: what the optometrist would ask during the interview for filling in the clinic history. Differential diagnosis: discussion with the audience on what are the more likely conditions that are provoking the symptoms. Signs: what do the observer have look for during the examination (mainly with the slit lamp) for making a correct diagnosis. Cause: what are the main causes of the condition Managing options: what an optometrist can do to resolve the condition.
