In this article, I'll review how employing a certified technician with skills in a subspecialty area like contact lenses can boost both your business and patients' satisfaction. The certified technician will be schooled in all of the basic principles of contact lenses, fitting procedures, and verification of lenses.

She will know how to work through patient education and how to troubleshoot problems before the physician's examination. Working Together Ophthalmologists value sharing the patient workload with a specially trained CL technician. In most cases, the tech will be able to spend more time with a contact lens wearer than the physician can.

The ophthalmologist has to be careful to balance the responsibility for the contact lens patient so the patient doesn't feel neglected by the physician. The tech is better at some things; I must do other parts. We're working together. Contact Lens Assessment The introduction of contact lens wear to a new patient should be a conversation between the ophthalmologist, the technician and the patient. The physician's exam will raise any red flags about contact lens wear.

These are issues the ophthalmologist should be addressing with the patient, with the technician in the loop," she says. The Technician's Role The tech can play an important role in the decision-making process for contact lens fitting. Often the technician, more so than the ophthalmologist, has current knowledge about lens styles, materials and patient demands. She says that a good tech can handle this complex fit, which combines refractive error and accommodative issues. The knowledgeable technician will recommend lenses based on individual needs," she explains.

Hard Contact Lenses

At the upper levels of certification, testing includes computer simulations that examine technique, process and the ability to read results. She explains that, at the Certified Ophthalmic Medical Technologist level, candidates are tested in front of two evaluators, usually an ophthalmologist and another high-level ophthalmic allied health technologist.

These testing methods assure a certain level of knowledge and skill. Courses and training in the contact lens specialty are available through the Joint Commission on Allied Health Personnel in Ophthalmology jcahpo. After the technician has identified the patient's needs and fit some trial lenses, the ophthalmologist should come back in and review everything, says Dr.

Insert coupling fluid into cup of contact lens but do not overfill 4. Ask patient to look up , insert inferior rim of the lens into lower fornix and press it quickly against the cornea 5. When viewing different positions of peripheral retina, rotate axis of beam so that it is always at right angles to the mirror To visualize entire fundus, rotate lens for degrees using the 59, 67 and 73 degrees tilted mirrors to give views of the peripheral retina, the equatorial fundus and the area around the posterior pole, respectively 7.

To obtain a more peripheral view of the retina, tilt the lens to the opposite side and ask the patient to move the eyes to the same side. Examine the vitreous cavity with central lens, using a horizontal and a vertical slit — beam and then examine posterior pole Thus light rays from the anterior chamber angle enter the contact lens and are then made to pass through the new contact lens-air interface Goldmann single mirror gonioprism 2.
