NCLE Study Guide with latest updated test. The FDA (Food and Drug Administration) - correct answer.? classifies lens material by how much water is in it and by the electronic charge. The water is either low or high, and percentages are given. The electronic charge is indicated with ionic or non-ionic. The materials are in four groups as follows: The FDA classifies lens material by four groups as follows: - correct answer.Group 1-low water 50% water, non-ionic polymers (this group includes silicone hydrogel polymers) Group 2- high water 50% water, non-ionic polymers Group 3- low water 50% water, ionic polymers Group 4- high water 50% water, ionic polymers The FDA tests disinfectants for their successfulness against these four microorganism groups: - correct answer.•gram-positive cocci •gram-negative rods •yeast •fungi "disposable lenses" - correct answer.The FDA classification for ? means the lens is disposed of after removal. extended wear (EW) - correct answer.The FDA classification for ? is 1 week, Continuous wear (CW) - correct s to wearing contact lenses both during the day and while sleeping for periods of up thirty days and nights consecutively; however the FDA still recommends an overnight removal of continuous wear every 6 nights/7 days. Good Manufacturing Practices (GMP) - correct ards is that part of quality assurance which ensures that medicinal products are consistently produced and controlled to the quality standards appropriate to thei intended use and as required by the marketing authorization (MA) or product specification. GMP is concerned with both production and quality control. FDA approval for marketing - correct answer.All materials are tested, evaluated, and quarantined until all of the standards have been met. Lens blanks are inspected, tested, and quarantined until all of the standards are met and documented. Inspection continues to happen through all stages of production. HIPAA - correct answer.The Health Insurance Portability and Accountability Act of 1996 ("HIPAA") authorized the Department of Health and Human Services to adopt regulations to require certain health providers to limit the use and disclosure of protected health information. The regulations became effective on April 14, 2003. FCLCA - correct answer.The Fairness to Contact Lens Consumers Act became law on February 4, 2004. The Act mandates that eye care practitioners, including optometrists, release contact lens prescriptions to their patients. It also requires contact lens sellers to verify the validity of contact lens prescriptions before releasing contact lenses to consumers. FTC - correct answer.The Federal Trade Commission enforces both the Contact Lens Rule and the Eyeglass Rule. These Rules require that eye care providers give their customers copies of their prescriptions: Contact lens prescriptions must be given to the customers once the lens fitting is complete; eyeglass prescriptions must be given to customers at the end of the eye exam. CDC - correct answer.The Centers for Disease Control and Prevention is working with the Food and Drug Administration (FDA), eye care providers, contact lens and product manufacturers, and academic partners to develop messages about the healthy wear and care of contact lenses. OSHA - correct answer.The United States Occupational Safety and Health Administration is an agency of the United States Department of Labor. Congress established the agency under the Occupational Safety and Health Act, which President Richard M. Nixon signed into law on December 29, 1970. OSHA's mission is to "assure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance". Snellen chart - correct an eye chart used by eye care professionals and others to measure visual acuity. ? are named after the Dutch ophthalmologist Hermann Snellen who developed the chart in 1862. The ? is placed at a standard distance: 20 ft in the US. acuity chart - correct answer.The symbols on an ? are formally known as "optotypes". In the case of the traditional Snellen chart, the optotypes have the appearance of block letters, and are intended to be seen and read as letters. ten Sloan letters - correct answer.Only the ten Sloan letters C, D, E, F, L, N, O, P, T, Z are used in the traditional Snellen chart. The perception of five out of six letters (or similar ratio) is judged to be the Snellen fraction. ANSI standard Z80.20 - 2010 - correct that the tolerance for the overall diameter on a contact lens should be +/- 0.10 ANSI standard Z80320 - correct answer.2010 says the tolerance for the power on a rigid lens that is anywhere from 5.12 to 10.00D is +/- 0.180. It also says that the tolerance for the power on a rigid lens that is less than +/- 5.00 D IS +/- 0.120. Lens inspection verification should show the following - correct answer.Lens inspection verification should show the following Lens Type: Radiuscope: Lensometer: Spherical One base curve Spherical Rx Warped Two base Spherical Rx Front Toric One base Sphero-cylindral Back Toric Two base Sphero-cylindrical Rx Bi-Toric Two base Sphero-cylindrical ANSI standards - correct answer.When lenses are received, ? should be used to check the lenses. The lenses should also be matched up to the record of what was ordered for each specific patient. Shelf life - correct a period of time through which sterility (wet storage) and non-supportiveness of microbial growth (dry storage) are maintained, In addition, parameters of a finished contact lens over this time do not alter in an amount taking the lens outside the tolerances. package configuration. Shelf life is also the duration through which a lens maintains its dimensions, physicochemical material properties.
