The device measures and displays the amount of force that is applied to the eye. ## Device Story The Contact Lens Ophthalmodynamometer is a modified Goldmann three-mirror examination contact lens; it incorporates precision electronic sensors to measure force applied to the eye during fundus, vitreous, and retinal examinations. The device consists of a PMMA curved shell; it transforms physical pressure into electronic signals, which are processed and displayed on an integrated LCD. Used in clinical settings by qualified ophthalmic personnel, the device provides real-time force feedback to the clinician. This measurement assists in standardizing the force applied during ophthalmodynamometry, potentially improving the consistency of diagnostic procedures. ## Clinical Evidence No clinical data. Bench testing was performed to determine repeatability and reproducibility under simulated use conditions; results were within acceptable tolerances. ## Technological Characteristics Materials: PMMA (acrylic plastic). Sensing: Electronic sensors for force measurement. Output: LCD display. Geometry: Goldmann three-mirror (59/66/73 degrees). Standards: EN/IEC 60601-1 (safety), EN/IEC 60601-1-2 (EMC), ISO 13485 (quality), ISO 14971 (risk management). ## Regulatory Identification A polymethylmethacrylate (PMMA) diagnostic contact lens is a device that is a curved shell of PMMA intended to be applied for a short period of time directly on the globe or cornea of the eye for diagnosis or therapy of intraocular abnormalities. ## Predicate Devices - Haag-Streit Contact Glasses ([K051103](/device/K051103.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

FDA may make this summary available to the public within 30 days following a finding of substantial equivalence. #### 510(k) Applicant Meditron GmbH Postrasse 19-21 D-66333 Voelklingen, Germany #### 510(k) Correspondent Robert N. Clark, President and Senior Consultant Medical Device Regulatory Advisors 13605 West 7th Ave., Golden, CO 80401 USA #### Date Prepared May 19, 2006 #### Trade Name of Device Contact Lens Ophthalmodynamometer #### Classification Name Polymethylmethacrylate (PMMA) diagnostic contact lens #### Classification Regulation: 21CFR§886.1385 Product Code: NYK, Class II #### Device Description The Meditron Contact Lens Ophthalmodynamometer is a classic Goldmann three-mirror examination contact glass that has been adapted with precision electronic sensors for continuous measurement of pressure applied to the eye. Electronic signals from the sensors are used to determine pressure values, which are then displayed on the device's LCD display. The patient contact portion of the examination glass consists of a curved shell of acrylic plastic (PMMA) that is applied for a short period of time directly on the globe or cornea of the eye. PMMA is commonly used as a material in examination contact glasses having the same intended purpose. {1}------------------------------------------------ | Meditron GmbH | 510(k) Number: | K052674 | |-----------------------------------|----------------|--------------| | Contact Lens Ophthalmodynamometer | Date: | May 19, 2006 | | | Page 2 of 2 | | The mirror angles are the same as the original Goldmann and predicate devices: 59/66/73 degrees. #### Intended Use The device is indicated for examination of the ocular fundus, vitreous and retinal structures, while manually applying force to the eve with the contact lens. The device measures and displays the amount of force that is applied to the eye. #### Predicate Device K051103 - Haag-Streit Contact Glasses manufactured by Haag-Streit USA Inc, Mason, Ohio. #### Voluntary Standards EN 60601-1 / IEC 60601-1. "Medical Electrical Equipment - Part 1: General Requirements for Safety" EN 60601-1-2 / IEC 60601-1-2, "Medical electrical equipment -- Part 1-2: General requirements for safety - Collateral standard: Electromagnetic compatibility - Requirements and tests" ISO 13485:2003, "Medical devices - Quality management systems - Requirements for regulatory purposes" ISO 14971, "Medical devices - Application of risk management to medical devices" ### Laboratory Testing Repeatability and reproducibility of the device was determined under simulated use conditions. All results of the study were within acceptable tolerances. #### Risk Management This device has been designed to either completely eliminate or mitigate known health hazards associated with the use of the device. Health hazard risk reduction has been accomplished by rigorous application of a risk management program. The user must be qualified in ophthalmic examination procedures, and must be familiar with all labeling and instructions for use associated with the device. Meditron GmbH believes that the Contact Lens Ophthalmodynamometer is safe and effective when used as instructed by knowledgeable and trained personnel, and is substantially equivalent to the legally marketed predicate devices. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image is a black and white circular logo.
