Lightweight and adjustable ophthalmic trial frame designed to securely hold multiple trial lenses during subjective refraction, enabling comfortable subjective refraction and vision assessment in ophthalmology and optometry practice.
The IndoSurgicals Trial Frame is an essential ophthalmic examination instrument used during subjective refraction to determine the optical correction required by a patient.
Designed to accommodate multiple trial lenses, the frame enables an ophthalmologist, optometrist or eye-care professional to introduce different spherical, cylindrical, prism and other trial lenses while evaluating the patient's visual response.
Its lightweight combination of metal and plastic, adjustable temple length and pupillary distance adjustment are intended to provide secure positioning and patient comfort throughout the examination.
Accommodates multiple trial lenses simultaneously, supporting efficient lens combinations during refraction testing.
Sliding bridge adjustment allows lens centres to be aligned according to the patient's pupillary distance for appropriate lens alignment during refraction.
Temple length can be adjusted to accommodate different head sizes and improve stability during examination.
Metal and plastic construction provides a practical balance of durability and reduced weight.
The frame is designed to remain securely positioned while lenses are changed during the refraction process.
Straightforward adjustments make the frame convenient for routine examination, teaching and clinical practice.
A trial frame is used together with a trial lens set during subjective refraction. Different optical lenses are positioned in front of the patient's eyes while the examiner evaluates changes in visual acuity and patient response.
Trial lenses can be introduced and exchanged in the frame while the patient views an appropriate visual acuity target. This enables the examiner to refine spherical and cylindrical correction according to the patient's responses.
The ability to hold multiple lenses makes it possible to evaluate combinations of trial lenses without repeatedly removing the complete optical setup.
Proper lens positioning is important during refraction. The IndoSurgicals Trial Frame incorporates an adjustable pupillary distance mechanism so that the optical centres of the trial lenses can be aligned appropriately with the patient's visual axes.
Adjustable temples help accommodate differences in head size, while the stable bridge assembly supports consistent positioning throughout the examination.
Place the frame comfortably on the patient and adjust the temples to achieve a secure and stable fit.
Adjust the sliding bridge mechanism so that the trial lens positions correspond with the patient's pupillary distance.
Place the required trial lenses into the appropriate lens holders according to the refraction being evaluated.
Change or combine trial lenses according to the patient's visual response until the desired refractive correction is determined.
Patient comfort is particularly important during subjective refraction because several lens combinations may need to be evaluated before the final correction is determined.
The lightweight construction of the IndoSurgicals Trial Frame helps reduce unnecessary pressure during testing, while the adjustable temples allow the frame to accommodate patients with different facial and head dimensions.
Its simple design also makes it suitable for routine examinations, teaching applications, basic refraction requirements and use as an additional or backup trial frame in ophthalmology and optometry practice.
