A scan TW-1000A

A-scan ultrasonography, or A-scan, is a fundamental tool in ophthalmology for assessing various aspects of the eye’s anatomy, particularly in preoperative evaluations for cataract surgery and diagnosis of certain eye conditions. By emitting high-frequency sound waves and measuring their reflections, A-scan provides detailed information about the size and shape of ocular structures such as the lens, cornea, and vitreous chamber. This non-invasive technique aids in determining the power of intraocular lenses needed for cataract surgery. With its accuracy and versatility, A-scan plays a crucial role in ensuring precise surgical planning and optimal patient outcomes in ophthalmic practice.
