Final answer:
Cataracts can be assessed undilated using methods such as slit lamp examination and ultrasound scan.
Step-by-step explanation:
Cataracts can be assessed undilated using various methods. One common method is the use of a slit lamp examination. During this examination, a special microscope called a slit lamp is used to examine the eye. The slit lamp allows the doctor to view the different parts of the eye, including the lens, without the need for dilation. Another method is using an ultrasound scan, which can create detailed images of the eye's structures, including the lens.
