Lenticular astigmatism is a common eye disease, usually caused by the early formation of cataracts, where the lens becomes unevenly opaque. This leads to inconsistent refractive power in different directions, causing astigmatism. Patients can visit the ophthalmology department of a hospital for an optometry examination and a slit lamp microscope examination to confirm whether the astigmatism is due to the lens.

For lenticular astigmatism, if the cataract has little impact on vision, it can initially be corrected by wearing glasses to improve vision. If the cataract has already significantly affected vision, cataract surgery can be performed to correct and treat it. After the surgery, the lenticular astigmatism will naturally disappear, and the patient’s vision will be improved.
